July-August is the post-harvest management of mangoes. Management of mango trees after harvest is directly related to mango production in the coming year and must be strengthened.
The main management measures include pruning, fertilizing, and preventing and controlling diseases and insect pests. In the second year, normal flowering results can cultivate robust autumn shoots.
1, fertilization. The principle of fertilization is: more and weaker trees should be applied more and nitrogen fertilizer should be combined with phosphorus and potassium fertilizers. The trees with less results and prosperous growth should use less phosphorus and potash fertilizers, and nitrogen fertilizer should be used less. After fruit picking, the main attack autumn shoots, its fertilization amount is about 40% of the year, the fertilizer is mainly fast-acting fertilizer, early maturing varieties are finished before the end of July, and the mid-late-maturing varieties are finished before the end of August. When fertilizing, minimize rooting.
2, trim. Immediately after the harvest, the main pests were sparse, dense branches, diseased branches and dead branches. As a result, more trees need to leave more leaves and cut lightly. Trees with little or no result should be thinned or retracted according to the dense crown. Weak trees are not pruned except for dead branches and pests, and management should be strengthened to promote more branches. Orchards should pay attention to drainage work.
3, control pests. At present, the main pests and diseases include: anthrax, coal smoke, liquid plastic disease, tawny scorpion, leafhopper, poisonous mites, beetles, aphids, white moth, wax cockroaches, and scale insects. Prevent disease with a new high-fat membrane or carbendazim or thiophanate-methyl 700-800 times the liquid, spraying 1-2 times in the new shoot; new shoots about 3 cm, the available 800 times Trichlorfon control Spodoptera litura , poison moths, chafers, once every 7-10 days, once per shoot phase, and leafhoppers, aphids, white moth, wax cockroaches, insects, etc. can be used imidacloprid 1500 times plus 800 times liquid trichlorfon spray. Bituminous coal disease is mainly controlled by preventing the occurrence of leafhoppers and aphids. (China Plant Protection Network: Li Ruifeng)
Same as round type LED Surgical Lamp, the flower type operating lamp also can add camera system, the camera system can choose SD or HD, depends on hospital requirment, even though single dome or double dome, both can add camera system, can choose camera built in or built out. The camera system is Sony brand, we have use it for many years, the system is stable. as recording and teaching is part of Cuntinous Medical Education (C.M.E) within and outside the O.R/ Hospital, our solution is to achieve both. The image resolution of full HD medical grade digital camera can be as high as 1920*1080 pixels.
