试验在比较处理之间应用唯一差异原则进行设计,以探讨明确微生物菌剂的作用。结果表明,喷施微生物菌剂小白菜幼苗生长势强,株高、叶宽、单株重均显著增加,可促进增产;小白菜苗期遇到气候干旱喷施水分可补充蒸腾作用散失的水分,增强光合作用等生理过程,有明显的增产效果;选用春小白菜适时早播,延长幼苗生长期,适时适量喷施微生物菌剂,可进一步提高增产潜力和效益。
The experiment was designed using the only difference principle between comparative treatments in order to clarify the role of microbial inoculants. The results showed that the seedlings of cabbage sprayed with microbial inoculant had strong growth potential, plant height, leaf width and weight per plant all increased significantly, which could promote the yield increase. When the cabbage seedlings were exposed to the climate drought, water could be added to compensate for the loss of transpiration , Enhance photosynthesis and other physiological processes, there is a clear yield increase; selection of spring cabbage sowing at the right time to extend the seedling growth period, the appropriate amount of spraying microbial agents, can further increase the yield potential and efficiency.
