1, soil selection. Should choose deep soil, loose structure, good drainage, adequate nutrients, slightly acidic soil planting. Sandy viscous moderate, high terrain, low water table, not easy to waterlogging, convenient drainage and irrigation of the rice harvest field is very suitable.

2, sowing. Strip sowing is a common cultivation method of rape, with a developed root system, strong ability to absorb water and fertilizer, cold, drought and disease resistance, but due to the small seeds of rapeseed must be so fine ground preparation, adequate bottom fertilizer and selected seeds.

3, land preparation. The whole land is required to be fine and smooth. Dig a good drainage ditch, according to the size of the field to open the box, the size of no strict requirements, but must be able to drain smoothly.

4, the bottom of the fertilizer. With 1,000 pounds of well-rotted farmyard manure and 40 pounds of calcium mix evenly into the sowing ditch.

5, sowing. Before sowing, be sure to sunshine seeds. The row spacing of strip sowing is 1.2 feet. Because the seeds are small, so the seeds should be sown with 30-50 pounds of fine manure plus about 10 pounds of fire ash mixing, mixing the seeds with a small amount of fine manure mixing the seeds evenly and then gradually add mixing until the mixing of the manure. The required boron fertilizer can be mixed in together.

6, field management. Generally, when the rape grows to 3-4 inches, it is necessary to pull out the diseased and weak seedlings, and the curved foot seedlings.

7, pest control. The whole growth period of rape is very sensitive to nitrogen, phosphorus, potassium and boron. Nitrogen deficiency leaves reddish foot leaves senescence and shedding; phosphorus fertilizer is conducive to root growth to enhance resistance; potassium fertilizer can improve the role of disease resistance, resistance to cold, resistance to collapse; boron deficiency will make rapeseed unsaturated, affecting the yield and oil production rate.
