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

摘要

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 seed-ing oat should be earlier than 13th May for highest yields of green dry herbage and crude pro-tein. The oat's generational period on different treatment ended early as seeding date delay-ing, 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.%研究了5种播种时期处理分别是13/5、23/5、2/6、12/6和22/6(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。
