青海大通县燕麦和豌豆混播对饲草产量和质量影响对比试验

OATS AND PEAS MIXED BROAD CAST COMPARISON TEST ON FORAGE YIELD AND QUALITY IN QINGHAI DATONG COUNTY

以燕麦林纳和饲用豌豆青建1号为试验对象,在青海省大通县通过一年生禾豆饲草不同混播比例进行小区试验,对饲草物候期、产量、营养成分等指标进行研究。结果表明:综合各项指标,本次试验中燕麦与饲用豌豆在7:3的混播比例下,鲜干草(鲜草:93371 kg/hm^(2),干草:29084 kg/hm^(2))和蛋白产量(3353.38 kg/hm^(2))较高,鲜干比(3.21:1)适中,因此,是该地区开展一年生禾豆混播饲草地生产的较优比例。

oat linna and forage pea green building No.1 were used to study phenology,yield and nutrient composit ion in Datong County,Qinghai Province.The results show that at the 7:3 mixed sowing ratio,fresh hay(fresh hay:93,371 kg/hm^(2),hay:29,084kg/hm^(2))and protein yield(3353.38kg/hm^(2))were high,and fresh dry ratio(3.21)was moderate,which is the better proportion of annual mixed sowing forage production in this area.
