摘　　要：通过负压计、中子仪、地下水埋深监测研究,得出生育期田间水分变化规律及土壤水分利用效率;5次灌水均有深层渗漏,土壤都能达到饱;在生育期间,土壤水和地下水相互转换关系活跃。With negative pressure gauge, neutron instrument and monitor research for depth of embedment of groundwater, we can obtain the changeable regulation of the soil moisture change in field and moisture use efficiency in field at childbearing period; in five irrigation water,every time all has deep seepage,and the soil all can reach to saturation; in childbearing period, the mutual change relation of irrigation water and groundwater is active.

关 键 词：生育期 田间水分变化 水分利用效率 深层渗漏
