不同播种时期对高原家庭牧场“圈窝子”燕麦生产特性的影响

Effect of different treatment of seeding date on growth character of oat in winter pen of family ranch on Qinghai plateau

研究了 5种播种时期处理分别是 13/ 5、2 3/ 5、2 / 6、12 / 6和 2 2 / 6(日 /月 )对家庭牧场“圈窝子”燕麦 ( YTY品种 )生长特性及营养成分的影响。结果表明高原家庭牧场“圈窝子”内土壤营养成分的含量能够充分满足燕麦的生长需要。随燕麦播种时期的推后 ,其生育期逐步提前结束。为获得较高的燕麦青干草和粗蛋白质产量 ,播种时间应早于 5月 13日。随播种时期的推后燕麦粗蛋白质 ( CP)的含量呈逐步增加的趋势 ,粗纤维 ( CF)则呈明显下降的趋势。家庭牧场“圈窝子”内是种植燕麦收获青干草最理想的地方。

The paper studied different seeding date treatments (13/5、23/5、2/6、12/6 and 22/6 day/month) on growth character and nutrient content of oat (introduced YTY variety from Finland) in winter pen of family ranch on Alpine. The results showed that date of seeding oat should be earlier than 13th May for highest yields of green dry herbage and crude protein. The oat’s generational period on different treatment ended early as seeding date delaying, and the crude protein yield increased but the crude fiber decreased. The winter pen of family ranch is a ideal oat planting place for green herbage.
