Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and in particular to a method for remediating soil before sowing continuous cropping crops. Background Art

[0002] In the process of vegetable cultivation, continuous cropping has become a key factor affecting vegetable growth. In fact, continuous cropping refers to the phenomenon that the same crop is continuously cultivated on the same land, and its growth, development, and diseases and insect pests are serious. Under continuous cropping conditions, the plant's absorption capacity is affected, growth and development are slow, the plants are weak, and the flowering and fruiting rate is reduced, especially for melon and fruit vegetables. Planting resistance is reduced, and element deficiency is prone to occur; continuous cropping will cause the occurrence of diseases and insect pests to intensify, such as wilt disease, red spider mites, etc., and the disease resistance of crops will be reduced and difficult to cure. At the same time, due to the increased resistance to diseases and insects, once a large area of ​​diseases is difficult to control, the cause of the above continuous cropping problems is soil degradation; and the deterioration of the microbial environment, etc., the current soil remediation methods are mostly direct spraying of remediation agents, and the remediation method is relatively single, resulting in poor remediation effects. For this reason, we propose a soil remediation method before sowing continuous crops. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a method for soil remediation before sowing of continuous cropping crops, which can effectively improve soil conditions so that the soil can once again meet the soil environment required for the growth of continuous cropping crops, increase the yield of continuous cropping crops, reduce the occurrence of diseases and pests, and effectively solve the problems in the background technology.
