| 摘 要： | 通过“3414”回归最优设计原理设置的早稻肥效试验,研究配方施肥对早稻农艺性状和产量的影响。试验结果表明：与对照（CK）相比,各配方施肥处理水稻有效穗、结实率、千粒重、实际产量均有所提高,其中以施纯氮13kg/666.7m^2、纯磷4kg/666.7m^2、纯钾9 kg/666.7m^2时,水稻农艺性状较其它处理好,且实际产量比CK增加55.2%,为本试验条件下最佳配方施肥组合。

| Abstract: | An experiment was carried out to study the effect of formulated fertilization on agronomic characters and yield of rice(Oryza sativa) according to the theory of 3414 regression optimum design,the results show that,the effective spica,fructification rate,thousand-grain weight,and actual yield of each fertilizer treatment was enhanced by comparing with CK,otherwise,while fertilizing pure N 13 kg/666.7m2,P 4 kg/666.7m2,K 9kg/ 666.7m2,the agronomic characters of rice were better than other treatments,and also i... |
