畜牧业的迅速发展,只靠放牧养畜和精料养禽的传统饲养方式已不能满足生产发展的要求,走种草养禽之路是大势所趋。选择优良的草种是种草养畜的重要一环。苦荬菜(lactuca indica L.)在内蒙古种植证明,是一种高产优质的青饲料,采食利用率率适口性好。但它生育期为160～180天,初引入内蒙时,绝大多数地区不能开花结实,而且种子寿命短,不能长期贮存,因而限制了这一高产优质的青饲料在内蒙地区推广应用,为解决这一问题,内蒙古农牧学院草原系已选育出能在内蒙地区开花结实的早熟苦荬菜品种.该品种两年来在内蒙许多地区如巴盟五原、杭后、临河、伊盟前旗伊旗,乌
With the rapid development of animal husbandry, the traditional rearing methods of grazing livestock and concentrate poultry can no longer satisfy the requirements of production and development. The road to planting grass and poultry is the trend of the times. Select good grass species is an important part of grass and livestock. It is proved that lactuca indica L. is planted in Inner Mongolia. It is a high-quality and high-quality green fodder, and its feed intake utilization rate is good and palatability. However, its growth period is 160-180 days. When it was introduced into Inner Mongolia at the beginning, the vast majority of regions could not flowering and fruiting, and the seeds had short life span and could not be stored for a long time, thus limiting the promotion and application of this high-quality and high-quality green fodder in Inner Mongolia. A problem, grassland Department of Agriculture and Animal Husbandry in Inner Mongolia has bred a variety of early maturing bitter can flowering in Inner Mongolia in the past two years in many areas in Inner Mongolia, such as Bamei five Yuan, Hangzhou, Linhe, Yiqianqianqi Iraq Flag, Ukraine
