摘要
以3年大田定位试验为基础,研究山东东平3种典型质地土壤高产小麦生长发育及产量的变化。结果表明,中壤土的有机质、有效磷和碱解氮均高于轻壤土和重壤土;中壤土小麦冬前和返青期的分蘖和次生根数较高,成穗率也较高,籽粒产量最高。
Based on field location experiments for 3 years,the changes of growth,development and yield of high-yielding wheat were studied on 3 types of typical texture soils in Dongping,Shandong Province. The results showed that the contents of organic matter,available phosphorus and alkaline hydrolysis nitrogen in medium loam soil were all higher than those in light and heavy loam soil. Wheat in medium loam soil had more tiller and secondary root number before winter and at returning green stage,and had higher spike rate and the highest grain yield.
