Abstract:
Abstract:Chemical fertilizers often affect the vegetable quality and do harm to the soil.In order to settle this problem，the research of the effect of P.indica on lactuca ，s yield and quality were studied，this study could provide theoretical basis for high-yield cultivation of lactuca and development of new bacterial fertilizer.Taking P.indica as material,and taking Lactuca satira as reasearch object,no fertilizer treatment as control (CK)，and application of P.indica at seedling stage.The results showed that the P.indica had significant influence on yield of lactuca.Plant height was increased by 13.7%，stem thickness was increased by 12.5%，root fresh weight was increased by 15.1%，stem fresh weight was increased by 53.2%，and leaf fresh weight was increased by 61.9% compared with CK.The results also showed that P.indica not only could promote yield，but also could increased quality.The content of proton was increased by 83.33% and 12.25% in stem and leaf respectively.In addition，the content of soluble sugar was increased by 27.53% and 15.24% in stem and leaf respectively.The vitamin C content was increased by 59.5% and 73.6% compared with CK in stem and leaf respectively.All above results showed that P.indica had a very marked effect on yield and quality of lactuca.It was the best to fertilize in seedling stage.
