Five measures against drought in fruit trees in hot weather


In the hot and dry season, the continuous hot weather has a great influence on the growth and development of fruit trees. To deal with hot weather orchard management must pay close attention to the implementation of drought prevention measures.
1, irrigation drought. It is necessary to add moisture in time to keep the roots of the fruit trees moist. Those who have irrigation conditions must timely apply irrigation and drought irrigation; if they do not have irrigation conditions, they should be watered once every two weeks, and the amount of water per acre should not be less than 3,000 kg. Especially young orchards, because the roots are shallow, they must be fed more than once in a timely manner to supplement the moisture of the tree and promote normal growth and development.
2, grass cover insurance. Grass cover can keep water cool, loosen soil, and improve soil microorganisms. The weeds in the garden should be cleaned and covered with grass before the grass is covered. Straw, soft grass, etc. are covered between rows of fruit trees or under the tree tray to ensure that the soil around the tree is not exposed. Generally, the thickness of grass is more than 10 cm, and more than 1000 kg of grass is planted in each orchar.
3, thin fat diligence. Timely, small amount, multiple supplements of fertilizer. Fertilizer once a month, top-dressing 30 kg of compound fertilizer or 15 kg of urea per acre.
4, disease prevention and pest control. At present, attention should be paid to the prevention and control of mites such as red spiders, aphids, and moths (Lepidoptera leaf roller, gold leaf moth) and P. caterpillars. Prevent pests and diseases to be targeted, pay attention to alternating, alternating use of different mechanisms of insecticides, fungicides, to avoid pest resistance to drug resistance.
5, outside the top dressing. After the drought, the tree's roots are damaged, and the ability to absorb fertilizer and water is weak. It is not appropriate to immediately apply root fertilizer. 0.1-0.2% of potassium dihydrogen phosphate, 0.3% urea, and high-efficiency, fast-acting foliar fertilizers can be used outside the roots. top dressing. Spray once every 5-7 days or so, spray 2 or 3 times. The organic fertilizer or urea can also be decomposed by soil to promote the growth of new roots.
