松嫩平原农牧结合优化模式的综合研究

Optimized Pattern of agriculture-animal husbandry combination in Songnen Plain of Northeast China

利用实验生态学方法并与单一粮食种植模式相对照，研究了粮粮型农牧结合模 式和粮草间种型农牧结合模式的生产力及其养分循环平衡特征、水分利用效率和能量特 征，从而提出了黑土区发展持续农业应采用的模式及应用前景．

Using the methodology of experimental ecology and with a currently adopted pattern of mono- culture as a check. the properties of productivity, nutrient cycling and balance, water use efficiency and energy in foe patterns of grain-grain-animal husbandry and grain-grass-anmal husbandry were studied. Models for sustainable development of agriculture in black soil regions were put forward, and their application prospects were discussed.
