灌溉对玉米生育性状及体内氮素变化的影响

Irrigation Effect on the Growth Characteristics and Nitrogen Variation of Maize

分析了灌与不灌对玉米的株高、叶面积、干物重等生育性状的影响和不同生育期氮素养分的动态变化。研究表明 :灌溉可增加玉米的株高、叶面积、干物重 ;促进玉米对氮素养分的吸收 ;各生育期玉米的氮素吸收量随着施肥量增加而增加 ;

In this paper maize crop growth characteristics such as the stem height, the leaf size and the dry matter weight of maize under different irrigation conditions (irrigation and non-irrigation) was analyzed, meanwhile, the dynamic variation of nitrogen during different growth periods was investigated
