How to manage kiwifruit in summer?

How to manage kiwifruit in summer? Please introduce that summer is not only the key period for kiwifruit growth, but also the key period for the formation of fruit quality. Management should pay close attention to tree management, adjust the contradiction between vegetative growth and reproductive growth, and promote the formation of fruit quality. Strict thinning of fruit. From 15 days after falling flower to 3 times of fine fruit thinning before bagging, according to the principle of "leaving the good to remove the bad, the big to the small, the sparse to dense, and the middle to the base", remove the round fruit, abnormal fruit or weak small fruit, overlapping fruit, disease and insect fruit and so on. Generally, there are 4 or 6 long fruit branches, 2 or 3 moderate fruit branches, and 1 short fruit branch or no fruit. There were no more than 400 fruits per plant in the orchard with row spacing of 3 m × 4 m, and no more than 200 fruits per plant in the orchard with row spacing of 2 m × 3 m. Wipe the buds and pick the heart. According to the growth characteristics of rhesus monkeys, early sprouting, timely coring, long branches and short pruning should be taken and pruned many times. In the sprouting stage, the incorrectly positioned or dense buds can be erased early; for the exuberant fruiting branches of the adult orchard, leave 7 leaves above the fruiting part to pick the heart, and leave 3 leaves and 4 leaves for the second branch after the first pick. 2-3 leaves were left for the third germinating branch, and l0~l2 leaves were left for the culturable shoot or vegetative branch, and the disease and insect branches and slender branches were removed from the base. Pull branches and tie vines. From the end of pruning in the previous winter to the period of fruit expansion, the fruit branches and vegetative branches should be stretched evenly and bound repeatedly, and the strong skeleton branches should be rubbed and softened and then bound, generally 1 or 2 times, and tied to the wire with a binding rope. Strengthen the management of fertilizer and water. Fertilization in summer should be applied a small amount for many times, in principle, high concentration chemical fertilizer should be avoided, and ammonium fertilizer should be prohibited. At the beginning of June, the expanded fertilizer plant applied 1 kg of three-element compound fertilizer, 0.5 kg of medium and trace element fertilizer, and 0.5 kg of potash fertilizer at the end of July and the beginning of August. The amount of fertilizer applied in the first hanging orchard should be reduced. The position of fertilization is 80cm from the trunk and the depth of fertilization is 15cm and 20cm. Fill with water after each fertilization. After bagging, 1:1 times biogas liquid or amino acid nutritious leaf fertilizer was sprayed every 10 days for 3 times. In case of high temperature and drought, irrigation should be made before 11:00 or after 4pm when the ground temperature is low. Fruit bagging. Generally use 12 cm × 16 cm single-layer paper bag. Bagging time: Hongyang in mid-late June. Jinyang and Xu Xiang in early and mid-July, and Hayward from mid-July to early August. Set the fruit strictly before bagging and spray once highly effective insecticide and calcium fertilizer. Pest control. Agricultural, physical and chemical comprehensive control measures were adopted, and pesticides from plant sources, mineral sources and biological sources were selected with high efficiency, low toxicity and low residue. From June to August, 80% of Dasheng M45 wettable powder 800 times or 50% methyl thiophanate 600 times 800 times or 1% of Zhongshengmycin 200 times solution were sprayed after bagging, focusing on the prevention and control of soft rot, brown spot and so on.
