摘要 以紫油菜为材料,研究不同基质持水量(45%,60%,75%,90%)对其生长及生理特征的影响。结果表明:4个处理紫油菜的生长状况及生物量均优于常规灌溉,其中持水量90%的处理植株生长最佳。75%和90%的基质持水量处理下,紫油菜的含水量、可溶性糖含量和维生素C含量都显著高于其他处理,且硝态氮含量显著低于其他处理。叶绿素含量和可溶性蛋白含量以75%的处理最高,花青素含量以90%的处理最高。综合各指标分析可见,75%-90%的基质持水量下,紫油菜的综合品质表现最好。 Brassica campestris L. ssp. Chinensis cv. Ziyoucai( Ziyoucai) was used to study the effect of water holding capacity( WHC) on its growth and physiological characters. The results showed that different water holding capacities( 45%,60%,75%,90%) significantly affected growth and physiological features of Ziyoucai. Compared with the regular irrigation method,all 4 treatments significantly improved the growth of Ziyoucai and increased biomass production. Among 4 treatments,90% WHC exhibited the best effects. The content of water,soluble sugar and vitamin C under the treatment with 75% or 90% WHC was higher than other treatments,while the nitrate content was lower. The highest chlorophyll content and the highest soluble protein level were observed under the treatment with75% WHC,and the highest anthocyanins content was present under the treatment with 90% WHC. Taking together,the best comprehensive quality of Ziyoucai was achieved with 75%- 90% WHC.
