3. Introduction to the Cultivation Methods of Rapeseed Flowers!
1. Land preparation
The land for planting rapeseed flowers should be level, and the soil should be turned over and soft. On high-altitude, poor land, hybrid varieties with winter habit, strong cold resistance, and strong drought tolerance should be selected; on land with fertile soil and sufficient water, varieties with winter or semi-winter habit and strong disease resistance should be used.
2. Sowing
Rapeseed flowers are generally sown from September to October, and the specific sowing time may differ from place to place. They can be direct-sown or raised as seedlings and transplanted. When sowing or transplanting, the distance between each row should be appropriate to facilitate later earthing up and harvesting. Generally, 200 g to 300 g of seed is sown per mu, leaving 8,000 to 14,000 seedlings.
3. Management
When sowing or transplanting rapeseed flowers, apply farmyard manure once. If direct-sown, thin the seedlings promptly after they emerge; if raised as seedlings and transplanted, fill in gaps promptly. Before the soil freezes, take good freeze-prevention measures, such as earthing up and covering with soil; after green-up, topdress promptly and remove weeds; also spray chemicals to prevent and control pests and diseases.
4. Overwintering
Before the soil freezes, rapeseed flowers should be cultivated and earthed up, and earthing up to 8-10 cm is appropriate; before severe cold arrives, topdress with fertilizer and apply more phosphorus and potassium fertilizer; if the weather is too cold, rice straw or other crop straw can be spread between the rapeseed flower rows to keep them warm.
5. Harvest
Rapeseed flowers generally set seed after the flowers fade in March and April and are harvested in May. They are usually harvested in the morning when there is dew, and harvesting at about 80% maturity is better. After harvesting, stack them for 4 to 6 days, then choose clear weather to spread them out to dry, thresh, hull, and winnow. When the moisture content drops to 8-9%, they can be stored in the warehouse.
