In the hot summer months, not only people and livestock are prone to heat stroke, the crops also “heat strokeâ€, which causes so-called “high temperature heat damageâ€. The main countermeasures: 1. Cool down with water. In the summer and autumn high temperature season, timely irrigation can improve the microclimate conditions in the field and reduce the temperature by 1°C to 3°C, thus reducing the direct damage to the flower organs and photosynthetic organs of crops caused by high temperature; when the high temperature weather around 35°C is encountered in the early rice filling stage, it should be timely. Irrigation into the field and discharge at night can avoid or reduce the "high-temperature cooking." In some places in the hot season, the practice of irrigating rice in the morning, deep water during daytime, and horse water in the evening is very effective. The cooling effect is also very obvious. It is 5.8%-8.1% lower than that of single irrigation deepwater; Sprayer, spraying cool water directly on the stems and leaves, also has a cooling effect, the cooling rate is generally about 1 °C. 2. Artificially assisted pollination. During the high temperature and drought period, the ability of natural powders to pollinate and powder is reduced. Artificially assisted pollination of cross-pollinated crops such as corn and sorghum can reduce the influence of high temperature on the pollination and fertilization process of the crop, and increase the seed setting rate by 5% to 8% compared with natural pollination. 3. Top dressing. In the high temperature season, spraying foliar fertilizer with urea, human urine, pig cow urine, potassium dihydrogen phosphate solution or calcium superphosphate and ash leaching continuously for many times is not only beneficial to cooling and humidification, but also can supplement the necessary growth and development of crops. Moisture and nutrition, but spraying must be properly reduced spray concentration, increase water consumption. 4. Strengthen management. In the summer and autumn high temperature season, reasonable transport of fertilizer, can improve the nutritional status of plants, enhance the ability to resist high temperature and heat damage; sweet pepper sprayed with 30PPM chlorophenoxyacetic acid solution, has a certain control effect on high temperature caused by falling flowers; tomato spray 2000 ~ 3000PPM long-term (B9) solution, 0.1% zinc sulfate or copper sulfate solution, can improve the heat resistance of the plant, enhance the anti-cracking fruit, anti-sunburn ability, dipping or coating with 2,4 ~ D, can prevent high temperature falling And promote the expansion of ovary; the use of plastic greenhouse cultivation of vegetables, shading net shade covering in summer and autumn, the cooling effect of up to 4 ~ 6 °C, and can prevent heavy rain, hail and locust directly harm the vegetables.
