[0082]

[0083] Example 8: Comparison of rubber grass culture under different culture conditions

[0084] Three treatment groups were set up, among which: Group A was cultivated using the hydroponic rubber grass integrated system and the hydroponic rubber grass system control device provided in the present application, Group B was cultivated using the hydroponic device and conventional hydroponic method available on the market, and Group C was cultivated using the method of cultivating rubber grass in greenhouse soil. 30 individual plants were selected for each indicator for growth physiological index detection.

[0086]

[0087] As shown in Table 2, the three treatment groups all had significant differences in the six indicators of root length, stem thickness, plant width, leaf length, fresh mass of the underground part of a single plant, and fresh mass of the aboveground part of a single plant. Group A used the method of the hydroponic rubber grass integrated system and the hydroponic rubber grass system control device provided by the present application to cultivate root length, stem thickness, plant width, leaf length, fresh mass of the underground part of a single plant, and fresh mass of the aboveground part of a single plant. The indexes were all higher than those of Group B and Group C, indicating that the hydroponic rubber grass integrated system and the method of the hydroponic rubber grass system control device provided by the present application are more suitable for the cultivation of rubber grass, can better control the growth environment of rubber grass, and stimulate the growth of rubber grass. Compared with the agronomic trait indicators of group B and group C, the results of group C were better than those of group B, indicating that the rubber grass cultivated under inappropriate hydroponic conditions had lower trait indicators than the rubber grass cultivated in greenhouse soil. It can be seen that a systematic, dedicated, and specific cultivation condition hydroponic rubber grass integrated system and hydroponic rubber grass system control device have an important positive effect on the growth of rubber grass.
