Energy-saving solar greenhouse overwintering vegetable cultivation. In the middle and early September, cucumbers were sown. The varieties were Jinlu No. 3, Shengfeng No. 3, Jinyou 30, and Jinyou No. 3, which were shaded and rainproofed to cultivate seedlings, and grafted with black-skinned squash to improve the resistance of cucumbers. Sex and cold resistance. Colonization of overwintering tomatoes, peppers and sweet peppers during the winter season will reach 5 to 6 true leaves when planted in a timely manner.

Do not flood the water with slow flooding to reduce stem rot. Delay the cultivation and management of vegetables. For the simple winter shed, medium and small sheds, the delayed cultivation of cucumbers and squash seedlings grows to 3 to 4 true leaves in time for colonization, and the tomato grows to 2 to 3 true leaves in time for seedling splitting. It should be done in the afternoon or evening. Reduce the incidence of viral diseases. The management of open field dishes. For crops such as Chinese cabbage, radish, autumn cucumber, and autumn cowpea, field management should be performed according to growing trends: 1. Watering.
