A method for repairing soil compaction in arable land

Abstract

The invention relates to a repair method for cultivated land soil compaction, which belongs to the technical field of soil repair. The present invention first makes holes on the soil surface to soak and soften the soil after water diversion, then spreads earthworm manure, black soldier fly manure, water floating lotus roots, and straw ash in the holes in order, and finally Water diversion is used to irrigate the farmland, so that the roots of the water lilies grow new water lilies, and then the soil is turned up again, so that the deep soil in the field is turned up, and the shallow water lilies are covered. Examples prove that the method of the present invention is simple, does not add any chemical components, does not cause any harm to the environment and soil, and not only reduces the risk of soil erosion, solves the problem of soil compaction, but also increases the annual output of crops More than 92%.

Description

technical field [0001] The invention relates to a repair method for cultivated land soil compaction, which belongs to the technical field of soil repair. Background technique [0002] As countries around the world pay more and more attention to the sustainable development of agriculture, higher requirements are put forward for the sustainability of soil production capacity. Especially in my country with a large population, little arable land, and the severe situation of food security, how to ensure the sustainable development of soil is particularly important. Soil compaction is one of the important manifestations of soil degradation, especially the subsurface soil compaction. Now the plant roots grow underground. In the middle and late stages of plant growth, if there is little rainfall and high evaporation, soil compaction seriously affects the water absorption of plants. Drought can limit plant growth and yield development. [0003] At present, to solve the problem of s...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: the current soil compaction problem makes the soil degrade, and encounters the situation of little rainfall or large evaporation, which seriously affects the absorption of water by plants, makes the plants dry up and dies, and affects the yield, and the commonly used deep tillage method is in operation. The time cost in the process is relatively high, and the effect is relatively short-lived. Even if the problem of soil compaction is alleviated, it still destroys the surface covering developed by years of no-tillage management, and increases the risks of soil erosion and topsoil compaction. It provides a cultivated land soil The hardening restoration method, the method first makes holes on the soil surface to soak and soften the soil after water diversion, and then spreads earthworm feces, black soldier fly feces, water floating lotus roots, Straw ash, and finally divert water to irrigate the farmland again, so that the roots of the water lettuce grow new water lettuce, and then turn the soil again, turn up the deep soil in the field, and cover the shallow water lettuce, thus solving the problem of soil compaction in the farmland The problem of globalization has increased the yield of crops by more than 92% per year
