鲁南地区耐低温饲用燕麦秋播和春播生产性能比较

Comparison of production performance between autumn sowing and spring sowing of low-temperature tolerant fodder oat in southern Shandong

为明确鲁南地区秋播和春播燕麦生产性能的差异,以耐低温品种"枪手"为试验品种,比较第一年秋播和第二年春播对其生长特性、产草量、营养品质和饲用价值的影响。结果显示,与第二年春播相比,第一年秋播在株高、单株叶面积、鲜草产量、干草产量方面具有明显优势。穗、叶片中粗脂肪含量,茎、穗中粗蛋白含量,整株中粗脂肪、粗蛋白和粗灰分含量均有显著提高(P<0.05)。研究表明,在鲁南地区适宜利用冬季农闲田发展饲用燕麦种植。

In order to clarify the difference in the production performance of autumn and spring oat in southern Shandong,the low-temperature-tolerant variety’Gunman’was used as the experimental variety to study the growth characteristics,grass yield,nutritional quality and feed value of autumn sowing in the first year and of spring sowing in the second year.The results showed that compared with the spring sowing in the second year,the autumn sowing in the first year had obvious advantages in terms of plant height,leaf area per plant,fresh grass yield and hay yield,and significantly increased the crude fat content in ears and leaves and the crude protein content in stems and in ears(P<0.05).The crude fat content,crude protein content and crude ash content of the whole plant had been obviously improved(P<0.05).The experiment indicates that it is suitable to use winter slack farmland to develop fodder oat planting in southern Shandong.
