1. Soil preparation and fertilization

The adaptability of small rape is strong, and the requirement for soil is not strict, but it is suitable for deep, fertile and loose soil. The oil content is high in neutral and slightly acidic soil, but low in alkaline soil. Its planting is small and its top soil capacity is poor, so it should be cultivated in time after the previous harvest so as not to lose soil moisture. Small rape needs a large amount of fertilizer, especially phosphate fertilizer, and the base fertilizer is high-quality mature organic fertilizer. In order to have complete seedlings, uniform seedlings, strong seedlings, and lay a solid foundation for the whole growth period, winter rape needs to be watered one week before sowing.

2. Seed treatment

Before sowing, the seeds need to be dried, selected, disinfected and so on. First, the seeds are put on the field to dry for 2-3 days, then the seeds and impurities with a small proportion are removed, and then soaked in 10% salt water to select the blighted seeds. Soak the selected seeds in warm water of about 50 degrees for 20 minutes. If possible, soak the seeds in formalin 300 times solution for 20-25 minutes. After fishing out, sow for 2 hours and rinse with clean water.

3. Sowing seeds

The sowing time of small rape should be 18-20 degrees. First of all, the land with loose and fertile soil and convenient drainage and irrigation should be selected and sufficient base fertilizer should be applied. The sowing time of seedling bed can be about a week earlier than that of the same variety, and the amount of seeds per mu is about 0.8 kg. When the seedlings grow two true leaves, the seedlings are fixed when the seedlings are 3-6 cm apart and 3-4 true leaves are produced, and the plant spacing is determined according to the planned density. If the pest is serious, the seedling setting should be postponed in time, and the seedlings should be replanted when the seedlings are missing.

4. Field management

After planting, 5 kg of nitrogen fertilizer can be applied per mu, retained by strong roots, and watered once after topdressing. Wax fertilizer should be applied once before overwintering, and overwintering water should be irrigated 10-15 days before freezing. After thawing in spring, we should go to the overwintering cover soil in time, remove the loose soil to preserve soil moisture, promote spring hair, first apply moss fertilizer before bolting, apply 10-15 kg ammonium sulfate per mu, and pay attention to the application of trace fertilizer at the same time.
