What are the precautions for growing mustard greens? Master the key growing points in one article

Mustard greens are a rather unique vegetable in China. Both the root and the leaves can be used, and in many places people call it kohlrabi. It can be stir-fried directly or used for pickling, and it can be grown in all parts of China. As people's living standards continue to rise, mustard greens have become one of the vegetables everyone loves very much. Market demand is relatively large, and the growing area is gradually increasing. So let us take a look below at what issues we need to pay attention to when growing mustard greens.

1. Time

The sowing time of mustard greens is mainly related to the growing region. Generally, it can be grown in spring and autumn, but autumn sowing is still the main approach. In places such as the long Huang-Huai region of China, sowing can basically begin in July each year. The latest sowing time cannot be later than October. Of course, the best sowing time is August. Mustard greens sown in August have the best yield and quality, so we need to choose a suitable time for growing according to the specific situation.

2. Temperature

Mustard greens are a cool-loving vegetable, suitable for growing at temperatures of 15 to 25 degrees, so the issue of temperature also needs to be considered when choosing the growing time. Generally, places where the annual average temperature can reach around 15 degrees are most suitable for growing mustard greens. At the same time, we must note that the growing temperature cannot be higher than 30 degrees, otherwise it will affect the quality of the mustard greens, and in severe cases it will cause the plants to be scorched to death by the sun.

3. Germination

Before sowing, we need to treat the mustard green seeds and promote germination. Generally, mustard green seeds are in a dormant state, so we need to first sun-dry the seeds, then place the seeds in an environment with a temperature of 3 to 4 degrees to promote germination. Usually, sowing can be carried out after 2 to 3 days.

4. Sowing

Mustard greens are generally sown by broadcasting, but when sowing, note that the seeds must be spread evenly. Second, after spreading the seeds, press the seeds into the soil so they are not carried away by wind or rain. At the same time, this also helps the seeds absorb water and promotes the speed of sprouting. Finally, if you are not afraid of the trouble, you can also use drilling, which can reduce a certain amount of labor for later field management.

5. Density

Because broadcasting is generally used for sowing, the density is not controlled and needs to be adjusted later. So when the mustard green seedlings grow to a certain extent, we thin and fill in the seedlings. At the same time, the surplus mustard green seedlings can be transplanted. Usually, it is necessary to ensure at least about 40,000 plants per mu. Generally, final planting is carried out at a row spacing of 50 to 55 cm and a plant spacing of 40 to 50 cm, so as not to affect the normal growth of mustard greens. Among this, the density can be reasonably adjusted according to the fertility of the soil.

6. Water and fertilizer

Mustard greens are a relatively moisture-loving vegetable. If there is no rainfall after sowing, watering once or twice is needed to ensure the emergence rate of mustard greens. Second, after emergence, water in time, then water after final planting, and finally water scientifically according to the dryness of the field soil, ensuring that the field humidity is at least above 70 percent. When preparing the land, we should apply base fertilizer well according to the amount required per mu of 2,000 jin of organic fertilizer and 100 jin of compound fertilizer, then carry out the first topdressing after final planting, mainly irrigating with nitrogen fertilizer as the main type. Because the growth of mustard greens needs a large amount of nutrients, at least four or five topdressings are needed throughout its entire growth period. The specific fertilization situation needs to be scientifically applied according to the growth of the mustard greens.
