Long eye picking after fruit picking

Longan should be adjusted from the beginning of the harvest, and the result of the mother branch is adjusted. For the two shoots, the compound fertilizer should be re-applied 10-20 days before fruit picking, 0.5-0.75 kg per plant, plus 0.2 kg of urea, and the leaves are sprayed once to increase the fruit. After harvesting, the fertilizer is applied after harvesting, and the dosage is the same as above. After the first autumn shoots, the germination fertilizer will be applied, and the fruit will be sprayed. The fruit will be sent out from late September to early October. If you plan to put a shoot on the mother's branch, apply the fruit fertilizer before harvesting, apply 1 kg of compound fertilizer per plant, and spray the fruit to increase the fruit and restore the tree. At the end of August or at the beginning of September, the germination and germination of the fruit will be applied, and the mother branch will be drawn in September. Litchi and longan are often ripe for premature autumn shoots when they encounter high temperature and wet seasons. They may send winter shoots, winter shoots sprout, and can be sprayed with chemicals. Before and after winter, the canopy is sprayed with 60-80 ml of ethephon (longan). Use 50-60 ml), add paclobutrazol 3 - 4 or phlegm 2 or 2 kg of water for 50 kg. It can also be sprayed with 2200 times of squid liquid to remove the buds of winter buds.

Second, the prevention and control of pests and diseases Litchi in the autumn leaf expansion stage, the main prevention of leaf and cockroach pests and mites, leaf curlers, cockroaches, etc., with 10% baibai 3000 times liquid or sulphide, Wanling, Dichlorvos sprayed when the autumn shoots just sprouted. Longan should be used when the summer shoots grow 8-10 cm from late June to July, and 10% chlorhexidine 2000 times or 5% card gram 1500 times liquid anti-tip moth, scorpion worm and haimai moth and lychee蝽 and 颊 颊 虱. In mid-September, the autumn shoots germinated to 8 cm, killing 3,000 times with 2.5% of the enemy or 10% of the baidu 3000 times to prevent pests such as cockroaches, mites, worms, hibiscus and lychee.

Third, after the winter fertilizer results, the mother branches are matured, and the winter ditch is digging in the ditch at the end of November and early December. Outside the canopy drip line, the total length of the tree-shaped or opposite sides is 1/4-1/2 long, and the depth of the ditch and the width of the ditch are 40 cm each. After the trenching, the roots are dried for 1 week, then Each plant is 100-200 kg of soil mixed fertilizer plus 1-2 kg of superphosphate. One kilogram of lime is mixed first, and then mixed with the excavated root soil into the ditch. The advantage is to dig some roots and prevent winter buds from occurring. The second is to force the tree to stop growing and help the flower buds to form. The third is to apply fertilizer to maintain the flower bud differentiation and flower organ growth needs, to ensure strong flowers. In addition, it is 10-15 cm deep in the tree tray, and there is a broken root to prevent the winter bud from being extracted.

Fourth, the shape of the pruning results After the mother branch is mature, a shaped winter shear is carried out around mid-December. Cut off the branches of the Yin, the weak branches, the dense branches, the cross branches, the branches of the disease, and the degree of pruning, so that at noon, the sunlight can be seen through the green leaf layer, and it is appropriate to form a large number of light spots like copper coins in the tree tray. For the new shoots, 2 to 3 sticks per branch, too much should be cut off to facilitate the flower.
