锰、锌、铜都是植物必需的微量营养元素,在小麦的生长发育过程中有很重要的作用。许多地区的试验表明:锰、锌、铜肥单施能增加冬小麦株高和分蘖数,使成熟提前,产量增加,品质改善,干物质积累增加并促进其向籽粒中分配;三种肥料两两配施效果更加显著,如果Mn-Zn、Mn-Cu配合比例失调则会产生拮抗作用。 Manganese, zinc and copper are essential micronutrients for plants and play an important role in the growth and development of wheat. Tests in many areas showed that the single application of manganese, zinc and copper fertilizer could increase the plant height and tiller number of winter wheat, advance the maturity, increase the yield, improve the quality, increase the dry matter accumulation and promote the distribution to the grain; The compounding effect is more remarkable. If Mn-Zn and Mn-Cu are mismatched, the antagonism will be produced.
