Looking through Wang Zhennong's Book, I found that there was a "bucket" in the Atlas of Agricultural Tools. I was surprised and hurried through it. The text under the entry is simple. First of all, there is a sentence: water scoop. He said that cars are not allowed to be bought in places where the water bank is lower. In times of drought, it is to use buckets and double buckets to control, and two people slap each other and express the water ashore to irrigate the fields.
Isn't this the farm tool used by every household in our country? ! I've used it since I was a child. It was difficult at first, and people didn't have much strength. The opposite one pushed a little harder and fell into the water. Later I used it very skillfully. In the third grade of primary school, I can fetch water with my mother all day without feeling tired. It's just that next to the finger is a nylon rope (that is, an industrialized cup), which often grinds blisters. The blister is broken, sour and painful.
Wang Zhen, a native of the East, recorded all the products and appliances in the north in his Agricultural Book. It can be seen that fighting is a peaceful thing in the north and slowly spreads to the south. The water system in the south is developed and irrigation is not difficult, but as long as the fields are above the water level, water must be delivered by manpower. The waterwheel is probably the most famous irrigation tool, and even children know it:) The waterwheel can be operated by one person. I tried, it tested my arm strength, and it didn't work, but I like to watch the waterwheel pump water. The wooden paddle jumps into the water smoothly, and the water rises with a gurgling sound, which is very rhythmic. It takes two people to fight, but if the water is not low, a good farmer can use it alone and I can use it, but it can't last, so I'm not a good farmer.
"Agricultural Book" says that buckets can be woven with wicker. I've never seen such a bucket. Wicker barrel should be an excellent proof of the ancient handicraft industry in China. Can you imagine a wicker basket? The bucket used in our village has a wooden hoop, but it is of little use. Wood is lighter than water. Diving and scooping water require extra skill and strength. Plastic buckets are widely used. Plastic buckets are bought from supply and marketing cooperatives or individual stores, passed through wooden sticks and tied with four ropes, which is the finished product and can be used.
Paddy fields are extremely water-consuming, so they need irrigation the next day. On a foggy morning, dew hung on the grass tip. After walking for a while, my pants were wet. Then the sun came up, the fog and dew disappeared, and then it became hot. I can't go home until noon.
Carrying water is extremely time-consuming and laborious. If there is a paddy field irrigated by spring water, it is an enviable asset. There are few fields in our village, and there are no streams at all. Most of them are reclaimed land. These fields are barren and difficult to cultivate, and they have to be washed from time to time. There is too much salt in the sea. Therefore, every family has a difficult experience. Only when the reservoir releases water in summer, and the clear water is sent to the ground through the long aqueduct and canal and then through the diversion canal, can everyone rest for a few days. When the reservoir was clear, the village was full of joy, and the happy atmosphere was still fresh in my memory. Baidu's word "fight" actually exposed a poem by Weng Fang, "Happy Rain", "The waterwheel doesn't fight, and every family buys wine songs." If it rains, irrigation can be avoided, and farmers are also happy. It's the same at all times and in all countries.

Wang Zhen, the inventor of China Yuan Dynasty, has no biography in the official history. His deeds can be found in the chronicles of Anhui and Jiangxi. According to legend, there was a county magistrate named Wang Zhen in the Yuan Dynasty. When I was young, I was the county magistrate of Jingde County, Xuanzhou. He found that since ancient times, farmers have been relying on the weather to make agriculture stagnate, so they actively advocated agriculture and mulberry, and made a lot of contributions to agriculture in China.
Wang Zhen's first contribution to agriculture was the invention of green manure. The method is to rot a lot of grass and then apply it to the ground as fertilizer. Seeing that the crops in Wang Zhen are flourishing, farmers have followed suit. Then, Wang Zhen invented another great agricultural tool: water mill. This is an invention that uses hydraulic impact waterwheel to generate electricity and lead water from low to high. Soon after, Wang Zhen improved the water mill into an agricultural machinery-water wheel, which can fetch water and grind rice, flour and spring water. For hundreds of years, this invention has liberated people from heavy manual labor and greatly reduced the workload of farmers.
Another important invention of Wang Zhen is that after Bi Sheng's clay type edition, he created wood type printing, also stipulated the specifications of wood type, and invented the wheel typesetting frame. Finally, the production method of wooden movable type, the technological process of typesetting and printing, etc. It was written into the article "Making Movable Type Printing Calligraphy" and attached to his book "Agricultural Books". This is an important historical book that records the printing in history.
Nong Shu is an agricultural work written by Wang Zhen in 17 years. Book140,000 words, 37 volumes and 306 illustrations. There are more than 100 kinds of mechanics introduced in the book.
Wang Zhen not only made an extremely important contribution in the history of agricultural science, but also made brilliant achievements in the history of machinery and printing. A versatile scientist like him is a valuable talent in the history of science in China.
