光合细菌对水培蔬菜硝酸盐含量的影响

The Influence of PSB (Photosynthetic Bacteria) on the Nitrate Content of the Water-cultured Vegetables

结合当地水质的特点进行了水培蔬菜试验,主要研究了在水培蔬菜中加入不同用量的光合细菌菌剂,并测定了蔬菜产量和硝酸盐含量,对结果进行了相关分析,从而找出了在不影响蔬菜产量的情况下能够有效降低生菜油菜硝酸盐含量的方法。

Connecting with the features of the local water quality, this paper makes the test on water-cultured vegetables, researches mainly on adding different amounts of microbial inoculum of PSB into the water-cultured vegetables and measures the yield of the vegetables and the contents of the nitrate, and makes correlation analysis on the results, and finds the methods for reducing effectively the nitrate contents in the lettuce and rape under the condition of no influence on the yield of the vegetables.
