生长调节剂比久(B-9),过去成功地用于果树生产,已有很多应用报导,近年来应用范围扩及粮棉油作物。1975～1976年我们对玉米、大豆、甘薯、小麦等旱田作物开展应用试验,现将试验情况简介如下。一、比久在夏玉米上的应用试验玉米品种为“烟三6号”,每处理区面积3～4厘地,种植密度为每亩三千株,于玉米小花分化期和抽穗期以1000～5000 ppm整株喷雾,三次重复,以不处理为对照,收获时测产。
Growth regulator for a long time (B-9), the past successfully used for fruit tree production, there have been many applications reported in recent years, the scope of application of oil and cotton crops extended. From 1975 to 1976, we carried out application tests on dryland crops such as corn, soybean, sweet potato and wheat. The test conditions are as follows. First, a long time in the summer corn on the application of experimental varieties of maize “Yansan 6”, each processing area of 3 to 4 centimeters, planting density of 3,000 plants per acre, in floret differentiation and heading stage to 1000 ~ 5000 ppm whole plant spray, repeated three times, not treated as a control, measured at harvest.
