Abstract:: In Xinjiang region where are lack of water resources，with ‘Hongti’ grapes，‘Qiutianlvxing’ cabbages，‘Qiutiannanjinghong’ radishes as materials，the growth and quality of them under reclaimed water irrigation and sludge fertilizer were analyzed.The results showed that the grape irrigated with reclaimed water grew better than irrigated with clear water，but there wasn’t significant difference between them；the contents of measured indexes in grapes irrigated with reclaimed water were lower than those of irrigated with clear water.In detail，the difference between water soluble sugars were 1.31 points，between soluble solids 2.42 points，between titratable acids 0.01 points，between proteins 0.07 points，between nitrates 0.34 mg/g，between vitamin C 0.02 mg/g.Cabbages irrigated with reclaimed water or fertilized with sludge grew better，and the growth of those only irrigated with clear water were the worst.Radish only irrigated with reclaimed water grew worse，but grew better when fertilized with sludge.The protein，water soluble sugar，vitamin C and nitrates contents of cabbage and radish under reclaimed water irrigation+sludge fertilizer were the highest.
