摘要
文章以国家牧草体系宁夏综合试验站试验地所种植的第二茬紫花苜蓿(金皇后)为试验材料,在其初花期刈割,并按照不同含水量、不同密度、不同CaO添加量进行打捆,贮藏360 d,定期取样。对不同处理草捆各贮藏期的样品进行霉菌数量和降解率测定,从而确定最适含水量、打捆密度、CaO添加量,为苜蓿草捆安全贮藏提供可靠的试验依据。通过试验数据分析得知,处理5(含水量为20%,打捆密度为150 kg/m3,CaO添加量为2%)贮藏期内霉菌数量最少,消化特性最好。
This paper take the second crop grown alfalfa （gold queen） of the national grass system comprehensive test station as the test material and cut in its initial flowering cradles.According to the different water content,different density and different additive amount of CaO for bundling,and storaging 360 days,then regular sampling.By dynamic measuring the mould quantiry and digestive rate of different processing bale during the storage period to determine the optimum water content,bundling density,additive amount of CaO for alfalfa bundle of safety wtorage provide reliable experimental basis.The mould number of treatment 5（moisture conntent is 20%,bundling density for 150kg/m^3.adding 2% CaO）during processing storage period is the least.
