试验结果表明,施用含有木质素复合肥处理的水稻产量最高,达637.85kg/667m2,显著高于高浓度、低浓度复合肥处理。施用含有木质素复合肥处理的生物量生产、经济系数、氮素积累量和氮肥利用效率等各项指标都要好于其它处理,经济效益最高达339.24元/667m2。说明施用木质素复合肥可延缓养分的释放,促进水稻对养分的吸收,提高肥料利用率,具有一定的增产效果,从而提高水稻的经济效益。

The results showed that the highest yield of rice treated with lignin compound fertilizer was 637.85kg / 667m2, which was significantly higher than that of high concentration and low concentration of compound fertilizers. The biomass production, economic coefficient, nitrogen accumulation and nitrogen use efficiency of the treatment with lignin fertilizer were all better than those of other treatments, and the economic benefit was up to 339.24 yuan / 667m2. It shows that the application of lignin compound fertilizer can delay the release of nutrients, promote the absorption of nutrients in rice, improve fertilizer utilization, with a certain yield-increasing effect, thereby increasing the economic benefits of rice.
