Suitable sowing time of direct seeding rape

Seeding early at the right time is an effective way for direct seeding rape to take advantage of the effective growth period before winter and strive for the number of green leaves in winter. There is a saying in the proverb "one more leaf before the year, one more branch after the year". The number of green leaves in winter can synthesize sufficient nutrients, promote the root system to grow deeper and thicker, form a strong root system, and lay a good foundation for increasing branch angles. Sowing late, low temperature growth slow, small winter vegetative body, poor cold resistance, weak growth potential, is not conducive to the formation of strong seedlings of rape. Of course, sowing time is not the earlier the better. The safe sowing time of direct seeding rape in our city is mid-to-late October.
