水稻水肥耦合田间试验的设计、方差分析及多重比较

orrect experimental designing and statistical methods are of vital significance for raising the level of field trials, analyzing the results scientifically, providing accurate information for readers and increasing the recurrence of such trials. Currently, the vast majority of field trial results using various analysis software (such as the DPSS, DPS, SAS, Excel, etc.) to analyze. Although it is convenience, most people do not understand the meaning. It is unable to find a good law and guide production. In this paper, the author used both the methods of randomized block and split plot to design the water and nitrogen coupling field trials of rice. And analyzed and compared the production.
