项目摘要
It is very important to use native grass for fodder crop or re-vegetation because of problems of invading species of commercial based seeds of pasture grass. Escaped pasture grass had been invaded to various ecosystems and they negatively changed bio-diversity. Then, many ecologists recommend to use the native grass for artificial grassland. But, there are some problems for using native grass such as difficulty of seed collection. Seed collection of Japanese native grass is very difficult because of small seed with pappus. We can not use common seed harvester for native grass. And, it is very difficult to adjust the all seed of native grass to artificial condition because there are many genetic variations in only one population. So, we tried to search adequate varieties for re-vegetation. And,we tried to exploit seed harvester for native grass.There are some varieties having large seed with no seed dormancy. It is thought that these varieties are very useful for re-vegetation. We exploited the seed harvester by miner change of handy engine duster. The efficiency of seed collection is very high of this seed harvester compare to hand collection. These results is very important for using native grass by seed propagation.
由于牧草商业种子的入侵问题,利用本地牧草作为饲料作物或恢复植被非常重要。逃逸的牧草已经侵入到各种生态系统中,对生物多样性产生了负面影响。因此,许多生态学家建议使用本地草作为人工草地。但利用乡土草也存在种子收集困难等问题。日本原生草种子小,且具冠毛,采集难度大。我们不能使用普通的种子收割机为本地草。而且,由于一个群体中存在着许多遗传变异,因此很难将所有的天然牧草种子调整到人工条件下。因此,我们试图寻找适当的品种进行重新植被。同时,我们还尝试开发了适合本地牧草的种子收获机,有些品种种子大,种子不休眠。人们认为这些品种对植被恢复非常有用。我们用轻便发动机喷粉机改装成种子收获机。与手工采种相比,该机采种效率高.这些结果对利用乡土牧草进行种子繁殖具有重要意义。
