龙眼一、物候期‘秋梢抽生长期。二、中心工作:修剪、促梢。三、主要病虫害:卷叶蛾、毒蛾、佩夜蛾、亥麦蛾、尖细蛾。四、相关技术措施:1、采果后第一次秋梢开始老熟,准备抽第二次秋捎,一般尽量减少氨肥的施用量,树势旺,长势良好的可不施肥,但要用卢博士2号肥30毫升兑水喷施叶面2～3次,隔7～10天喷一次。促进枝梢尽快抽生,并在12月初老熟。2、对树势弱的,应株施粪水(沼气液)50～80斤加卢博士1号肥30毫升,促使第二次梢抽生,同时加强叶面肥的喷施。3、第一次秋梢还没有疏好芽的,应继续疏芽,除去内膛枝,方法是0.6厘米的枝条留1条芽,0.8～1厘米以上的,视其生长空间可留2条,其余抹除。4、遇上秋旱要及时淋水。5、病虫害防治应采取“一梢三药”的方法,即梢长5厘米和展红叶转淡绿时用20%果虫一扫光15毫升加敌敌畏10毫升兑水30斤各喷一次。(覃立翔)
Longan one, phenophase ’autumn shoot pumping long-term. Second, the center of work: pruning, promote shoots. Third, the main pests and diseases: leaf roller moths, poison moth, paternity moth, hawk moth, tip moth. Fourth, the relevant technical measures: 1, after picking the first autumn tip began to mature, ready to take a second autumn along, generally minimize the amount of ammonia fertilizer application, vigor tree vigor, good growth may not be fertilized, but to use Dr. Lu 2 fertilizer 30 ml watered foliar spray 2 to 3 times, spray every 7 to 10 days. Promote shoots pumping as soon as possible, and in early December mature. 2, the tree is weak, should be Shi Shi manure (biogas) 50 ~ 80 kg Dr. Gallup No. 1 fertilizer 30 ml, prompting the second shoot pumping students, while strengthening the spraying of foliar fertilizer. 3, the first autumn tip has not sparse bud, should continue sparse buds, remove the inner branch, the method is 0.6 cm branches leave a bud, 0.8 ~ 1 cm above, depending on their growth space can stay 2 , The rest erased. 4, in case of autumn drought to timely watering. 5, prevention and treatment of pests and diseases should take the “one shoot three drugs” approach, that shoot long 5 cm and red leaves turn green when the flowers with 20% swept away the light insect 15 ml plus dichlorvos 10 ml watered 30 kg each spray once.
