旱地甘蔗温水脱毒健康种苗对比试验

摘要

ROC22, ROC16, Yuetang93-159, Guitang11, Guitang17, Guitang21, Yunzhe99-91, Yunzhe03-258, Dezhe03-83 were selected to take part in a comparison test to compare their field performances of hot-water-treated seeds with regular seeds. The result indicated that all 9 varieties treated with hot water showed yield increasing effect. The yields of new-plant cane increased by 10.29~23.85 t/hm2, 11.6%~35.1%more than that of growing regular seeds. The yields of ratoon cane increased by 16.83~32.13 t/hm2 t/hm2, 16.9%~51.2%more than that of growing regular seeds. Therefore, hot water treatment is an effective way to control RSD and should be promoted in sugarcane production, and it can significantly increase production benefit and cane grower’s income.%在旱坡地选用ROC22、ROC16、粤糖93-159、桂糖11号、桂糖17号、桂糖21号、云蔗99-91、云蔗03-258、德蔗03-83等9个品种进行甘蔗温水脱毒健康种苗与常规种苗田间种植对比试验研究，结果表明：9个品种甘蔗温水脱毒健康种苗均具有显著的增产效果，新植增产甘蔗10.29～23.85 t/hm2，增幅11.6%～35.1%；宿根增产甘蔗16.83～32.13 t/hm2，增幅16.9%～51.2%。可见，种植温水脱毒健康种苗是防治甘蔗宿根矮化病(RSD)最经济有效的措施，在生产上应加快推广应用，可显著提高甘蔗生产的经济效益，增加蔗农收入。
