疏果灵在柠檬上的应用效果研究

Study on the Application Effect of the Chemical "Shuguolin" on the Fruit Thinning of Lemon

[目的]研究疏果灵对柠檬的疏果效应,为其在柠檬疏果上的应用提供理论依据。[方法]以不同浓度的疏果灵处理柠檬幼果,调查不同时期不同处理的疏果效应。[结果]柠檬于4月中旬出现了生理落果高峰期。在此期间对照组的落果量大大低于喷施疏果灵的3个处理;而在这3个喷施不同浓度的疏果灵处理中,200倍液处理的落果数最多,持续落果时间最短,疏果效应最好。[结论]疏果灵对柠檬有较好的疏果效应,以200倍稀释液效果最佳。

[Objective] The effect of the chemical＂Shuguolin＂on fruit thinning of lemon was studied to provide the theoretic basis for its application on lemon.[Method] Lemon were sprayed with different concentration＂Shuguolin＂at fruit stage in spring,the effect of these treatments on fruit thinning of lemon at different periods was investigated.[Result]The peak period of physiological fruit drop of lemon happened in the middle ten days of April,the fallen fruits number of control was far below that of the three concentrations of ＂Shuguolin＂treatments in this period;among the three concentrations of ＂Shuguolin＂treatments,the fallen fruits number of 200 dilution treatment was the most,the duration of fruit dropping was the shortest,and the fruit thinning effect was the best.[Conclusion] The results indicated that chemical＂Shuguolin＂got good thinning effects on lemon,and the 200 dilution treatment was the best.
