应用对氯苯氧乙酸或四碘苯氧乙酸提高苹果座果率,国内外均有大量材料报道。而用四溴苯氧乙酸则报道不多。1985年我们在沂源县西鱼台和九会果园试用四溴苯氧乙酸对红香蕉及小国光两个品种进行初步试验,获得良好效果。两个品种的座果率明显提高,单株增产显著。
Application of p-chlorophenoxyacetic acid or tetraiodo-phenoxyacetic acid to improve the rate of apple fruit, both at home and abroad have a lot of material reported. However, tetrabromophenoxyacetic acid is not reported. In 1985, we tried the trial of tetrabromophenoxyacetic acid at Xiyutai and Jiuhui Orchards in Yiyuan County to test the red banana and Xiaoguangguang varieties for good results. The fruit set rate of two cultivars increased obviously, and the yield per plant was significant.
