The key to the post-harvest management of fruits in the coming year is the key
Many fruit growers do not pay attention to post-harvest management after harvesting the sheds, and are still performing extensive management. As a result, the production of grapes in the following year has been reduced by 10% to 20%. Experts on mixed fruit point out that the fine management of grapes after harvest must grasp the “four elements†in order to achieve a multiplier effect.
Combined with actual fruit after good fruiting. After the fruit is harvested, it is crucial to supplement the nutrition and restore the tree vigor. After the fruit is applied, the fertilizer can play an important regulatory role. After the fruit is applied, the fertilizer should be fertilized according to the standard of the plant, and apply about 12 kg of fast-acting nitrogen fertilizer per acre, spray 0.3% urea, spray 2~3 times continuously to restore normal growth. If the tree grows vigorously, use it sparingly to prevent the new shooter from being long.
Cultivated grass timely clean garden. If drought occurs continuously for 15 to 20 days, furrow irrigation should be conducted in a timely manner to keep the field holding water no less than 60%. In addition, timely clean up of the orchard should be carried out in a timely manner. The diseased shoots, diseased leaves, diseased fruit, dead branches, and debris should be promptly brought out of the park to be buried or burned in a timely manner in order to reduce the source of diseases and pests, and then spray the entire garden. "General Tree Guard" sterilizes and prevents overwintering viruses from spreading.
Continue to focus on pest control. After the fruit is harvested, the fruit trees are susceptible to fungi, downy mildew, black pox, rust, etc., especially in rainy years, so after the grapes are harvested, they must continue to grasp the prevention and treatment of diseases. Disease prevention and control can use the "new high fat film + fungicides + insecticide" solution mixed use to enhance efficacy. Choose pesticides as low-toxicity and pollution-free pesticides as possible to avoid long-term residues of pesticides. In addition, we must strictly guard against the damage of beetles such as beetles, hornworms, and two-leaf beetles.
Finely trim the tree. It is especially important to carefully trim the grapes after fruit picking and to make the tree shape well. Pruning should first do a good heartpatch, try to remove tendrils and thin branches, remove severely damaged leaves, in order to reduce nutrient consumption, adjust the flow of tree nutrients, and promote the full maturity of bud eyes. The second is to do a good job of supporting the three branches of the resulting branches, vegetative branches and renewed branches, and to deal with the unplanned secondary results in a timely manner. After the fruit tree is trimmed to protect the wound, the oil can be used to “cure the anti-corrosion film†to close the wound in time to prevent the bacteria from infecting the wound, thereby protecting the wound from healing.
