不同处理对红肉蜜柚成花与坐果的影响

针对广西红肉蜜柚存在的花少、产量低等问题，本试验在广西容县比较了叶面喷施多效唑、2，4－D与GA3、环割、环扎等处理对红肉蜜柚成花与坐果的影响。结果表明，施用多效唑、环割、环扎均可以显著或者极显著地促进红肉蜜柚的成花。在第一次生理落果结束后叶面喷施20 mg/L GA3+12 mg/L 2，4－D 1次或在第一次生理落果结束后叶面喷施20 mg/L GA3一次可极显著提高红肉蜜柚保果率。

Effects of different treatments on Flower formation and Fruit setting of Red Pulp Pomelo

In view of the problems of few flowers and low yield of red pulp honey pomelo in Guangxi, the effects of foliar spraying paclobutrazol, 2, 4-D and GA3, ring cutting and encircling on flower formation and fruit setting of red meat honey pomelo were compared in Rongxian, Guangxi. The results showed that paclobutrazol, circumcision, and cerclage can all significantly or very significantly promote the flower formation of red pulp honey pomelo. The flower amount was significantly increased by encircling in the middle of September or spraying 15% paclobutrazol wettable powder 400 times once and cut 2 times in the upper ring of the trunk in the middle of September or 2 times in the middle of September. Spraying 20 mg/L GA3+12 mg/L 2, 4-D solution once after the first physiological fruit drop or 20 mg/L GA3 solution once after the first physiological fruit drop could significantly increase the fruit preservation rate of red pulp honey pomelo.
