Method for quickly improving soil aggregate content through biomass ash

Abstract

The invention discloses a method for quickly improving the soil aggregate content through biomass ash. A vegetable field with the slope smaller than 10 degrees is selected, and organic fertilizer is applied 800 kg/mu before crop sowing to serve as base fertilizer; the biomass ash is evenly applied 1200 kg/mu two days later, and then soil is ploughed with the ploughing depth of 20 cm; it is guaranteed that the soil moisture content is not smaller than 45% seven or more days, and then crops can be planted. In the method, engineering development on land is not needed; the method is easy to implement, operation is easy, raw materials are easy to get, cost is low, and the aggregate amount can be improved within a short period of time which is mainly embodied in the aspects of improving the water-stable aggregate amount, soil porosity and soil water retention capacity. By quickly improving the soil aggregate content through the biomass ash, ecological and economical benefits can be achieved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for rapidly improving soil aggregates by using biomass ash. Background technique [0002] my country is the country with the largest output of agricultural waste in the world. The agricultural residues such as straw are huge and widely distributed. However, the vast majority of agricultural waste is not used as resources, and is discarded at will or discharged into the environment, making some "resources " has become a "pollution source", which has caused a great impact on the ecological environment. In recent years, a number of power plants using agricultural waste as energy have been built in various places. Although the power generation technology of agricultural waste such as straw solves the problem of the utilization of agricultural waste resources, it also leaves power generation residue—biomass ash. [0003] With the large increase of urban population, ...

AI Technical Summary

Problems solved by technology

[0003] With the large increase of urban population, a large number of commercial vegetables are also produced. The utilization rate of vegetable land is high, the input is large, the output is large, the commodity is large, and the income is large. However, long-term predatory farming has caused great damage to the soil, resulting in poor physical and chemical properties of the soil. , the soil is easy to harden, and modern planting is highly dependent on chemical fertilizers, etc.

The surface structure of the soil has poor performance and weak stability, and it is impossible to achieve a sustained and stable increase in production and income
