Tomato seedling medium and preparation method thereof

Abstract

The invention relates to the technical field of seedling mediums, and relates to a tomato seedling medium prepared by using paper mud, mushroom residues and sand. The tomato seedling medium is composed by the following raw materials by volume: 20-30% of fermented paper mud, 20-30% of fermented mushroom residues and 40-60% of the sand. The compound medium provided by the invention can improve physical and chemical properties of the tomato seedling medium, reduces adverse effects of a single medium, cultivates the optimal tomato seedlings, promotes the growth of the tomato, can reduce production cost under the premise of guaranteeing the quality of the tomato seedling goods, realizes resource utilization of the paper mud, and has obvious social benefits, economic benefits and environmental and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of seedling-raising substrates, in particular to a tomato seedling-raising substrate prepared from paper mud, mushroom dregs and sand. Background technique [0002] tomato( Solanum lycopersicum ) is an herbaceous plant of the genus Solanaceae, including finite growth types, semi-finite growth types and infinity growth types. Can grow for many years under favorable conditions. It has a variety of varieties and a long growth period, and is loved by people. It has become one of the main vegetable crops in greenhouses and one of the main cultivated crops in winter and spring. [0003] Paper slime is the terminal product of wastewater treatment in the papermaking process. For every 1 ton of recycled paper produced, more than 1200kg of paper slime will be produced. Due to the high water content (above 60%), these papermaking waste residues and sludge are in the state of silt, with complex components and difficu...

The Chinese patent application that application number is 200810181391.6 has described a kind of seedling raising substrate and preparation method that take mushroom dregs as raw material, and it mainly mixes processed mushroom dregs, vermiculite, perlite, starter in a certain proportion to make seedling raising substrate, Although this method uses mushroom dregs instead of peat, the raw materials of organic components are single, and the decomposing period is long. Traditional matrix formulas such as vermiculite and perlite are also used, which is inconvenient to obtain materials and high in cost.

The Chinese patent application whose application number is 201010293350.3 describes a biological seedling substrate processed by papermaking sludge, which mixes processed paper mud, perlite, vermiculite, and functional bacteria to make a seedling substrate. Although this method has effectively developed paper Mud replaces peat, but the decomposing period of paper mud is long, and this method uses traditional perlite and vermiculite, which is inconvenient to obtain materials and high in cost, which affects the wide promotion of substrates
