Abstract :本研究では,植物の生理,生長状況,生物量,土壌への改善効果から,無小葉花棒と多小葉花棒との差異を検討した。得られた結果を要約すると,つぎのようになる。(1) 両生態型花棒の葉形態特徴,葉の解剖構造,葉の水分生理および根系の分布状況の分析によって,多小葉花棒に比して無小葉花棒はさらに乾燥環境に耐えられることが明らかになった。(2) 多小葉花棒の種子の品質は無小葉花棒より優り,種子の実用価値が無小葉花棒種子の2.24倍である。多小葉花棒の生枝・葉の粗蛋白質,粗脂肪含量および無窒素浸出物が無小葉花棒に比して多いので,飼料として高い価値を有する。(3) 流動砂地と比べて,無小葉花棒地および多小葉花棒地の土壌の理化学性は改善された。土壌の物理性の改善において,無小葉花棒は多小葉花棒に比して効果である。
In the previous paper, we have divided the H. scoparium into two ecotypes by use of the cluster analysis method, and named them as non-leaflet and poly-leaflet H. scoparium respectively. In order to serve the afforestation in desert area, we measured and analyzed some bioecological and physiological characteristics of these two ecotypes. As the results, it was revealed that, 1), the non-leaflet ecotype of H. scoparium is more obviously characterized with drought-against features in the aspects of leaf shape, leaf anatomical structure, physiological characteristics in water using, and root distribution; 2), the seed quality and of the non-leaflet ecotype is better than that of polyleaflet ecotype, but the fresh branch and leaves of poly-leaflet ecotype contains more gross protein, gross fat, non-nitrogen extractives than non-leaflet ecotype, and is more suitable to use as a kind of forage; 3), the soil physical property of non-leaflet ecotype is better than poly-leaflet ecotype.
