- Abstract
In order to explore the effects of different Trichoderma harzianum concentrations on plant growth, fruit quality, and yield of netted melon, screen the optimum concentration of T. harzianum for netted melon in agricultural production, in this study, during the netted melon planting process, concentrations of 0.15 g/m² and 0.30 g/m² of T. harzianum were applied once on the day of planting and within 7 days after pollination, with the number of viable fungi equivalent to 90 million/m² and 180 million/m². The effects of T. harzianum concentration on various aspects of netted melon were analyzed and compared by measuring the field growth of netted melon plants, including leaf area, stem diameter, plant height, root growth(root diameter, root length, root fresh weight, and root dry weight), fruit quality indicators(single melon weight, fruit vertical diameter, fruit transverse diameter, pulp thickness, edge soluble solid content, and center soluble solid content), as well as yield and commodity rate. The results indicated that the application of T. harzianum significantly increased plant height, single melon weight, fruit vertical diameter, root fresh weight, and root dry weight of netted melon, leading to increased yield and commodity rate. The experiment demonstrated that T. harzianum had a positive effect on the growth of netted melon plants and roots, as well as on the quality and yield of netted melon. Specifically, the application of 0.15 g/m² of T. harzianum had a more favorable effect on the growth, fruit quality, yield, and commodity rate of netted melon plants, while the application of 0.30 g/m² of T. harzianum had a better effect on the growth of netted melon roots. Considering economic cost factors, the application of 0.15 g/m² concentration of T. harzianum in netted melon production was more economical, requiring less T. harzianum, aligning with China's current green agriculture requirements, and being more suitable for promotion.
