摘要：

为了解施氮量、种植密度和播种方式对‘白燕2号’燕麦农艺性状和产量的影响。采用L8(4×22)正交试验，设施氮量、密度和播种方式3个因素。其中，施氮量因素设4个水平，密度和播种方式每个因素设2个水平，开展试验。结果显示，‘白燕2号’燕麦的抽穗期随施氮量的增加而提前，随种植密度的增加而推迟；株高、节数、穗长以及穗重均随施氮量的增加呈现先增加后降低的趋势；小穗数随播种方式的不同而发生改变。研究表明，播种方式是影响‘白燕2号’燕麦产量的主要因子，其次是施氮量，再次是种植密度，产量以组合A2B1C1最高，达4083.54 kg/hm2，其次为组合A1B1C1，产量为3880.19 kg/hm2，不同施氮量、种植密度和种植方式对‘白燕2号’燕麦产量不显著，但以施氮量52.5 kg/hm2和37.5 kg/hm2、种植密度285万株/hm2和条播组合的产量第一和第二，因此最优组合取A2B1C1或A1B1C1。本研究为‘白燕2号’燕麦高产优质种植技术提供科学依据。

Abstract:

To understand the effects of nitrogen application, planting density and sowing method on the agronomic traits and yield of 'BaiYan No. 2' oat, the L8(4×22) orthogonal experiment was conducted with three factors, nitrogen application rate, density, and sowing method. The application rate factor had four levels, while density and sowing method each had two levels. The results showed that the heading date of 'BaiYan No. 2' oats was advanced with the increase of N application rate and delayed with the increase of planting density. Plant height, number of nodes, panicle length and panicle weight all increased first and then decreased with the increase of nitrogen application rate. The results showed that the sowing mode was the main factor affecting the yield of 'Bai Yan No. 2' oat, followed by nitrogen application rate and planting density. The yield of combination A2B1C1 was the highest, reaching 4083.54 kg/hm2, followed by combination A1B1C1, the yield was 3880.19 kg/hm2. The yield of 'Bai Yan No. 2' oats was not significantly affected by different nitrogen application rates, planting densities and planting methods, but the yield of the combination of nitrogen application of 52.5 kg/hm2 and 37.5 kg/hm2, planting density of 2.85 million seedling/hm2 and strip seeding was first and second, so the best combination was A2B1C1 or A1B1C1. This study provided scientific basis for high-yield and high-quality oat planting technology of 'Bai Yan No. 2’.
