摘　　要：为探讨甘蔗新品种健康种苗的应用效应,对6个甘蔗新品种进行了为期两年的健康种苗对比试验。结果表明:(1)健康种苗可显著增加甘蔗产量和含糖量,这种效应可从新植蔗延续至宿根蔗且因品种而异。健康种苗甘蔗产量增产16.4%,含糖量增产15.9%。(2)健康种苗对甘蔗蔗糖分无显著作用。(3)健康种苗对甘蔗产量性状作用是多方面的,可促进甘蔗发芽出苗,增加分蘖、株高、茎径和有效茎数。该试验结果对健康种苗在甘蔗生产上的应用具有一定的指导作用。In order to investigate the healthy seedcane effect of applying new sugarcane varieties,on six sugarcane varieties were conducted the in 2-year comparison test of healthy seedcane.The results showed that：⑴ can be significantly increased the production and sugar content of sugarcane in the treatment of healthy seedcane,the continued effect from planting cane to ratoon cane was varied with varieties.The yield of healthy seedcane was increased by 16.4%,and sugar content was increased by 15.9%.⑵ There were not significant influences of healthy seedcane on cane sucrose.⑶Healthy seedcane effect was variously on sugarcane yield,itcan promote the germination of sugarcane seedcane and increase tillering,height,diameter and the number of productive tiller.The results offer a directive function to the healthy seedcane on application of sugarcane production.Abstract：
