[0001] The present invention relates to the technical field of plant cultivation, and in particular to an adjustable culture rack for symbiotic control experiments of leguminous plant rhizobia. Background Art

[0002] Leguminous plants are a common type of cultivated crop in life. In order to ensure the survival rate and yield of leguminous plants during cultivation, it is necessary to continuously simulate the growth environment for cultivating leguminous plants. When conducting the cultivation work of leguminous plants, different data need to be taken for control experiments in order to adjust the cultivation environment of leguminous plants, so as to cultivate high-quality leguminous plants more scientifically and efficiently;

[0003] However, when the general leguminous plant culture rack is carrying out the cultivation work, the growth environment inside it is limited. Different leguminous plants have different growth heights. When conducting the cultivation work, if the internal growth space is insufficient, it will lead to the growth of leguminous plants being restricted, resulting in inaccurate data recording. Moreover, the general leguminous plant culture rack only mimics the cultivation conditions under different temperature conditions, and the data it can collect is limited.
