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

example 1

[0020] First, use a puncher to punch 200 holes in the compacted soil to be repaired in sequence, the hole depth is 0.5m, and the hole diameter is 10cm; then, 90L of water is introduced into the compacted soil to be repaired to make it wet. Soften the soil; then get 800 just-born little earthworms and place them in a sterilized incubator with a length of 80 cm, a width of 60 cm, and a height of 15 cm. The temperature is controlled at 6°C and the humidity is controlled at 60%. 5cm of sludge from the secondary sedimentation tank of the urban domestic sewage treatment plant to cover the body of the earthworms until the earthworms have completely eaten the feces and transformed them into vermicompost, and then the earthworms are separated, and the earthworm feces are evenly spread in the above-mentioned holes ; Subsequently, 700 black soldier fly young pupae are placed in an incubator with 50kg of livestock and poultry manure, the temperature in the control room is 25°C, and the foo...

[0023] First, use a puncher to punch 230 holes in the compacted soil to be repaired in sequence, with a hole depth of 0.7m and a hole diameter of 12cm; then, introduce 100L of water into the compacted soil to be repaired to make it moist. Soften the soil; then get 900 newly born little earthworms and place them in a sterilized incubator with a length of 100cm, a width of 85cm and a height of 30cm. The temperature is controlled at 25°C and the humidity is controlled at 65%. 7cm of sludge from the secondary settling tank of the urban domestic sewage treatment plant to cover the body of the earthworms until the earthworms have completely eaten the feces and transformed them into vermicompost. ; Subsequently, 800 black soldier fly larvae were placed in an incubator with 70kg of livestock and poultry manure, the temperature in the control room was 30°C, and the food humidity was kept at 70%, and livestock and poultry manure was added once every other day to make it suck Finally, it...

[0026]First, use a puncher to punch 250 holes in the compacted soil to be repaired in sequence, the hole depth is 0.8m, and the hole diameter is 15cm; then, introduce 120L of water into the compacted soil to be repaired to make it wet. Soften the soil; then get 1000 just-born small earthworms and place them in a sterilized incubator with a length of 120cm, a width of 90cm, and a height of 35cm. The temperature is controlled at 30°C and the humidity is controlled at 70%. 8cm of sludge from the secondary sedimentation tank of the urban domestic sewage treatment plant to cover the body of the earthworms until the earthworms have completely eaten the feces and transformed them into vermicompost. Subsequently, 900 black soldier fly pupae are placed in an incubator with 100kg of livestock and poultry manure, the temperature in the control room is 35°C, and the food humidity is kept at 80%, and the livestock and poultry manure is added once every other day to make it suck After 5 day...

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...
