III. Introduction to the Planting Methods of Rapeseed Flowers
1. Land Preparation
The land for planting rapeseed flowers should be flat, and the soil should be turned over and loose. On high-altitude, infertile land, choose hybrid varieties that are cold-tolerant and drought-resistant; on fertile land with sufficient water, choose varieties that are winter or semi-winter hardy and disease-resistant.
2. Sowing
Rapeseed flowers are usually sown from September to October, and the specific sowing time may vary from place to place. They can be direct-sown or transplanted, with an appropriate distance between rows for later soil preparation and harvesting. Generally, 200-300 grams are scattered per mu, leaving 8,000-14,000 seedlings.
3. Management
When sowing or transplanting rapeseed flowers, apply a dose of farmyard manure. If direct-sown, thin seedlings promptly after emergence; if transplanted, fill in seedlings promptly; before the soil freezes, take anti-freezing measures such as earthing up or covering soil; after returning green, apply top dressing promptly and remove weeds; also spray pesticides to control diseases and pests.
4. Overwintering
Before the soil freezes, till and earth up the rapeseed flowers, with an earthing up of 8-10 centimeters; before the severe cold arrives, apply fertilizers, especially phosphorus and potassium fertilizers; if the weather is too cold, cover the rapeseed flower rows with straw or other crop stalks for warmth.
5. Harvesting
Rapeseed flowers usually set seeds after flowering in March or April and are harvested in May. It is usually better to harvest in the morning with dew. Harvest when they are 80% mature, then stack for 4-6 days, spread out in sunny weather, thresh, remove the seeds, and clean them when the moisture content drops to 8-9%.
