再生水灌溉对果菜类蔬菜产量及品质的影响

为推动再生水灌溉作物的适宜性分类，该文研究了再生水灌溉对果菜类蔬菜产量与品质的影响。结果表明，再生水处理与对照处理相比可显著增加果菜类蔬菜产量，其中，西红柿、黄瓜平均增产15.1%、23.6%。茄子、豆角增产60.7%、7.4%。再生水灌溉对果实含水率、粗蛋白、氨基酸含量、可溶性总糖、维生素C、粗灰分、硝酸盐、亚硝酸盐等品质或营养指标无显著影响，再生水灌溉处理硝酸盐、亚硝酸盐含量低于标准限值。研究为再生水适宜灌溉的作物筛选提供了技术依据。

Effect of reclaimed water irrigation on yield and quality of fruity vegetables

For promoting feasible classification of crops for reclaimed water irrigation, the effect of reclaimed water irrigation (RWI) on the yield and quality of fruity vegetables was conducted. The yield of fruity vegetables significantly increased under the condition of RWI. The tests results indicated that the average yield of tomato and cucumber under the condition of RWI increased by 15.1% and 23.6%, and the average yield of eggplant and kidney bean under the condition of RWI increased by 60.7% and 7.4% compared with control check. There were no significant differences of reclaimed water irrigation on water content, crude protein, amino acid content, soluble sugar, vitamin C, coarse ash, nitrate, nitrite and nutrition indexes of fruity vegetables. Both nitrate content and nitrite content under the condition of RWI were below the standard limit. The study can provide technical basis for selecting the crops which are suitable for reclaimed water irrigation.
