Abstract

Abstract:

In order to explore the resource utilization of kitchen waste products, a comparative experiment was conducted on the effect of nutrient soil prepared from kitchen waste products and biogas residue on the quality of watermelon seedlings. The difference between nutrient soil and commercial substrate in watermelon seedling cultivation was analyzed, providing theoretical and technical support for the kitchen waste products in watermelon seedling cultivation. The results showed that the nutrient soil substrate treatment (T3) had no significant impact on the quality of watermelon seedling cultivation. The Shouchuang nutrient soil substrate and Kangcheng brand substrate mixed in a 1∶1 ratio (T2) had a watermelon seedling emergence rate of 98%. The botanical and physiological indicators of watermelon seedlings substrate treatment (T2) were better than those of commercial seedling substrate treatment (T1), which met the requirements of seedling growth and had advantages in terms of usage cost. Therefore, nutrient soil can be selected as the optimal substrate for watermelon seedling cultivation, kitchen waste can replace some of the main materials in the substrate.

Key words: kitchen waste, biogas residue, nutrient soil, watermelon, seedling
