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 50kg,expansion chicken manure 500kg,active compost yeast 15 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 128%,180%,164%, respetively;the content of nitrate nitrogen was fell 434%,598%,575%,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.
