膜下滴灌技术研究

The under membrane drip irrigation technical study

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壤湿润较均匀 ,作物主要吸水根系土层内土壤湿润均匀 ,作物行间有 6～ 2 0 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 39.3%。

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%.
