中文摘要：
林纳（Avena sativa L.cv.LENA）是优质燕麦品种之一。本研究比较不同播种量（150、225、300kg/hm2）、行距（20、30、40cm）和肥料（尿素、复合肥、有机肥）对林纳燕麦干草产量、株高和叶绿素相对含量（SPAD值）的影响。结果显示：播种量225kg/hm2,行距40cm的林纳燕麦干草产量最高（P〈0.05）,为8683.5kg/hm2,叶绿素相对含量也相对较高;施用复合肥和尿素能显著提高林纳燕麦干草产量,也有利于燕麦保持较高的叶绿素相对含量。
英文摘要：
Avena sativa L.cv. LENA is one of oats varieties with high-quality.The effect of different seeding rate （150,225,300kg/hm2）, rowlege （20,30,40cm） and kinds of fertilizer（urea,compound fertilizer, organic fertilizer ）on hay yield, plant height and SPAD value of Avena sativa L.cv. LENA were studied.The result shows：the highest oat＇s yield of dry green herbage under the treatment of 225kg/hm2 seeding rate 40cm row spacing was 8 683.5kg/hm2 （p 〈0.05）, the SPAD value was aslo higher than other treatment. The compound fertilizer and urea can not only significantly improve Avena sativa L.cv. LENA hay yield, but also to keep higher SPAD value.
