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, where water resources are scarce, the effects of middle-water irrigation and sludge fertilization on the growth of 3 A fruit and vegetable varieties growing and quality impact, in order to provide a theoretical basis for the rational use of water and sludge. The results showed that the grapes irrigated with medium water grew better than those irrigated with fresh water, but the difference was insignificant. The content of physiological indexes of grapes irrigated with medium water was lower than that of fresh irrigated grapes, the difference of soluble sugar was 1.31% The difference of 2.42 percentage points, titratable acid difference of 0.01 percentage points, the protein difference of 0.07 percentage points, nitrate difference of 0.34mg / g, vitamin C difference 0.02mg / g. The growth of Chinese cabbage under water irrigation or sludge application was better, while the cabbage irrigated with pure water was the worst. The radish irrigated only by the medium water was in poor condition, while the radish with sludge was better. However, the contents of soluble sugar, vitamin C and nitrate in cabbage and radish treated with “water irrigation + sludge fertilization” were the highest.
