摘要
为了大面积推广农区耕地复种优良牧草箭筈豌豆,笔者在青海东部农区进行了不同地区不同海拔范围的最佳播量种植筛选试验。结果表明,在青海省东部农区1700m^4300m海拔范围内种植饲草型箭筈豌豆的最佳单播播量为90kg/hm2~120kg/hm2。
For large scale cultivation of multiple cropping forage - vetch,the article got on the best seeding amount planted screening test of technical support for the project. different areas at different altitudes range in Qinghai agricultural areas through The results showed that, the best Unicast Seeding Amount rate is 90kg/hm^2 120kg/hm^2 of Planting vetch in the eastern part of Qinghai agricultural area 1700m - 4300m altitude range.
