Abstract：In order to study the effects of different irrigation amount on the physical and chemical proper-ties of continuous cropping soil under the rice -cucumber rotation mode,with greenhouse continuous cropping for 9 years,four treatments of different irrigation times (irrigating 1 time as T1 ,3 times as T2,5 times as T3 and non -irrigation as CK)were set by field block design during the period of cucumber harvest to rice plant-ing.The results showed that after irrigating for 2 months,compared with T1 and T2,T3 treatment could sig-nificantly reduce soil pH value and electrical conductivity.Compared with CK,the total nitrogen,available phosphorus and available potassium of T3 treatment reduced by 1 1 .40%,6.59% and 34.80% respectively. The soil available Cu and available Fe of T2 and T3 treatment both increased than before irrigation,while the available Zn was not significantly affected.
