Apple Drought Disaster Prevention and Control
1. Adding organic fertilizer, improving soil conservation, and growing organic fertilizers applied in orchard trees, such as ring fertilizer, compost, chicken manure, human waste, various cake fertilizers, grass fertilizer, and green manure, etc., containing a large amount 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.
Second, ridge cultivation technology Orchard ridge cultivation can increase the thickness of soil layer, increase soil permeability, expand the scope of root activity, is conducive to increasing 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.
Third, the orchard cover technology Orchard cover includes film cover and grass cover, film coverage can be antegrade or cover only under the 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.
Fourth, hole fertilizer and water mulch film covering technology Cave storage of fertilizer and water is a mountain orchard efficient water-saving drought-resistant cultivation techniques, generally can save fertilizer 30%, saving 70% -90%. The specific technique is as follows: The crop straws or weeds are bundled into straws 15-25 cm in diameter and 30-35 cm in length and placed in water or soaked in 5%-10% urine. Dig 40 cm in diameter at the edge of the canopy projection 50-70 cm inwards, store the hole slightly larger than the diameter of the grass stem, crown the tree with 3.5-4 meters, dig 4 holes; tree with 6 meters in diameter, dig 6 -8 points. Place the grass stem in the center of the hole, fill it with soil mixed with organic fertilizer, and apply it (5 kg soil fertilizer per hole, add 150 g superphosphate, 50-100 g urea or compound fertilizer), and then sort the tree. The dish is to make the nutrition hole 1-2 cm below the ground, forming a plate, watering 3-5 kg ​​/ hole can be covered; the old agricultural film cut flat, covered in the tree plate, and must cover the nutrition hole In the film, all around and in the middle with soil compaction, each hole cover film 1.5-2 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.
V. Fertilizer spraying in high temperature and dry season, the foliar can continuously spray 400-500 times of urea and potassium dihydrogen phosphate, 800-1000 times of amino acid composite fertilizer, which is beneficial to cooling, supplement water and nutrients, and improve leaf function. . For dry land orchards on hillside, hilly, and unirrigated conditions, spray 1-3 times of 5%-6% turfgrass leaching solution (5-6 kg of plant ash, 100 kg of fresh water, fully immersed in water after mixing for 1-3 times when the temperature is high in June-August. -16 hours, filtration and deslagging, can increase the potassium content of the tree, enhance the drought resistance and high temperature resistance of the fruit tree.
Laser Tape Measure 2 in 1, as its name, it is one product with traditional tape measure and digital laser distance measurer. Laser measure tape can measure 40m with laser measurement and 5m of the measuring tape. Convenient, smart, accurate, laser tape measure make every measurement simple in life!
