荒漠草原“科尔沁型”华北驼绒藜旱作技术研究

“科尔沁型”华北驼绒藜是优良的旱生牧草,但其果实带毛、粘连,不适宜机械播种,而且种子发芽要求较高的温度、湿度,在荒漠草原地区直接播种,建立旱作人工草地难度很大。采用育苗,机械化植苗技术,在撂荒、退耕地建立旱作人工草地,具有成活率高、速度快,操作性强、成本低、简单易行的特点,可实现大规模机械化作业,效益显著,为荒漠草原地区生态建设探索出了一条新的有效途径,可在北方干旱、半干旱地区大力推广应用。

Study on the rain-fed cultivation technologies for Ceratoides arborescens cv. Keerqinxing in desert grassland area of Inner Mongolia

Ceratoides arborescens cv.Keerqinxing is a high quality forage cultivar.But it is difficult to sow with machine because of the burrs on seeds,which make the seeds sticked each other.Moreover,the seed germination requests a higher temperature and moisture,so It is also difficulty to establish without irrigation.It is a simple and easy way to grow seedlings first and then to plant with mechine in large scale.The survival rate was high and growth speed was satisfied.It could be concluded that it is a new effective way for ecological construction in the desert grsssland areas of Inner Mongolia,it could be used in the same area in north of China.
