摘要: 为探究肥料高效利用对紫花苜蓿(Medicago sativa L.)高产优质的影响,推动饲草生产提质增效,本试验在内蒙古土默特平原,采用2因素3水平试验方法,分别设置60 kg·hm-2(N1)、90 kg·hm-2(N2)和120 kg·hm-2(N3)的氮肥水平,40 kg·hm-2(P1)、80 kg·hm-2(P2)和120 kg·hm-2(P3)的磷肥水平,检测不同水平氮磷施用对紫花苜蓿生产性能和干草饲用价值的影响。结果显示:不同氮、磷水平配施对苜蓿产量及饲用品质相关指标存在不同程度的促进作用,与对照(不施肥)相比,株高、茎粗、干草产量的增幅分别为2.88%~28.74%,4.74%~20.16%,17.63%~24.36%,N2P3处理下饲草产量最高;粗蛋白含量及相对饲喂价值的增幅分别为4.13%~8.78%,4.51%~6.12%。隶属函数综合评价表明,N3P1(120 kg·hm-2氮肥,40 kg·hm-2磷肥)处理下苜蓿品质表现最好,研究结果将为苜蓿高产优质提供理论依据和实践指导。

Abstract: In order to explore the impacts of efficient utilization of fertilizer on the high yield and high quality of alfalfa, promote the quality and efficiency of forage production. This experiment was set up in the Tumd plain of Inner Mongolia. A two-factor and three-level test method was used to set the nitrogen fertilizer levels of 60 kg·hm-2 ( N1 ), 90 kg·hm-2 ( N2 ) and 120 kg·hm-2 (N3), and the phosphorus fertilizer levels of 40 kg·hm-2 (P1), 80 kg·hm-2 (P2) and 120 kg·hm-2 (P3). The effects of different levels of nitrogen and phosphorus application on the production performance and hay feeding value of alfalfa were detected. The results showed that the combined application of different nitrogen and phosphorus levels had different degrees of promoting effects on alfalfa yield and forage quality related indicators. Compared with the control ( no fertilization ), the plant height, stem diameter and hay yield were increased by 2.88 %-28.74 %, 4.74 %-20.16 % and 17.63 %-24.36 %, respectively, and the forage yield was the highest under N2P3 treatment. The increase of crude protein and relative feeding value were 4.13 %-8.78 % and 4.51 %-6.12 %, respectively. The comprehensive evaluation of membership function showed that the quality of alfalfa was the best under N3P1 (120 kg·hm-2,40 kg·hm-2) treatment. The results will provide theoretical basis and practical guidance for high yield and high quality of alfalfa.
