摘要
针对阿里地区燕麦传统种植模式存在的问题,本研究设计了12个混播模式,对燕麦+箭筈豌豆混播草地的干草产量、粗蛋白、中性洗涤纤维、酸性洗涤纤维等4个指标进行测定,并应用灰色关联度方法综合评价混播草地的生产性能。结果表明:不同1年生人工草地提质增产模式中,干草产量最高的是同行燕麦与箭筈豌豆混播比例3∶1。燕麦与箭筈豌豆同行1∶3混播模式可明显增加粗蛋白含量,较传统的燕麦单一种植的粗蛋白增幅巨大。通过综合衡量产量、营养各指标,间作1∶2,即种植1行燕麦间种2行箭筈豌豆的模式最好,可作为1年生优质饲草种植模式在藏西地区进行示范推广。
In view of the problems existing in the traditional oat planting model in Aali region,12 mixed sowing models were designed in this study to determine hay yield,crude protein,neutral detergent fiber and acid detergent fiber of Avena sativa+Vicia sativa mixed sowing grassland,and the grey correlation method was applied to comprehensively evaluate the production performance of mixed sowing grassland.The results showed that the maxi⁃mum hay yield was found under the Vicia sativa mixed sowing ratio of 3:1 among the different annual artificial grassland improvement and increase modes.The crude protein content of oats and Vicia sativa mixed sowing model 1:3 was significantly increased,compared with that of the traditional oat monoculture.According to the comprehensive measurement of yield and nutrition indexes,the Vicia sativa mixed sowing model of 1 row and 2 rows was the best,which could be used as an annual premium forage planting model in western Tibet for demonstration and promotion.
