摘要
2008年以来,在吉林西部松嫩平原国有草原进行公农1号紫花苜蓿耕种试验。本文分别对3个不同播种行距的苜蓿生产能力进行了研究,结果表明:公农1号紫花苜蓿人工草地在吉林西部的适宜行距为30cm^45cm;同时还进行了根瘤菌接种试验,经调查,接种区的公农1号紫花苜蓿当年植株的平均高度和干草产量比对照增加14.6%和32.4%,增产效果明显,根瘤菌接种是一项值得推广应用的实用技术。
Base on the farming experiment of the state-owned grasslands in Songnen Plain,2008~2010.In this paper,the three different rows spacing of alfalfa seed production has been studied,the results showed that： Public 1,the appropriate spacing of the Alfalfa planting is 30cm-45cm,in western Jilin.We also conducted the Rhizobium inoculation.After investigation,in the vaccination area,the average plant height of alfalfa and hay production increased by 14.6% and 32.4%,the Crop yields increased significantly,this is a worthy application of practical technology.
