Planting technique
I. Botanical characteristics
Ginger root system is underdeveloped and shallow, mainly distributed in the range of about 30 cm. The stem is a fleshy rhizome, and the axillary buds can differentiate once, twice and thrice. Secondary rhizomes are clustered into blocks. Generally, the more seedlings, the bigger the ginger pieces and the higher the yield. The aboveground stems are pseudostems formed by leaf sheaths, with a height of 70- 100 cm, and are upright and unbranched. Leaves lanceolate, sheathed, green, alternate leaves, arranged in two rows. Ginger can bloom in the tropics, with yellow-green or red flowers, which rarely bear fruit and reproduce by roots.
Second, the requirements for environmental conditions
Jiang likes warm and humid environmental conditions and is not resistant to low temperature frost. Germination begins above 16℃, the suitable temperature for seedling growth is 20-25℃, the suitable temperature for stem and leaf growth is 25-28℃, and the growth stops below 15℃. The annual temperatures in Mudu, Zhuangke, Anahei and other village committees are basically above 15℃, and the lowest hot valley area is very suitable for the growth of ginger, and the yield is also relatively high.
Ginger prefers weak light to strong light. Leaves wither easily under strong light. There is an agricultural proverb called "ginger basking in the sword (new leaves) equals death". The requirement of sunshine length is not strict.
Ginger likes loam which is fertile and loose, rich in organic matter, convenient for irrigation and drainage, and slightly acidic in soil. Strict requirements for water, not early and not resistant to theft, premature exposure will cause stem and leaf withering, poor growth, high temperature and humidity, poor drainage and easy to cause disease. For the demand of three elements, potassium is the most, followed by nitrogen and phosphorus is the least.
Three. Types and varieties
Rhizome nodes are many and dense, and there are many ginger slices, which are arranged in two or more layers. The representative varieties are Guangdong Miren fine meat ginger, Yuxi turmeric in our province and Xichou fine ginger. In addition, according to the skin color of ginger, it can be divided into white ginger, purple ginger, green ginger (also known as water ginger) and turmeric. Dioscorea longqing has medium growth and many branches, belonging to close planting type.
Fourth, cultivation techniques.
(1) Cultivation system and season: Ginger can be planted in net or intercropped. Longqing Dioscorea zingiberensis was generally planted in sericulture fields around Tomb-Sweeping Day.
Intercropping can be planted under tall crops, such as melons and beans, and can also be intercropped between rows of corn to provide shade.
(2) Land selection, soil preparation and fertilization: Ginger should avoid continuous cropping, and it is best to rotate with rice, onion and garlic, and choose loam or sandy loam with deep, fertile and loose soil layer and good drainage. Ginger is afraid of strong light and should be planted in a suitable shade. Ginger has a long growth period, high yield and large amount of fertilizer. The agricultural fertilizer per mu is not less than 3000 kg, and 20 kg of artificial potassium sulfate or 30 kg of compound fertilizer is used as base fertilizer to fully meet the nutritional needs of ginger. Borders are generally made into high borders.
(3) Seed selection and sowing: Before sowing, carefully select ginger seeds and remove moldy, rotten and withered ginger slices. It is better to choose ginger with 50- 100g and 1-2 strong buds for planting ginger. Large Jiang Ye can be planted, but the amount of seeds is large and the cost is high. It can be cut with a knife or opened by hand, but the wound should be disinfected with plant ash or lime before sowing. Before sowing, it is best to soak the seeds with chemicals to accelerate germination. Methods Ginger was spread and dried for 65,438+0-2 days, and then soaked in 65,438+0:1:65,438+020 Bordeaux solution for 65,438+00 minutes. Then, after the ginger is taken out, it is layered with wet sand, covered with a film with a thickness of about 30-40 cm, and the temperature is kept at 20-30. The amount of seeds used per mu is 300-500 kg.
Generally, the row spacing of ginger is 35-40 cm, the plant spacing is 26-30 cm, and the ditch depth is 10- 12 cm. Sowing in the pool can be carried out according to the plant spacing of 33 cm and the depth of the pool of 7-8 cm.
After digging ditches and ponds, put ginger seeds obliquely, arrange the buds in one direction, cover them with fully decomposed farm manure or soil miscellaneous fertilizer, with a thickness of 6-8 cm, and then cover them with a small amount of soil.
(4) Field management: After ginger is discharged, if the soil is wet, it can germinate without watering. If the soil is dry, water it once, but not too much. After germination, water according to soil moisture and plant appearance. Early watering and late watering should be advocated in high temperature period, and drainage should be paid attention to in rainy season.
