【摘要】 以"美国大速"生菜为试材,研究比较了3种克孜勒苏柯尔克孜自治州(以下简称克州)现有的有机肥不同用量对其产量和品质的影响。结果表明:施用发酵羊粪有机肥和造粒鸡粪有机肥能够使生菜产量提高70.2%~118.5%,;发酵秸秆有机肥为32.0g/L时,可使产量减半。3种有机肥各处理对生菜品质效应的差异较大,施用发酵羊粪有机肥和造粒鸡粪有机肥能够明显提高生菜的叶绿素、可溶性糖含量及维生素C含量,但施用发酵秸秆有机肥及过量施用发酵羊粪和造粒鸡粪有机肥,会增加生菜体内硝酸盐含量,降低其食品安全性能。更多还原

【Abstract】 Taking lettuce‘U.S.Large-speed’as materials,effect of three kinds of existing organic fertilizers on the yield and quality of lettuce in Kirgiz Autonomous Prefecture(short as the Ke State)were studied.The results showed that application of organic fertilizer and manure fermentation of sheep manure organic fertilizer granulation could increase lettuce production by 70.2%~118.5%.Straw fermentation of organic fertilizer in 32.0g/L could make the production halved.Effects of different corganic fertilizer on lettuce quality varied a lot,the application of organic fertilizer and sheep manure fermented chicken manure granulator could significantly improve lettuce chlorophyll,soluble sugar and Vitamin C content,but the application of organic manure and straw fermentation excessive application fermented sheep and granulated chicken manure,would increase the nitrate content in lettuce,reduce its food safety performance.更多还原
