我们从1982年开始,应用生长延缓剂B_9、矮壮素、健壮素、调节膦等,开展了抑制柑桔夏梢发生、减少落果增加产量的试验和应用,经连续四年工作,确认以调节膦的效果最好。一、材料和方法试验和应用均在本市前卫农场进行。 1982年试验:6月14日夏梢萌发时,喷2000ppmB_9、3000ppm健壮素、2000ppm矮壮素、1000ppm调节膦,品种“尾张”,1979年定植,重复9次,随机排列。 1983年试验:6月15日夏梢萌发时,喷250、500ppm调节膦,250ppm调节膦+3000ppm健壮素,500ppm调节膦+3000ppm健壮素,品种“尾张”,1979
We started from 1982, the application of growth retardants B_9, CCC, Jian Su, regulating phosphine, carried out to inhibit the occurrence of citrus summer shoots and reduce fruit drop to increase the yield of the test and application, after four years of continuous work to confirm the regulation Phosphine works best. First, materials and methods Tests and applications are carried out in the city avant-garde farms. 1982 test: June 14 summer shoot germination, spraying 2000ppmB_9, 3000ppm Jian Su Su, 2000ppm CCC, 1000ppm regulation of phosphine, varieties of “tail”, planted in 1979, repeated 9 times randomly arranged. 1983 test: June 15 when the summer shoot germination, spraying 250,500ppm adjusting phosphine, 250ppm adjusting phosphine + 3000ppm healthy prime, 500ppm regulating phosphine + 3000ppm healthy prime varieties “tail”, 1979
