| 摘 要： | 以混推复垦地为研究对象,通过对土壤养分的变化、作物长势和产量(生产力)及其经济效益进行分析比较,结果表明,增施有机肥量为18500,11000kg/hm2时,不论增施1年还是2年,仅表现出0～20cm土壤有效P显著高于对照(CK);增施有机肥量为11000kg/hm2时,不论增施1年还是2年,玉米株高在苗期、拔节期和抽雄期均显著高于对照(CK),且玉米产量和秸秆产量也表现出最高;增施有机肥量为11000kg/hm2时,连续2年的累计经济效益最优。 |

| Abstract: | In this study, mixing pushing reclamation soil as the research object. Results showed that ： （ 1 ）Application of organic manure fertilizer volume 18 500 and 11 000 kg/hm2, regardless of one or two years of increasing, showing only at the 0 - 20 cm soil available P was significantly higher than the control （CK）; （2） Application of organic manure fertilizer volume 11 000 kg/hm2, regardless of one or two years of increasing and corn plant height at the seedling stage, jointing stage and tassehng stage were significantly higher than the control （CK）; and the corn yield and straw production also demonstrated the highest; （3）Application of organic fertilizer volume 11 000 kg/hm2 in two successive years, the cumulative economic benefits was the optimum. |
