First, the application of organic fertilizer persimmon requires a larger amount of fertilizer, application of organic fertilizer can be strong tree vigor, increase resistance, improve fruit quality. Basal fertilizer is usually applied well before harvesting. At this time, the leaves have stopped growing and the fruits have entered the coloring stage. The roots are at the later stage of growth, which is conducive to nutrient absorption and increases the organic nutrient accumulation of the tree, which can increase the tree potential and increase the The cold resistance of the tree can also promote flower bud differentiation, laying a foundation for the next year's high yield. Apply water promptly after fertilization.
Second, proper pruning improper trimming (heavy or too light) is likely to cause persimmon flow plastic, falling flowers and falling fruit, growth period should pay attention to trim work. During the growing period, the dense branches and ineffective branches are sparsely left, and the branches are kept on the windward side, which can play a role in preventing winds. On the leeward side, few branches are left, which promotes ventilation and light transmission, so that various parts of the tree can be reasonably distributed. Ensure that the proportion of leaf and fruit is appropriate and that the balance between reproductive growth and vegetative growth can effectively prevent flowering and fruit drop. Care must be taken when pruning to apply a “wound and anti-corrosion film†to the resulting wound to promote early healing of the wound and to prevent pests and diseases from intruding into the tree.
3. Do a good job of clearing the kaki gardens after harvesting the fruits of the clear gardens to reduce the occurrence of pests and diseases and strengthen the trees. Remove the remaining litter and diseased fruits in the orchard, and bring them out of the park to be destroyed; remove the dead branches, remove the residual pedicles, combine the pruning, remove the diseased branches, insect buds, and pests; thoroughly scrape off the branches and rough skin for the branches. Insect pests and diseases, after the scraping of the diseased skin, apply the “General Tree Guard†to suppress the re-infestation of pests and diseases.
4. Insulation and anti-freeze Into autumn and winter seasons, the weather gradually turns cold. At this time, the metabolism of the persimmon tree is relatively slow, and its vitality is weak, and it is prone to frost damage. It can spray "new high-fat film" emulsion, effectively protect persimmon cold and frost, as well as disease prevention, anti-corrosion, inhibit the proliferation of bacteria.
