A growth regulator specially for Jatropha curcas L. is made by the following method: dissolving cytokinins in sodium hydroxide solution, then diluting with distilled water to mother solution with cytokinins concentration of 0.02mg/mL-100mg/mL, uniformly mixing 2-9999 parts mother solution, 1-10 parts surfactant and 0-9997 parts distilled water to obtain said growth regulator. In 10 days before or after appearance of Jatropha curcas L. flower buds, uniformly spraying said growth regulator onto whole plant of Jatropha curcas L. until droplet drips down. After spraying 1-3 times during each Jatropha curcas L. blossoming period, total flowers, female proportion, fruits and seed yield are 3.6, 4.3, 4.5 and 3.9 times higher than untreated respectively. Oil content of the seed is increased to 34.76% from 31.67% and increased by about 9.8%. The present growth regulator operates simply and has lower cost.

一种麻疯树专用生长调节剂,按以下方法制备:将细胞分裂素溶于氢氧化钠溶液,用蒸馏水稀释成细胞分裂素浓度为0.02mg/mL-100mg/mL的母液,按2-9999份混合均匀 母液、表面活性剂1-10份、蒸馏水0-9997份,即得所述生长调节剂。 在麻疯树花蕾出现前后10天,将所述生长调节剂均匀喷洒在麻疯树全株上,直至液滴滴落。 麻疯树每个花期喷药1-3次后,总花量、雌花比例、果实产量和种子产量分别比未处理提高3.6、4.3、4.5和3.9倍。 种子含油量由31.67%提高到34.76%,提高了约9.8%。 本生长调节剂操作简单,成本较低。
