甘蔗收砍后,留在地里的宿根蔗头很容易感染病菌,从而引起风梨病、赤腐病等,造成宿根蔗头腐烂,出苗少,苗弱,影响来年产量。这是长期以来宿根蔗生产上一个最大的问题.试验采用800倍的50%可湿性甲基托布津,500倍的强氯精和0.09%的倍生30A(美国进口),以喷清水为对照,于前造蔗收获后3—4天喷施蔗桩调查结果表明,喷药处理的蔗茎产量均比对照增产,亩增产0.15～0.5吨,增产幅度为2.9～9.8%。各喷药处理间相比,产
After the sugarcane is cut off, the dormant sugarcane head in the ground is easy to infect with the bacteria, causing the pear-pear disease and the red rot disease, causing the rot of the sugarcane root in the root, with less emergence and weak seedling, affecting the coming year’s output. This is one of the biggest problems in the production of ratoon cane for a long time.The experiment used 800 times of 50% wet thiophanate-methyl, 500 times of strong chlorine and 0.09% of secondary 30A (US imports) The results of spraying sugarcane 3-4 days after the harvesting of the former sugarcane showed that the yield of cane stems of the spraying treatment increased by 0.15-0.5 tons and the yield increase was 2.9-9.8% compared with the control. The spraying process compared to production
