盈江县甘蔗宿根矮化病的调查与思考

通过对盈江县甘蔗宿根矮化病（RSD）的调查、检测,结果显示,RSD占80%;对2012年温水脱毒健康种苗进行田间测产,与未脱毒甘蔗的产量比较增34.995 t/hm2,增产率36%,说明RSD在盈江县蔗区普遍发生,但通过培育和推广应用甘蔗健康种苗,不仅可有效控治甘蔗宿根矮化病的蔓延,而且增产效果明显。本文结合盈江县甘蔗发展实际情况,针对当前存在的问题,提出下一步防治甘蔗宿根矮化病的防治对策。

Investigation and Suggestion for Sugarcane Ratoon Stunting Disease in Yingjiang County

The investigation and detection of Ratoon Stunting Disease （RSD） of ratoon sugarcane in Yingjiang County showed that 80% of the total have RSD. The cane yield cultivating virus-free seedling treated with warm water was 34.995 t/hm2 （an increase rate of 36%） higher than that using non virus-free seedling. The result indicated that RSD is widespread in sugarcane planting areas of Yingjiang, but can be controlled by the promotion of growing healthy seedling, increasing cane yield significantly. The suggestion on the countermeasures of RSD control is offered combined with the actual development of sugarcane industry in Yingjiang according to the current problems.
