Water-soluble fertilizer for preventing and controlling continuous cropping induced dead seedlings

Abstract

The invention relates to the technical field of water-soluble fertilizers, and concretely relates to a water-soluble fertilizer for preventing and controlling continuous cropping induced dead seedlings. The water-soluble fertilizer comprises, by weight, 20-50 parts of a high-efficiency compound microbial agent, 20-300 parts of organic matters, 300-900 parts of a medium and trace element soil conditioner, 300-450 parts of water, 75-85 parts of water-soluble coal-based ore-derived potassium humate or water-soluble coal-based ore-derived sodium humate, 10-125 parts of dipotassium hydrogen phosphate, 20-300 parts of urea, 50-500 parts of potassium tripolyphosphate, 50-500 parts of potassium formate, 5-15 parts of borax, boric acid or disodium octaborate tetrahydrate, 10-50 parts of potassium hydroxide, 10-25 parts of organic acid, 5-20 parts of EDTA complexed trace elements, 3-5 parts of AES or AEO, and 0.5-1.2 parts of xanthan gum. The water-soluble fertilizer can improve the micro-ecological environment of soil, form a beneficial microbial community and improve the soil fertility after being applied to the soil. The water-soluble fertilizer can meet the crop growth requirements, significantly enhance the stress resistance of crops, enhance the resistance and immunity of the crops to pests and diseases and improve the quality and the yield of the crops after being applied to the soil.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizers, in particular to a water-soluble fertilizer for preventing and controlling dead seedlings in heavy cropping. Background technique [0002] At present, crop dead seedlings are one of the most serious phenomena in agricultural production. When crops are planted repeatedly, the increase in soil-borne diseases will result in reduced yield or even no harvest, and the loss is quite serious. The dead seedlings of continuous cropping (heavy cropping) are analyzed from the perspective of phytopathology, which is caused by the propagation and infection of the original crop bacteria. Many of these pathogens are soil-dwelling bacteria, which can survive in the soil for a long time. When conditions permit, they can infect crops and cause crop disease; Excessive application of nitrogen fertilizers leads to lack of medium and trace elements, weak growth of crops, poor stress resistance, and ...

Problems solved by technology

[0004] In order to solve the deficiencies and defects of the prior art, the present invention provides a water-soluble fertilizer for the prevention and control of dead seedlings in heavy cropping. The present invention solves the problem of dead seedlings caused by repeated cropping when crops are planted in heavy cropping through a pest control strategy based on the soil micro-ecological system. The problem of crop production reduction or even failure caused by it; and solve the problem that the traditional method cannot fundamentally solve the problem of repeated cropping and dead seedlings
