摘要
为了明确智能控氧微生物发酵技术生产的生物腐植酸有机肥对衢州地区土壤的改良及蔬菜产量提高的效果,以青菜品种衢州青为试材,以当地有机肥为对照,生物腐植酸有机肥按照30%当地有机肥和75%复合肥施肥量进行试验。结果显示,青菜的土壤有机质和全氮含量较施肥前平均分别增加13.7%和3.2%,与对照相比,667 m2产量平均增加7.9%,肥料投入减少378元,纯收益平均增加911元。
In order to investigate effects of biological humic acid organic fertilizer producing by technology of biological fermentation on soil improvement and pakchoi yield increase in Quzhou, we took local pakchoi cultivar Quzhouqing as experiment material and local organic fertilization as control, and set 30% local organic fertilization application amount and 75%compound fertilizer application amount as the base fertilizer of biological humic acid organic fertilizer treatment. The results showed that soil organic matter and nitrogen contents increased by 13.7% and 3.2% after the fertilizer application. Moreover, compared to control, the yield increased by 7.9%, with fertilizer input decreased by 378 Yuan/667 m2, and net income increased by 911 Yuan/667 m2.
