摘要
[目的]解决当前郁闭荔枝园郁闭程度较高、通风透光不良、管理难、病虫害严重、产量低和品质差等问题，提高荔枝产品数量与质量。[方法]于2008—2014年在深圳石岩果场，以糯米糍品种为供试材料，研究回缩及间伐技术对郁闭荔枝园的影响。[结果]间伐园产量趋于稳定，树体生长发育状况良好，果实品质提高，病虫害发生率明显降低，综合经济效益增加。[结论]郁闭园经过改造后产量与效益可显著提高。
Abstract
Objective] To solve the problems of relatively high litchi enclosed degree, poor aeration and photopenetration, difficult manage-ment, serious plant diseases and insect pests, low yield and poor quality, to enhance the quantity and quality of litchi.[ Method] With Nuomici variety as the test materials, we researched the effects of intermediate cuttings and retraction technology on litchi enclosed orchard. [Result] The yield of thinned orchard became stable.Tree growth and development showed good status; the fruit quality enhanced; and the incidence of plant diseases and insect pests significantly reduced; the overall economic efficiency increased.[ Conclusion] Enclosed orchard can significantly enhance the yield and benefit after transformation.
