Rapeseed's growing environment and local conditions

Rapeseed Flower Growth Environment and Conditions

Rapeseed has a well-developed root system and is suitable for planting in loam soil that is deep, loose, fertile, well-structured, rich in organic matter and well-drained. It is more conducive to increasing yield in weakly acidic or neutral soil. It is mainly distributed in the Yangtze River Basin and areas to the south.

Rapeseed growing conditions

Rapeseed is suitable for growing in relatively cool places. It is a plant with strong cold resistance. Moreover, the minimum temperature for seed germination is 3 to 5 degrees. The seedlings can emerge in three days under the condition of about 20 degrees. It needs 18 degrees to bloom. The temperature difference between day and night is large, so it is conducive to the development of flowering and fruiting.

Moreover, rapeseed flowers gain a lot of nutrients during the fruiting period, so they need more water, so watering them 1 to 2 times a day is enough. Rapeseed flowers can absorb fertilizer on their own and have a very strong ability, so they don’t have too many requirements for the soil. Just retain fertilizer and water and keep the soil loose and breathable.

Rapeseed growth temperature

Rapeseed prefers a cool environment and is relatively cold-resistant. The minimum temperature for seed germination is 3-5 degrees. If the temperature is 20-25 degrees, seedlings can emerge in 3 days. The flowering period is 14-18 degrees, and the fruit development period is 12-15 degrees. The temperature difference between day and night is large, so more substances and oils can be accumulated.

Rapeseed flower growth process

There are four stages in the growth of rapeseed flowers. The first is the period of flower bud differentiation, the second is the period of flower bud growth, the third is the period of vigorous flowering, and the fourth is the period of grain maturity.

Rapeseed Planting Time and Method

1. Planting time

   Rapeseed flowers can be planted in autumn and winter, specifically around September to November. Of course, the planting time varies in different regions and can be adjusted reasonably. Some areas are sometimes planted in spring.

2. Planting method

(1) Site selection and land preparation: Before planting rapeseed, you need to choose suitable land. It does not have very high requirements for the soil, as long as it is not heavy and sticky. The soil must also be loosened to prevent soil compaction. You can water it thoroughly once.

(2) Planting: Rapeseed can be propagated by sowing, that is, scatter the purchased seeds into the soil and control the spacing, otherwise the seedlings will grow very closely together. Alternatively, you can buy seedlings and plant them, just keeping a certain distance between them.

(3) Planting management: When the rapeseed seedlings grow to about 20 cm, they need to be weeded and urea should be applied. As the seedlings continue to grow, they need to be fertilized again when they are about 40 cm in height. Farmyard manure can be used for this fertilization.
