摘　　要：农村生物质含有大量的氮素,就地肥料化既缓解环境污染问题,又能创造经济效益。该研究以沂蒙山区典型村庄蒋家庄为例,实地调查和分析了该村生物质资源量与氮含量,并利用田间试验探讨了其生产有机主粮的潜力与经济效益。结果表明,蒋家庄植物生物质量(干基)为722.5t·a^(-1),禽畜粪尿(鲜量)2703.1t·a^(-1),可降解生活垃圾(鲜基)25.4t·a^(-1),三者折合纯氮为18.88t·a^(-1)。1kg牛粪可生产1.04kg有机主粮,1kg植物生物质有机肥平均可生产0.53kg有机主粮。该村生物质氮总量可满足全村农作物有机种植需求,经济效益可增加2倍以上。Rural biomass contains large amount of nitrogen fertilizer resources, in situ fertilization can not only alleviate environmental pollution, but also create considerable economic benefits. Taking Jiangjiazhuang Village, a typical village in Yimeng Mountains of Shandong Province, as a case, we investigated and analyzed the biomass resources and nitrogen amount of the village, and explored the potential and economic benefits of biomass resources in producing organic grains using exact field experiments. The results showed that the amount of plant biomass(dry base),livestock feces and urine(fresh base)and degradable domestic garbage(fresh base)in Jiangjiazhuang was 716.8 t·a-1, 2703.08 t·a-1, and about 25.40 t·a-1, respectively, which were totally equivalent to 18.78 t·a-1 of pure nitrogen.Biomass fertilizer can be transformed into organic grains(wheat + corn)in situ. It was noted that 1 kg manure biomass fertilizer could produce 1.04 kg organic grains, and 1 kg plant biomass fertilizer produce 0.53 kg on average.The total amount of biomass nitrogen in the village can satisfy all the crop field for organic planting, which increased the economic benefits by more than 2 times.
