摘要
试验探索了前作(冬季)种植蔬菜的情况下,不同氮磷肥施用量与配施植物/土壤调理剂对水稻产量和产量性状的影响。研究结果表明,水稻产量与N、P肥施用量呈抛物线型关系,土壤植物调理剂在提高水稻N、P肥吸收利用率方面效果显著。本试验条件下,667m2施N5.9kg+P2O54.1kg+K2O5kg+土壤植物调理剂33kg,能获得高产。对于高需N、P品种,在合理施肥的同时配合使用土壤植物调理剂能充分发挥其产量优势。
To explore suitable application of nitrogen and phosphate fertilizer in rice production and methods of increasing absorption and use efficiency of N and P in rice plants, the experiment of nitrogen and phosphate levels was conducted in Bishan of Chongqing. The results showed that there was a parabola relationship between rice yield and the application rate of N, P fertilizer; The effect of soil/plant conditioner was remarkable in increasing absorption and use efficiency of N and P in rice plants. Under this experiment condition, the high yield was obtained in treatments which amounts of fertilizers and soil/plant conditioner application were as follows： 5.9 kg/667 m2 of nitrogen, 4.1 kg/667 m2 of phosphate, 5 kg/667 m2 of potassium and 33 kg/667 mE of soil/plant conditioner. Rational fertilization and application of soil/plant conditioner could obtained the high yield in rice varieties which great demand for nitrogen and phosphate fertilizer.
