1. Timely sowing at the right time is one of the important technical measures for spring cabbage cultivation. If the seeding is too early, the seedlings grow more, and the early spring is continuously low temperature, so that the seedlings pass the vernalization stage prematurely, and it is easy to have early bolting. On the contrary, sowing Too late, the maturity period is delayed and the economic benefits are affected. Generally, in the middle and late March, the seedlings are planted in protected areas, the seeds are spread, the seedbeds are irrigated before sowing, and the soil is covered after sowing. The thickness is about 1 ┩, and the seeding amount is about 1 mu. Daejeon needs about 25g of seeds. 2. Seedling management In order to cultivate strong seedlings, temperature management in seedling stage is very important. After sowing, the temperature during the daytime is controlled at 20-25 °C, and at around 10 °C at night. If you encounter low temperature, you need to cover the grass at night, and the temperature after the seedlings are out. It can be appropriately reduced, and it should be ventilated in time, whether it is sunny or rainy. After the emergence of the seedlings, timely prevention and treatment of pests, spraying with sea cockroach insecticide to control Plutella xylostella, spraying with Greenheng No. 1 to prevent the disease of cabbage. The standard of strong seedlings is dark green leaves, thick and large leaves, thick stems, short internodes, well-developed roots, and disease-free seedlings. 3. According to the climatic conditions, it is generally planted in the field in the middle and late April, when the seedlings have 6-7 leaves, and the base fertilizer is applied 10 days before the planting. Generally, 75 kg of n, p, k ternary compound fertilizer is applied per acre. The phosphate fertilizer is 35 kilograms. After fertilization, it is combined with ditching and covering the soil. The width of the widening ditch is 1.2 meters, the row spacing of the planting plants is 4050 cm, and the seedlings per acre are 3000-3200. 4. Datian management should be timely watered after planting to increase the survival rate of seedlings. During the growth period, the drainage should be cleaned and the root system should be well developed. Timely use Haizheng worm to spray to prevent the harm of cabbage caterpillar. In the rosette period, it is necessary to topdress in time to promote the rapid expansion of the leaf ball, and stop fertilizing 1 month after the rosette period. 5. Harvesting is generally in the middle and late June. When the leaf ball is fully grown and compact, the ball can be harvested when the ball weight is 1.5-2┧. It can also be harvested according to the market conditions. If the vegetable price is low at this time, it can be delayed. Harvested.
