Sapling prune. The long spring shoots are short, retaining 6-8 leaves; the medium spring shoots cut off the top one or two leaves, and the short spring shoots ignore. If there is fruit on the tree, remove it. Fertilization. Before the germination of the summer shoots, the roots are applied once to make the Jia + Jia Shimei balanced water-soluble fertilizer, promote the spring shoots to mature and promote the summer shoots; the summer shoots come out and then pour a Shierkang + roots to make Jia + Jia Shimei high potassium Type water soluble fertilizer. Wipe the tip and shampoo. Orange gardens with sporadic summer shoots should be erased once or twice, and then unified to shoot; the summer shoots that are born inward should be properly removed. Pest Control. During this period, it is necessary to prevent pests such as red spiders, hibiscus, leaf miner, aphids, and thrips, and diseases such as anthracnose and ulcer disease: the agents may be selected from avermectin, mancozeb, thiacloprid, etc. It can be combined with foliar fertilizer at the same time. Hanging fruit tree Stabilize fruit fertilizer. Fertilization of fruit trees in young fruit period is the key to tree potential, spring maturing, flowering and fruit. Fruits with few shoots and general trees, leaching the roots to make Jia + Jia Shimei balance type, roots and roots, supplement Xiehua and fruit drop to consume nutrients, and strengthen the tree. Plants with moderate amount of fruit and strong tree strength, drenched with Shimei high potassium or flower and fruit experts, promote fruit enlargement, size and fruit, and inhibit the germination of summer shoots. Spray the second fruit-preserving medicine in time. The second physiological fruit drop of citrus is mainly due to the lack of essential nutrients in the development of young fruit, resulting in dysplasia, so that the young fruit does not have fruit detachment. Young fruit development and shedding are supplemented by nutrients and need to be supplemented according to different growth periods. In the second fruit drop period to the stable fruit period, more potassium and calcium are needed, and the flower fruit expert + the beautiful red crown calcium or the red color compound sugar chelated calcium magnesium can be sprayed. Ring cut fruit. The ring cutting is mainly aimed at plants with strong tree growth and strong vegetative growth. At the same time, for the initial fruit tree, the tree can improve the ability of regulating the nutrition of the tree and cultivate the "habit" of the tree. In general, the prosperous trees with fewer flowers and fruits are cut early and cut more, focusing on regulating the supply of young fruits to the tree; the fruit is more strong, cut later, and the young fruit should be lightly cut after turning green. Or not cut, to ensure that the young fruit gets the supply of root fertilizer. Pay attention to abnormal weather. Do the drainage work of the orchard in the rainy weather to avoid the accumulation of water after the rain affects the root growth and causes the fruit drop. High temperature and dry weather need timely irrigation and moisturizing, supplementing the new year's red leaf fertilizer to improve the resistance of the tree: high temperature and drought will affect the absorption of fertilizer and water and the growth of young fruit, causing abnormal fruit drop. Control the summer shoots. The period should be mastered in the middle of May (the spring shoots before the ripening - the early stage of the summer shoots). Main pest control. The main pests and diseases in the young fruit period: anthrax, scab, brown spot disease and other harmful branches, young fruit caused by fruit drop; red spider, malignant leaf aphid, aphid, hibiscus and other hazards affect the quality of spring shoots and spread germs.
