摘要
研究了耐渍性小麦农家品种和大面积推广的高产栽培品种在渍害条件下N、P、K、Cu、Zn的营养吸收特点。试验结果表明,耐渍性农家品种受渍后具有较强的营养吸收和运输能力,而大部分栽培品种营养元素的吸收均明显下降。渍害影响小麦N、P、K、Zn的吸收,对其在体内的运转影响不大。
In the present study,the characteristics of the absorption of N,P,K,Cu and Zn of the wet resistant wheat varieties and non-wet resistant ones were investigated.The nutrients were absorbed and translated well in the wheat of strong tolerance to wet but decreased in most normal wheat cultivars.The wet injury mainly affected the absorption of N,P,K and Zn in wheat but not the translation.The absorption and translation of Cu were inhibited by flooding.
