摘　　要：无论人工喷施或飞机喷施,均能促进甘蔗生长,增加单茎重,提高蔗茎产量和蔗茎蔗糖分。人工喷施方法,采用2000倍稀释液效果较好;飞机喷施采用250倍稀释液对蔗茎产量的增加效果好,而200倍稀释液则对蔗茎蔗糖分的提高有较好的效果。Results indicated that the yield and sucrose content of cane sprayed with the Nitropotassium Aqueous Ageat (2% CNKAA ) in cane seedling stage could be increased. It would be the best result that cane seedlings were by hand using concentration diluted 2000 times of the CNKAA. Cane yield and sucrose content of cane would be better, improved to spray with the concentration diluted 250 times and ICO times of the CNKAA by airplane, respectively.
