Simple method for remediating successive cropping obstacle soil in vegetable field by utilizing lime nitrogen

Abstract

The invention belongs to the technical field of soil sterilization, and discloses a simple method for remediating successive cropping obstacle soil in a vegetable field by utilizing lime nitrogen. Themethod comprises the steps of broadcasting or furrow application by adopting 60-100 kg / 667 m2 of lime nitrogen particles, an organic fertilizer and a composite fertilizer as a base fertilizer, rotarytillage, subsoiling, water supplementing and film mulching. The method has the advantages that the effects of sterilizing and improving soil are achieved, soil-borne diseases of multiple vegetables can be effectively prevented, soil insects can be effectively prevented and killed, and root-knot nematodes can be effectively killed; decomposition of the organic fertilizer can be promoted, a slow-released nitrogenous fertilizer in soil can be increased, in addition, calcium required by vegetables can be supplemented, and therefore the quality of vegetables is improved; soil is improved, the environmental protection effect is achieved, acidification of soil is effectively prevented, long-time applying of the lime nitrogen can effectively remediate the successive cropping obstacle soil in thevegetable field, the content of organic matters is improved, the lime nitrogen is beneficial for microflora, the soil pH value can be increased, and the lime nitrogen is beneficial for the sustainableproductbility of soil.

Description

technical field [0001] The invention belongs to the technical field of soil sterilization, and in particular relates to a simple method for using lime nitrogen to repair the soil obstructed by continuous cropping in vegetable fields. Background technique [0002] The existing soil sterilization method is to cover the whole piece of soil with the shed film and then uplift, the soil sterilization effect is not complete, the operation is complicated, and the cost is high. [0003] To sum up, the problems in the prior art are: the existing soil sterilization effect is not obvious, the operation is complicated, and the cost is high. Contents of the invention [0004] Aiming at the problems existing in the prior art, the invention provides a simple method for using lime nitrogen to repair the soil obstructed by continuous cropping in vegetable fields. [0005] The present invention is achieved in this way, a simple method of using lime nitrogen to repair the soil of continuous ...
