The optimal temperature for seed germination of Chinese cabbage is 25°C, and the optimum temperature for seedling growth is 20-25°C. However, the temperature is often high during the sowing season of Chinese cabbage. High temperature and drought are one of the main factors causing viral disease in Chinese cabbage, in order to prevent high temperatures. For the damage to seedlings, the following measures can be taken:
(1) It is best to control the sowing time scientifically to control the seedling emergence in the evening or at night, so that the seed will not be damaged by the high temperature just after it is unearthed.
(2) Watering water in time is the most effective measure to prevent high temperature. For a long time, farmers planted cabbage to sum up the valuable experience of “three waters, three seedlings and five watersâ€.
(3) Sprinkler irrigation is very beneficial to the emergence and seedling growth of Chinese cabbage. On the one hand, it can fully meet the needs of seedlings for water, and at the same time, it can keep the surface moist and effectively change the microclimate conditions of the vegetable field, which is more ideal for cooling.
