| 摘 要： | 通过田间试验,研究再生水不同灌溉处理对黄瓜、西红柿植株各部位养分元素的分布特征及果实品质的影响.结果表明:再生水灌溉对西红柿的生长发育有促进作用,对黄瓜的生长发育有一定的抑制作用.再生水灌溉后,氮具有向植株地上部分运输的特征;钾易于在黄瓜叶片中富集,不易于在西红柿根部富集;钠主要富集在根系中,叶片中的浓度较低,不会对作物造成伤害;对各部位Ca2+、Mg2+、Cl-的分配没有显著影响.再生水灌溉对黄瓜、西红柿品质无显著影响,果实中硝态氮浓度分别增加了5.3%和32.9%,但均低于国家标准限值. |

| Abstract: | A field experiment was conducted to investigate the effects of irrigation with treated wastewater on the nutrient distribution in cucumber and tomato plants and their fruit quality.Irrigation with treated wastewater promoted tomato growth significantly,but had definite inhibition effect on cucumber growth.After the irrigation with treated wastewater,the nitrogen in plants had the characteristics of upward translocation,potassium was easily to be accumulated in cucumber leaf but not accumulated in tomato roo... |
| Keywords: | irrigation with treated wastewater cucumber tomato nutrient element quality. |
