Abstract

The invention relates to a method for growing Chinese kale in greenhouses. The method comprises the following steps of step S1, selecting a cultivation environment; step S2, selecting a variety, and selecting the variety suitable for planting in greenhouses in early spring during cultivation process; step S3, preparing soil, and applying fertilizers; steps S3, accelerating germination and sowing;step S4, scientifically conducting top application; step S5, managing and protecting fields; step S6, preventing and controlling diseases and pests; step S7, timely harvesting, and harvesting the Chinese kale in the greenhouses in the middle and late March, watering 1-2 days before harvesting, and conducting harvesting when a large amount of dew is on leaves in the morning. The method has the advantages that the yield per mu of the Chinese kale is increased by more than two times, and pest and disease resistance performance during the cultivation process is stronger, so that continuous spraying of pesticides can be avoided and the green health of the Chinese kale is ensured.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for growing kale in a greenhouse.
