After the orchard is flooded, the soil is deprived of oxygen due to water accumulation. The roots of the fruit trees cannot be normally breathed, and the root absorption capacity is reduced, which affects the normal growth of fruit trees, and even dead trees. Therefore, after the orchard is accused, it is necessary to take timely measures to strengthen management.
First, timely drainage. Immediately after the rainstorm, the channels should be cleared, the water in the orchard should be drained as soon as possible, the drainage conditions should be improved, and the soil in the orchard should be kept dry to restore the ventilation conditions of the roots of the fruit trees. For orchards that are heavier in flooding and unable to clean up the silt in time, it is necessary to dig a drain between the rows of fruit trees to lower the water level.
Second, help the tree wash leaves. For fruit trees that are blown by the wind and washed down by water, they should be timely corrected, and the debris and leaves on the branches and leaves should be removed. It is best to spray the water with a sprayer to clean the branches and leaves to ensure the normal physiological activities of the trees.
Third, dry the tree roots. Open the soil around the tree tray to dry the roots, so that the water can evaporate as soon as possible, and then cover the soil after 3 sunny weather. On the exposed trunks and branches with 1: 10 of the whitewashed lime and straw, wheat straw dressing, in order to avoid cracking of the bark caused by sun exposure.
Fourth, cultivating the soil. When dry soil, cultivating, should seize the time, the depth can be increased, the mixed soil, clods break, generally for 1 to 2 times. Fruit trees with heavy roots and roots should be combined with cultivating soil to dry roots and remove the roots of ulcerated trees.
Fifth, timely topdressing. After the flood, all kinds of orchards can seize the favorable period of good sensation and timely topdress. The type of topdressing is mainly phosphorus and potassium fertilizer and quick-loading fertilizer. Strengthen the application of foliar fertilizer, such as spraying 0.5 % to 1 % urea solution, 0.2 % to 0.3 % potassium dihydrogen phosphate solution, and 0.1 % rare earth micro fertilizer. For the orchards with heavy flooding, after the sensation is reduced, the soil is first turned into soil and then topdressed.
