摘要
采用完全随机区组设计,在低氮条件下比较分析燕麦与苜蓿不同间作与混播模式的生产效应,研究了燕麦和苜蓿间作混播对牧草产量和品质的影响。结果表明,各混播处理对混合牧草的株高、鲜干比、茎叶比几乎没有影响;间条播优于混条播,燕麦与苜蓿3∶1更具优势;在燕麦乳熟期进行刈割,所有处理中T1(燕麦与苜蓿3∶1间条播)的干草产量(457g/m2)和粗蛋白产量(38.44g/m2)均最高,分别比单播燕麦增产12%和8.6%。
According to complete randomized block design, the experiment was carried out to study the effects of intercropping and mixture modes on forage yield and quality of oat and alfalfa in Yangling town of Shanxi Province. A total of six different modes were analyzed under low soil nitrogen environment. The results showed that the mixture treatments almost have no effect on the height,FW/DW and stalk/leaf of the mixture forage. The mode of intercropping is better than that of mixture and the oat and alfalfa at 3 : 1 is the best combination. At this condition,the dry forage yield and crud protein of oat and alfalfa were the highest by mowing at milk stage of oat. Compared to oat monoculture,the best planting mode was intercropping of oat and alfalfa at 3 ; 1 by which dry forage yield 457g/m^2 and crud protein (38.44g/m^2)were increased by 12% and 8.6 %, respectively.
