渍害条件下小麦营养吸收特点

研究了耐清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、捐收，对其在体内的运转影响不大，而对小麦Ｃｕ的吸收和转移均有抑制作用。

Characteristics of the Nutrition Absorption of Wheat under Flooding Soil

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.
