Effects of Biochar Application Rates on Growth, Development and Fruit Quality of Oriental Melon with Fennel Companion Cultivation
Journal Title: Journal of Shenyang Agricultural University - Year 2025, Vol 56, Issue 3
Abstract
[Objective]As a soil amendment, biochar has the advantages in increasing soil fertility, promoting crop growth, and enhancing crop yield. This study investigated the effects of different biochar application rates on plant growth, fruit quality, and mineral nutrient uptake of oriental melon with fennel companion cultivation in a solar greenhouse. [Methods]The treatments included the application of 10 g (BOF10), 20 g (BOF20), and 40 g (BOF40) of straw-derived biochar. The aim was to determine the optimal biochar application rate for oriental melon with fennel companion cultivation and provide a theoretical and practical basis for improving its effectiveness. [Results]The experimental results showed that under the oriental melon with fennel companion cultivation, different biochar application rates (BOF10, BOF20, and BOF40) promoted root growth to varying degrees, enhanced root activity and photosynthetic capacity, facilitated mineral nutrient uptake, and increased plant dry and fresh weight. Among them, the BOF20 treatment exhibited the most significant effects. Regarding fruit quality, both BOF20 and BOF40 treatments significantly increased the soluble solids content, vitamin C content, and single fruit weight. [Conclusion]BOF20 was identified as the optimal biochar application rate for the oriental melon with fennel companion cultivation.
