Water-permeable plastic film is a new type of functional plastic film developed by the Comprehensive Research Institute of Agricultural Resources of Shanxi Academy of Agricultural Sciences. It has all the advantages of ordinary plastic film, but also has two functions of water seepage and micro-ventilation, which is conducive to the proliferation of good aerobic beneficial microorganisms in the rhizosphere and the decomposition of nutrients in soil, and to improve the microenvironment of the crop rhizosphere, increase production and income. In the past three years, we have applied water permeable plastic film to tomatoes, green peppers, zucchini, cucumbers, eggplants, legumes, peppers, celery, lettuce, cabbage, cauliflower, cabbage, and other vegetables, and achieved better results: water-permeable plastic film covering Precooked vegetables to cover about 1 week earlier than the ordinary film, the total production increased by 18% -23%. The following describes the application of several water permeable film in different types of vegetable cultivation for reference. I. Application of Solanaceous Fruit Vegetables in Protected Areas This kind of vegetables should be cultivated in wide and narrow rows with widths of 60-80cm or narrow rows of 50-60cm depending on the variety and planting requirements. Starting from a half-height ridge, full base fertilizer is applied, and full-film and under-film irrigation are used. Under conditions, drip irrigation under the membrane can be used. The width of the water-permeable plastic film is 1-1.2m, horizontally or longitudinally laid, and the laminated film made of iron rope is pressed one by one. Between the rows can be planted 1 茬 early cabbage, lettuce or rape vegetable crops, planted by planting hole spacing, management and ordinary plastic film covering. Second, the application of leafy vegetables in the solar greenhouse The leafy vegetables can be covered by a film, a pod, and a flat mulch. Each pod has 3-4 rows, and the pod is about 1m wide. The water-permeable plastic film is covered by a film in each longitudinal direction, pressed and pressed. According to the species, the row spacing is determined, and punchers are used for planting. Third, the application of Daejeon vegetable cultivation Pigment pepper, onion cultivation 1.4m width of the water-permeable plastic film can be used, each diaphragm, diaphragm width 1.2m, 4 lines per planting, plant spacing according to species requirements. Solanaceous vegetables in early spring can be used 80cm width of the water permeable film, made of the corresponding half-high ridge, management with the common film, can not pull the film after harvest, and then plant cabbage or autumn vegetables, a multi-purpose membrane. The water-poor areas can be covered with flat and one-for-one membranes, which can effectively utilize rainwater resources and produce a bumper harvest. Fourth, the use of water seepage film should pay attention to a few issues 1. Base fertilizer must be sufficient, especially when planting with clams, we must fully consider the fertilizer consumption of the crop, according to the amount required to apply. 2. After laminating, it must be pressed tightly to prevent damage, especially when it is applied in Datian. 3. The squat or half-height ridge should be done well to make the permeable film as contact with the ground as possible. China Agricultural Network Editor
