| 摘 要： | 以黑龙江省龙江县玉米主栽品种葫科336为试材，采用自然条件下对比观测田间试验，研究分析不同土壤湿度对玉米生长的影响。结果表明：2011年龙江县试验田不同表层(0-30 cm)土壤湿度均呈下降趋势。试验田不同表层土壤湿度对玉米生长的影响存在差异，不同土壤湿度对玉米绿叶叶面积、植株干物重影响明显，在一定土壤湿度范围内，土壤相对湿度每升高1 %，叶面积增加28.338 cm2，土壤无旱对叶面积增加具有正效应，对玉米果实重量的增加也呈有利趋势。

| Abstract: | The main maize variety （Huke 336） in Heilongjiang province was treated with the contrast observation under natural conditions in the maize field,and the effect of different soil moisture on maize growth was analyzed.The results show that soil moisture in the different surface layers （0-30 cm） is in a decreasing tendency in 2011 in Longjiang maize field.The effect of soil moisture in different soil layer on maize growth is different.It has a significant effect on green leaves area and dry weight.Within a certain soil moisture range,the leaf area will increase 28.34 cm2 if soil moisture increases 1％.Suitable surface soil moisture is favorable to increase green leaf area and dry matter of maize. |
