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 explore the application effect of new sugarcane varieties of healthy seedlings, six new varieties of sugarcane were compared for two years with healthy seedlings. The results showed that: (1) The healthy seedlings could significantly increase the yield and sugar content of sugarcane, which could extend from new sugarcane to sugarcane and vary with different varieties. Healthy seedling sugar cane yield increased 16.4%, 15.9% increase in sugar content. (2) Healthy seedlings had no significant effect on cane sugar content. (3) The effect of healthy seedlings on the yield traits of sugarcane is multifaceted, which can promote the germination of sugarcane and increase the tillering, plant height, stem diameter and number of effective stalks. The results of this experiment on healthy seedlings in sugarcane production has a certain guiding role.
