  But the phenomenon of Coal spontaneous combustion is quite serious, it badly restricts safe production and development of high-productivity and high-efficiency mines, At the same time it brings huge resource waste, environment pollution, the loss of personnel and property.

  但是，煤炭自燃现象却比较严重，严重制约了高产高效矿井的安全生产与发展，造成巨大的资源浪费、环境污染、人员和财产的损失。

  The highest yield was 9 208 kg·hm-2 under 240 kg·hm-2 nitrogen fertilizer application. High yield and high efficiency treatment reduced 30%-40% nitrogenous fertilizer,but rice yield increased 5.5%,and raised the nitrogen agronomic efficiency by 67.8%-98.4%.

  结果表明:采用最佳养分管理技术,优化养分运筹,增产31%～46%,施氮量为240 kg.hm-2时可获得最高产量9 208 kg.hm-2;高产高效处理可减少肥料投入30%～40%,增产5.5%,氮肥农学效率提高67.8%～98.4%;高效处理减少48.6%氮肥用量,提高氮肥农学效率31.4%。
