“906”系北京市农科院作物所花粉室从油菜花中直接提取含油菜素内酯等活性成分制成的植物生长调节剂。通过在棉花上试验,效果明显,具有促进生长、增加铃重、防止脱落、促进早熟、提高抗逆性和增产幅度大等作用。 试验采用0.01ppm和0.05ppm两个浓度,分初花期和盛花期两次喷施,以博林牌喷施宝为对照。其结果如下: 1、促进生长,减少脱落,促进早熟。喷施20天后调查,0.01ppm浓度处理的株高比对照增加6 “906” Department of Agriculture, Beijing Academy of Agricultural Crops pollen chamber from rape flowers directly extract containing brassinosteroids and other active ingredients made of plant growth regulators. Through the cotton test, the effect is obvious, with the promotion of growth, increase boll weight, prevent fall off, promote early maturity, increase resistance and increase the rate of large role. Experiments using 0.01ppm and 0.05ppm two concentrations, the initial flowering and flowering twice sprayed with Bolin licensing Penshibao control. The results are as follows: 1, promote growth, reduce loss, promote premature. After 20 days of spraying, the plant height at the 0.01 ppm concentration was increased by 6 compared with the control
