Abstract:
Taking ‘Longtian 1’ melon as the test material，seedling pots and greenhouse borders were used，the effects of different concentrations of Trichoderma asperellum agents (1.0×104,5.0×104,2.5×105,1.25×106 cfu·g-1） on morphological and physiological indicators，as well as indicators of melon quality and yield formation in melon seedlings were studied，in order to provide reference for melon production.The results showed that different application rates of T.asperellum agents were effective in increasing seedling plant height steam diameter root shoot ratio and strong seeding index，among them，2.5×105 cfu·g-1 of T.asperellum agents treatment had the best effect on the promotion of melon seedling morphogenesis.At the same time，different application rates of T.asperellum agents improve physiological characteristics of melon seedlings，improvement of fruit quality and yield，T.asperellum agents treatment at a concentration of 2.5×105 cfu·g-1 had the most significant effect on the physiological indexes，25 days after melon seedling emergence，root activity total absorption area of seedlings and chlorophyll content，NR activity，soluble sugar content and soluble protein content of leaves were increased by 14.81%,15.18%,21.45%,40.56%,60.05%,75.17% over CK，its fruit soluble sugar content，soluble protein content，vitamin C content，single melon weight and yield increased by 9.45%，54.02%，111.91%，12.34%，46.81%，respectively，compared with CK，respectively.In conclusion，T.asperellum agents by improving physiological characteristics of melon seedlings，promote seedling morphogenesis，this in turn improved fruit quality and yield，2.5×105 cfu·g-1 T.asperellum agents was the most effective for application，important for ensuring high yield and quality production of melons.
