Basic process of rapeseed from sowing to harvest

Rapeseed is also called oil Chinese cabbage. Oil Chinese cabbage originated from the napa cabbage of southern China. Unlike napa cabbage, oil Chinese cabbage is dark green in color rather than white. Its taste is also very different. Although the market price of oil Chinese cabbage is relatively low, its market demand is very large. As the saying goes, many a little makes a mickle, so there is still a certain planting prospect. So today, the editor will explain to you the specific process of growing oil Chinese cabbage. Let's take a look together below!

1. Base fertilizer

Before sowing, sufficient base fertilizer needs to be applied. After plowing and sun-exposing the land, apply an equivalent amount of base fertilizer according to the area of the land. The base fertilizer is mainly farmyard manure, supplemented by compound fertilizers such as potassium phosphate. Mix it thoroughly with the soil to enhance soil fertility, promote seed germination and seedling emergence. It can also enhance the resistance of seedlings, reduce the incidence of pests and diseases, and lay a good foundation for high yield and high efficiency.

2. Seed selection

No matter what you plant, the first step is to choose a good variety. The quality of the variety is directly related to the later yield. Therefore, when choosing a variety, we should choose excellent varieties with high yield and strong disease resistance. This can save a lot of trouble in later management and achieve twice the result with half the effort.

3. Seed soaking

When it cannot be determined whether the seeds contain potential pathogens, the seeds should be soaked to eliminate the pathogens in the seeds. First place the seeds under the sun to sun-dry for three hours, then soak the seeds in clean water at about 50°C until the water temperature drops to 30°C, then after another two hours remove them and air-dry them before sowing.

4. Sowing

There are also certain requirements for the sowing time. The most suitable sowing season is spring, and sowing can be done around March each year. Therefore, we need to complete all preparatory work before March, such as base fertilizer and seed soaking. When sowing, according to the moisture condition of the soil, water the soil to create moisture, and sow after the water has fully entered the soil. Pay attention to the sowing density and dig the beds well to facilitate later management.

5. Management

When the seedlings emerge and grow two true leaves, the first thinning work needs to begin, controlling the spacing of all seedlings at about 3 cm. The second thinning is done when the heart of the vegetable grows, and the planting density needs to be further expanded. During the seedling emergence stage, the water demand is not large, so there is no need to water as long as the weather is not too dry. During the growth period, water at least three times, and do not do it in cloudy and rainy weather.

6. Drainage

Oil Chinese cabbage is extremely intolerant of waterlogging, and because the sowing time is in the rainy spring, we should pay attention to drainage in the garden. If drainage is not done in time, accumulated water will not only have a considerable impact on the growth and development of oil Chinese cabbage, but also cause various diseases. Therefore, drainage work after sowing is very important, and it is best to set up waterproof facilities.

The above is the basic process of growing oil Chinese cabbage. Growing oil Chinese cabbage is relatively simple, but it is relatively difficult to manage. Pay attention to timely topdressing, especially half a month before harvest, apply an appropriate amount of urea according to the planting area to improve the quality of oil Chinese cabbage. It is also necessary to prevent and control the occurrence of various pests and diseases in order to truly achieve high yield and high efficiency. Alright, that is all for today's introduction.
