| 摘 要： | 系统分析了晋东丘陵旱农地区（寿阳）农作物秸秆资源及其利用现状,通过秸秆过腹还田生态系统物质循环；粪肥与秸秆配合还田、培肥土壤的定位试验；及其旱地水分利用效率等研究,获得秸秆过腹还田、农田休闲期秸秆覆盖、作物生育期秸秆覆盖和直接还田等４种利用途径的有关参数。以秸秆所产生的经济效益最大为目标函数,运用线性规划模型,优化秸秆综合利用结构,对北方旱地农作物秸秆资源综合利用具有一定的指导意义。

| Abstract: | Crop stalk resources and their current utilization conditions in dry land hilly area of Shouyang County are analyzed.Correlative parameters were taken from the studies on material cycling of animal feed stalk to crop land,site experiment of fertilizing with assorted stalk and manure,covering field with stalk as mulch in different seasons,stalk back to field directly,and crop land water utilization efficiency with different treatments of stalk.An optimization utilization structure of crop stalk was suggested by Linear Programming method for gaining the maximum stalk net profit to provide significant benefits for comprehensive utilization of crop stalk resources in dry land area. |
