Chinese kale is a variant of cabbage. It is an annual herb. It is not only a famous vegetable in China, but also an export dish sold in Hong Kong, Macao and Southeast Asia. It has become more and more popular in Beijing, Shanghai and other big cities in recent years. Let's take a look at the cultivation technology of kale!
First, seedling sowing
Canola can be transplanted by live or seedling. When the seedlings are planted, the sandy loam or loam should be selected to be loose and fertile, and convenient for irrigation and drainage. The soil should be kept moist during the planting period, and some thin fertilizers can be applied to promote the growth of the seedlings. Appropriate seeding, pay attention to the seedlings, avoid too dense and cause the seedlings to be thin.
Second, field management
The growth of Chinese kale is slow in the early stage, and weeds are easy to grow between the lines. Therefore, it is necessary to carry out cultivating and weeding in time. In daily management, watering should be timely according to temperature and humidity. During the formation and harvesting period of vegetable moss, it is necessary to increase the number of watering and keep the soil moist.
Base fertilizer and topdressing are both heavy, and topdressing is applied with water. Generally, after 3 to 4 days of slow seedling, a small amount of nitrogen fertilizer or chicken manure should be applied. When the bud is bolted, appropriate quick-acting fertilizer or human excrement should be applied. After the main moss is harvested, it is necessary to promote the growth of the side moss, and the fertilizer should be applied 2 to 3 times.
Third, pest control
The diseases and insect pests of kale are still relatively small compared with other vegetables, but black rot is prone to occur in high temperature and high humidity weather, which can lead to plant death and timely prevention and treatment.
Control method:
(1) Avoid continuous cropping with cruciferous vegetables;
(2) If the infected plants are found in the field, they should be removed in time;
(3) Once the disease is found, it can be sprayed immediately with chlorothalonil and carbendazim.
Fourth, timely harvest
The pickling time of the kale is generally selected on a sunny morning. When the main flower is harvested, it is cut obliquely from the 6 leaves at the base of the plant. The harvest of the lateral calyx was cut at the base of the base 2. Note that the incision must be tilted to avoid stagnant water.
The kale is rich in nutrients, tender flowers and young leaves. It is rich in nutrients, crisp and tender, and has a good flavor. It is very popular among consumers. The market has a very promising future, and it is recommended for a planting project.
