摘要
为探索湿栽水芹（Oenanthe stolonifera D．C．）在春季生长适宜的最低土壤含水量，设置土壤相对含水量分别为60％～70％、70％-80％、80％和90％和90％～100％等4个梯度，来比较湿栽水芹新品系D07和G0601在春季3-5月的产量和品质差异。结果表明：D07在土壤相对含水量为80％－90％时产量最高、其粗纤维含量为6．48mg／g FW，G0601在土壤相对含水量90％以上时产量最高、粗纤维含量为6．64mg／g FW。粗纤维含量均为各处理最低，且可溶性蛋白和可溶性糖含量均较高。因此，综合产量与主要品质指标得出：土壤相对含水量80％是适宜D07生长的土壤含水量下限，土壤相对含水量90％是适宜G0601生长的土壤含水量下限。
In order to explore the lowest soil water content suitable for wet-cultivated water dropwort （Oenanthe stolonifera D.C.） to grow in spring, wet cultivation of 2 new water dropwort lines D07 and G0601 were studied between March and May in spring at 4 soil relative water contents, which were, 60%-70%, 70%-80%, 80%-90% and 90%-100%. The results showed that the D07 line＇s yield was the highest at soil relative water content of 80%-90% and its crude fiber content was 6.48 mg/g-FW, the G0601 line＇s yield was the highest at soil relative water content of 90%-100% and the products＇ crude fiber content was 6.64 mg/g-FW, when the both of the products＇ crude fiber contents were the lowest during the four different soil water contents, their soluble protein arid soluble sugar were in a higher degree. According to the yield and quality of the wet-cultivated water dropwort, we found that the soil relative water content of 80% was the lowest limit suitable for growth of the D07, and the soil relative water content of 90% was the lowest limit suitable for growth of the G0601.
