目前国内一些蔗区反映宿根甘蔗发株不齐、不全,缺株断垄多,有效茎数少,产量比新植庶低。生产上促进宿根甘蔗的发株,各地采用了不少措施,均有一定的效果,但仍有一定的局限性,需寻找更简单易行而有效的方法。从报道资料看,乙烯利和吲哚丁酸对促进分株和分蘖有良好的效果。本试验用赤霉素及吲哚丁酸处理宿根蔗头,研究其 At present, some sugar cane sugarcane areas in the country reflect substandard and incomplete sugarcane plants, which lack more effective stalks and produce fewer effective stalks than those with new plantings. There are some measures adopted in promoting the production of perennial sugarcane in the production, all of which have some effects. However, there are still some limitations. We must find a simpler and more effective method. From the information reported, ethephon and indole butyric acid have good effects on ratooning and tillering. In this experiment, we used gibberellin and indole butyric acid to deal with the sugarcane root in sugarcane and studied it
