talks about green manure. Many agricultural people actually don’t understand it very well. Today, Changmu will tell you about green manure.
What is green manure? Any green plant used as fertilizer is called green manure. my country is the earliest country to utilize green manure. Green manure is one of the most widely used organic fertilizers in my country's agricultural and forestry production.
green manure in agricultural and forestry production is reflected in the following aspects:
(1) Developing green manure is an important way to solve the shortage of organic fertilizer sources. The green manure yield is large, with a fresh weight of generally tens of thousands of kg per hectare, and contains more organic matter and nutrient elements.
(2) The green fertilizer tissue is tender, the C/N ratio is small, the decomposition is fast, and the fertilizer effect is significant.
(3) Some green manure plants have strong absorption capacity and can absorb and utilize deep soil nutrients and less soluble nutrients, which can improve the structure and tillage of the soil.
(4) Green manure can improve soil physical and chemical properties and improve soil fertility Green manure can improve the quantity of soil organic matter and update its quality after turning over pressure, and improve soil physical and chemical properties. Research shows that turning over pressure green manure can increase the amount of soil cation exchange, improve the properties of soil organic and inorganic complexes, and is conducive to the formation of water-stable particle structure, making the relationship between soil water, fertilizer, gas and heat more coordinated, thereby improving soil fertility.
(5) Green manure can cover the ground, consolidate sand and slope protection, prevent soil erosion, and improve the ecological environment. In arid and semi-arid areas, the lush stems and leaves of green manure can increase surface coverage and prevent water from evaporating too quickly, thereby inhibiting soil salt reflux.
planting green manure has obvious effects on conserving water sources and preventing soil erosion According to the test of Inner Mongolia Soil and Water Conservation Station, planting plants reduces surface runoff by 61% compared to open ground and reduces land erosion by 90%.
test proves that the application of green fertilizer purple-sized locust has a significant impact on the growth of poplar trees, and has obvious effects on increasing the growth of tree height, breast diameter and material volume. It is also proved that the fertilizer effect of green fertilizer is second only to nitrogen fertilizer, but is higher than phosphorus fertilizer and potassium fertilizer. The best ratio is that nitrogen, phosphorus, potassium fertilizer and green fertilizer are matched with green fertilizer. The interplantation of green fertilizer can improve soil fertility and promote forest growth, but attention should be paid to avoid competing with young forests for nutrients and moisture during the growth period of green fertilizer.
or above are related contents of green manure. I hope that the content posted by Changmu can be of some help to the majority of agricultural people.
