摘要
为寻求冀北地区燕麦最高生产能力，在以往高产栽培实践经验的基础上，2010～2012年对5个燕麦品种（皮燕麦品种1个、裸燕麦品种4个）进行了连续3 a的高产栽培试验，并于2012年4月燕麦播种前对冀北燕麦产区12个样点的土壤养分含量进行了测定，以明确目前冀北坝上地区的土壤养分状况以及试验品种的生长特性和产量潜力。结果表明：冀北燕麦产区过去“缺磷、少氮、富钾”的土壤肥力状况已经发生了改变，“增施有机肥提高土壤蓄水保肥能力，均衡配方施肥提高燕麦单产”将是今后一个时期燕麦生产的主要工作；参试的5个燕麦品种均表现抗逆性强、丰产性好，早熟或极早熟特性突出；坝莜6号在2012年获得了5494.5 kg/hm2的最高产量。
In order to seek the highest production capacity of oat in north of Hebei Province , based on previous experience of high yield cultivation, the high yield cultivation test of 5 oat varieties （ 1 leather oat variety and 4 naked oat varieties ） has been done from 2010 to 2012, and the soil nutrient contents of 12 points in oat producing areas of north of Hebei Province has been examined before oat sowing in April of 2012 to clear the soil nutrient status in Bashang area of north of Hebei Province and the growth characteristics and yield potential of the test varieties.The results showed that the soil fertility status of lack of N and P , rich of K in oat producing areas of north of Hebei Province has been changed , the main work in the future for a period of oat production will be increasing organic fertilizer to improve soil water storage capacity and balancing fertilization to increase the oats per unit area yield.The test varieties all showed strong resistance, high yielding, precocious or very precocious features prominent, Bayou No.6 with the highest yield of 5 494.5 kg/hm2 in 2012.
