Fertilization is the season with the largest amount of pumping in spring. The quality and quantity of shoots directly affect the output of the year. Therefore, fertilizer must be applied. Saplings each apply about 0.1 to 0.3 kg of urea, mature trees need to apply 2/3 of the annual fertilization amount, about 0.8 to 1.5 kg, three times a rainy day. The first is to apply good spring fertilizer, especially if it is not enough to go to winter base fertilizer. The spring fertilizer must use enough, and the amount is generally 2 to 2.5 kg of compound fertilizer per plant.
Patching Due to the effects of rain and snow last winter, some farmers have rushed to prune, leaving too many branches left, and the pruning of pests and branches too short. Therefore, we must pay close attention to complete this management link before the injury and timely clear the branches out of the orchard. At present, low-altitude areas of pruning have been delayed. Injurious flow will occur during pruning. At this time, wound healing should be used to seal wounds to prevent injury. General tree protection should be used to disinfect the trees with 800 trees, and the general tree-keeping force has strong puncture power. It can be used to break up the condensate in the fruit tree, clear the benign guidance of nutrients, heal and tear the catheter, and prevent the kiwifruit's wound flow. High-altitude kiwifruit pruning is not in place, and when trimming, the amount of mother trees should be kept reasonably.
Pest control Prevent the timely eradication of eggs and lesions on trunks and vines. The resulting wounds should be promptly treated with anti-corrosion film to protect the growth of wound healing tissue, infestation with decay-resistant rot, protection of soil, rain pollution, and prevention of chapped wounds. To reduce the occurrence of pests and diseases in the future.
Plastic tying is also an important task in the management of kiwi trees in spring. The requirements for primary and secondary kinks are clearly defined. First, it is necessary to choose good branches as the main branch. Second, the vines should be evenly distributed, which is conducive to the growth of branches.
