在20年生梨树上,采用湖北省鹤峰县科学试验站提供的ABT生根粉,于盛花期进行保花喷雾试验,共5个处理浓度(0、8、10、50、100ppm),在经过三次落果高峰后,进行座果率调查。经方差分析表明,各处理间的保花效果差异显著;经多重比较测验,以8ppm的保花效果最好。 通过试验我们认为:生
In 20-year-old pears, ABT rooting powder supplied by Hefeng County Scientific Experimental Station in Hubei Province was used to carry out flower spray test in full flowering stage. A total of 5 treatment concentrations (0, 8, 10, 50 and 100 ppm) After three fruit drop peak, carry out fruit rate survey. Analysis of variance showed that there was significant difference in the effect of flower protection between treatments. After multiple comparison tests, the flower protection effect of 8 ppm was the best. Through the experiment we think: students