During the growth period, ginger should be cultivated by intertillage and forced fertilization for many times. When the seedling height is about 15 cm, it is suitable for intertillage weeding cultivation. Top dressing is mainly human excrement and urine, and the cultivation is 3 cm. With the increase of tillering, each seedling should be forced to apply fertilizer once, and the thickness of soil cultivation should be 3-4 times without burying the seedling tips, so that the original planting ditch can be turned into a ridge. Soil culture can inhibit excessive tillering and make ginger slices hypertrophy.
Ginger is afraid of strong light, so it is feasible to interplant corn or beans, or put it in a shade shed or insert branches and wormwood stems for shade.
(5) Pest control: The pest is corn borer, and the disease is mainly ginger rot, which mainly harms leaves and roots, especially at high temperature. Prevention and control methods: rotation, disease-free ginger, irrigation, to prevent water from the diseased areas. The pesticide can be used once every 7- 10 days, which is 800 times that of 50% zineb.
Fifth, harvest the seeds.
Ginger is cultivated in one season and eaten all year round. July-August can be harvested one after another. Early harvest yield is low, but the output value is high. In production practice, vegetable farmers harvest in stages according to market needs.
(1) Collecting seed ginger, also known as "stealing ginger", refers to harvesting old ginger (that is, ginger) when the plant grows to 5-6 leaves. The method is to pry open the soil with a hoe or shovel, gently remove the planted ginger, immediately cover the soil and topdressing it in time. There is no loss in planting ginger, so there is a saying in agricultural proverbs that "ginger is enough to lose money"
(2) After harvesting tender ginger, beginning of autumn can harvest new ginger, that is, ginger, which is fat and tender and suitable for fresh food processing. The earlier the harvest, the lower the output, which is mainly determined by the law of market value.
(3) Harvest of ginger: Before and after the first frost, the stems and leaves turn yellow and can be harvested. At this time, the harvest yield is high and the spicy taste is heavy, which can be stored, processed, eaten and stored. In the frost-free area in the south, the stems and leaves on the ground can be cut off and covered with straw, and the seeds can be harvested or reserved at any time as needed, but the soil moisture should not be too high.
Taneda should plant ginger, and apply more phosphorus and potassium fertilizer and less nitrogen fertilizer during the growing period. Harvest in sunny days, select ginger slices with thick and full roots and no diseases and pests, store them separately, and check them regularly during storage to pick out sick and bad ginger.
[medicinal properties of traditional Chinese medicine]
Ginger is pungent and warm, good at dispelling cold, resolving phlegm and relieving cough, and can stop vomiting and detoxify. Clinically, it is often used to treat exogenous wind-cold and stomach-cold vomiting, and it is called "the holy medicine for vomiting at home" by predecessors. Ginger frying is to make use of these characteristics of ginger and use ginger juice as an auxiliary material to process drugs, so as to enhance expectorant and antitussive effects, reduce adverse reactions and vomiting, and reduce its toxic and side effects. If bamboo shavings are good at clearing away heat and resolving phlegm, ginger roasting can enhance the effect of reducing adverse reactions and stopping vomiting; Magnolia officinalis is spicy and irritating to the throat. Its side effects on throat irritation can be eliminated by baking ginger, and the effect of soothing the stomach can be enhanced. Rhizoma Coptidis and Rhizoma Zingiberis Recens can relieve their bitterness and coldness and treat vomiting caused by stomach heat.
Although dried ginger is the same as ginger, its properties are different because of the different qualities of fresh dried ginger. Dried ginger is hot, pungent, strong, good at warming the middle and returning to yang, and can warm the lungs and dissolve the drink. Clinically, it is often used to treat symptoms such as deficiency and cold of middle energizer, impotence and dyspnea caused by cold drinks. Therefore, the performance of ginger juice prepared with dried ginger is different from that of raw ginger juice. If ginger juice made from dried ginger is used to process drugs, it will affect the processing effect of drugs. If the purpose of drug processing cannot be achieved, the efficacy of drugs with antiemetic effect will not be enhanced.
According to the theory of traditional Chinese medicine, ginger is a product that helps yang. Since ancient times, Chinese medicine has always said that "people can't live without ginger for a hundred days." Su Shi, a poet in the Song Dynasty, described an 80-year-old monk in Jingci Temple, Qiantang, Hangzhou, with a childish face. "He persuaded Jiang for forty years, so he is not old." Legend has it that White Snake stole Xiancao to save Xu Xian. This fairy grass is ginger bud. Ginger is also called "rejuvenation grass" and ginger soup is also called "rejuvenation soup".
Jiang's surname comes from the surname of Emperor Yan in ancient times.
According to historical records, Jiang is a descendant of Emperor Yan and one of the oldest surnames in China.
