How long does it take for rapeseed to germinate?

Rapeseed likes cool conditions and has strong cold resistance. The germination and emergence of rapeseed seeds generally go through the following four stages: water absorption and swelling, seed germination, seed germination, and cotyledon expansion. Under 20-25℃ conditions, rapeseed seeds can germinate in 4 days.

Rapeseed germination time

Spinach is generally sown in spring and autumn. The daylight hours are relatively long in these two seasons, which can provide a high-quality growth environment for rapeseed. At this time, rapeseed can be seen emerging about 5-7 days after sowing. Adequate light and suitable temperature can ensure the healthy growth of rapeseed.

Rapeseed post-emergence management

1. Timely fertilization and thinning can supplement nutrients for rapeseed growth and ensure that the roots and leaves can be stronger. If thinning is not done in time, the seedlings will lack nutrients and some rapeseed will be small and weak, which will seriously affect the yield.

2. Excessive soil moisture during the rapeseed growing period will make the soil air permeability poor and the organic matter will decompose slowly, resulting in fertilizer loss and reduced nutrition. During the rapeseed growing period, it is necessary to check the soil moisture in time and drain it in time to prevent water accumulation.

3. The temperature and soil during the growth period of rapeseed seedlings are suitable for the growth of weeds. Weeds should be removed in time to prevent them from competing for the nutrients and water needed for rapeseed growth, otherwise it will affect the growth of rapeseed.
