不同配比蔬菜渣青贮可行性研究

为了探讨农业生产废弃物蔬菜渣青贮的可行性,在裹包青贮条件下,添加不同比例的玉米芯和小麦秸秆调节水分,结果表明随着小麦秸秆和玉米芯添加比例升高,粗蛋白、粗灰分、粗脂肪、钙、磷含量呈下降趋势,干物质、粗纤维、中性洗涤纤维的含量逐渐升高。综合考虑蔬菜渣青贮饲料的感官指标和营养价值,宜选择玉米芯、小麦秸秆、蔬菜渣(1:1:8)进行青贮发酵。

A Mew Technique to Rapidly Test Agrochemicai Residues In Fruits and Vegetables

Extraction of AchE, relationship between substrate and enzyme concentration, and inhibition effects of the agrochemicals to AchE are discussed in this paper. Through the re-search, the proper AchE concentration for hydrolysis of 1 ml 1mmol/L substrate and I50 val-ues of the agrochemicals to AchE are decided. It is proved that Asch-DTNB method is a rapid test tool for agrochemical residues in fruits and vegetables.A rapid test card has been developed with sensitivity of 0.05mg/L.
