摘要:
对沙壤土、壤土和粘壤土分别进行了单滴头、单管道田间灌水试验。结果表明,沿滴灌管长度方向土训湿润较均匀,作物主要吸水根系土层内土壤湿润均匀,作物行间有6~20 cm未湿润区域;无地膜覆盖地面滴灌(裸地滴灌)与膜下滴灌相比较,节水约3.3%。

The under membrane drip irrigation technical study
Abstract:
Based on the field irrigation of single drip-filter with the sand soil,the loam and the clay loam,we had done the single-pipe irrigation,obtained the well-distributed soil wetness along the direction of the drip-pipe and the root soil area,the soil between the crop liners about 6-20 cm in width is not well irrigated compared with the nakedness soil,the under membrane drip irrigation can save the water 39.3%.
Key words:  the under membrane drip irrigation  water saving  the bare drip irrigation  drip irrigation technical
