为了抑制幼龄温州蜜柑夏梢的生长,从而减少六月落果,应用一种高效的植物生长抑制剂—调节膦(氨基乙基甲酰磷酸酯铵盐),于夏梢发生前叶面喷洒,浓度为250～1000ppm。试验结果表明;3年生“宫川”的夏梢发生率为对照的7.4～18.8％;6年生“尾张”为15.8～28.1％,枝条缩短,节间密。当夏梢长度在1.5厘米以内喷洒,则3年生“宫川”夏梢发生率为对照的5.3～7.4％,长度为1.7～8.4％;而6年生“尾张”分别为对照的28.1～45.2％与6.1～11.5％。 调节膦抑制夏梢生长后,对秋梢、晚秋梢的发生数有所增加,但平均长度较对照短。经调节膦处理后的3年生“宫川”,产量增加,而品质无明显影响。
In order to restrain the growth of young mandarin summer shoots in juvenile and reduce the fall of June, a kind of efficient plant growth inhibitor-phosphoramidate (aminoethylformyl phosphate ammonium salt) The concentration is 250 ~ 1000ppm. The results showed that the incidence of summer shoots of “Miyagawa” of 3-year-old was 7.4 ~ 18.8% of the control, while that of 6-year-old “tail” was 15.8-28.1%. When the length of summer shoot was sprayed within 1.5 cm, the incidence of 3-year “Gongchuan” summer shoot was 5.3 ~ 7.4% and length was 1.7 ~ 8.4%, while the 6-year “tail” was 28.1 ~ 45.2 % And 6.1 ~ 11.5%. Phosphine inhibited the growth of summer shoots, the autumn shoots, the number of late autumn shoots increased, but the average length shorter than the control. The 3-year-old “Miyagawa” after the adjustment of the phosphine treatment increased the yield without any significant effect on the quality.
