2. Kneel for articles or poems praising chemical fertilizers, and emphasize the characteristics and applications of commonly used compound fertilizers. Compound fertilizer is rich in nutrition and can be divided into binary and ternary; Most of them have good physical properties and are convenient for transportation and storage.
Diversification and flexible application of the three elements are the key; Recently, the promotion of formula fertilizer has been diversified. (1) monoammonium phosphate is acidic, with 42 phosphorus and 1 1 nitrogen.
China's soil is alkaline and suitable for urea mixed with monoammonium. Nitrogen and phosphorus complement each other to improve fertilizer efficiency, save labor and money, and have high yield.
If farmers want to benefit more, they will use it to produce formula fertilizer. (2) Diammonium phosphate Diammonium phosphate is alkaline, containing 46 phosphorus and 18 nitrogen.
The content of diamine made in China is low, 45 phosphorus 13 nitrogen. The effect of applying monoammonium in acidic soil is better than that in alkaline soil.
It is best to mix urea when applying, so that the yield can be increased while using it. (3) Monoammonium Phosphate, Diammonium Phosphate, Forty-six Phosphorus and Fifteen Nitrogen.
The particles are gray and neutral, and can release nitrogen when meeting alkali. Suitable for all kinds of soil, both base fertilizer and topdressing.
The most suitable crops are wheat and rice, as well as soybeans and corn. (4) The process for producing liquid ammonium phosphate is simple and the cost is low.
Nitrogen contains seven phosphorus and twenty phosphorus, which is easily soluble in water-based acids. Good suspension performance, no corrosion and no precipitation.
The application range is wide and the prospect is bright, so nitrogen application is needed. (5) ammonium metaphosphate ammonium metaphosphate is neutral, and its nature becomes weakly acidic and soluble.
An acidic field should be applied to promote its hydrolysis to monoammonium. Seventy-five phosphorus and sixteen nitrogen should be increased by physiological acid.
The particles are gray, non-caking, and easy to store and transport. (6) Nitrophosphate Nitrophosphate is slightly acidic and its compound components are phosphorus and nitrogen.
Twenty-six nitrogen and thirteen phosphorus, the most moderate wheat field. Because it contains nitrate nitrogen, it is best to apply it in dry fields.
Ammonia will be released when it meets alkali, and storage and transportation should be strictly controlled. (7) The physical and chemical properties of ammonium superphosphate have changed greatly.
Neutralize most free acids, which is convenient for use, storage and transportation. Soluble in water, neutral, add 3% ammonia water.
Never mix alkaline substances. Soybean green manure is the favorite. (8) Ammonium sulfate, ammonium sulfate, acid in nature, 20 phosphorus and 16 ammonia.
Soluble in water and fertilizer, containing ammonium sulfate and ammonium phosphate. The soil in China is alkaline, and the application benefit is obvious.
Suitable for all kinds of crops, wheat should be increased in nitrogen. (9) Potassium dihydrogen phosphate compound fertilizer potassium dihydrogen phosphate is suitable for root spraying.
Fertilizer per mu100g or more, and the seeds that mature in advance are large. It contains 52 phosphorus and 34 potassium; Soluble in weakly acidic water, it can also be used for seed dressing.
(10) Ca-Mg-P-K fertilizer is a new type of Ca-Mg-P-K fertilizer, and its gray powder is alkaline. Potassium contains phosphorus and seventeen, and also contains calcium and magnesium fertilizers.
Insoluble in water-soluble weak acid, suitable for calcium deficiency acid field. It is best to compost before use to improve fertilizer efficiency and obtain high yield.
(1 1) potassium metaphosphate is similar to potassium phosphate compound fertilizer, and its nature is weakly acidic ash particles. Phosphorus is as high as 59 and potassium is as high as 37.
It can dissolve weak acid, slightly soluble in water, and acid application is the most suitable. Because nutrients are short of nitrogen, nitrogen fertilizer should be mixed when applying.
(12) Potassium nitrate Potassium nitrate, called mirabilite, has good white crystalline properties. If carbon and sulfur are mixed, it will be flammable and explosive. Soluble in water, neutral, can be used for seed dressing.
