Know the management measures of large cherry after harvest
Fertilizer and water management The top cherries should be topdressed in time after harvesting. Common methods for top dressing after harvesting are furrow application of decomposed manure and urine, application of compound fertilizer and foliar spray fertilizer. Results For large trees, 30-50 kg or 2 ~ 3 kg of rotted bean cake or 1 kg of chloride, nitrogen-free, phosphorus and potassium multi-component compound fertilizers were generally applied per plant. Ditch application was adopted, and the depth of the ditch was 20-40 cm. And irrigate. Foliar top dressing was carried out from July to September. Every 15 days or so, the leaves are sprayed with various foliar fertilizers or 0.3% urea + 0.3% potassium dihydrogen phosphate or 800 times Taibao 2-3 times. Plastic pruning Large cherries in summer should be pruned immediately after fruit picking. The main technical measures are sparse branching, topping, twisting, pulling branches, etc., using summer pruning to weaken the competitive branches, adjust the ventilation and light transmission level in the canopy, increase the amount of fruiting branches and nutrient storage, prevent the fruiting parts from moving outward, and promote the differentiation of flower buds. Thinning is mainly carried out after fruit picking. For some trees with canopy closure and poor ventilation conditions, it is mainly to remove overdense branches to solve the wind and light conditions in the canopy; for the upright strength that seriously affects the wind and light conditions in the crown Prosperous branches should be removed from the base; backbone branches and perennial branches around the crown should also be removed from the base. Twisted tips are 5 to 6 leaf buds at the base of the branch on the back, twist the branches 180 degrees with the thumb or index finger, the branches are inclined downward, to prevent them from standing up again, and promote the formation of flower buds. Pulling the branches and opening the corners is the most effective way to ease the tree vigor, promote short- and medium-term fruiting, and promote the differentiation of flower buds. The base angle of the large cherry branch is small, and the opening angle of the branch must be carried out as soon as possible. Pest and disease control For brown spot perforation and bacterial perforation, spray 70% Inodo · Manganese Zinc 600 times or Dingquat 1500 times at intervals of 15-20 days; prevention of gum disease can be combined with leaf control after fruit picking For diseases, spray 4,000 times of 40% fluosilazole EC 2 to 3 times. For dry rot disease, a longitudinal knife should be used, and then apply 5 to 10 times the enemy of bacteria or 30 times Nongfengling. Large cherry insect pest control: red and white spiders can be controlled by 10% mite chopping 1500 times or 40% cable beads 2000 times; Peach leaf moths, when larvae damage leaves or adults, immediately spray chlorchloruron 2000, 15 to 20 days apart, 2 consecutive sprays; Red-necked beetle, using the habit of adults resting on branches at noon, to carry out artificial killing, when fresh insect feces are found at the entrance of the hole, artificially dig the insect or worm into the hole 20 Chlorpyrifos.
