Management Methods and Planting Key Points for Cherry Trees After Picking
How should cherry trees be managed after picking? Please provide a detailed introduction. After picking cherries, the following methods can be used for management: 1. Fertilize cherry trees in time and apply basal fertilizer early: After cherry harvest, the trees urgently need nutrient supplementation, so quick-acting multi-element compound fertilizer should be applied in time. Generally, depending on the tree age and tree size, apply 1... per tree.
How should cherry trees be managed after picking? Please provide a detailed introduction.After picking cherries, the following methods can be used for management:
1. Fertilize cherry trees in time and apply basal fertilizer early:
After cherry harvest, the trees urgently need nutrient supplementation, so quick-acting multi-element compound fertilizer should be applied in time. Generally, depending on the tree age and tree size, apply 1.0-1.5 kg of compound fertilizer per tree; for weak-growing trees, add 0.15-0.25 kg of urea per tree.
To restore the tree's growth vigor as quickly as possible, foliar spraying of 0.3% potassium dihydrogen phosphate solution can also be done. In order to improve the tree's stored nutrient level and ensure the supply of nutrients needed in the early stage of tree growth next year, basal fertilizer should be applied early in early September. The basal fertilizer should mainly be attached organic fertilizer, applied at 3000-4000 kg per mu.
2. Prevent drought and waterlogging disasters in the cherry orchard:
After cherry harvest, in order to restore the tree's growth vigor and promote flower bud differentiation, in addition to strengthening topdressing, timely irrigation should be carried out during dry weather to ensure water supply, and attention should be paid to preserving soil moisture so the trees do not suffer from drought.
In July-August, it is the rainy season. If the orchard's drainage conditions are poor, especially if the orchard soil is clay with poor water permeability, or if the soil layer is relatively thin and the terrain is mountainous land with waterlogging on one side, drainage ditches should be dug in advance, and when rainlogging occurs, accumulated water should be drained in time.
3. Carry out summer pruning in the cherry orchard, but winter pruning should be late:
After fruit harvest, varieties that tend to rebound vigorously in growth (such as Hongdeng) and some plants with low fruit set rates and relatively vigorous growth are prone to canopy closure and poor ventilation and light penetration.
Therefore, summer pruning should be carried out during the rapid growth period after fruit harvest, mainly by pinching to control vigorous shoot growth, and by thinning overlapping branches, crossing branches, competing branches on the outer canopy, and other densely crowded branches. For scaffold branches with unopened angles, branch bending to open the angle should be done in late September.
4. Timely prevent and control cherry tree pests and diseases, and prevent early defoliation:
For cherry trees after fruit harvest, if cherry brown spot perforation disease or cherry bacterial perforation disease occurs, spray 80% Daconil M-45 or Spyrk 600-800 times solution 2-3 times.
To control mite pests, spray 75% Propargite 2000 times solution; to control peach leafminer moth, spray 25% diflubenzuron 1500-2000 times solution; to control pear lace bug, spray 2.5% deltamethrin 3000 times solution.
