【Abstract】 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%.更多还原
