Kiwi orchard suffers from remedial measures after water damage
1. Ditch drainage. During the rain, the water will drain in time. After the water is drained, there will still be accumulated water in the low-lying areas of the park. The water shall be drained in time to restore the normal breathing of the tree.
2. Whole garden slop fertilization. After flooding, the garden floor knots cause the lack of oxygen in the root system. When the top soil of the foot is not sticky, shallow ploughing of the soil is performed to promote new roots. After loose soil, timely fertilization according to tree vigor, tree age, yield, etc., Mushi organic fertilizer from 2500 kg to 3500 kg, with Shiguoshu special fertilizer 80 to 100 kg or compound fertilizer 150 kg, depending on the size of the tree.
3. Moderate trim. To defoliate trees after the disaster, timely pruning dead branches. The whole tree cut dead branches, branches and branches, cross branches, dense branches, and delicate branches, so that the trees were airy and light and the metabolism was balanced.
4. The trunk is painted white. After the fall, it is easy to fall leaves, and the trunk can be coated with white, whitening agent formula: 10 parts of water, 2 parts of quicklime, 0.5 parts of salt, 1 part of solid lime sulfur, or 25 grams of sulfur powder.
5. Spray foliar fertilizer to strengthen the nutrient of the tree and speed up the restoration of tree vigor. Can use 0.2% urea + 0.5% potassium dihydrogen phosphate, foliar spray, once every other week, 2-3 times in a row.
6. Prevent disease. After the accumulation of water, it is prone to diseases, and 800 times of carbendazim or 1,000 times of thiophanate-methyl is sprayed on the leaves to control the breeding of pathogens and avoid further damage to the health of fruit trees.
7. After flooding, spray the active oxygen scavenger as soon as possible under the weather permitting to alleviate the damage. Use 1000ppm sodium benzoate or ascorbic acid (reactive oxygen scavenger) to spray the foliage.
