Abstract

The invention provides a method for preparing a tomato soilless culture substrate. Corn straw is obtained, air-dried and smashed, obtained straw particles are placed in a preprocessing solution to be cooked and filtered, then the preprocessed particles are added into a phosphate buffering solution containing compound enzyme to be subjected to extraction, enzyme deactivation and filtering, finally the enzymolyzed particles are mixed with chicken manure, diammonium hydrogen phosphate, magnesium sulfate, manganese sulfate, chitosan, nicotinamide, gypsum and water are added after high-speed diffusion, high-temperature static composting and airing are conducted, and the substrate is obtained, wherein the preprocessing solution is an aqueous solution of calcium hypochlorite, sodium bicarbonate, urea, sodium chloride, disodium 5'-ribonucleotide, potassium sorbate, pregelatinized starch, calcium nitrate terahydrate and formic acid. By means of the culture substrate prepared through the method, tomato seedlings grow strongly, plant height, stem thickness, leaf number, seedling index and other indexes are obviously better than those of seedlings cultured with turf, and the yield of single tomato plants and quality of obtained fruits are obviously higher than those of tomatoes cultured with turf.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a preparation method of a tomato soilless cultivation substrate. Background technique [0002] Soilless cultivation substrate refers to a growth medium used when cultivating plants using soilless cultivation technology. This medium can provide stable and coordinated water, air and fertilizer for plant growth, and has the function of fixing and supporting plants. [0003] At present, a large number of vermiculite and peat are used as substrates at home and abroad, because peat has ideal physical and chemical properties, but the large-scale development of peat seriously threatens and destroys ecological resources. The destruction of this resource has received widespread attention in the world. At the same time, due to the limited resources of peat charcoal, the price continues to rise, resulting in higher costs for seedling raising and cultivation. Therefo...
