四川盆西平原一季中稻最佳肥料效应研究

通过两个供试地点的不同施肥方式试验,研究了四川盆西平原一季中稻最佳肥料效应。结果表明,均衡施用氮、磷、钾肥以及锌肥（NPKZn）能显著提高水稻产量,有机、无机肥料合理配施（30%有机肥＋70%化肥）能促进水稻增产;同时,这2种施肥方式有利于水稻产量结构的优化。从农学效应看,两地无论地块肥力高低,Zn的农学效应最高,而N肥增产率最高。从单一元素看,不论试验地点和田块肥力高低,缺N处理显著降低水稻产量,说明施用N肥是提高水稻产量的重要措施。...

To study the optimum fertilizer effect on single cropping rice,a field experiment was conducted with different fertilization methods at two experimental sites in west plain of Sichuan Basin. Results showed that,rice yield was significantly increased by balanced fertilization of Nitrogen（ N）,Phosphate（ P）,Potassium（ K） and Zinc（ Zn）,Organic（ 30 %） and inorganic（ 70 %） fertilizer could promote rice production. These two fertilization methods were conducive to optimizing the yield structure of rice. No matter how the fertility level of the two experimental sites was,agronomic agronomy efficiency of Zn was the highest,and yield increase rate was the highe
