| 摘 要： | 典型黑土农田试验表明，只使用化肥不但肥料利用有效性低，而且导致土壤量大量损失，化肥和绿肥、秸秆共同使用既使得能量消耗效应有着3－5倍的本质性提高，又减少或避免了腐殖质能量损失，化肥和厩肥结合使用情况下，依靠粉碎秸秆还田也可以显著地提高能量消耗效应。

| Abstract: | The field experiment of model blackland demonstrates that nothing but fertilizer used in farm field makes the poor validity of fertilizer utilization and result in the loss of a great deal of soil energy. The combining use of fertilizer, green manure and straw can essentially improve the validity of energy consumption and make it heighten 3~5 times, furthermore, reducing or avoiding the energy loss of humus. If the use of fertilizer is incorporated with stable manure, it can remarkably improve the validity of energy consumption relying on shattered culm returned to field. |
