If there is continuous low temperature, the blooming time will be later, possibly blooming in mid-March.
2. China has a vast territory, and differences in latitude, sea-land distribution, and vertical height can lead to different blooming times for oilseed rape. If it is in the southern part of Taiwan, oilseed rape can bloom at the end of December. If it is in Yunnan, Guangdong, and Guangxi, oilseed rape will bloom in January and February. If it is in the Sichuan Basin and north of Wuyi Mountain, oilseed rape will bloom in March and April. If it is in the Qinghai-Tibet Plateau, oilseed rape will bloom in June, July, and August.
III. Introduction to the Planting Methods of Oilseed Rape
1. Land preparation
The land for planting oilseed rape should be flat, and the soil should be turned over and loose. On high-altitude, infertile land, choose hybrid varieties that are winter-hardy, cold-tolerant, and drought-resistant. On fertile land with sufficient water, choose varieties that are winter-hardy or semi-winter-hardy and disease-resistant.
2. Sowing
Oilseed rape is generally sown from September to October, and the specific sowing time may vary by region. It can be direct-sown or seedlings transplanted. When sowing or transplanting, the distance between each row should be appropriate to facilitate later earthwork and harvesting. Generally, 200 grams to 300 grams of seeds are scattered per mu, with 8,000 to 14,000 seedlings retained.
3. Management
When sowing or transplanting oilseed rape, apply a dose of farm manure. If direct-sown, thin the seedlings in time after they emerge; if seedlings are transplanted, fill in the seedlings in time. Before the soil freezes, take anti-freezing measures such as earthing up and covering the soil. After returning green, apply top dressing in time and remove weeds. Also, spray pesticides to control diseases and pests.
4. Overwintering
Before the soil freezes, cultivate and earth up the oilseed rape, with an appropriate height of 8-10 centimeters; before the severe cold arrives, apply top dressing and increase the application of phosphorus and potassium fertilizers. If the weather is too cold, straw or other crop stalks can be spread between the rows of oilseed rape to keep warm.
5. Harvesting
Oilseed rape generally flowers and sets seeds in March and April, with harvesting in May. It is usually better to harvest in the morning with dew. The harvest should be at 80% maturity. After harvesting, pile the crops for 4-6 days, then spread them out on a sunny day for drying, threshing, and cleaning. When the moisture content drops to 8-9%, it can be stored.
