摘要
在甘蔗的分蘖初期用乙烯利、富镧稀土及其添加营养元素的复合制剂Ｈ１、Ｈ２进行叶面喷施。结果表明，各处理能明显提高甘蔗叶片的光合色素及水溶性蛋白质含量，增强叶片的苹果酸酶、酸性转化酶及多酚氧化酶等酶活性；并改善了甘蔗的产量性状，各处理的甘蔗有效茎数、茎长、茎径、单茎重及产量均高于对照。增产效应为Ｈ１＞Ｈ２＞乙烯利＞富镧稀土。
Sugarcane was sprayed with ethephon,lanthanum-rich rare earth,H_1,H_2(the mixture of ethephon and lanthanum-rich rare earth with some nutrient elements).The results showed that each treatment cane increased the contents of photosynthetic pigment and water soluble protein and the activities of malic enzyme,acid invertase and polyphenol oxidase in leaves as compared with the control,and the millable stalks,stalk length,stalk diameter,weight per stalk,and cane yield were higher than those of the control.The effects of yield promotion were:H_1>H_2>ethephon>lanthanum-rich rare earth.
