稀土能促进甘蔗生长,提高蔗茎产量;能提高甘蔗蔗糖分含量,降低还原糖含量,改善甘蔗品质。在土质肥沃的水田蔗区,稀土主要是通过提高分蘖成茎率,增加单位面积有效茎数和促进蔗茎的增粗而提高蔗茎产量的;在旱地蔗区,稀土主要是通过促进蔗茎的伸长和增加单位面积有效茎数而提高甘蔗产量的。
Rare earth can promote the growth of sugarcane, improve cane yield; can improve the sugar content of sugarcane, reducing the content of reducing sugar and improve the quality of sugarcane. In the fertile paddy fields, rare earths mainly increase the yield of cane stems by increasing the tiller tiller percentage, increasing the effective stem number per unit area and promoting the cane stem thickening. In the dry land cane area, Elongation and increase the effective number of stems per unit area and improve sugar cane production.
