【摘要】 三峡库区农业面临化肥过量施用引起的生态问题和农民增产增收的双重压力。本文选取榨菜、脐橙、蜜桔和茶叶4种典型库区农作物进行纳米碳增效生物有机肥减肥增产大田示范试验。以常规施肥量的生物有机肥为对照,纳米碳增效生物有机肥分别采用常规施肥量的100%、90%、70%和50%,研究和分析对作物生物性状和产量的影响。结果表明,该纳米碳增效生物有机肥的减肥增产效果显著。在采用常规施肥量70%的情况下,榨菜、脐橙、蜜桔和茶叶分别增产67.4%、44.4%、9.1%和23.5%。该纳米碳增效生物有机肥的施用和推广对减少因肥料流失引起的水库面源污染和增加种植经济效益潜力巨大。更多还原

【Abstract】 Four typical crops (mustard,navel orange,mandarin orange and tea) were selected for field experiment with a novel nano-carbon synergistic bio-organic fertilizer in Three Gorges Reservoir Region,which is under the double pressures of ecological concerns caused by over use of chemical fertilizers and increasing demand on rural incomes.Biological characteristics and yields were investigated with the nano-carbon synergistic bio-organic fertilizer at 100%,90%,70% and 50% of normal amount used,compared with the normal use of bio-organic fertilizer.The results showed that under the 70% normal use of the fertilizer,the mass yields of four crops increased by 67.4%,44.4%,9.1% and 23.5%,respectively,indicating this novel fertilizer has a great potential for reducing non-point source pollution caused by over use of fertilizer and its run off and to increase rural income in crop farming in Three Gorges Reservoir Region.更多还原
