Multi-cropping planting method for Brassica campestris

Abstract

The invention discloses a multi-cropping planting method for Brassica campestris. The method comprises the following steps: (1) carrying out land preparation; (2) carrying out crop arrangement; (3) carrying out seed sowing; (4) carrying out fertilizer and water management; (5) carrying out disease and insect pest control; and (6) carrying out vegetable harvesting. According to the method, an applied special fertilizer for the Brassica campestris has a very good sustained-release effect, and the nutritional requirements of the Brassica campestris during multi-cropping planting can be guaranteed by applying the fertilizer twice every year, so that the substance utilization ratio is increased, and manual operation and fertilizer cost are reduced; and sprayed special drugs for disease and insect pest control have a very good control effect on insect pests such as Phyllotreta striolata, flies, aphides and thrips and diseases such as downy mildew, anthrax, soft rot and virus disease of the Brassica campestris, and drug residue cannot be caused, so that the quality of vegetables is guaranteed, the sustained supply of the vegetables is guaranteed by the reasonable multi-cropping planting, land resources are sufficiently utilized, and the yield is increased. Under the integrated action of all stages, finally cultivated Brassica campestris is high in nutritive value, good in product appearance and high in yield and is free of drug residue.
