普那菊苣引种栽培试验

Experiment on the Introduction and Cultivation of Puna Chicory

研究了普那菊苣在引种地的株高生长状况、茎叶比、营养成分及病虫害防治等生物学特性。结果表明:在保证水肥供应及普通田间管理情况下,普那菊苣在引种地能正常完成生物周期且生长较快,刈割后再生能力强,产草量高,营养成分含量高,病虫害少,可作为该区域优良的叶菜类饲草进行开发利用。

The biological characteristics of puna chicory including the plant height, the stem-leaf ratio, nutritional components,the control of diseases and pests in the introduction area were studied. The results showed that puna chicory could complete the biological cycle normally and grow faster when the supplication of water and fertilizers and the normal field management were ensured. It had some characters such as strong regeneration ability after cutting, high grass production and high nutritional component content and few diseases and pests. So it could be taken as a kind of good leafy-vegetable forage grass to develop and utilize in this area.
