摘要
依据黑龙江省的气候特点和牧草种植需要,用紫花苜蓿与无芒雀麦、扁穗冰草分别进行混播试验,对混作复合群体与三种牧草单播时在形态、产量、营养品质、饲用价值等方面进行比较分析,探讨紫花苜蓿与这两种不同禾本科牧草混作后的增产效益。结果表明,混播群体较禾本科单播群体草地利用效益分别提高12.71%和23.13%,牧草产量分别提高7.27%和15.46%,混播既便于牧草贮藏与利用,又可提高牧草的饲用价值,获得较好的经济效益。
Based on characteristics of the climate and the needs of forages in Heilongjiang Province,the mixed seeding alfalfa with smooth bromegrass and with crested wheat grass was conducted,the shape,yield,nutritional quality,feed value were analyzed to study the effect on yield increase.The results showed that the grassland use efficiency in mixed seeding population was increased by 12.71% and 23.13% than clean culture population of gramineous pasture respectively,yield was increased by 7.27% and 15.46% respectively,mixture sowing not only was convenient for storage and utilization of forage,but also improved the feeding value of pasture.As the result,better economic benefit can be gained.
