Cultivation techniques of Chinese cabbage

Rabdosia angustifolia is a perennial herb of crassulaceae, and it is a common ornamental plant, but in fact, it has high medicinal value. Cabbage plays a certain role in some injuries and heart disease. Cabbage has a certain wild area in all parts of our country, but with the continuous picking, the number of wild cabbage is gradually insufficient. Therefore, artificial cultivation has also begun, so how to cultivate cabbage? Let's take a look at it with the editor.

1. Land selection and fertilization

The adaptability of cabbage is relatively strong, the demand for soil is not very large, and can grow normally in most of the soil. However, if we want to further improve the growth of cabbage, we should choose sandy soil with strong water and fertilizer conservation. After selecting a good site, do a good job of soil preparation to prevent residual pesticides and germs, avoid affecting the growth of cabbage. And apply sufficient base fertilizer, the base fertilizer can be used mature farm manure to provide enough nutrition for the growth of cabbage. Then you can sow the seeds, pay attention to the sowing density when sowing, not too dense, otherwise it will affect the growth of each other.

2. Water management

When watering cabbage, you should pay attention to the time and dosage, observe the water content of the soil, water in time when the soil is dry, and less if it is moist. We can also determine whether it is in a state of water shortage according to the observation of the leaves, for example, when the leaves are dim, it means that they need to be watered. When watering, we should pay attention to watering the soil thoroughly, not wet and dry, so that the water does not penetrate to the roots at all. And can not pour water when wet, otherwise lead to too much water content, root respiration is blocked, so that the leaves green, serious hypoxia death.

3. Reasonable topdressing

The amount of fertilizer needed for cabbage is relatively large, so we should do a good job of topdressing in the growth, and we should give priority to more and a small amount of fertilizer to cabbage. Fertilizer usually needs to be applied once a month, and special granular fertilizer can be purchased on the market. Otherwise, farm manure and animal offal can also be used, but attention should be paid to full ripening and fermentation when using these fertilizers. And the medicine can not be applied directly, it can only be diluted. Otherwise, too high concentration and calories will burn out the roots of cabbage, resulting in blocked absorption of nutrients and even death. And in the mature period, each harvest of tender stems and leaves should be combined with a topdressing to promote the new branch growth of the plant and increase the yield.

4. Overwintering management

The vitality of cabbage is relatively strong, but also has a certain degree of cold resistance, but we should also do a good job in overwintering management of cabbage to prevent accidents. After winter, the cabbage planted in the north should do a good job of cold prevention and heat preservation, first irrigate the overwintering water, and then cover the plant with plastic film and straw to keep warm. Let the cabbage go into a dormant state to ensure that all cabbage can survive the winter successfully. If possible, additional heating equipment can be added in the greenhouse, and attention should be paid to ventilation. It lays the foundation for the growth of cabbage in the second year and makes it more robust.

The above is a brief introduction to the cultivation technology of cabbage, the planting cost of cabbage is relatively low, and the requirement of planting technology is not high. But we also need to do a good job in the management of planting, not carelessly, otherwise it is only ourselves who will suffer.
