How many times can rapeseed be planted in a year? Specific planting and harvesting times

How many seasons can rapeseed be planted in a year?

Rapeseed can generally be planted twice a year and is divided into winter rapeseed and spring rapeseed. It is an annual plant that blooms once a year. Winter rapeseed is generally planted from September to November each year, and spring rapeseed is generally planted in April each year. If sowing in autumn and winter in northern regions, be sure to pay attention to cold and frost prevention.

Rapeseed Planting Conditions

Rapeseed is a cold-loving crop. Rapeseed seeds can germinate at 3-4℃, and the suitable temperature during the growing period is around 25℃. Rapeseed is suitable for planting in areas with relatively large temperature differences. Excessive temperature differences are conducive to the development of rapeseed and the accumulation of nutrients, and the subsequent oil quality will be higher.

Rapeseed has very high requirements for light growth. If the light is strong, the leaves are prone to aging and the quality is reduced. However, if the light is too weak, the leaves are light in color, which can easily cause excessive growth, increased fiber content, and poor quality. When the sunlight is too strong, you must pay attention to shading cultivation. During the seedling stage, you must thin out the seeds in time or transplant them early, keep a distance, and ensure a certain amount of light.

Rapeseed harvest time

It takes about 90 days from sowing to harvesting rapeseed, and it can be picked and eaten when it is mature. Winter rapeseed is generally planted in the Yangtze River Basin. The growing period is from September of each year to May of the following year, and it matures and goes on the market. It takes about 8 months from planting to harvesting . Spring rapeseed is mainly planted in the Northeast and Northwest regions. It is generally planted in late April and harvested at the end of September. It takes 5 months from sowing to maturity and listing .
