摘要： 在一块肥力较低的土壤中，开展辣椒施用光合菌剂的大田实验，研究光合菌剂对辣椒生长发育及土壤微生物活性的影响。结果表明，肥力水平是影响辣椒生长发育的重要因素，施用光合菌剂能明显提高盛果期叶片中氮含量，获得单果重更高、果实更饱满，收获期辣椒植株的长势最好；在整个生育期内，光合菌剂处理的土壤微生物活性最高。因此，在贫瘠的土壤中，在补充肥力的基础上，光合菌剂能一定程度上改善土壤微生态环境，促进辣椒植株生长和果实发育，具有良好的应用前景。

Abstract: A pepper field experiment was conducted for applying photosynthetic bacteria in relatively poor-fertility soil to study the effects on pepper growth and soil microbial activity. The results showed that fertility level was an important factor affecting the pepper growth, the photosynthetic bacteria could significantly improve nitrogen content in leaves to get heavier and fuller fruits，and plants with best growth at harveat timeof. During the whole growth period，soil treated by photosynthetic bacteria kept the highest soil microbial activity. Thus, on the basis of the fertility supplement, photosynthetic bacteria can improve soil microenvironment of poor soil，promote pepper plant growth and fruit development，showing considerable application prospects.
Key words: photosynthetic bacterium, growth and development, basis-respiration
