Tea residue wormcast substrate suitable for leafy vegetable seedling and manufacturing method thereof

Abstract

The invention discloses a tea residue wormcast substrate suitable for leafy vegetable seedling and a manufacturing method thereof. The substrate comprises, by volume, 20-40% of tea residue wormcast, 10-30% of perlite, 10-30% of vermiculite and 20-40% of peat. The tea residue wormcast is wormcast generated in the mode that earthworms digest tea residues and cow dung serving as an earthworm cultivation substrate. A traditional single mode that the earthworms are cultured through pure cow dung is broken through, earthworm composting reasonably combining the cow dung and the tea residues is achieved, the nutrition content of the wormcast is improved, and the role of the peat in a traditional soilless culture technology is weakened to a large extent when the wormcast serves as a leafy vegetable seedling substrate. The compound method of the leafy vegetable seedling substrate is optimized, quality of leafy vegetable seedling is improved, economic benefits are improved, and a way for recycling the tea residues is developed at the same time. A new method for breeding the earthworms through the tea residues is developed, and ways for earthworm culture and wormcast production are increased.

Description

technical field [0001] The invention belongs to the field of biological treatment of agricultural solid waste and resource utilization, and in particular relates to a tea dregs vermicompost matrix suitable for leaf vegetable seedling cultivation and a preparation method thereof. Background technique [0002] Leafy vegetables use the fat and tender leaves and petioles of plants as edible parts. Studies have shown that different seedling substrates significantly affect the growth and development of leafy vegetable seedlings. Therefore, screening suitable raw materials is used to prepare leafy vegetable seedling substrates , is one of the research topics of horticultural workers. [0003] With the rapid advancement of agricultural intensive production, more and more agricultural waste, especially livestock and poultry manure, has caused a large accumulation of agricultural waste, which in turn has caused serious environmental problems and waste of resources. As the largest tea...
