1984—1985年,我们在武胜县沿口乡应用防落素(对氯苯氧乙酸)对柑桔幼树进行了保果试验。 供试防落素粉剂为四川化工厂生产(编号Ⅰ)和永川化工厂生产(编号Ⅱ)两种。1984年在生长基本一致的6年生锦橙上,用防落素Ⅰ号,设30、40ppm两处理,每处理3株,以不喷药为对照,顺序排列。于5月18日、6月11日各喷药一次,至10月8日调查着果数,计算着果率。为探明不同产地防落素对六月落果的效应,1985年在4年生血橙上,用防落
In 1984-1985, we carried out the fruit-preserving test on the seedlings of young citrus trees with the use of anti-down factors (p-chlorphenoxyacetic acid) in Yankou Township, Wusheng County. Test for the falling-off powder for the production of chemical plant in Sichuan (No. Ⅰ) and Yongchuan Chemical Plant production (No. Ⅱ) two. In 1984, basically the same growth of 6-year-old brocade orange, with anti-PC 1, set 30,40ppm two treatment, each treatment of 3, with no spray as a control, arranged in order. On May 18, June 11, each spraying once, until October 8 to investigate the number of fruit, calculate fruit rate. In order to find out the effect of the anti-pigs from different origins on the fall of June, on the 4-year raw blood orange in 1985,
