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 introduction of 24 kinds of excellent forage grass in the North Sea State in Haihai for two years of different sowing plot cultivation experiments. The results showed that sowing in spring was more conducive to the growth and development of all kinds of forage grass and overwintering survival rate of forage grass than sowing in summer. Progeny seeding was feasible for some grasses and had a better performance than the spring sowing date. By observing and analyzing the growth and development of various forages and comparing their performance in winter performance and yield, nine species (varieties) suitable for popularization in some parts of the country were selected and identified.
