摘要
研究了不同施氮处理对旱地小麦叶绿素和糖含量的影响,结果表明,旱地小麦一次施氮肥能增大叶面积,增加功能叶片叶绿素、总糖和可溶性糖含量,呈正比关系。在旱地土壤肥力低的条件下,一次施适量氮肥,可促进小麦增产。
Effects of N fertilizer on the amount of chlorophyll and carbohydrate in dryland wheat leaf were studied. The result showed that the application of N fertilizer to dryland wheat could enlarge wheat leaf area, thus increasing the amount of chlorophyll, carbohydrate and soluble sugar. The level of such increases was directly proportional to the level of nitrogen. Under lower fertility conditions, the fertilization with the appropriate amount of nitrogen in this area could increase wheat yield and enhance wheat drought resistance.
