植物激素在胶树的生产期用于增加胶乳产量方面,取得了很大的进展,但它几乎没有直接用于缩短非生产期。本文介绍植物激素促进胶树生长的初步试验结果:①筛选促进胶树生根的化合物;②生长素在橡胶扦插繁殖中的应用;③用植物激素刺激芽接桩、大树桩早生侧根和促进侧根发育;④确定最适浓度和有效施用方法;⑤测定大树桩在截根到移植之间使用生长调节剂的最适时间;⑥诱导分枝的有效配方等。 Plant hormones have made great strides in increasing the latex production during the gum tree production but are rarely used directly to shorten the non-productive period. This paper introduces the preliminary results of phytohormone to promote the growth of gum trees: ①Screening compounds that promote the rooting of gum trees; ②Application of auxin in rubber cutting propagation; ③Using phytohormone to stimulate buds, ④ determine the optimum concentration and effective application method; ⑤ determination of large stumps in the truncation to transplantation between the use of growth regulators, the most appropriate time; ⑥ induce effective branching formula.
