Strengthen the shade vegetable cooling facilities with good conditions, we must make full use of scaffolding to cover the shade net, multi-purpose matte film, in order to reduce the sun through the cooling rate. Temporary sunshade can cover the old film and other cooling. The moisture-tolerant vegetables can be turned on at the midday to cool the fog spray facilities, such as celery, leeks, etc., but you can't simply rely on spray watering. High-end rare vegetables, start the water curtain cooling. Conventional vegetables can be combined with watering down the ground sooner or later to ensure root vitality. Lotus roots, arrowheads and other aquatic vegetables are kept in shallow water layers to promote underground growth.
The demand for heat-resistant varieties of green leafy vegetables in summer is large, and it is possible to use idle crops to rush to increase production and income. Such as Chinese cabbage selection Huaguan, Huawang, Xia Di, Dongfang 56, Dongfang 18, Heat 9 and other heat-resistant varieties, as well as leeks, spinach, leeks, etc. should be preferred heat and moisture resistant varieties with strong resistance to Reduce high-temperature physiological diseases.
Optimize the cultivation methods Arrange reasonably between high and short different vegetable varieties, gourd, balsam pear, squash, etc. Cultivate vegetables, make full use of the lower space to sow shade-tolerant vegetables, stems and leaves use high-stemmed vegetables for close planting, natural shade to improve yield quality . When the tomatoes are pruned over the summer, the uppermost layer leaves 2 or 3 leaves. After the cabbage, cauliflower, etc., the outer leaves cover the leaves, the pumpkin, melon and other melon vegetables can be used to cover the grass and prevent sunburn. Causes rotten melons.
Fine management of fertilizers and water during high temperature vegetables should be thoroughly watered. Spraying facilities must be checked carefully to prevent surface humidity and water shortage in the lower roots. Watering should be carried out with "day cool, cool, cool water," and water is the priority for well water. Can not flood irrigation, to prevent physiological water. Fertilization should be carried out in combination with watering to adjust fertilizers with water to increase fertilizer utilization. Foliar fertilizer spray concentration is properly reduced, increasing water consumption. In addition to spraying potassium dihydrogen phosphate, superphosphate, etc., appropriate increase in spraying 0.1% zinc sulfate or copper sulfate solution, can increase the heat resistance of plants, enhance anti-cracking fruit, anti-sunburn ability.
Also, Analog Output, RS485, USB cable is optional. If you have any other requirements of our accuracy distance sensor, please fell free to contact us
Vegetables to deal with high temperature technical measures
After the outbreak of plumping in Nanjing this year, the continued high temperature, most of the vegetables in the field are prone to sunburn, growth stagnation, pollen abortion, falling and fruiting, etc., should strengthen technical measures to ensure the safe production of vegetables at high temperatures.
