摘要
在水资源缺乏的新疆地区,以"红提"葡萄、"秋田绿星"小白菜、"秋田南京红"萝卜为试材,研究了中水灌溉和污泥施肥对3个果蔬品种长势和品质的影响,以期为中水和污泥的合理利用提供理论依据。结果表明:用中水灌溉的葡萄长势好于清水灌溉的葡萄,但差异不显著;中水灌溉的葡萄中各生理指标含量均比清水灌溉的葡萄低,其中可溶性糖相差1.31个百分点,可溶性固形物相差2.42个百分点,可滴定酸相差0.01个百分点,蛋白质相差0.07个百分点,硝酸盐相差0.34mg/g,维生素C相差0.02mg/g。中水灌溉或施用污泥的小白菜长势均较好,而仅用清水灌溉的小白菜长势最差;仅用中水灌溉的萝卜长势较差,而施用污泥的萝卜长势较好。而"清水灌溉+污泥施肥"处理的小白菜和萝卜的蛋白质、可溶性糖、维生素C和硝酸盐含量均最高。
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.
