【摘要】 通过产量构成因素相关分析可知，产量与产量构成因素之间呈显著正相关，求得有机肥、氮、磷、钾不同配比下的水稻生产最优模型，适用于以障碍型冷害为主的年份，最高产量的最优配比为２９１ ．５∶２ ．３∶１∶１．９ ．更多还原

【Abstract】 With yield structure correlation analysis,get across yield and yield structure representation positive correlation,optimized high yield mathematical model of the rice yield was established under disturbance type chill,best of all proportion of tiptop yield is 291.5∶2.3∶1∶1.9.更多还原
