河南县圈窝子一年生人工草地混播及牧草产量测定

在河南县优干宁镇的阿木乎村,实施了燕麦与箭筈豌豆圈窝子混播种植。通过混播这种方式,一方面提高了一年生人工草地的产草量,平均产鲜草为43 560.3kg/hm2,比当地燕麦单播多产鲜草17 560.2kg/hm2,提高67.54%,干草多产5 299.48 kg/hm2,提高52.79%。混播燕麦比当地单播燕麦株高高15.7cm,重量提高0.86kg,明显提高产草量和牧草品质;另一方面改善草地质量,增加牧户冷季饲草的储备。

Study On Mix Sowing of Annual Artificial Grassland in Fence of Henan County and Forage Yield Determination

A study on mix sowing in fence of Oat （Avenasativa L. ） and Common Vetch （ Vicia sativa L. ） has been conducted in Ahumu villages Youganning town, Henan county. The result showed that it can increased the forage field of annual artificial grassland by this mix sowing method. The average fresh grass yield of mix sowing Oat and Common Vetch was 43560.3kg/hm2, it was 17560.2kg/hm2 more than local single Oat and increase by 67.54%. The hay yield of mixture grassland was 5299.48 kg/hm2 more than single grassland, grass increase by 52.79%. The plant height of mixture grassland was 15.7cm higher than local single grassland and the weight also increased by0.86kg. The yield and qulity of forage were significantly enhanced. Moreover, the qulity of grassland has been improved and the forage grass store for herd family in cold season has been increased by this mix sowing method.
