农牧复合生态系统氮磷营养循环与提高养分利用率的研究

Nitrogen and Phosphorus cycling and Nutrient Use Efficiency Improvement in Agriculture and Animal Husbandary Ecosystem

  • 摘要: 本项实验研究(1988-1991)通过田间试验、饲喂试验和农牧结合的生态农业实体运营,使农田亚系统的氮肥利用率达到56.9%,磷36.3%,整个农牧复合系统的养分回收率氮49.9%,磷37.6%,比单一种植业的利用效率提高10-20个百分点,这在太行山前平原资源节约型生态农业建设中,是一种高效益的生态农业示范模式,生产上已开始推广应用。

     

    Abstract: The results from field experiments,animal feeding experiments and comprehensive agro-husbandary entities showed that the untrient recovery rate for the whole agro-husbandary ecosystem reached 49.9% for N and 37.6% for P,in farmland subecosystem nutrient use effeciency was 56.9% for N and 36.3% for P,which were 10-20% higher than in single cropping system.It was suggested that this agro-husbandary ecoagricultural model be appropriate for development of resource-saving eco-agriculture in the plain located in front of Mountain Taihang.
