(1) Sound drought monitoring, early warning systems, and service systems The agricultural science and technology departments and meteorological departments around the country should understand the laws of local drought disasters and establish real-time monitoring and early warning systems for drought disasters to mitigate the effects and losses of drought disasters. To carry out drought monitoring, early warning, and assessment operations, it is necessary to make predictions and early warnings before the occurrence of droughts; during droughts, it constantly monitors the degree of drought, development trends, and impact on people’s lives, and provides timely drought to relevant departments. Regional, time, and hazard levels, as well as drought prevention and reduction measures, provide services for disaster prevention and reduction. (2) Strengthening water conservancy infrastructure construction The construction of various types of water conservancy facilities according to local conditions, treatment of river courses, timely storage of rainwater, and complete irrigation systems are the fundamental measures for preventing drought. All localities should increase investment in water conservancy construction, build water conservancy facilities, improve the ecological environment of farmland, and strive to achieve drought and energy irrigation, and encounter flooding. Where conditions permit, water saving irrigation methods such as drip irrigation, sprinkler irrigation and micro-spraying should be actively implemented. (3) Agronomic Techniques for Drought Prevention 1Add organic fertilizer, improve soil conservation, and cultivate roots and trees: Organic fertilizers applied in orchards, such as ring fertilizer, compost, chicken manure, human waste, various cake fertilizers, grass fertilizers, and green manure, contain large amounts of organic matter. After the soil is decomposed by microorganisms and physical and chemical changes form humus, the tiny soil particles can be bonded together to form a water-stable aggregate structure, which makes the clay soil loose and easy to cultivate, and the sandy soil becomes a structured soil. . After the soil structure is improved, the water permeability and water retention and fertilizer retention of the soil are enhanced, so that the ability to retain fertilizer and water is improved, a good ecological environment condition is created for the growth of the root system, and comprehensive technologies such as thinning and fruit thinning, reasonable pruning, and protection of the leaves are combined. Measures to achieve the purpose of raising roots and trees and improve the ability of trees to fight drought. 2 ridge cultivation techniques: Orchard ridge cultivation can increase the thickness of soil layer, increase soil permeability, expand the scope of root activity, and help to increase the number and proportion of underground new roots of fruit trees. In the thin orchard, the ridging under the trees has the function of improving the soil conservation function, stabilizing the micro-environment of the rhizosphere soil of the fruit trees, protecting the growth of the root system, and improving the ability of drought resistance. 3 Orchard Covering Techniques: Orchard coverings include film coverings and grass coverings, which can be covered in a straight line or only covered under a tree plate. The film under the tree can reduce the evaporation of water and increase the soil moisture in the rhizosphere; the weeds, leaves, crop stalks, and firewood can be used to cover the ground of the orchard. Spring covered hay and summer pressed grass. The thin layer of orchard can be a combination of trenching and grass cover. Orchard and grass cover can effectively reduce surface water evaporation and increase surface moisture. 4 points storage fertilizer and water mulch film cover technology: point storage fertilizer and water is a mountain orchard efficient water-saving drought-resistant cultivation techniques, generally can save 30% fertilizer, saving 70% to 90%. Specific techniques are as follows: The crop straws or weeds are bundled into straws with diameters of 15 to 25 cm and lengths of 30 to 35 cm, and are soaked in water or 5% to 10% of urine. In the crown projection edge inwards 50 to 70 cm deep 40 cm, a diameter larger than the grass holding point, a 3.5 to 4 m diameter tree, digging 4 points; 6 m diameter tree, digging 6 ~8 points. Place the grass stems in the center of the hole, fill it with soil mixed with organic manure (about 5 kilograms of soil miscellaneous fertilizer per hole, add 150 grams of superphosphate, 50 to 100 grams of urea or compound fertilizer), and then sort the trees. The nutrition point is 1~2cm below the ground to form a plate, watering 3~5kg/hole can be covered with film; cut the old agricultural film flat, cover it on the tree plate, and must cover the nutrition hole In the film, all around and in the middle with soil compaction, each hole covering the film 1.5 to 2 square meters, the edge of the plastic film with strict pressure, the center is on the straw to wear a small hole on the top, blocked with stones or soil in order to catch fertilizer in the future water. Generally after the flowering (mid-May mid-term), the new shoots stop growing period (mid-June), and after the fruit-picking period, 50 to 100 grams of urea or compound fertilizer is applied to each hole, and the fertilizer is placed on the top of the grass. About 3.5 kg watering; into the rainy season, you can remove the film, so that the storage of rainwater within the hole; general storage can maintain 2 to 3 years, the grass should be changed once a year, found that the film should be replaced after the damage, set the storage again Change points when you are in a hole. 5Foliar Spray Fertilizer: During high temperature and dry season, the foliar can continuously spray 400-500 times of urea and potassium dihydrogen phosphate, and 800-1000 times of amino acid compound micro-fertilizer, which is conducive to cooling, supplement water and nutrients, and improve leaf function. . For dry land orchards on hillside, hilly, and unirrigated conditions, 6~8 months of continuous high temperature spraying of 1-3% of 5%~6% turfgrass leaching solution (grasswood ash 5~6kg, add fresh water 100kg, soaking 14 times after fully stirring) ~ 16 hours, filtration and slag removal, can increase the potassium content of the tree, enhance fruit drought resistance, high temperature resistance.
