美国农业研究局的植物生理学家和土壤学家采用判读小麦植株的分蘖的方法,能确定小麦植株是否处于不利环境,以及受害的严重程度。有了这方面的知识,种植者可调整管理措施,以纠正目前的或将要发生的不利情况。小麦分蘖决定有效穗数。植株自身形成的分蘖比其需要的多得多。一般有三分之一至一半的分蘖为无效分蘖。环 Plant Physiologists and soil scientists at the Bureau of Agricultural Research use a method of interpreting the tillering of wheat plants to determine whether the wheat plant is in an adverse environment and the severity of the damage. With this knowledge, growers can adjust management measures to correct current or potential adverse conditions. The tillering of wheat determines the effective panicle number. Plants themselves produce much more tillers than they need. Generally one third to one half of the tillers are ineffective tillers. ring
