The invention discloses a cucumber
seedling substrate. The cucumber
seedling substrate is prepared from, by weight, 1.5-2.5 parts of
biogas dregs, 4-6 parts of
chicken manure, 35-45 parts of biological carbon inoculant, 1.5-2.5 parts of
straw powder and 1 part of
perlite. The preparing method comprises the steps of taking components by weight part and mixing evenly the components through a roller. According to the cucumber
seedling substrate, no grass carbon is adopted at all, therefore, the problems that grass carbon is expensive and is non-renewable in resource are solved, meanwhile the problem that large
biogas residues pollute environment and an environment
pollution problem brought by random stacking and arbitrary firing of corn and wheat
straw are solved, and the cucumber seedling substrate can effectively maintain living and life environment of people, is beneficial to cycle development of
agricultural economy, and has remarkable economic and
social benefits. The use of the cucumber seedling substrate can effectively promote the growth of cucumber root systems, meanwhile is beneficial to reducing occurrence of soil-borne diseases, reduces the use of
chemical agents, and facilitates the production of green vegetables.
