First, timely irrigation or foliar spray. For an orchard with a more convenient water source, a small amount of irrigation can be used to keep the soil moist. It is also possible to spray the crown several times before 9 o'clock in the morning or after 4 o'clock in the afternoon to cool the entire tree crown while giving the trees The body replenish moisture and reduce fruit drop caused by high temperature and water shortage.
Second, cover the tree disk extension weeding. Coverage is a fundamental measure to reduce the evaporation of groundwater. It can make full use of wheat straw, weeds, etc. to cover tree trays in orchards. The orchards in this period are covered with weeds. Do not rush to weed control. Weeds can be used to cover water, preserve water, and slow evaporation of water. Mitigation of drought hazards.
Third, reduce the amount of pruning. The summer cut of the fruit trees during high temperature and drought will increase the wounds of the branches and increase the transpiration of the trees, which will certainly increase the damage. If it is necessary to prune, some pests and branches, weak branches, and legged branches may be properly removed and trimmed, and they may not be sparse, heavy-cut or short-cut. Reduce the transpiration of water and nutrient consumption and over-evaporation and burn of leaf surface moisture, and reduce the impact of drought on the fruit.
Fourth, increase the frequency of foliar spray fertilizer. When the fruit trees are exposed to high temperature and drought, the photosynthesis of the leaves and the absorption of the roots on the fertilizers will be significantly reduced, even the leaves will shrink, resulting in deciduous fruit drop. In severe cases, the growth restriction of the shoots and roots and the fruit enlargement will be forced to stop. Such phenomena. Therefore, in the prevention of pests and diseases, urea, potassium dihydrogen phosphate, borax, calcium superphosphate leachate can be added to supplement the lack of rhizome fertilization, thereby enhancing the tree vigor and improving drought resistance. Its application concentration is: urea 0.2%~0.3%, potassium dihydrogen phosphate 0.2%~0.3%, 0.3%~0.5% of superphosphate leaching solution, 0.3%~0.5% of potassium chloride, 0.3%~0.5% of borax, ash extract of plant ash 0.3% to 0.5%, fresh biogas slurry 5%; glutinous globulin "Zhuang root nutrient solution", PBO, etc. according to the instructions.
5. The trunk is painted white. Lime and water are filtered by gauze in a ratio of 1:10 and sprayed directly onto the trunk and main branch with a sprayer, which has a reflection effect on sunlight and can reduce direct sunlight on the tree body, thereby reducing humidity and reducing evaporation. Branches and leaves can be sprayed with multiple Bordeaux mixture (copper sulfate: quicklime = 1:2, water is generally 160 ~ 240 times). In addition to drought resistance, it can also prevent and treat apple early defoliation, rotten fruit disease, or spraying with 0.03% to 0.05% aspirin solution to reduce water loss, increase drought resistance, and prevent drought and fruit drop.
There are many kinds of raw materials and different properties of cosmetics. According to the properties and uses of raw materials, cosmetics can be generally divided into two categories: substrate raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in the formula of cosmetics, and is the substance that plays the main function in cosmetics. The latter are responsible for forming, stabilizing or giving color, fragrance and other properties of cosmetics, which are used in small amounts in cosmetic formulations but are extremely important. Cosmetics are chemical mixtures made from natural, synthetic or extracted substances with different functions, which are processed by heating, stirring and emulsifying.
