The role of green manure in agricultural production

November 30, 2018

The role of green manure in agricultural production is mainly summarized as follows:
1. It can provide a large amount of high-quality organic fertilizer to promote the increase of crops. Green manure can be widely planted, rich in nutrients, high yield of fresh grass, and significant yield increase effect.
2. Increase soil nutrients and improve soil by fertilizing. Green manure fresh grass contains 10%-15% of organic matter, nitrogen content 0.3%-0.6%, calculated by 1000kg fresh grass, can provide organic matter 120-195 kg, pure nitrogen 4-7 kg. This has a certain effect on increasing soil nutrients and improving soil.
3. Collect lost nutrients. Green manure can collect the fertilizer lost from farmland, transfer it to farmland nutrient circulation, and improve nutrient utilization.
4, keep water and soil, let the wind and sand. Green manure crops are rich in stems and leaves, covering the field, which can reduce the loss of water, soil and fertilizer, and inhibit the growth of weeds in the field. Green manure is planted in sloping land, sandy land and mountainous areas, which can reduce the rain from brushing, and play the role of sand fixation and soil protection.
5, green manure is still a good feed. Green manure crops are generally rich in protein, fat, sugar and vitamins, and the stems and leaves are soft. They can be used as silage for silage, or as dry feed for livestock and poultry. In addition, some green fertilizers such as Ziyunying are excellent sources of honey and can also promote the development of beekeeping.
