【摘要】 研究了长期施肥对水稻产量及其生理特性的影响。结果表明,有机-无机肥料配施与单施化肥相比,不仅可以提高水稻孕穗期光合产物的形成和积累同化物的能力,有利于水稻颖花的形成,从而提高水稻产量,其增产幅度达2.7%~11.2%,而且还能提高叶绿素的含量,延缓叶片衰老。更多还原

【Abstract】 Effects on rice yield and physiological characteristic that this text studied after long-term application of fertilizers.The results showed that organic-inorganic fertilizer combined application.It could improve rice boot stage shut forming and accumulation of result assimilate the ability of the thing only not merely,help the forming of the rice tip flower,improve rice output.It increased production range up to 2.7%～11.2%,and still could raise the content of the chlorophyll.It was old and feeble to delay the blade.更多还原
