Applied studies of plant meridian system: I. The effect of agri-wave technology on yield and quality of tomato.

Agri-wave technology is a new agricultural technology based on the plant meridian system, that focuses on measurement of plant sound characteristics. The basic principle of agri-wave technology is to improve the yield and quality of plants such as vegetables, flowers, and fruit trees by broadcasting sound waves of certain frequencies and spraying a compound microelement fertilizer on the leaves. The application of agri-wave technology on tomatoes remarkably stimulates growth of their seedlings. Fresh weight of the branch, stems, and leaves of the treated tomatoes is significantly (59.53%, P < 0.0001) higher than that of the control group. Sampling survey results indicate that agri-wave technology accelerates the ripeness of tomatoes. The fresh weight of ripe tomatoes treated with this technique is 30.73% higher than that of the untreated (P = 0.0018), while the fresh weight of the treated unripe tomatoes is 27.29% lower than that of the untreated unripe group (P = 0.0020). Yield surveys show that the yield of treated plants is 13.89% (p < 0.0001) higher than that of the control group. Moreover, with agri-wave technology treatment the storage period of tomatoes is almost doubled. Analysis of tomato nutrition shows that agri-wave technology has increased their sugar content by 26.19%, vitamin A and niacin (an antifavours vitamin) by 55.39% and 92.31% respectively. There is no difference concerning vitamin B1, B2, and D content between the two groups, and vitamin C and E contents decreased by 2.10% and 12.69%, respectively. Among the analyzed 33 minerals of tomatoes, 26 increased in content, while 7 decreased. In conclusion, agri-wave technology has promoted the growth of the tomato, increased its yield, and improved its quality.
