眼下正是南方地区荔枝、龙眼秋稍生长的黄金季节。众所周知,培养良好秋梢结果母枝为明年丰产优质打下坚实的基础,是丰产的关键。为实现这一目标,除加强土、肥、水管理外,做好防治病虫害是重要一环。由于近年来各地荔枝、龙眼幼龄投产果园面积不断增加,而对于初投产树、青壮年结果树,要培养适时秋梢,以放两次秋稍为宜,部分肥水丰足的还可以放三次;又因去年冬季受寒害影响,致使今年有许多果园空怀无果,养分消耗不多,这部分树为避免抽发冬稍多数也要放两次秋稍。梢次愈多,意味着害虫食物链延伸,增加病虫防治工作量,而8-10月往往高温伴随干旱,是多种害虫高发期。因此,应引起重视,切实作好秋稍期病虫防治,保护新稍。 Right now it is the litchi in the south, longan autumn grow slightly golden season. As we all know, the cultivation of good results shoot autumn branches for the next year to lay a solid foundation for high yield and quality, is the key to high yield. To achieve this goal, in addition to strengthening soil, fertilizer and water management, preventing and controlling pests and diseases is an important part. As in recent years, litchi, longan orchard put into operation the area of ​​young growing, but for the initial production of trees, young trees, to cultivate timely autumn shoots, to put two autumn slightly appropriate, plenty of fertilizer can also be placed three times; As a result of last winter’s chill injury, many orchards were left vacant this year with low nutrient consumption. This part of the tree has to be replaced by a little autumn in order to avoid taking a little more winter. The more shoots, which means that the extension of the pest food chain, increase the workload of pest control, and 8-10 months often accompanied by high temperatures, drought is a variety of pests high incidence period. Therefore, we should pay attention to earnestly make the pest control in autumn and protect the new ones slightly.
