选择云南勐海蔗区4个高感甘蔗宿根矮化病(RSD)的主栽品种粤糖93-159、粤糖00-236、ROC22、ROC20进行甘蔗温水脱毒种苗与常规种苗田间种植对比试验研究。结果表明,与常规种苗相比,温水脱毒种苗增产增糖效果显著。新植增产甘蔗558~2532 kg/667m2,增幅9.5%~54.73%;甘蔗糖分提高0.68~1.69个百分点。可见,种植温水脱毒种苗是防治甘蔗RSD最经济有效的措施之一,可大幅度提高甘蔗的产量和糖分,从而显著提高甘蔗生产的经济效益,增加蔗农收入,建议在勐海蔗区加快推广应用。
The main cultivars of high-yielding sugarcane root-dwarfing disease (RSD) in Yunnan Menghai sugarcane field were planted in field cultivation of sugarcane warm water detoxification seedlings and conventional seedlings in Guangdong sugar 93-159, Yueshun 00-236, ROC22 and ROC20 Comparative experimental study. The results showed that, compared with the conventional seedlings, warm water detoxification seedlings increase sugar yield significant effect. The new planting sugarcane 558 ~ 2532 kg / 667m2, an increase of 9.5% ~ 54.73%; cane sugar increased 0.68 ~ 1.69 percentage points. It can be seen that planting warm water virus-free seedlings is one of the most economical and effective measures for controlling RSD of sugar cane, which can greatly increase the yield and sugar content of sugar cane, thereby significantly increasing the economic benefits of sugar cane production and increasing the income of sugar cane farmers. Promote the application.
