Cultivation techniques of Brassica campestris

Castanopsis thunbergii is a special vegetable in Anhui Province, which belongs to a variety of Chinese cabbage. It is called Xiancai because the plant collapses on the ground. Now it is mainly distributed in the south of China, where the yield is high, the taste is good, and the growth is sustainable. Is a relatively good vegetable, but also gradually introduced into other provinces. So how to grow fallen vegetables? Today, the editor has brought you the cultivation techniques of fallen vegetables, let's take a look at it!

1. Sowing and raising seedlings

The main planting method of fallen vegetables is seedling transplanting, and the soft, deep and fertile soil is selected as the seedling bed before raising seedlings. Then ploughed deeply, applied sufficient fertilizer, and ploughed the soil. After digging the seedling hole, sow the seed evenly and control the sowing density well. After sowing, cover fine soil, properly water, do a good shading measures to promote seed germination and emergence. As long as it is properly managed, the seedlings will emerge in about 3 days, do a good job of inter-seedling work after emergence, cultivate strong seedlings, and transplant when the seedlings grow about 6 true leaves.

2. Timely planting

As before seedling cultivation, soil preparation should be done about a week before planting, disinfect in time, improve the soil environment, and prevent residual herbicides and bacteria from threatening the growth of fallen vegetables. Soil preparation should be carried out with the application of base fertilizer, and the fertilizer should be controlled according to the specification of 2400kg/ mu, and the fully mature farm manure can be used in the base fertilizer. When planting, the main planting density should not be too dense to prevent each other from blocking each other after growing up, affecting light absorption and inhibiting growth. After planting, it is necessary to irrigate enough fixed root water and topdressing in time to improve the survival rate of planting.

3. Fertilizer and water management

Fertilizer and water management is an indispensable management work in the cultivation of fallen vegetables, and it is the key to ensure the normal growth and increase the yield of fallen vegetables. After planting and pouring enough fixed root water, the seedlings were watered properly according to the changes of soil water content and weather to promote the slow seedling. After slowing down the seedlings, farm manure or urea should be applied every other week to control the dosage to prevent excessive concentration and burn out the seedlings. Keep the soil in a moist state, promote water absorption and improve the growth ability of leaves. When the temperature is low in winter, the growth rate of fallen vegetables decreases, so topdressing should be reduced. When the temperature gradually rises in spring, topdressing should be applied immediately to improve the nutrient absorption of fallen vegetables.

4. Pest control

Pest control is very important in the whole growth period of fallen vegetables. We need to understand what common diseases and insect pests there are and do a good job of prevention. Prepare agents for the control of various diseases and insect pests to avoid emergencies. For example, virus diseases can use virus An agents, and aphids are also the main cause of the virus, so we also need to do a good job in aphid prevention and control. Often observe the growth of collapsed vegetables, to achieve early detection and early treatment, the spread of some diseases is very fast, untimely treatment may lead to all infections.

The above is a brief introduction to the cultivation techniques of fallen vegetables, the growth cycle is relatively short, generally 1-2 months after planting can be harvested on the market. However, when we harvest, we still have to determine the specific harvest time according to various factors such as variety, weather and market, so as to ensure the maximum planting benefit. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
