Planting time of rapeseed:

Rape is very adaptable and has good heat and cold tolerance. It can be planted all year round. Under normal circumstances, we can plant in spring and harvest in autumn, or in summer, we can harvest in autumn, and we can harvest before planting New Year's Day in early autumn. For the northern winter, we should try to choose indoor planting.

Planting method of rape and wheat:

1. Variety selection

To grow rape, we should first choose varieties that are heat-resistant, disease-resistant, high-quality and high-yielding, such as sesame oil.

2. Seed treatment

As the seedling stage of summer stubble wheat and vegetable is in the high temperature, early dry and rainy season, it is best to soak the seeds to promote sprouting before sowing. The seeds were wrapped in gauze and soaked in cold water for about 1 hour, then picked up and placed under the condition of 15 ℃ ~ 20 ℃ to accelerate germination. The seeds were exposed for 2 to 3 days and then sowed.

3. Cultivation and management

Plots with high topography, fertile soil, good permeability and no Compositae crops should be selected for planting. Apply sufficient base fertilizer, 5000 kg of high-quality organic fertilizer, 40 kg of diammonium phosphate and 20 kg of urea per mu. To raise seedlings in the open field, after sowing, it is necessary to build a small arch shed with 2-meter-long bamboo sheets on the seedbed bed, and then cover the small arch shed with an old film to protect against rain and cool down. Keep the field moist and the soil loose throughout the growth and development period. During the growth period, foliar fertilizer should be applied for 2 times in combination with water spraying, usually with 0.2% potassium dihydrogen phosphate solution.

4. Timely harvest

When the number of leaves of rape reaches 20-25 and the plant height is 30-40 cm, it can be harvested at a distance of 2-3 cm from the ground.
