Shallow water and deep water continuous cropping cultivation method for cress

Abstract

The invention belongs to the technical field of vegetable cultivation, and relates to a cress cultivation method, in particular to a shallow water and deep water continuous cropping cultivation method for the cress. The shallow water and deep water continuous cropping cultivation method comprises shallow water cress cultivation and deep water cress cultivation, wherein the shallow water cress cultivation refers to that seed metering starts in the middle of May, the cress comes into the market in July and harvest ends in the beginning of September; and the deep water cress cultivation refers to that plantation is performed in the middle and last days of September, and batch harvest is performed from the last days of November to March of the next year. Shallow water and deep water cress cultivation comprises processes including variety selection, soil preparation and fertilization, shed building, sun shading and temperature control, seed metering in good time, accelerating germination seed metering, field management, pest control, harvest and the like. According to the shallow water and deep water continuous cropping cultivation method for the cress, the planting mode of whole-year production and whole-year supply of the cress is achieved, the cress comes into the market in eight months of a year, high benefit higher than 15 Yuan / m<2> is achieved for cress planting, and the problem of vegetable lack in hot summer is solved simultaneously.
