摘要
在温室条件下采用盆栽试验方法种植小白菜,研究再生水灌溉对不同类型土壤小白菜水分利用效率和品质的影响。结果表明,再生水灌溉可显著增加红壤、潮土、塿土小白菜生物量,分别为9.1%、16.1%、9.9%;黑土小白菜生物量增加不显著;再生水灌溉可显著增加了红壤和塿土小白菜水分利用效率,分别增加6.3%和9.6%,而潮土和黑土则没有达到显著水平;再生水灌溉对4类土壤小白菜Vc、可溶性糖、蛋白质含量影响不大。
Green house pot culture was adopted to study the effects of reclaimed wastewater irrigation on water use efficiency and P uptake of green vegetables in different kinds of soils. The results showed：with the increase of reclaimed municipal wastewater,in comparison with the control,the dry weight of green vegetables in red soil,fluvo-aquic soil,loess soil,increased by 9. 1%,16. 1%,and 9. 9%,respectively,but there was no change for Black soil. Reclaimed wastewater irrigation increased the green vegetables water use efficiency in red soil and loess soil,by 6. 3%,9. 6%,respectively,but there was no change for fluvo-aquic soil and black soil. Significant differences were not found in cabbage Vc,soluble protein and soluble sugar concentration under reclaimed wastewater treatments.
