| 摘 要： | 产业沼气作物是发酵制气的重要原料,开展产业沼气作物农田净生态系统生产力(net ecosystem production,NEP)和水分利用效率(water use efficiency,WUE)的研究,为产业沼气作物的筛选和种植提供依据。采用静态钠石灰吸收法和静态箱-红外CO2分析仪法、非称重式蒸渗仪法测定了常规种植条件下4种作物农田NEP和群体水分利用效率(population water use efficiency,WUEp)、生态水分利用效率(ecosystem water use efficiency,WUEe),并设裸地进行对照。结果表明:1)观测的5个处理,NEP的大小顺序是杂交狼尾草(17 533.1 kg/hm2)曲晨9号玉米(9 172.9 kg/hm2)云瑞88玉米(8 462.7 kg/hm2)紫花苜蓿(273.6 kg/hm2)裸地(-2 377.0 kg/hm2),4种作物农田是CO2的汇,裸地是源。2)WUEp大小排序为杂交狼尾草(10.89 kg/m3)曲晨9号(7.23 kg/m3)云瑞88玉米(6.79 kg/m3)紫花苜蓿(3.46 kg/m3)。WUEe大小顺序为杂交狼尾草(4.19 kg/m3)曲晨9号(2.38 kg/m3)云瑞88(2.20 kg/m3)紫花苜蓿(0.06 kg/m3),与NEP的排序相同。以生物量、NEP、WUEp、WUEe来衡量,杂交狼尾草优于其他3种作物,可优先推广种植。
