Sunshade net mulching cultivation of onion and garlic vegetables

Leeks, onions, garlic and other onions and garlic vegetables like cold climate, poor heat tolerance, but good negative tolerance. Covering cultivation with sunshade net in high temperature season in summer and autumn can promote growth and improve unit yield and quality. For example, after the leek is covered, the leaf tip is not scorched, the leaf is green, and the quality is obviously improved. After the garlic planted in August was covered with sunshade net, the seedling rate increased by 44.54%, and the plant height and the number of leaves increased significantly.

The cultivation of onion and garlic vegetables covered with sunshade net can be covered with floating surface before emergence after sowing, and covered with greenhouse, flat shed and small arch shed after emergence. Floating cover can be covered with multi-layer mulch or covered with straw and other mulch on the Internet, which can be opened in time after emergence. The greenhouse and other scaffolding should be covered early and uncovered at night, but the daytime covering time can be longer than that of other vegetables, and continuous mulching can also be adopted when the greenhouse is covered to save labor.

In recent years, some vegetable farmers in the suburbs of Wuxi City, Jiangsu Province have used sunshade net to cover and cultivate leek in summer and autumn, and achieved better economic benefits. From June to July, the small arch shed was used to cover 2-3 layers of sunshade net on the leek, and then covered with Zizania caduciflora straw or rice straw outside the sunshade net, so as to create a growing environment that is not only ventilated, but also sunshaded and cool, so that the leek forms leek.
