摘要
为缓解西藏豆科饲草供给不足,提高单位面积饲草生产性能,本文对拉萨引进的青海444燕麦与兰箭系列箭筈豌豆不同栽培模式开展研究。研究表明:青海444燕麦与兰箭系列箭筈豌豆混播最优亩播种量:12 kg燕麦+6 kg箭筈豌豆,其中燕麦(12kg/667m^2)+兰箭3号(6 kg/667m^2)鲜草产量为4433. 55 kg/667m^2;相同播量兰箭系列箭筈豌豆单播种子产量:兰箭2号>兰箭3号>兰箭1号,兰箭2号和兰箭3号产量均表现良好且产量接近,其中兰箭2号种子产量81. 82 kg/667m^2。
The purpose of this experiment was to research the different cultivation models of introduced Qinghai 444 Oats and Lanjian Common Vetch in Lasa,in order to relieve the insufficiency of leguminous forage and to raise production performance per unit. The results showed that the optimum sowing quantity per 667 m^2 was 12 kg Oats + 6 kg Vicia sativa,and the fresh forage yield of oats and No. 3 Lanjian Vicia sativa reached 4433. 55 kg/667 m^2;The seed yield for Lanjian Vicia sativa on same single-sowing quantity was No. 2 > No. 3 > No. 1,and the No. 2 and No. 3 had good performance and similar yield,the seed yield of No. 2 reached 81. 82 kg/667 m^2.
