What are the main points of fertilization methods for root mustard?

Root mustard, which is what we call pimple vegetable and kohlrabi, is a kind of vegetable with rich nutritional value. Because it is rich in fiber, it can effectively relieve constipation. In addition, it can also play a heat-clearing, anti-inflammatory, antibacterial, detoxification effect. Now let's take a look at the main points of fertilization methods for root mustard.

What are the main points of fertilization methods for root mustard?

In addition to the base fertilizer in the soil, the root shepherd's purse also needs additional topdressing, which is generally needed for about three times during its growth period. The first time is in the root shepherd's purse emergence after the application of relatively thin human and animal urine the latter feces, so that its leaves can grow stout. The second topdressing is when shepherd's purse leaves and fleshy roots grow rapidly, apply slightly thicker human and animal feces mixed with urea. If it grows well during this period, there is no need for extra fertilizer. The third topdressing is mainly based on its growth, and if the growth is weak, it is necessary to apply human and animal manure.

Generally speaking, it is to use organic fertilizer as base fertilizer, and then add nitrogen fertilizer, potash fertilizer, phosphate fertilizer and so on, so that the commodity value of root shepherd's purse is high, and growers get more benefits.

2. Planting techniques of root mustard

1. Planting time

Planting root shepherd's purse is to choose autumn sowing, here there is no distinction between the south and the north. The temperature drops rapidly in autumn, and the sowing time can be slightly earlier in winter where the temperature is very low. In areas where temperatures drop slowly in winter, sowing can be delayed. The mastery of sowing time is very critical, if it is too early, it is easy to appear early bolting, and if sowing too late, the yield and quality will be reduced due to the lack of nutrients in the previous growth. Of course, if it is a cold area, the root shepherd's purse growth time is too short, then you can take spring sowing.

2. Soil requirements

The growth of root shepherd's purse does not have high requirements for soil, generally good ability to preserve fertilizer and water, good drainage, strong air permeability, clay rich in organic matter is better.

3. Planting work

The suitable size of the bed should be dug before the root shepherd's purse is planted, which is about 20-15-15. The row spacing and plant spacing are determined according to the size of different varieties. Remember, if the planting density is too dense, the fleshy root of shepherd's purse will be too small for processing.

4. Fertilization

The growth of shepherd's purse needs more sufficient fertilizer, because as fleshy root vegetables, in addition to nitrogen fertilizer, but also with phosphorus and potassium fertilizer, in order to grow well. Topdressing should be in the order of thinness, thickness and thinness, and you need to decide whether you need topdressing according to its growth, but you don't need fertilizer if you are thriving.

5. Harvest

Because the root shepherd's purse cannot spend the winter on the surface where the frost is more serious, it must be harvested before the frost. How to judge whether it is mature or not? In general, the roots change from green to yellow, and the leaves that appear orange mature.

In areas with heavy frost in winter, root mustard cannot survive in the open field and must be harvested before the frost. In North China, it is cold in winter, sowing early in autumn, and the total growth period is relatively short, usually only about 90 days, which should be harvested from late October to early and middle November. In warmer areas such as Yunnan and Sichuan, the growth period of early-maturing varieties is about 120 days, that of middle-maturing varieties is about 130 days, and that of late-maturing varieties is about 140-150 days. Generally speaking, the suitable harvest time is from late December to early and middle January.

The sign of maturity is that the basal leaves are orange, the root head changes from green to yellow, and lateral branches or buds appear between the axils of the leaves, which should be harvested in time. After harvest, the epidermis thickens, the fiber increases, bolting or hollow, which affects the processing quality. After digging up the fleshy root, cut off the lateral root, cut off all the leaves according to the processing needs, or leave a few green leaves, and then deal with them according to the processing needs. The average yield is about 30000 kilograms per hectare.
