【摘要】 [目的]研究4种常用有机肥在相同氮素条件下对有机水稻生长的影响,为有机稻生产用肥提供理论依据。[方法]在有机稻米栽培模式下,设置不同有机肥种类的处理,分析有机稻的生长农艺性状,了解不同的施肥种类对有机稻生长的影响。[结果]农家收集的单一有机肥养分配比不均衡,分蘖成穗率、结实率较低,产量低于施用化肥处理,但可增加土壤有机质含量,促进土壤的肥力保持。[结论]商品有机肥既有农家肥的保肥特性,又可平衡养分配比,施后各农艺性状优于单一农家肥处理,产量与施用化肥相近,适用于有机稻的生产。更多还原

【Abstract】 [Objective]To study the effect on growth of organic rice with four commonly used fertilizer in the same nitrogen,thus to provide theoretical evidence for fertilizer in organic rice production. [Method]The experimental materials were processed to different kinds of organic fertilizers in organic rice cultivation mode. By analyzing the agronomic traits of its growth,the effects different kinds of organic fertilizers on the growth of organic rice were determined. [Result]The result shows that the single organic fertilizer collected in farm is unbalanced,the rate of tillering,seeding and production were lower than fertilizer. On the other hand,it increases contents of organic matter in soils and keeps the fertility of the soils. [Conclusion]With the advantage in yield and use,the commercial organic fertilizer is more suitable for the production of the organic rice.更多还原