Shuo Wen Jie Zi said: "Shennong lives in Jiang Shui and thinks his surname is his own." The legendary Emperor Yan, Shennong, is said to be one of the oldest "Huang San" in China history. A native (now Qishan County, Shaanxi Province) took Jiang as his surname. So the birthplace of Emperor Yan is also the birthplace of Chiang Kai-shek.
Later, in the course of history, due to various reasons, many descendants of Emperor Yan changed their surnames. The descendants of Emperor Yan were either sealed in Shandong (now Nanyang County, Henan Province) or sealed in Shenyang in rainy summer.
Qi was one of the five tyrants in the Spring and Autumn Period, founded by Lu merchants. History records: "Lu Shang, surnamed Jiang Mingya." Lu Shang, a descendant of Shennong (also known as Jiang Taigong and Jiang Ziya), was named Lu Shang because his ancestors tasted four mountains and helped Dayu control water. His descendants inherited the monarch of the State of Qi and lived for the 29th time. Later, during the Warring States Period, Qi was destroyed by Tian He, and Qi became Tian's regime. His descendants are scattered all over the country, taking Jiang as their surname. In this way, the surname Jiang, who moved to various places, continued to multiply and develop, and by the Han Dynasty, it had developed into a big family.
According to historical records, as early as the Spring and Autumn Period, Xirong also had a surname of Jiang, so it was called Jiang Rong, originally in Guazhou (now Dunhuang West, Gansu Province), and then gradually moved eastward. Around 638 BC, its leader moved to southern Shanxi and belonged to the State of Jin. Jiang lived in today's Shandong and Henan provinces, and had developed into a Kanto family before the Western Han Dynasty (the area east of Hanguguan in Lingbao County, Henan Province). In the early years of the Western Han Dynasty, in order to enrich the population of Guanzhong, Jiang moved from Guandong to Guanzhong. This younger generation lived in Tianshui (now Gansu), so the people took "Tianshui" as the county name. By the Han Dynasty, Jiang's family had migrated to Jiangsu and Sichuan. However, until the Tang Dynasty, Tianshui was still the development and reproduction center of the Chiang family. During the Tang and Song Dynasties, the Chiang family was also distributed in Hebei, Henan, Zhejiang, Jiangxi, Anhui, Shandong, Qiongshan, Guangdong and other places. During the Ming and Qing Dynasties, some members of the Jiang family lived in Shanxi, Shaanxi, Hunan, Guizhou, Hubei and other places. According to Jiang's genealogy, during the Hongwu period of the Ming Dynasty, a man named Jiang Shiliang moved to Hongdu Village, Longxi County, Zhangzhou, Fujian Province, and made a fortune here. Its descendants multiplied, and the other branch moved to Yandun Township, Lufeng, Guangdong Province, and continued to prosper. Later, Jiang Shiliang's grandson 1 1 moved from the mainland to Taiwan Province Province during the Qianlong period of the Qing Dynasty. Since then, people from Fujian and Guangdong have moved to Taiwan Province Province, and some people have spread overseas.
Jiang's celebrity was Jiang Ziya of the Zhou Dynasty. Since then, many outstanding figures have appeared in the past dynasties. Jiang Kang, a hermit in the Eastern Han Dynasty, was called "a famous historical family". He is not only knowledgeable, but also famous for his filial piety with his second brothers Zhong Hai and Yoshioka. Brothers love each other and often sleep together. Later generations often use "Jiangbei" as a metaphor for brotherhood. There was the Jiang family in the Eastern Han Dynasty, which was famous for its filial piety to his wife, and later developed into a more prosperous branch of the Jiang family.
In the Three Kingdoms, there was a man named Jiang Wei, a native of Tianshui, who was originally a general of Wei, and later returned to Shu, winning the trust of Zhuge Liang. After Zhuge Liang, he led the army as a general. He is a famous minister. In the Tang Dynasty, there were two prime ministers named Jiang, besides Jiang Gongfu, there were other prime ministers named Jiang Ke. There was a famous poet and musician in the Southern Song Dynasty, who was a Taoist of Baishi, Jiang Kui, and a native of Poyang (now Boyang, Jiangxi). He was proficient in poetry, music and economy. Unfortunately, because Qin Gui was in power at that time, Jiang Kui spurned him and lived in seclusion. There was also a famous Jiang Cai in the Southern Song Dynasty. There was a painter Jiang Ligang in Ming Dynasty; Jiang, a writer in Qing Dynasty, once participated in the compilation of Ming History. His criminal record exposed the harm of "factory guards" in the Ming Dynasty, and he was good at calligraphy and poetry, and was known as one of the "Three Cloth Clothes in the South of the Yangtze River". In modern times, there were the Red Army in northwest Anhui and Chiang Ching-tang, one of the founders of revolutionary base areas.
Jiang's surname ranks 60th among the top 100 surnames in China.
