氮磷肥互作对猫尾草种子产量的效应
Effect of interaction of nitrogen and phosphorus on Phleum pratense L.seed yield
【摘要】 采用二因素D-饱和最优设计方案,建立回归模型并进行效应解析后表明,磷对猫尾草种子产量的影响大于氮;氮磷肥互作对猫尾草种子产量有协同效应;猫尾草种子最高产量氮磷比为N∶P2O5=1∶0.54。
【Abstract】 Based on 2-D-optimum orthogonal design and model analysis, the effect of phosphorus was stronger than that of nitrogen on the seed yield of Phleum pratense L., and interaction of nitrogen and phosphorus produced synergetic effect on the seed yield. When the optimum ratio was N:P2O5=1:0.54, the seed yield was the highest.
