Seed seeding method of Chinese cabbage

It is very important to sow Chinese cabbage seeds in due course. Choosing the right sowing time to meet the environmental conditions of cabbage seeds at all stages is the key to harvesting. There are two kinds of sowing methods: Live and seedling.

1. Live broadcast: Live streaming is the main way of cultivation. Chinese cabbage seed Live is in the whole good ridge or furrow groove, deep about 1.5 cm, artificial trench sowing, and then soil cover, repression, each acre with a seed of 150~200 grams.

2. Seedling: Cabbage seed seedling beds to choose high, fertile, well-drained plots, autumn sowing period can be 3-5 days earlier than live broadcast, seedling stage 20-25 days. Winter and Spring season temperature is low, seedlings grow slowly, it takes 40-50 days to seedling age. Late spring, hot summer season temperature is high, seedlings grow rapidly, it takes 25-30 days to seedling age. When raising seedlings, appropriate protection facilities should be adopted according to the characteristics of local seasonal climate. Winter sowing precocious cultivation, because of the cold winter season, it is advisable to use high-efficiency energy-saving solar greenhouse sowing seedling cultivation. Spring sowing premature cultivation, because of the low temperature in early spring, it is advisable to use ordinary solar greenhouse sowing seedling cultivation. Late spring summer planting, because of late spring and evening temperature is low, it is advisable to sow seedlings in plastic arch shed, open the open. Summer early ripening cultivation, because the summer climate is hot and rainy, to use the shade to cool sowing seedlings, or live after the grass, watering and cooling seedling preservation cultivation, and to pay attention to the drainage after the rain.

3. Temperature control: Chinese cabbage seeds generally in 2℃~13℃ after 10-25 days through spring to form flower buds and bolting flowering, so the lowest temperature of spring seedbed should be mastered in more than 15 ℃, after planting to avoid 10 ℃ below the low temperature. Summer high temperature period should pay attention to shade cooling seedlings, pay attention to watering and cooling seedling preservation. When sowing, pour the bottom water, keep the bed soil moist, in order to facilitate the seedling unearthed. Seedling and planting should be watered in time, especially in the summer high temperature period, after planting to 1~2 the slow seedling water, after 5-7 days to pour 1 water, should not be flooding, the rainy season should pay attention to drainage waterlogging, prevent the occurrence of soft rot.
