Longan is a kind of tropical fruit tree. Its excellent quality is the main fruit tree that our province vigorously develops. Because the fruit tree is rough and extensive, resulting in low yield, it is necessary to have a set of scientific management for longan yielding and stable production. How to draw autumn shoots timely is to ensure high yield. The important part of stable production. The longan has many fruits and can harvest, but the main reason for the lack of flowers is that the tipping period is not appropriate. The last shoot is often easy to germinate the winter shoots without flowering, and the shoots are not put off later because of autumn drought and temperature drop. The reason is that it is hard to get used to. Unfamiliar longan autumn shoots cannot produce flower buds due to insufficient organic nutrients stored. The following techniques can be used to promote ideal autumn shoots by drawing on comprehensive practical experience. One, because of the place, due to variety. Due to the weather that year, it was decided to put autumn shoots. It is generally suitable for germination from mid-September to mid-October, and mature at the end of December. The understanding of the fruit growers suggests that they should be released in September. Early release can be used to solve the winter shoots with early control. Early shoots are more likely to form flower bud differentiation, and there are also fruit growers. It is considered that the tipping of the tip of mid-to-late October is good, and it is believed that the winter is warm and difficult to suppress winter shoots. Each of these two methods has its own advantages. Through understanding, it is believed that the longan shoots of Dendrobium nobilis can turn green early and the shoot stage can be delayed. However, the late-maturing Ooyuan species slowly turns green, and the last shoot should be advanced. In the winter cold years, the tipping should be advanced, and the wintering should be postponed. I have learned from many years of experience that the region should be postponed for the last time, which is suitable for the winter of the region. Second, the re-application of quick-effect fertilizer: Shi slow absorption of organic fertilizer, such as chicken gizzards, pig buns, bean cakes, etc. must be applied timely after fruit picking, otherwise it will not be absorbed in time and induce smoking pumping. Short-term fertilizer application is insufficient, shoot is difficult to quickly hair, and the autumn shoots are not enough stout, the general strain 30-6 0 pounds can be applied 2-4 kg of urea, mixed half a catty of potassium fertilizer, in the vertical canopy periphery Shi, it is better to use a ring groove better, in the drought when applied to the tree plant, if not applied in the year of magnesium sulfate, zinc sulfate, borax, can be mixed into the quick-applied fertilizer application, application of fertilizer should be promoted About 15 days before the shooting period. Third, timely sparse shearing to promote the timely emergence of new shoots. Pruning should be done after fertilization. (1) Appropriately handle higher and denser branches in the middle of the canopy. Generally, 2-3 branches may be sawn off, which is conducive to better absorption of sunlight. (2) Properly remove mowed shoots, upward-producing shoots and less-leafed shoots, disease-disease branches, and over-closed branches. (3) When the fingers are 2-3 years old, they only have 2-3 tips. (4) timely sparse. After the autumn shoots sprouted, the excess shoots should be erased as soon as possible, leaving only 1-2 buds on one shoot. Fourth, in the drought, timely shower. In autumn in our province, there is always an autumn drought, soil moisture is insufficient after fertilization, fertilizer can not play a role in promoting the role of timely, therefore, in the case of long-term cultivation of longan in the mountains should not be a rain shower. V. Eradicate pests and diseases. After the longan has sprouted, it is easy to be bred by the locusts, so that the new shoots stop growing and the flower buds cannot be formed. At the same time, there are also damages such as leaf rolling, ulnar warts and caterpillars. The buds germinate and spray pest control twice. At about 2-3 cm, when the red leaves are fully opened, spray with 40% dimethoate or trichlorfon 800-1000 times can be used. For example, the larvae of the calf should be injected into the hole. Six, timely control tip. Delayed longan late autumn shoots and winter shoots for drug control. Available: Ethephon 20-30 ml + Paclobutrazol 50-100 g + Potassium dihydrogen phosphate 100 g + 50 kg water for spraying. Such as the shorter tree can be removed manually. The effect of the ethidium bismuth changes with temperature. When taking medication, the higher the temperature, the more intense the effect will be, and it will cause phytotoxicity. The ring cutting control tip, which is mainly aimed at the long-horned tree with strong tree vigor, can be cut in a circle in November and circumscribed in February and February a second time. In winter it can be combined with loose soil to control the winter shoots.
