不同鱼腥草生物特性及高效高产栽培技术研究

对鱼腥草的生物学特性进行了调查观察,特别对鱼腥草的人工栽培技术等方面进行了探索研究。收集鱼腥草种质资源23个,进行种植保存;并建立30多亩生产示范基地。结果：不同种源鱼腥草主要经济性状存在显著差异,其中地上茎叶产量以11号处理最高干品产量达0.93kg/m^2,比最低的10号处理0.38kg/m^2高144.74%。地下根鲜产量以处理4最高达5.5kg/m^2,比最低的17号处理1.7kg/m^2高223.53%;通过对23个种源地上干品产量、地下根鲜品产量统计比较结果,可选用11号、17号、16号等作为售茎叶为主的药用栽培品种,3号、4号、13号等作为售鲜根为主的菜用栽培品种。在栽培地上套种吊瓜可增产增效。

Biological Properties and High Yielding Cultivation Technology of Houttuynia cordata

Houttuynia cordata biological characteristic was investigated and observed,Houttuynia cordata artificial cultivation technic was explored and studied.23 Houttuynia cordata seed resources were collected,and planted.More than 30 mu production demonstration base was built.The result:Houttuynia cordata economical characteristic had significant difference in different seed resources.Among them No.11 treatment had highest overground stem leaves yield,dry yield reached 0.93kg/m2,it was 144.74%higher than that of No.10 treatment which was 0.38 kg/m2.No.4 had the highest underground fresh root yield which reached 5.5 kg/m2,it was 223.53% higher than the lowest No.17 which was only 1.7 kg/m2.Through statistic comparison of overground dry yield,underground fresh root yield in 23 seed resources,No.11,No.17,No.16 could be selected as medical cultivation species which mainly sold leaves and stems,No.3,No.4,No.13 used as vegetable cultivation species which mainly sold fresh roots.Interplanting Trichosanthes kirilowii Maxim in the cultvation field could promote yield and efficiency.
