摘要
胡枝子属(Lespedeza)的部分种属于自花授粉植物,部分属于异花授粉植物。该属植物种子硬实性比较高,在播种时需要处理,破除其硬实性,才能保证其播种时有较好的出苗率。抗逆性研究比较少,主要集中在种子萌发期及幼苗的抗逆性,对后期生长研究比较少;种研究的也比较少,主要集中在少数几个种上。胡枝子属植物具有较大的药用价值,在西部干旱山区和水土流失地区栽植,既能防止水土流失,也能为当地群众提供一定的经济收入。我国进行胡枝子属植物研究的单位比较少,未能系统的对其进行深入研究,所涉及的种比较少,研究的技术手段比较落后。因此,需要扩大研究单位以及加强科研单位之间的合作,争取国家更多的经费投入,对胡枝子属植物进行全面而深入的研究,使其在生态环境建设、退化草地改造以及促进农村经济发展等方面发挥更大的作用。
Some species of Lespedeza genus belong to self-fertilizing,and the others are cross-pollination.The Lespedeza seeds are very hard.It is need to some treatments to break the hard seeds when seedling,so there are good seedling emergence rate.Most researches about Lespedeza focus on resistance of seed germination and seedlings.It is very few to study the resistance in later growth period.There are fewer study on species,and just focus on a few species.Most Lespedeza plants have important medical value.They can prevent soil erosion and increase income of the local peoples when planting in western arid mountain and soil erosion areas.Based on few research institutions in Lespedeza plants,there is no systemic research and there are fewer studied species,even the technology is relatively backward in China.So it is very important to extend and enhance the cooperation of institutions,strive for more funds input.And further make comprehensive study on Lespedeza plants in order to make great effect on constructing ecological environment,improving degraded grasslands and developing urban economy.
