| 摘 要： | 2008年在内蒙古西辽河平原灰色草甸土上,采用"3414"二次回归最优设计试验方案,研究施肥对不同品种紫花苜蓿的产量效应及营养物质含量的影响。研究结果表明,紫花苜蓿产量最高的施肥方案为N 0 kg/hm2、P2O5 63.56 kg/hm2、K2O 110.00 kg/hm2,并筛选出WL-232HQ为适宜通辽地区种植的最佳苜蓿品种。同时分析不同施肥水平对紫花苜蓿营养物质含量的影响,14个处理组合中,处理N0P2K2、N1P1K2、N2P2K0、N2P1K2和N2P2K3是试验条件下获得粗蛋白含量较高的组合。

| Abstract: | Using 3414 quadratic regression optimum design,the effects of N,P,K mixed fertilizing on fresh forage yield and nutriention on alfalfa(Medicago Sativa)was conducted through orthogonal test from May to September in 2008 in Inner Mongolia.The results indicated that the best fertilization design was N 0 kg/hm2,P2O5 63.56 kg/hm2 and K2O 110.00 kg/hm2.And we screen out alfalfa of WL-232HQ as the most suitable planting variety for Tongliao region.At the same time analysied the effect of different fertilizer levels impact on nutrition constituent of alfalfa,the higher crude protein content was obtained with the fertilizer application treatment of N0P2K2,N1P1K2,N2P2K0,N2P1K2,N2P2K3. |
