摘要
在甘肃天祝的燕麦栽培技术研究表明:引进品种比当地品种增产1～3倍;播量为187 5～225 0kg/hm2比150 0kg/hm2的抽穗期刈割产量高8 1%～12 8%,混播比单播增产24 82%～35 44%;燕麦覆膜后分蘖增加60%,增产55%;以青干草为目的的适宜播期为5月20日～6月4日,以收种为目的的播期不得迟于5月15日。
The research carried out in Tianzhu county,results indicated that: a) the yield of introduced oat variety was 1～3 times higher than that of local varieties;b) the grass yield increased by 8 1% to 12 8% while the sow rate between 187 5 kg/hm 2 to 225 0 kg/hm 2 compared with the rate of 150 0 kg/hm 2; c) compared with hole sowing,the yield of mixture with legume increased by 55%; d) the suitable sowing date should be between 20 May to 4 June while the oat was used for hay,and it should not be sown late than 15 May if the purpose was for seed
