Abstract:
Leaf lettuce seedlings of Lactuca sativa L.was used as test materials,through the way of hydroponic,using different concentrations of photosynthetic bacteria(200 mL photosynthetic bacteria bacterium agent + 3 800 mL nutrient solution,400 mL nutrient photosynthetic bacteria bacterium agent + 3 600 mL nutrient solution,600 mL nutrient photosynthetic bacteria bacterium agent + 3 400 mL nutrient solution,800 mL nutrient photosynthetic bacteria bacterium agent + 3 200 mL nutrient solution,1 000 mL nutrient photosynthetic bacteria bacterium agent + 3 000 mL nutrient solution),taking 4 000 mL nutrient solution as contral.Number of lettuce leaves,fresh mass and root vigor,vitamin C,soluble sugar,soluble protein,nitrate content were analyzed,effects different concentrations of photosynthetic bacteria on yield and quality in hydroponic lettuces were studied.The results showed that the processing effect of 600 mL photosynthetic bacteria bacterium agent + 3 400 mL nutrient solution was the best,compared with CK,leaf number increased by 62.66%,fresh quality increased by 139.7%,and root activity increased by 132.04%,vitamin C content increased by 18.34%,soluble protein content increased by 16.60%,soluble sugar content increased by 192.37%,and nitrate content decreased by 69.44%.The treatment of 600 mL photosynthetic bacteria bacterium agent + 3 400 mL nutrient ensured the hydroponic production of leaf lettuce and reduced the nitrate content,at the same time it could improve the quality of the leaf lettuce.
