Problems solved by technology

Before the seeds germinate and take root, the soil protection fiber cotton net can only play a role in rainfall splash erosion, and has no effect on soil surface runoff erosion, especially under heavy rain or rainstorm conditions, if the fiber net is not fixed

Abstract

The invention provides a soil erosion resistance control method which comprises following operation steps: (1) bacterial manure serum is prepared and uniformly sprayed on the soil surface, and the spraying thickness is less than or equal to 5mm; (2) protective serum is prepared and uniformly sprayed on the soil surface treated in step (1), and the spraying thickness is less than or equal to 3mm; (3) straw cellulose hydrolyzate is prepared; (4) after step (2) is implemented for 5 to 7 days, the soil is mechanically turned over, and the straw cellulose hydrolyzate prepared in step (3) is uniformly sprayed into the soil; and (5) the protective serum prepared in the step (2) is uniformly sprayed onto the soil surface treated in step (4), and the oil is mechanically turned over and leveled again after 3 to 5 days of implementation. The soil erosion resistance control method has the advantages of simple operation, reasonable integrated cost, continuous mechanical implementation and capability of effectively improving the granular structure of the soil, increasing the content of soil aggregates, improving the anti-erosion capability of the soil and preventing water and soil loss, and is mainly used to improve the anti-erosion capability of the soil.

Description

technical field [0001] The invention relates to a soil control method, in particular to a soil erosion resistance control method applied to soil improvement and control in the fields of agriculture, forestry, gardens, ecological restoration and the like. Background technique [0002] Soil is the basic resource of agricultural and natural ecosystems, and is the material base for the production of food, vegetables, forest trees, ground cover, lawn, etc. However, due to the irrational development and utilization of soil by human beings, the soil is increasingly desertified, desertified and salinized, and the continuous degradation of soil texture has caused serious water and soil erosion, resulting in a lack of available land resources in our country. Soil loss has become an important issue in our country. Containment factor of sustainable development of agriculture, forestry and ecological construction. The traditional soil anti-erosion method is mainly to cover some material...
