In response to this situation, we started the experiment of covering cultivation in 1988 (also known as shading net) with the support of the Municipal Vegetable Office and covering an area of 20 mu. In 1989, 150 mu of demonstration and extension area were cultivated with a coverage of 675 mu. The main coverage varieties Cabbage, cabbage, mustard, lettuce leaves (lettuce), coriander and early cabbage, cauliflower early breeding. After investigation,
