Problems solved by technology

In production, transplanted rapeseed is generally disinfected with cyanazifazole seedbed combined with chlorothalonil to irrigate the roots in the field, but the control cost per mu is more than 200 yuan, which is difficult for farmers to accept, and there is still no effective control method for direct seeding rapeseed

Abstract

The invention relates to a special-purpose rape fertilizer for preventing clubroots. The special-purpose rape fertilizer for preventing the clubroots is characterized by comprising urea, diammonium hydrogen phosphate, potassium chloride, ammonium chloride, coating lime nitrogen and boron particles, wherein the raw materials with percentage by weight comprise the urea 22.5-27.5%, the diammonium hydrogen phosphate 15.0-20.0%, the potassium chloride 18.0-22.0%, the coating lime nitrogen 28.0-33.0% and the boron particles 0.7-0.9%. The special-purpose rape fertilizer for preventing the clubroots can improve soil environment, reduces rape clubroots to happen, improves yield of rapes, and is low in production cost and convenient to apply.

Description

technical field [0001] The invention relates to a special fertilizer for rape for preventing and treating clubroot. Background technique [0002] Clubroot is a ubiquitous soil-borne disease. The pathogen (Plustridium brassicae) can survive in the soil for more than 10 years. It is mainly transmitted through fungus-carrying soil, seeds and irrigation, and exclusively infects Brassicaceae plants. . In the past ten years, due to the large-scale promotion of Brassica napus, climate warming, soil nutrient imbalance, and aggravated acidification, coupled with the north-south transfer of commercial seeds and frequent cross-regional mechanical operations, Sichuan, Hubei, Hunan and other provinces in my country have Clubroot in the city shows a trend of expanding year by year, generally reducing production by more than 15%, and severely affected fields may even fail to harvest. In production, transplanted rapeseed is generally sterilized with cyazofamid seedbed combined with chlorot...
