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.
