光合细菌对不结球白菜生长发育和品质的影响

摘要

In this study, we did an experiment about photosynthetic bacteria’s effect on growth and quality of non-heading Chinese cabbage. Results showed that non-heading Chinese cabbage plants’ growth was improved by photosynthetic bacteria treatment. Compared to the control, the plant height, leaf area, yield per plant, and total chlorophyll content increased 37.35%, 45.97%, 57.06%and 66.5%, respectively. The quality of non-heading Chinese cabbage plants was also improved by photosynthetic bacteria treatment. Compared to the control, the soluble sugar and Vc content increased 39.06%and 19.73%, respectively, and nitrate content decreased 26.29%. It can be seen that photosynthetic bacteria could significantly promote the growth and quality of non-heading Chinese cabbage.%对光合细菌在促进不结球白菜生长发育和品质提升中的作用进行研究，结果表明，光合细菌处理可明显促进不结球白菜的生长发育。与对照相比，不结球白菜株高、叶面积、单株产量和叶片总叶绿素含量分别增加了37.35%、45.97%、57.06%和66.5%；提高了不结球白菜的品质，光合细菌处理的植株可溶性糖和Vc含量分别比对照提高了39.06%和19.73%，硝酸盐含量降低26.29%。可以看出光合细菌可明显促进不结球白菜的生长发育和品质的提升。
