在夏梢初发时,对幼龄的“尾张”品种柑桔树,全株喷250-500ppm 调节膦,22天后,控梢率达70-80%,37天时为40-45%,与对照株比较,夏梢长度平均短二分之一以上,全株夏梢干物质量减轻85-90%。座果率明显提高,增产效果显著,对品质影响不大。1000ppm调节媵对柑桔有药害,表现为叶片卷曲,座果率降低,果重减轻。同样方法使用2000ppm B_9和3000ppm 健壮素也有抑制柑桔夏梢生长的作用,但持续时间不长。2000ppmCCC 抑制夏梢的效果不明显。B_9健壮素、CCC 等处理对果重均无影响,其中健壮素对座果率有所提高,B_9,CCC 对座果率影响不大。
At the beginning of summer shoots, the citrus tree of young “Mei Zhang” was sprayed with 250-500ppm of whole plant to adjust phosphine. After 22 days, the rate of shoots reached 70-80%, 40-45% at 37 days, Compared with the control, the average length of summer shoots was shorter than half, and the dry weight of whole plant was 85-90%. Fruit rate significantly increased yield significant effect, little impact on the quality. 1000ppm regulation 有 on the citrus have phytotoxicity, manifested as leaf curling, reduced fruit set, fruit weight reduced. The same method using 2000ppm B_9 and 3000ppm Jianshuang also inhibit the growth of summer orange tip, but the duration is not long. 2000ppmCCC inhibit summer tip effect is not obvious. B_9, CK and CCC had no effect on the fruit weight, among which, the hormone of KCl increased the percentage of fruit set, B_9 and CCC had little effect on the fruit set percentage.
