【摘要】 在21年(1981～2002)长期肥料定位试验的条件下,研究了有机无机肥配施对水稻产量及干物质生产特性的影响,结果表明:不同肥料结构对水稻产量和水稻干物质生产均有显著影响。与长期单施化肥相比,长期有机无机肥配合施用可使水稻产量增加2.69%～11.16%,干物质积累量和群体生长率明显提高(主要在生育后期)。更多还原

【Abstract】 Under the condition of 21 years(1981～2002) located fertilizer experiment, the effects of long-term mixed application of organic-inorganic on the yield and dry matter producing characters of rice were studied. The results showed that the grain yield and dry matter accumulation were significantly influenced by different fertilization combinations. Compared to the chemical fertilizer treatment,the grain yield of the mixed organic-inorganic fertilizer treatment increased by 2.69%～11.16% in 2002,also its dry matter accumulation and the crop growth rate were higher(especially in the late growth stage).更多还原
