Cucumber growing medium using pig manures and biogas residues as fertilizer sources, and preparation method of cucumber growing medium

Abstract

The invention relates to a preparation method of a cucumber growing medium using pig manures and biogas residues as fertilizer sources. The cucumber growing medium comprises biogas residues, vermiculite, turf and perlite in the weight part ratio of (2.5-3.5):3:(2.5-3.5):1. The biogas residues are from the biogas residues obtained after full fermentation in a large biogas digester, dried after solid-liquid separation and then crushed with a crusher; and Bacillus subtilis metabolites are absorbed on the turf. The defect that the traditional growing medium is predominant in turf is overcome, the usage of turf is reduced, the cost of the medium is reduced, and the ecological environment is protected; the pig manures and biogas residues are effectively utilized, the industry chain of biogas engineering is extended, and the environmental pollution caused by the pig manures and biogas residues is reduced; and meanwhile, the disease incidence rate of seedlings is effectively reduced, and the resistance against diseases of plants at the late growth stage is enhanced.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a method for preparing a cucumber seedling-raising substrate using pig manure and biogas residue as a fertilizer source. Background technique [0002] At present, with the formulation of the Twelfth Five-Year Plan, the construction of green vegetable bases around the capital has also been carried out with great fanfare, and the planting scale of facility vegetables is also increasing. The quality of vegetable seedlings is not only related to the health status, disease resistance, product quality and yield of vegetables in the later stage, but also affects the healthy development of the vegetable industry. Therefore, the seedling substrate is the growth condition for the growth and development of seedlings, and its reasonable choice becomes a guarantee. The premise of the healthy development of the vegetable industry. At present, there are still seedling ...
