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。
In a low-fertility soil, field trials of photosynthetic bacteria in pepper were carried out to study the effects of photosynthetic bacteria on pepper growth and soil microbial activity. The results showed that the level of fertility was an important factor affecting the growth and development of pepper. The application of photosynthetic bacteria could significantly increase the nitrogen content in the full-fruit stage, with higher single fruit weight and more full fruit. The growth of pepper plants was the best during the whole period. During the growth period, photosynthetic bacteria treatment of soil microbial activity of the highest. Therefore, in poor soil, on the basis of fertilization, photosynthetic bacteria can improve soil micro-ecological environment to some extent and promote the growth of pepper plants and fruit development, and has good application prospects.
