摘要
引进24种优良牧草在海北州西海镇进行了为期两年的不同播期小区种植试验。结果表明:春季播种比夏季播种更有利于各种牧草的生长发育和提高牧草的越冬成活率,临冬寄籽播种对部分禾本科牧草是可行的且比春季播种生长当年有更优异的表现。通过对各种牧草生长发育状况的观测和分析,比较其在越冬性能和产量方面的表现,选择确定了9种适宜在本地部分地区推广种植的草种(品种)。
The 24 kinds of eximious grazing is introduced and planted for 2 -years in the Xihai town, Haibei.The experiment is constituted from different seedtime. Result shows： the spring seeds is more than seeds in summer to grow - develop of various grazing and exalted to live rate of over winter. Close - winter deposit seeds is viable to parts of Gramineal grazing, and it grows to compare the spring first year dibble growth that year has the more excellent performance. Pass to develop the condition to prognosticate and analyze to various grazing growth, compare it at more the function of winter and the performance of the yield, made sure 9 species that feat grow in the native parts of regions.
