growing environment
Under normal circumstances, cabbage seeds are collected in autumn in the north. In the first year, leaf bulbs are formed to complete vegetative growth, vernalization is completed at low temperature in winter, and the photoperiod is completed by long sunshine in the next spring, so that they bloom and bear fruit.
Its growth process is basically the same as that of Chinese cabbage in each growth period. However, the number of days required for each growth period is longer, and the germination period needs 8-10 days; The seedling stage takes 25-30 days; In the rosette stage, it takes 20-25 days for early-maturing varieties and 30-35 days for middle and late-maturing varieties; It takes 20-25 days for early-maturing varieties and 30-50 days for middle and late-maturing varieties.
Cabbage is a winter-strong crop. The change from vegetative growth to reproductive growth requires strict environmental conditions. It requires that the seedlings grow to a certain size before they can receive low temperature induction, and vernalization can be completed in 50-90 days at 0-12 C.
Regarding the photoperiod, the requirements of pointed and flat-headed varieties are not very strict, while those of ballpoint pen-headed varieties require long sunshine. After entering the reproductive growth period, it generally goes through bolting period, flowering period and fruiting period. The flowering period takes 30-40 days, and the fruiting period takes 40-50 days.
