为探索提高高海拔地区混播草地草产量的施肥方式,选用自制有机肥+化肥和单施化肥两种方式研究燕麦和箭筈豌豆混播草地的生产性能.结果表明:施用自制有机肥+化肥的混播草地鲜草产量显著高于单施化肥的鲜草产量( P<0.05 ),鲜草产量68 505 kg/hm2,仅施用化肥鲜草产量为57,500万kg/hm2,证明有机肥对持续提高高海拔地区混播草地牧草产量有积极的作用.

To improve the mixture grassland yield capacity in high altitude region,the production per-formance of mixed sowing grassland of Oat and Common Vetch by applying for homemade organic fertilizer mixed with chemical fertilizers and individual chemical fertilizers respectively were studied. The results showed that fresh grass yield in mixed sowing grassland of homemade organic fertilizer mixed with chemical fertilizers is significantly higher than in the individual chemical fertilizers grass-land (P<0.05).The fresh grass yield reach 68 505 kg/hm2,but the fresh grass yield in individual chemical fertilizers grassland reach 57 500 kg/hm2 .It indicated that organic fertilizer has positive effect on improving the grass yield in mixed sowing grassland in high altitude region.
