Keywords:
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 32.0 g/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.
