The planting techniques of rapeseed are as follows:

1. Site selection and preparation

Rapideseed has a relatively large demand for nutrients, and the soil is responsible for the growth and development of rapeseed to absorb nutrients. The main source of rapeseed is to create an excellent soil growth environment for rapeseed. Therefore, rapeseed should be planted in plots with deep and fertile soil, loose and transparent soil structure, higher terrain, convenient drainage and irrigation, and slightly acidic soil with moderate sandy clay. The best rapeseed planting land is a plot that has not been planted with rapeseed in the past two years.

2. Sun-drying, soaking and dressing seeds

Seeds are contaminated with bacteria. After sowing, rapeseed seeds will rot, uneven emergence, and are prone to disease. If it is not certain whether the seeds are contaminated with bacteria, Under this condition, seeds should be sun-dried, soaked or dressed before sowing or germination. On the one hand, they can kill pathogenic bacteria on the surface of the seeds and prevent diseases. On the other hand, they should improve the physiological activity and germination ability of the seeds.

Before sowing, rape seeds must be sun-dried. 1-2 days before sowing, you can choose sunny weather and choose the period from 9 a.m. to 3 p.m., and place the seeds in a fertilizer bag. Spread cardboard boxes and other items on the sunny ground and dry them for 3-6 hours.

3. Sowing at the right time

In terms of rapeseed sowing mode, the cultivation method of seedling transplanting is generally used in the south, while the cultivation method of direct seeding is generally used in the north. From the perspective of planting scale Generally speaking, areas with large planting areas generally use direct seeding, while areas with small planting areas generally use seedling cultivation. Because winter rapeseed in the south is mostly planted at the end of September, spring rapeseed in the north is mostly planted from March to April.

4. Seedling management of rapeseed

After rapeseed emerges, when 1-2 true leaves grow, the first thinning should be carried out in time, and the spacing between seedlings should be controlled. When the seedlings grow out of the cabbage heart, you can appropriately increase the spacing between the seedlings for the second thinning. When thinning, focus on removing diseased, weak, small, and crooked seedlings. For areas where the seedlings are sparse or uneven, , can be transplanted and replanted from densely grown seedlings.
