一年生饲用燕麦与豌豆混种最佳刈割期的研究

The Studies on the Optimal Mixture Harvest Time of Annual Forage Oat and Pea

通过对高寒地区燕麦与豌豆混播草地五种播种比例三个不同刈割期的产草量、粗蛋白质含量及产量、中性洗涤纤维 (NDF)、酸性洗涤纤维 (ADF)含量动态研究 ,结果证明 ,燕麦单播及其与豌豆混播的最佳刈割期应为燕麦乳熟末期至蜡熟早期 ,豌豆下部豆荚全充满时期 ,此时刈割其粗蛋白产量和产草量最高 ,而NDF。

The dynamical studies on yield, quality of oat(Avena sativa) and pea(Pisum sativum)in both monoculture and mixture (five seeding rate ,three harvest time)were conducted in high cold area. The results indicated that the late milk stage early dough stage of oat and the pods filled stage of pea in the mixture was the best time for harvesting because of the highest CP, DM yield and lower NDF and ADF contents.
