Brassica chinensis likes a cool environment, is not resistant to high temperature and drought, and has a short growth period. When the temperature is suitable, it only takes 40-50 days for the growth period to be harvested one after another. It can overwinter in the open field in the Yangtze River Basin, and it is easy to bolt in early spring. When the temperature exceeds 25 ℃, the fiber increases, the plant is easy to senesce, the taste becomes bitter, and the palatability is poor. According to the above characteristics, Brassica chinensis can be cultivated in autumn, overwintering, summer and protected areas.

The suitable temperature for germination of Brassica chinensis is 20-25 ℃, so autumn cultivation generally starts when the temperature drops below 25 ℃. In the Yangtze River basin, it is generally sown before and after the end of summer. If you want to cultivate in advance, you need to use a double-layer shade net to shade after soaking the seeds at low temperature, and then carry out routine management after the temperature is lowered. The sowing time can be carried out half a month in advance.

Places with high summer temperatures are not suitable for summer cultivation. In places with cool climates, it can be sown after Brassica chinensis starts to bolt, and can be harvested in 40-50 days, which can avoid the high temperature in summer. If a double-layer shading net is built in summer, the temperature can be kept below 25°C, or sowing can be carried out in summer, and Shanghai green can be harvested before the continuous high temperature.

The economic benefits of cultivating Brassica chinensis in protected areas are not high. Generally, the small arched sheds of Brassica chinensis button cultivated over winter can continue to grow and harvest at any time during the high temperature period in winter. In cold areas, Shanghai green cannot be overwintered in the open field. You can sow Shanghai green when the temperature drops below 25°C. Plant Shanghai green in a solar greenhouse or a small arched shed. When the temperature is below -2°C, cover the outside with straw curtains, etc. material coverage. The Shanghai green cultivated in the protected area is generally closed when the temperature drops below 10 ℃, which can speed up the growth rate of Brassica chinensis in the shed.
