Description
Technical Field
The invention belongs to the technical field of green manure, and particularly relates to green manure for dry land and a preparation method thereof.
Background
The green manure is a fertilizer made of green plants. Green manure is a complete biological fertilizer source. The green manure is an effective method for increasing fertilizer sources and has great effect on improving soil. The green manure can provide rich nutrients for soil. The young stems and leaves of various green manure contain rich nutrients, and once decomposed in soil, organic matters, nitrogen, phosphorus, potassium, calcium, magnesium and various trace elements in the soil can be greatly increased.
The green manure is one of the traditional important organic fertilizers in China, and the development of the green manure has the following advantages:
the method has the advantages of wide sources and large quantity. The green manure is of various types, strong in adaptability, easy to cultivate and can be planted in farmland wastelands; the yield of fresh grass is high, the yield per mu can reach 1000-2000 kg generally, and in addition, a large amount of wild green manure can be collected and utilized.
The fertilizer has high quality and good fertilizer efficiency. The green manure crops have rich organic matters, contain nutrients such as nitrogen, phosphorus, potassium and various trace elements, are quickly decomposed, have quick fertilizer effect, and can increase the yield of paddy and wheat by 9-10 kg by using the green manure containing 1 kg of nitrogen.
The soil is improved, and the water and soil erosion is prevented. The green manure contains a large amount of organic matters, so that the soil structure can be improved, and the water and fertilizer retention and fertilizer supply capacity of the soil can be improved; the green manure has flourishing stems and leaves covering the ground, and can prevent or reduce the loss of water, soil and manure.
And fourthly, the investment is small, and the cost is low. The green manure only needs a small amount of seeds and fertilizers, is planted on the spot and applied on the spot, saves manpower and transportation capacity, and has lower cost than chemical fertilizers.
And fifthly, comprehensive utilization is realized, and the benefit is great. The green manure can be used as feed for livestock to develop animal husbandry, and the animal manure can fertilize the field and promote each other; the green manure can also be used as a biogas raw material, so that part of energy is solved, and the biogas digester manure is also a good organic fertilizer and a good liquid fertilizer; some green manure such as milk vetch and the like are good honey sources and can be used for bee-keeping. Therefore, the development of green manure can promote the comprehensive development of agriculture.
The existing green manure is mostly directly planted, turned and pressed into soil, is less suitable for dry land, and has poor fertilizing effect because the dry land is hard to fully play a role.
