Embodiment

[0032] On April 28, 2018, one mu of fruit mulberry (Taiwan Daguo) was planted using the new technology of soil ecological restoration, and a total of 74 plants were planted with a row spacing of 3 meters x 3 meters. Its fruit seedlings are young seedlings that survived cuttings in the previous year. In the first three months, the daily growth rate reached 1-2 cm. After three months, the maximum plant height reached 1.8 meters, the crown diameter was 1 meter, and the growth potential was extremely vigorous. Compared with the control of the same variety in conventional planting, the biomass increased by more than one-third. In early April 2019, mulberries were harvested, and the yield per mu reached 375 kg, while the yield per mu of the control was only 201 kg, and the quality was significantly better than that of the control, with a very significant difference. Compared with conventional planting, 25 more plants are used (60 yuan / plant), totaling 1,500 yuan, and multi-purpose ...

Abstract

The invention discloses a soil ecological restoration method. By building up soil on the land to be repaired, the surrounding soil is built into a mound along the center, and crops are selected to be planted in the center of the piled up mound, and the open space to be removed from the cultivated layer grows. When there are a lot of weeds, weeding is carried out. After six months, the surrounding matured soil is dug up to the mound to make the mound continue to expand, and the next layer of raw soil is exposed to contact with air and sunlight for further maturation. The method of the invention enables the soil to be continuously repaired and matured through the comprehensive action of animals, plants, microorganisms, air, sunlight, water, etc., thereby producing high-quality, ecological, and safe green food while effectively protecting the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of soil restoration and utilization, and in particular relates to a soil ecological restoration method. Background technique [0002] Pesticides and chemical fertilizers are the material guarantee for the development of modern agriculture. Pesticides enter the soil through various channels, which makes the pollution of the soil environment more and more serious. Although the purification of the soil itself, such as: volatilization, diffusion, dilution, adsorption, degradation, etc., can reduce the pollution of pesticides in the soil, but if the amount and speed of pesticides entering the soil exceed the self-purification ability of the soil, that is Exceeding the environmental capacity of the soil will eventually lead to pesticide pollution of the soil. Modern chemical agriculture, which uses chemical fertilizers, pesticides, hormones, herbicides, genetically modified substances and other technologies, has...
