摘要
进行了优质早籼稻赣早籼 37号有机无机复混肥、BB肥、水稻专用复合肥三因素三水平正交试验 ,结果表明 :处理组合以一次性作基肥深施总有效成分为 30 0kg/hm2 的有机无机专用复合肥产量最高。肥料种类处理间产量差异达极显著水平 ,使用有机无机复混肥产量最高 ,BB肥居中 ,两者间产量差异不显著。但均较使用水稻专用复合肥增产极显著。在肥料用量处理中 ,随着复混肥总有效成分增多 ,产量增加 ,高、中施肥水平产量显著高于低肥水平 ,肥料用法处理间差异不显著。最后根据试验结果 ,提出了加大有机无机复混肥。
The orthogonal experiment(three factors and three levels) in the application of compound fertilizer, BB fertilizer and special rice fertilizer into Gan Early-indica 37 with good quality was carried out.The result indicated the compound fertilizer as the basal dressing had the most effectiveity which was significant difference with other two factors. The highest yield was obtained with the application of the compound fertilizer;then, the application of BB fertilizer. There was no difference between the two kinds of fertilizer mentiond above,but there was a significant difference between the two kinds of fertilizas and special rice fertilizer. The yield was increaring with the increase of the amount of the compound fertilizer. There was no significant difference among the application methods of fertilizer. Thus, the suggestions the compound fertilizer and BB fertilizer be widely applied and the best method be used as the basal dressing.
