摘　　要：通过3项田间定位试验研究表明 ,蔬菜生产中采用N、P、K平衡施肥 ,增施优质微生物肥料 ,微生物肥料与无机化肥、有机肥料配合等施肥技术 ,提高了蔬菜的产量、产值 ,增产幅度在10.05 %～16.90 %,蔬菜体内的硝酸盐含量降低了25.4～702.0mg/kg。Three tests with a field positioning method were done in vegetable for reduction of nitrate contamination. It has been indicated that the agricultural products with both quantity and profits had increased by a range of 10.05%～16.9%, while nitrate contents were reduced by a range of 25.4-702 mg/kg through appropriate application of fertilizers such as balanced fertilization of N, P, and K, adding good-quality of microorganism's nutrients, combination of fertilizers and organic manure etc.
