摘　　要：每吨甘蔗渣同时加入NH4NO35.0kg、膨化鸡粪50.0kg、堆肥速效菌曲1.5kg堆沤处理后,作为无土栽培黄瓜、番茄和菜薹的基质,产量分别比CK提高12.8%、18.0%、16.4%;NO3-含量分别比CK降低43.4%、59.8%、57.5%。黄瓜和番茄的NO3-含量达到国际标准,菜薹的NO3-含量达到国家标准的要求,其它有害元素的含量也均达到无公害蔬菜产品的质量要求。Ammonium nitrate 50kg,expansion chicken manure 500kg,active compost yeast 15 kg were added into bagasse per ton to composting as matrix culturing of cucumber,tomato and flowering chinese cabbage.In contrast to control,the yield was enhanced 128%,180%,164%, respetively;the content of nitrate nitrogen was fell 434%,598%,575%,respectively.The nitrate nitrogen content of cucumber and tomato met the international standard,and that of flowering chinese cabbage met the national standard And the other harmful elements contents also met the required quality of harmless vegetables.
