为了研究不同施肥处理对谷稗的生物量及品质的影响,以‘朝牧一号'稗子为试验材料,设置4种施肥方式（A有机肥、B有机肥+无机肥、C无机肥、D不施肥）。收集样品后,用烘干恒重的方法测得谷稗生物量的数据。结果表明,处理C的生物量为871 g/m²,比A、B和D处理分别增加了27.2%、11.9%、56.6%;处理C的粗蛋白含量为10.38%,分别比处理A、B和D增加了19.8%、2.9%、13.2%;B处理的谷稗粗脂肪含量为1.29%,比D处理减少了60.3%;D处理的谷稗酸性洗涤纤维(ADF)和中性洗涤纤维(NDF)最低,分别为35.11%和66.11%。在4种施肥方式中,以有机肥+无机肥处理的综合表现较好。本研究结果为东北黑土区高产优质谷稗栽培技术的制定奠定了理论基础。

In order to explore the effects of different fertilization treatments on the biomass and quality of barnyard grass, 4 fertilization treatments were set up (A: organic fertilizers, B: organic fertilizers + inorganic fertilizers, C: inorganic fertilizers, and D: no fertilization) with ‘Zhaomu No.1' as material. After collecting the samples, the biomass of barnyard grass was measured by drying constant weight method. The results showed that the biomass of treatment C was 871 g/m², which was 27.2%, 11.9% and 56.6% higher than that of treatment A, B and D. The crude protein content of treatment C was 10.38%, which was 19.8%, 2.9% and 13.2% higher than that of treatment A, B and D. The crude fat content of treatment B was 1.29%, which was 60.3% less than that of treatment D. The content of acid detergent fiber (ADF) and neutral detergent fiber (NDF) of treatment D were the lowest, 35.11% and 66.11% respectively. Among the 4 fertilization treatments, organic fertilizers + inorganic fertilizers had better comprehensive performance. The results of this study can lay a foundation for formulating proper cultivation techniques for high-yield and high-quality barnyard grass in the black soil area of northeast China.
