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2026hm2,取得了平均单产28378kg/hm2,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。
In order to investigate the main reasons for the low yield of Shatian pomelo, this paper put forward and implemented a reasonable pruning method to cultivate the fruit of high yield and good quality for the purpose of investigating the yield, fruit soluble solid content and fruit yield of Shatian pomelo in Yangshuo County of Guangxi. , Control flower bud differentiation, flowering artificial cross-pollination, rational topdressing, irrigation and thinning irrigation, heavy summer fertilizer, the implementation of fruit bagging, comprehensive prevention and control of pests and diseases and other integrated measures, from 2001 to 2005 the cumulative promotion of the use of 2026hm2, made The average yield of 28378kg / hm2, fruit soluble solids content of 12.0%, the commercial fruit rate of 96.09% yield and improve quality results.
