Coupling Effects of Applied Nitrogen,Planting Density on Western Wheatgrass Seed Yield by Model Analysis

WANG Quan-zhen~(1,2),HAN Jian-guo~(2*),ZHOU He~2,LIU Fu-yuan~3,ZHONG Yong~3 (1.Laboratory of Grassland Science,College of Animal Science and Technology,Northwest A&F University,Yangling,Shaanxi,712100,China;2.Institute of Grassland Science,China Agricultural University,Beijing,100094,China;3.Gansu Branch of Chengdu Daye International Interest Co.Ltd,Jiuquan Gansu,735009,China)  
Using a three factors orthogonal experimental design,a model for analysis of coupling effects of applied nitrogen,plant density and PP333 application on seed yield in western wheatgrass,Pascopyrum smithii was established.The analysis results indicated that applied nitrogen was the most important impact factor on western wheatgrass seed yield,planting density and application of PP333 ranked in turn.A kind of synergistic type was demonstrated for the coupling effects of applied nitrogen and planting density on seed yield.The optimum range of the management factors were concluded by frequency analysis as following,planting density from 429×10~4 to 450×10~4shoot/hm~2,application rate of nitrogen from 160 to165 N kg/hm~2,application rate of PP333 from 0.197 to 0.233 a.i.kg/hm~2.
