In this paper

adopted interval coverage combined with soil conditioner

influence of this method on soil water movement and distribution were investigated by using indoor artificial rainfall and soil column ex- periments.The results showed that :(1)Soil water storage in infiltration zone could be increased

when area ration was 1 :1

soil water storage could reach 1.83 times of total rainfall.Combined with application of soil conditioner

under I=60mm/h and the area ratio of 1 :1

rainfall infiltration rate can be achieved 2.60 times of that of the treatment without soil conditioner.Wetting front reached deeper

and water distribution uniformity has been upgraded.(2)With application of soil conditioner

evaporation was controlled

soil wa- ter-holding and absorption capacity were improved

but the two are closely related with the amount of PAM. Moreover

while the study confirmed the results of the practicality of this method

but the appropriate a- mount of soil amendments

the appropriate interval overlay area ratio

the actual water control effects and the impact on the crop still need further be studied.
