奥普尔、稀土作基肥施用，对甘蔗的生长均具促进作用，奥普尔能促使甘蔗早出苗，多分蘖。稀土作基肥，能有效促进蔗茎生长，提高成茎率。作叶面肥施用，奥普尔、惠满丰和稀土都能提高甘蔗糖分，也有一定的增产效应。最终增糖效应以奥普尔基施＋叶面喷施为最明显，其后依次是奥普尔叶面喷施、稀土基施＋奥普尔叶面喷施，惠满丰叶面喷施。 Opal, rare earth for basal fertilizer application, on the growth of sugarcane are to promote the role of Opal can promote sugarcane early emergence, tillering more. Rare earth as a base fertilizer, can effectively promote the cane growth, increase the rate into stems. For foliar application, Opal, Hui Man Fung and rare earth can improve sugar cane, but also a certain yield-increasing effect. In the end, the effect of sugar increase was most obvious after applying Opheliji + foliar spray followed by the application of Opal foliar spray, the application of rare earth basal plus Opal foliar spray, and the benefit of foliar spray.
