chinois. 采用二因素D-饱和最优设计,通过猫尾草拔节-抽穗期的根氮、磷、钾和茎叶氮、磷、钾的含量对其种子产量和产量因子进行灰关联熵分析。结果表明,在猫尾草拔节-抽穗期,植株氮磷钾含量对猫尾草种子产量的影响顺序为钾磷氮;茎叶含钾量和根含钾量对产量因子小穗数/生植枝影响最大;根含氮量对产量因子种子粒数/小穗和单粒种子重影响最大;根含氮量和茎叶含钾量对产量因子生植枝数/m2影响最大。

Based on 2-D-optimum orthogonal design field experiment in the jointing-heading period of Phleum pratense L.,the results show that potassium content is the most productive on the seed yield,phosphorus comes next and nitrogen the least.The potassium is beneficial to the development of spikelet,and the nitrogen is useful to burliness and future seed growth after grey relation entropy analysis.
