Description

technical field [0001] The invention relates to a weeding fertilizer for rape fields. Background technique [0002] Rapeseed cultivation is generally carried out on the previous stubble, such as rice stubble, which is generally uncultivated or shallow cultivated land, which is inconvenient for fertilization, and weeds occur early, occur in large quantities, and cause serious damage. In order to solve the practical problems of weeding in fertile fields and strong seedlings and healthy plants in the process of rapeseed cultivation, the inventors combined herbicides with systemic conduction type pre-emergence soil treatment and compound fertilizers to develop a collection of fertile fields and weeding in rapeseed fields. All-in-one special fertilizer for rapeseed weeding. Before the rapeseed is transplanted, the fertilizer is evenly spread on the rice stubble, and then the rapeseed is transplanted after being shallowly screwed into the soil, which not only solves the problem o...
