Grassland degraded soil conditioner and an application method thereof

Abstract

The invention belongs to the technical field of ecological environment and discloses a grassland degraded soil conditioner and an application method thereof. The grassland degraded soil conditioner isprepared from the following components by mass: 2 kg of a microbial water-retaining agent, 47 kg of biological carbon, 100 kg of organic fertilizer and 1 kg of AM fungi. The application method comprises the following steps: 2 kg of the microbial water retention agent, 47 kg of biological carbon, 100 kg of the organic fertilizer and 1 kg of the AM fungi are weighed respectively and mixed uniformlyfor standby application; the mixed fertilizer is uniformly applied to the degraded grassland, irrigation is performed or sprinkling irrigation is performed once after ploughing, and high-quality herbage is sown; topdressing is performed again after the herbage grows to the seedling stage. Aiming at two important influence factors restricting productivity of grassland soil, the invention providesone novel grassland degraded soil conditioner suitable for grassland restoration.

Description

technical field [0001] The invention belongs to the technical field of ecological environment, and in particular relates to a grassland degraded soil improver and an application method. Background technique [0002] A series of ecological problems such as grassland degradation, alkalization and desertification exist to varying degrees in the vast majority of grasslands in the country, which are the ecological consequences of human beings' unreasonable use of grasslands. One of the signs of grassland degradation is the decline in grass yield. According to surveys, the pasture production of various types of grasslands in the country generally decreased by 30-50% compared with the 1950s and 1960s; the second sign of grassland degradation is the change in the quality of pastures, the reduction of high-quality edible pastures, and the increase of poisonous weeds and weeds. The use value of pastures has declined. my country is one of the countries that suffer the most from deser...

AI Technical Summary

Problems solved by technology

[0004] In summary, the existing problems in the prior art are: the application of chemical fertilizers can easily lead to soil compaction, and the simple application of organic fertilizers has the problem of slow decomposing and forming soil.

[0005] Among the existing amendments for treating grassland degraded soil, there is no combination of soil water content and soil beneficial microbial population to improve grassland degradation
