整形素是一类高效、低毒、内吸性的多用途的新型植物生长调节剂。目前国内尚无商品。1977年以来,北京农业大学研制合成了多种整形素类化合物,并均加工成相应剂型,进行药效试验以探索其在大田作物、果树、蔬菜、橡胶、林业等生产上的应用前景。整形素在桃树上的应用研究,是北京农业大学与河北农大唐山分校共同合作进行的,试验分以下几个阶段:1979年～1980年为试验的准备阶段。1979年在苹果幼树上用整形素 B 和整形素 C、调节膦、矮壮素 A_1、B_9做药效对比观察,发现整形素在控制果树新梢生长上具有独特的作用,其效果显著高于其它药物。按相同浓度计,整形素 C 的活性大干整形素 B。1980年又用相同的几种药剂扩大到葡萄和桃等几种果树上进行试验,均表现出整形素的优越性。特别是在桃
Orthodontic is a class of highly effective, low toxicity, systemic multi-purpose new plant growth regulator. At present there is no product. Since 1977, Beijing A & M University has developed and synthesized a variety of orthophosphoric compounds and processed them into corresponding dosage forms for efficacy testing to explore their application prospect in field crops, fruit trees, vegetables, rubber and forestry. Application of plastic in peach tree research, Beijing Agricultural University and Hebei Agricultural University, Tangshan branch co-operation, the test points the following stages: 1979 to 1980 for the preparation phase of the trial. In 1979, young apple trees with plasticine B and C, phosphine, CCC A_1, B_9 do comparative observation of the efficacy and found that the plastic mold in the control of fruit tree shoot growth has a unique effect, the effect was significantly higher In other drugs. According to the same concentration, the activity of CTC is bigger. In 1980 with the same number of agents expanded to grape and peach and other fruit trees on the test, showed the superiority of the orthopedic. Especially in the peach
