The Main Points of Covering Cultivation Techniques of Vegetable Insect Nets in Sichuan after the Disaster
Applications Leafy vegetables (Chinese cabbage, summer cabbage, summer cabbage, spinach, lettuce, cauliflower, radish, etc.), eggplant (green pepper, eggplant, tomato, etc.), melons (melon, pumpkin, watermelon, etc.), beans Vegetable production and nursery.
Coverage
1. Covering the greenhouses The insect nets are directly covered on the scaffolds, and the soil or bricks are tightly pressed around them. The laminating pipes (shelves) are fastened with a lamination line, leaving the main door uncovered for ease of operation.
2. The small arch cover covers the insect net covering the top surface of the arch and is tightly sealed around. Afterwards, the watering is directly poured on the net until it is harvested.
3. Horizontal scaffolding covers about 1hm2 of vegetable land, all covered with insect nets. This covering method saves insect nets and net racks and is easy to operate.
Technical points
1. Select the appropriate varieties to select the related varieties that are resistant to heat, heat and disease. The varieties of vegetables suitable for planting in Sichuan include: Chinese Cabbage (Beijing No. 61, "Beijing Orange Red Heart, Spring and Summer King, Xiayang, Early Maturity No. 5", etc.), Cabbage (Xiaguang, Zhengchun, Yanchun, Zhonggan 16 to 20). No., etc.), Lettuce (Daibai, etc.), Huacai (Snow Mountain, Baiyu, Baiyang, etc.), Pepper (Zhongjiao No.6, Zhongjiao No.13, Zhongjiao No.16, Zhongjiao No.12, etc.), Eggplant (White) Eggplant, purple long eggplant, etc.. In addition, oil and wheat dishes, spinach, peas, Hu bean, radish, vegetables, cucumber, green beans, leeks, spinach, melon and other can also be used.
2. Select the appropriate insect net According to the conditions of the vegetable fields and different crops, it is currently more suitable to be 20-25 mesh, wire diameter 0.18mm, width 1.2-3.6m, white. If you need to strengthen the shading effect of the insect net, silver gray or gray and black insect nets can be used. Silver gray insect nets are better at avoiding fleas.
3. Correctly cover the insect nets The insect nets must be tightly soiled around the perimeter to prevent insects from sneaking into eggs. When the small arch covers the cultivated vegetables, the height of the arch shed is higher than the height of the crop, and the vegetables and leaves are prevented from clinging to the insect nets, so that pests outside the net feed on the vegetables and leaves, and eggs are laid on the leaves. Check the damage of the insect nets at any time and block the gaps and gaps in time.
4. Handle field management (1) Implement full-coverage coverage. Insect nets do not shading much, and there is no need to uncover the night cover or cover it. The general wind does not need to press the network cable. In the case of 5-6 level winds, the network cable must be pulled to prevent it from opening. (2) spray water cooling. Insect nets have good pest control effect, but when the temperature is high, the net temperature and ground temperature in white pest control nets are about 1 degree C higher than those outside the net, which has a certain impact on vegetable production. Therefore, when the temperature is particularly high in July-August, the number of waterings can be increased and the humidity in the net can be kept to cool down.
Precautions
1. Choose pollution-free organic fertilizers, biological pesticides, and non-polluting water sources.
2. During the production process, it is necessary to pay attention to rainstorms, strong winds, and timely prevention and control of various insect pests and virus diseases.
Origin in Xinjiang, the largest origin of raisins in China. Raisins can contain up to 72% sugars by weight, most of which is fructose and glucose. They also contain about 3% protein and 3.7%–6.8% dietary fiber. Raisins like prunes and apricots are also high in certain antioxidants, but have a lower Vitamin C content than fresh grapes. Raisins are low in sodium and contain no cholesterol. Among individuals with mild increases in blood pressure, the routine consumption of raisins (three times a day) may significantly lower blood pressure, especially when compared to eating other common snacks.
