Plug seedling substrate of tomatoes and preparation method

Abstract

The invention discloses a plug seedling substrate of tomatoes and a preparation method. Peat is taken as the material; excrements of livestocks are taken as earthworm foodstuff; environment suitable for the growth of earthworms is provided; wormcast which is processed and generated by the earthworms is sieved to obtain wormcast compost with the grain size being 1-4mm; and the peat and the wormcast compost are fully mixed; mineral materials with a certain fineness such as expandable vermiculite, perlite and the like are added to improve the physical properties and the buffer performance of the substrate to generate a novel tomato seedling substrate. The percent by volume of various components are that the peat accounts for 15-25%, the wormcast compost accounts for 55-65%, the expandable gardening vermiculite accounts for 5-15% and the perlite accounts for 5-15%. The plug seedling substrate disclosed by the invention has the advantages of simplicity in preparation method, richness in resource, low cost of materials, turning waste into wealth, reducing environmental pollution and sufficient nutrient. The plug seedling substrate is used for the plug seedling of tomatoes, eliminates top application during seedling raising, improves the quality of tomato seedlings and reduces the pesticide application. Thus, the seedling quality is ensured, the cost and the labor are saved and the survival and the high-quality and efficient growth of the tomato seedlings, the yield and the construction of quality are ensured.

Description

technical field [0001] The invention relates to a tomato plug seedling raising substrate and a preparation method, belonging to the technical field of substrate seedling raising. Background technique [0002] Substrate seedling cultivation refers to a method of crop seedling cultivation that provides a place for crop seed germination and seedling growth through a substrate in a certain place or container, fixes the root system of the crop and allows it to absorb nutrients and oxygen. According to the development trend of seedling raising methods, matrix seedling raising will become the mainstream seedling raising method. Seedling substrate refers to the growth medium that can provide water, fertilizer, air, heat and other life factors for the stable and coordinated supply of crop seed germination and seedling growth. In addition to supporting and fixing seeds and seedlings, it is more important to act as a carrier of nutrients and water. The nutrition from itself and the nu...
