Abstract

Abstract:

This study aims to explore the impact of a novel hydrogen fertilizer material on the growth of wax gourd seedlings, determine the optimal dosage of hydrogen fertilizer for wax gourd seedling cultivation, and provide a theoretical basis and data support for cultivating robust seedlings using hydrogen fertilizer. The black-skinned wax gourd ‘Tiezhu 2’ was used as experimental material. This research established five gradients of hydrogen fertilizer application and conducted experiments by incorporating the hydrogen fertilizer into the seedling substrate, to investigate its effects on the emergence rate, seedling growth, sound seedling index, root morphology and chlorophyll content in wax gourd. The application of hydrogen fertilizer exhibited a dose-dependent effect on the growth of wax gourd seedlings, with the control (no hydrogenation fertilizer) and five different dosage of hydrogen fertilizer resulting in sound seedling indexes of 1.05, 1.49, 1.52, 1.55, 1.46, and 0.99, respectively. Comprehensive analysis found that the treatment with a hydrogen fertilizer to substrate ratio of 1 kg: 3000 L (H₂) had better efficacy. Compared to the control, wax gourd seedling treated with H₂ exhibited a 17.5% increase in seedling emergence rate, a 45.6% improvement in sound seedling index, a 23.5% increase in the number of root tips, and a 25.8% increase in the chlorophyll a content. Excessive application of hydrogen fertilizer (hydrogen fertilizer: substrate> 1 kg: 1000 L) did not significantly affect the emergence rate of wax gourd but inhibited the growth of seedlings and reduced sound seedling index. Hydrogen fertilizer improves the emergence rate and uniformity of wax gourd, stimulates seedlings growth, and is beneficial for cultivating robust seedlings. However, it is important to note the application dosage. The optimal hydrogen fertilizer-to-substrate is 1 kg: 3000 L, as excessive dosages can produce adverse effects.

Key words: hydrogen fertilizer, wax gourd, seedlings cultivation, emergence rate, root morphology, sound seedling index, chlorophyll