Forty-four potassium and thirteen nitrogen, topdressing outside the root can increase yield. (13) N-K compound fertilizer, ammonium sulfate mixed with potassium sulfate, produced by ammonia-alkali method, hexadecylamine is easily soluble in water physiological acid.
Suitable for all kinds of soil, and alkali will not be encountered during storage and application. Due to the lack of phosphorus in nutrients, increasing the application of phosphate fertilizer is the key.
(14) ternary compound fertilizer of ammonium, phosphorus and potassium, in which ammonium, phosphorus, sulfur and potassium are added in two phases; Ammonium sulfate is also added, and the products are divided into one, two and three grades; The number 1 contains nitrogen 12, potassium 12, and the phosphorus content can reach 24. No.2 nitrogen, no.10 potassium and no.15 phosphorus can reach no.20 hydrogen.
No.3 nitrogen and potassium are all ten, and phosphorus is as high as thirty. According to the needs of crops, fruit trees should be used economically.
(15) Four kinds of potassium nitrophosphate can be produced by adding potassium nitrate; First, frozen nitrophosphate, the content of three elements is similar; Nitrogen, fifteen kinds of phosphorus, sixteen kinds of phosphorus and seventeen kinds of potassium oxide. The second is nitrophosphate, which contains nitrogen, pentapotassium and octapotassium; More than 90% of phosphorus is soluble, and acidic soil is very suitable; Carbon dioxide replaces sulfuric acid, reducing cost and price.
The third is nitrophosphate, and Panax notoginseng fertilizer is effective. All the above three kinds contain chlorine, so don't use tobacco cane potatoes.
Fourth, there is no phosphorus and potassium chloride, and potassium sulfide is used instead of potassium chloride; Because of the high production cost, cash crops use it. (16) urea-potassium-phosphate fertilizer, urea, potassium and phosphorus are adjusted into three elements, and nitrogen, phosphorus and potassium fertilizer are all nutrients; Production uses potassium nitrate, molten urea and hydrazine.
There are fourteen kinds of phosphorus and potassium and twenty-eight kinds of nitrogen; Nitrate, nitrogen, ammonium, nitrogen and hexadecane are amides. Because of the comprehensive nitrogen, the economic fields of fruit trees are reused; Because nitrogen and phosphorus are two to one, the wheat field is milder.
Mineral fertilizer Mineral fertilizer is applied early, and lime and gypsum are commonly used. There are brine and agricultural salt, and ferrous sulfate is called black alum.
It mainly regulates soil utilization and improves soil physical and chemical properties. Beneficial reproductive microorganisms can be provided directly or indirectly.
(1) Limestone ash can be cooked separately, which is suitable for improving acidic soil. The south is gray-red and yellow soil, and the northeast is acidic soil with white pulp.
Application can not only supplement calcium, but also reduce pests and diseases. Master the yield per mu 100 kg, and don't mix the urine and feces of people with calcium superphosphate.
(2) Gypsum Gypsum is acidic in nature and is used to improve alkaline soil. Both raw phosphate rock and cooked phosphate rock contain calcium and sulfur.
Apply 50,000 grams per mu on dry land to cultivate deep and fine fertilizers and improve the soil. The paddy field needs three kilograms, which is mainly used for dipping seedling roots.
(3) Brine Brine has complete nutrients, such as potassium, sodium, calcium, magnesium and nitrogen. Dark brown liquid is heavier than water and is suitable for sandy soil and paddy field.
Applying 50 kilograms per acre will increase the yield of various crops. Brine paste is dark brown crystal, easily soluble in water and strong alkaline.
(4) Sodium chloride, an agricultural salt component, also contains boron, iodine, sulfur, magnesium and potassium. White crystals are neutral, and sodium is used in magnesium and potassium crops.
Rice, wheat and soybeans all like sodium, as well as beets and flax. Only five kilograms per mu is needed, and the mixed human urine fertilizer has great effect.
(5) Medical stone Medical stone is rich in nutrition and can be used for health care in ancient times; "Compendium of Materia Medica" records that the authentic origin is Songshan. Recently used as feed and fertilizer to increase production; Adding sulfuric acid before fertilization can solve the problem of difficult absorption of crops.
