Cabbage is also called cabbage, etc. It is a wide range of vegetables. In our country, cabbage is also one of the common growing vegetables, so let's take a look at the cultivation management technology of cabbage.
First, the cultivation time of the cabbage
Cabbage is adaptable, cold and heat-resistant. It can be cultivated in the spring, summer and autumn in our country. In other relatively high and cold areas, more than spring and summer seedlings, summer planting and autumn harvest, some cities in North China and northeast and northwest, mainly in spring and autumn.
Second, the method of raising cabbage
Cabbage cultivation is generally carried out by means of seedling transplanting. Spring cabbage is basically cultivated in early maturity, and the colder areas such as the northeast are generally cultivated in the greenhouse in the period of 2-3 months, and the seedling period is between 60 and 90 days. Autumn cabbages are raised in June-July, and the seedling period is generally 35-40 days. Summer cabbage is seeded in April-May, and the seedling period is about one month.
Third, the method of colonization of cabbage
The roots of the cabbages start to move at temperatures above 5 °C, so spring cabbages can begin to colonize when the average daily temperature reaches 6 °C. In the north, the spring is relatively dry. Generally, it is cultivated in flat sorghum. In summer, the temperature is relatively high and it is rainy. Therefore, when transplanting, it is necessary to bring as much soil as possible, and watering should be carried out after planting.
Fourth, the fertilizer management of cabbage
After the planting, the cabbage should be irrigated with water, but the soil should be ploughed in time to increase the ground temperature and promote the recovery and growth of the root system. In the rosette period, the cabbage will absorb more water and fertilizer, and the first top dressing can be carried out, and the water is fully supplied to promote the growth of the leaf ball. After the leaf ball is formed, the watering can be controlled.
Finally, the cultivation and management of cabbages is indispensable for the prevention and control of pests and diseases. It is susceptible to the damage of cabbage caterpillars in the early growth stage of cabbage, and it is best to use low-concentration and high-efficiency insecticides for prevention and treatment.
