摘要
在大田条件下研究了不同氮肥处理对饲用玉米子粒和秸秆产量及品质的影响。结果表明：在施纯氮0-450 kg/hm^2的范围内,随施氮量增加,玉米子粒和秸秆产量增加。当施氮量为375 kg/hm^2时秸秆产量最高,当施氮量为450 kg/hm^2时子粒产量最高。施氮量超过450 kg/hm^2时,经济效益下降;随着施氮量的增加,秸秆粗蛋白含量逐渐上升,中性洗涤纤维、酸性洗涤纤维含量逐渐下降,半纤维素和纤维素含量呈下降趋势,改善秸秆品质。
The effect of different nitrogen treatment on yield and quality of forage maize seed and straw stalk was investigated under the condition of the yield.Field test results show that when applying pure nitrogen 0～450 kg/hm^2,yield of maize seed and straw stalk was increased.When applying pure nitrogen 375 kg/hm^2,yield of straw stalk was the highest.When applying pure nitrogen 450 kg/hm^2,seed yield was the highest.When applying pure nitrogen over 375 kg/hm^2,economic efficiency will drop.With increasing of applying nitrogen,crude protein concentration was increased,neutral detergent fiber and acid detergent fiber concentratiom were decreased,cellulose and hemicellulose concentration were decreased,straw stalk quality was improved.
