自从发现植物生长素及生长素的人工合成以来,除去理论研究上有很多论著外,在实际应用上也有一些研究报导,尤其是近几年来,有些地区已经把生长素应用在较大面积的农、园艺生产实践上。此外,有一部分化学药剂对植物的生长也有刺激作用,其中值得提出的即保加利亚波波夫院士所介绍的溴化钾;可在大面积生产上获得增产效果。国内也有一些试用的,大部皆有相当效验。按植物生长素对于促进发根的效果已为肯定事实,过去在甘藷秧苗的应用上曾有部分报告资料,一般增产效果均在10％以上,按甘藷在农作物中系一高产作物,解放后农民
Since the founding of auxin and auxin artificial synthesis, in addition to many theoretical studies on the outside, the practical application of some studies have reported, especially in recent years, some areas have been applied to the application of auxin in a large area of farmers , Horticultural production in practice. In addition, some chemicals also stimulate the growth of plants. Among them, it is worth mentioning that potassium bromide introduced by Academician Popov in Bulgaria; can increase the yield of large-scale production. There are some domestic trials, most of them are quite effective. According to the auxin auxotrophic effect on hair root has been affirmed the fact that in the past in the application of sweet potato seedlings there have been some reports, the general increase in production are more than 10%, according to the sweet potato in a crop of high-yielding crops, peasants after liberation
