| 摘 要： | 报道了6个处理：A、花蕾直径3～5mm时疏花序；B、第一次生理落果结束后，在果实横径0．5～1．0cm时疏果；C、A＋B；D、第一次生理落果结束后，果实横径2～3cm时疏果；E、不疏蕾不疏花，第二次生理落果结束后、果实横径3～5cm时疏果；CK、不疏蕾和花、不疏果，只疏畸形果、病虫果，对沙田柚坐果率、产量和商品果率的影响。结果表明，除处理B比D、CK显著提高坐果率，处理D、E显著提高商品果率以外，其它各处理间及各处理与CK间的坐果率、株产量与商品果率无显著差异。因此沙田柚的疏果宜在第一次生理落果结束后、果实横径约0．5～1．0cm时进行。

| Abstract: | The influence of 6 kinds of thinning treatment on the percentage of fruit fertilizing,output and the rate of commodity fruit of Shatian pomelo was tested.The treatments were A:thinning anthotaxy when the diameter of the alabastrum is between 3-5mm;B:thinning fruit when the diameter of the fruit is between 510mm after the first period of physiologic drop;C:A+B;D:thinning the fruit when the diameter of the fruit is between 20-30mm after the first period of physiologic drop;E: thinning fruit when the diameter of the fruit is between 30-50mm after the second period of physiologic drop without alabastrum and anthotaxy thinning;F(CK): thinning the abnormal fruit and the fruit with disease only(as check experiment).The results indicated that except for the remarkable improvement in the percentage of fruit fertilizing with treatment B,comparing with treatment D and F,and the rate of commodity fruit with treatment D and E,there were no significant differences among the rest of the treatments.Therefore,the suitable time for fruit thinning of Shatian pomelo is when the diameter of the fruit is between 5-10mm after the first period of physiologic drop. |
