摘要
对玉米田土壤水分的研究结果表明 ,玉米田土壤水分低于裸地土壤 ,在玉米生育前期二者差异小 ,中后期差异加大 ;玉米田土壤水分随降水时间和强度波动 ,但在时间上有一滞后期 ,土层自上而下可分为 3个变化层 ;
The results of the study on the soil moisture in the cornfield showed that the cornfield had a lower moisture content than cellar harvested field.the difference between them was small during the former stage of corn growth,but it incereased in the middle and later stage;the soil moisture content in the cornfield varied with the frequency and density of rainfall,but there was a lagging period in time,the soil moisture dynamics in vertical direction could be diveded into three types,planting density was one of the most important factors afectiong crops' water consumption.
