There are many ways to utilize green manure in organic tea gardens, among which the following are the main ones. First, it is used as livestock feed. Many tea garden green manure stems, leaves and pods can be used as livestock feed and have high nutritional value. After the green manure is digested and absorbed by the animal's gastrointestinal tract, the green manure is harmlessly treated through livestock manure and applied to the tea garden as organic fertilizer. It can be used as base fertilizer. In this way, the organisms in green manure can be fully utilized, which is an important measure for organic agriculture and the best way to utilize green manure in organic tea gardens.
Second, it is used as biogas fermentation material. Tea garden green manure has high organic matter content and is a good material for biogas fermentation. Put green manure and livestock and poultry manure together in a biogas tank for fermentation. The biogas produced can be used for tea frying and lighting. The waste residue and biogas liquid have high nitrogen content and strong quick effect. They can be used as top dressing in tea gardens, which can also be fully utilized. The bioenergy in green manure serves organic tea production and is also the best way to utilize green manure in organic tea gardens. Third, it is used as soil cover for tea gardens. Soil mulching is an extremely important agricultural technique measure for organic tea production and has many benefits. However, due to the limitation of mulching grass sources, its promotion has been affected. Green manure is the best soil covering grass available on site. Summer green manure sown in spring can be used as mulching grass during droughts in summer and autumn. After being pulled up, it can be spread directly between the rows and buried in the soil as fertilizer during autumn and winter plowing. Autumn plays the role of drought resistance and seedling protection, and autumn and winter play the role of deep plowing combined with the application of base fertilizer. Winter green manure sown in autumn can also be used as soil covering grass in spring and summer. It can prevent erosion, preserve moisture, and cool down. It can be buried in the soil as fertilizer when the tea garden is shallowly cultivated the following year. It kills two birds with one stone. This is also a better way to utilize green manure in organic tea gardens. . Fourth, directly bury it as fertilizer. For tea garden green manure, you can directly bury the green manure between the rows and use it as fertilizer. When sowing winter green manure in autumn, wait until the green manure has flowers and pods in May. Pull out the plants and then dig ditches between the rows for spring fertilizer application. Sow summer green manure in spring and wait for green manure in August to September. When the flowers grow and the pods appear, dig ditches to apply fertilizers in summer and autumn. Directly burying green manure with green manure can increase soil moisture content and has a good effect. However, when directly burying green manure, you must prevent the green manure from rotting and fermenting and "burning the roots". Therefore, when burying green manure, do not get too close to the tea roots. It is best to bury it between the rows. Fifth, it is used for composting and composting. Dig several pits of different sizes on the edge of the tea garden, put various green manures, local weeds, litter and other organic matter into the pits, as well as some manure, sea manure, and pond mud. After a period of stacking and digging, To make it effective, it can be used as base fertilizer or top dressing during the tea garden fertilization season.
