【摘要】 利用冬闲田种植一年生饲草或饲料作物,是解决南方粗饲料不足的主要途径。本研究利用冬闲田种植大麦(Hordeum vulgare),研究其不同刈割期的产量、营养价值和青贮发酵品质。研究结果表明:大麦的干物质产量随生育期的推进逐渐提高,但乳熟期相对饲用价值和干物质消化率显著高于其他生育期(P<0.05),分别为107.19和63.84%。随着生育期的推进,全株大麦青贮发酵品质显著提高。更多还原

【Abstract】 Planting annual forage crops in winter fallow fields is a main way to solve the problem of roughage shortage in the southern China.In this paper,the yields,nutritive value and fermentation quality of barley(Hordeum vulgare L.) were studied.The main results were as follows:Dry matter yield of barley increased with the maturity.Relative feed value and dry matter digestibility of barley at milk stage were 107.19 and 36.84%,respectively,significantly higher than those at other stages(P<0.05).The fermentation quality of barley silage became better and better with the maturity.更多还原
