新型植物生长调节剂BN是河南省农业科学院小麦研究所与上海植物生理研究所、上海化学所合作,利用他们合成的活性最强的甾醇物质与其它植物生长调节物质、营养物质复配成的一类新型复合调节剂。经试验,BN的活性比甾醇内脂强、成本低,结构稳定。其对小麦、玉米、大豆、烟草等作物均有较好的增产作用。尤其在小麦生长后期应用,其增粒、增产作用十分显著,是提高小麦对后期灾害气候抵抗能力,增加产量的一项有效措施。为便于各地进一步推广应用和试验示范,现将其在小麦上的部分应用试验报告刊登于后。
New plant growth regulator BN is the Institute of Wheat Research Institute of Henan Academy of Agricultural Sciences and the Shanghai Institute of Plant Physiology, Shanghai Institute of Chemistry, the use of their synthesis of the most active sterol substances and other plant growth regulating substances, nutrients compounded into Class of new compound regulator. After testing, the activity of BN is stronger than that of sterol, the cost is low, and the structure is stable. Its wheat, corn, soybeans, tobacco and other crops have a better yield. Especially in the late stage of wheat growth, the grain-raising and yield-increasing effects are very significant. It is an effective measure to increase the resistance of wheat to climate disasters in the later period and increase the yield. In order to facilitate the further promotion of applications and experimental demonstration all over the country, its application test report on wheat is now published later.
