摘　　要：针对广西阳朔县沙田柚的单产、果实可溶性固形物含量、商品果率低等问题进行调查研究，总结出沙田柚低产的主要原因，提出并实施了合理修剪，培育质优量足的结果母枝，调控花芽分化，花期进行人工异花授粉，合理追肥、排灌和疏果，夏季深施重肥，实行果实套袋，综合防治病虫害等综合治理措施，2001-2005年累计推广应用2026hm^2，取得了平均单产28378kg／hm^2，果实可溶性固形物含量12．0％，商品果率96．09％的增产及改善品质的效果。The existing problems of Shantianyou pomelo production in Yangshuo of Guangxi, including low yield, low soluble-solids content and low commodity rate, etc. were investigated, and main reasons of low-yield of Shantianyou pomelo concluded. Through comprehensively controlled measures including reasonable pruning and breeding high-bearing rate branches, regulating the flower bud differentiation and applying artificial cross pollination at florescence, carrying out reasonable fertilizing, drainage and irrigation, and fruit thinning, deep fertilizing high rate fertilizer in summer, bagging fruits, and integrated controlling diseases and pests, etc. , the effects on increasing the yield and improving the quality were obviously. The technique extending and applying area reached 2,026 hm^2 and the unit yield was 28,378kg/hm^2, the soluble-solids content was 12.0%, and the commodity rate was 96. 09%.
