秸秆生物反应堆技术及其在污染防治中的研究——以天津市宁河县设施农业为例

选取天津市宁河县设施农业黄瓜为示范工程,采用秸秆生物反应堆技术进行种植,同时取附近普通对照区用传统方法种植做对比试验。结果表明,示范区在CO2效应与热量效应、土壤改良、作物生长及品质改善等方面均优于对照区。经济效益、环境效益分析得出,示范区的化肥施用量节约50%以上,产量增加45%,经济收益提高39%。同时,削减农田径流面源污染负荷TN 1.07 kg/hm2、TP0.11 kg/hm2,综合效益明显优于对照区。

Application of Straw Bioreactor Technique in Pollution Control

With Ninghe County of Tianjin as the demonstration area,the cucumber planted in the greenhouse with straw bioreactor technique in this area was compared with that planted by traditional method in nearby greenhouse(control).As indicated by the result,the demonstration area was better than the control area in its CO2,heat energy,soil improvement,crop growth and quality improvement and so on.As shown by the analysis of the economic and environmental benefits,in the demonstration area,the fertilizer consumption decreased by more than 50%,while the yield increased by 45%,economic yield improved by 39%.What's more,the non-point pollution load of farmland runoff TN and TP were cut off by 1.07 kg/hm2 and 0.11 kg/hm2 respectively,the comprehensive benefits of the demonstration greenhouse was obviously higher than that of the control area.
