| 摘 要： | 利用石硫合剂、乙烯利和萘乙酸进行了芦笋疏花疏果效应试验。结果表明:3种药剂均显著降低了芦笋坐果率,其中以0.1%萘乙酸效果最好,坐果率只有24%,且无药害发生。3种药剂在高浓度下对芦笋也有一定的疏花效应,其中0.8%乙烯利疏花效应最大,落花率为22.2%。

| Abstract: | Effect of Ethephon,lime-sulphur and naphthylacetic acid on flower and fruit thinning were studied in this experiment.The results showed that 3 chemicals all decreased fruit setting rate significantly.0.1%NAA had the best fruit thinning effect with 24%fruit setting rate and no phytotoxicity to the plant.The 3 chemicals also had flower thinning effect on asparagus,and 0.8%Ethephon had the highest flower dropping rate of 22.2%. |
