Orchard Management After Floods
During the flood season, the roots of the fruit trees are in a state of flooding for a long time, which may result in bad rooting due to poor ventilation, affecting the normal growth of fruit trees, and even the phenomenon of dead trees. Therefore, in summer and autumn, especially when there is continuous rain and rain, it is of utmost importance to promptly drain and manage orchards. Timely drainage of lighter orchards in flooding, after the rain to clear channels, discharge of water from the orchard, and clear the mud within 1 meter around the tree tray out of the park, in order to maintain the normal respiratory metabolism of the tree; severely flooded branches To cut off in time, to leaves to fruit, to reduce the amount of transpiration, and to clear the deciduous fruit in the orchard; the flooding of heavy or short time can not timely clean up the silt of the orchard, dug in the fruit trees between the ditch to reduce the water table To maintain maximum ventilation in the orchard soil. Dry the roots of the tree and dry the roots around the tree plate to allow the water to evaporate as soon as possible. After 3 sunny days, cover the soil. Exposed trunks and branches were whitewashed with 1:10 lime water and wrapped with rice straw and wheat straw to avoid cracking of the bark caused by sun exposure. When cultivating sun soil when the soil is dry, it should be time to cultivator. Increase the depth of the cultivator appropriately, mix the soil and crush the soil blocks. According to the specific conditions of soil and fruit tree growth, cultivating 1 or 2 times. After the top soil is dry, the soil is plowed. The depth of cultivating in the dry land is 25 to 30 cm, and the depth of cultivating in the water is 20 to 25 cm. Apply 0.2%-0.4% of potassium dihydrogen phosphate to the orchard with fruit after applying fertilizer on the leaves to promote coloration and improve fruit quality; apply 0.5% to the unfruitful orchard Urea solution to enhance the light and effect, increase the tree's nutrient accumulation. Early application of basal all kinds of orchards to seize the favorable conditions of soil moisture, early application of organic fertilizer based basal. After the flooded orchard is reduced, the deep orchard is first deep-rooted, then the base fertilizer is applied. Strengthen pest control First, rapid spraying control. Spray a highly effective fungicide immediately after the rain, such as 70% of the carton, M-45, etc., to control the growth of various types of germs. The second is to strengthen the management of bagging apple orchards, especially in apple orchards where black spot disease occurs more severely. The ventilation holes in the bottom corners of large bags should be cut and bags should be removed timely. After removing the bag, timely spray a high-efficiency bactericide. Strengthen pre-harvest management to pick up leaves and fruit in a timely manner, and conditional orchards promote retroreflective coatings to increase the degree of fruit coloring. Timely harvesting requires early harvest of orchards that have been inundated for a long time; harvested orchards that are lighter or unaffected should be harvested in stages; and late-maturing varieties should not be harvested as early as possible so as to avoid falling prices due to centralized listing.
