Floating seedling substrate prepared from vinegar residues and preparation method thereof

Abstract

The invention discloses a floating seedling substrate prepared from vinegar residues and a preparation method thereof. The floating seedling substrate comprises the following components including, byweight, 70-85 parts of a vinegar residue material, 5-10 parts of perlite, 5-10 parts of vermiculite and 5-10 parts of coco coir. The fermented vinegar residue material is prepared by mixing and fermenting the vinegar residues, mushroom residues and / or rice bran and eggshell powder. The collected glutinous rice vinegar residues are spread to be aired or directly dried to be mixed with the collectedfermented mushroom residues and eggshell powder, a vinegar residue fermentation microbial inoculum is added, fermenting in a fermentation box is carried out until the vinegar residues are thoroughlydecomposed, and other materials are added to ferment again, so that the floating seedling culture substrate disclosed by the invention is obtained. The floating seedling culture substrate is light, capable of absorbing water and is good in breathability; and the vinegar residues contain a large amount of crude protein, crude fiber and rich trace elements such as iron, zinc, selenium and manganese,required nutrition can be well provided for growth of plant seedlings after the vinegar residues are thoroughly decomposed and fermented, a water bed nutrient solution is well supplemented, the seedling raising quality can be improved, and good economic and environmental values are realized.

Description

technical field [0001] The invention relates to a floating seedling raising substrate made of vinegar grains and a preparation method thereof. [0002] technical background [0003] In recent years, the way of raising vegetable seedlings in my country has been rapidly developing from traditional flat bed seedling raising and nutrient pot seedling raising to plug seedling raising, which has greatly promoted the research on the application of seedling raising substrates. Among them, floating seedling cultivation is a new seedling raising method. It is a seedling raising method in which a foam tray equipped with a light seedling-raising substrate is floated on the water surface, seeds are sown in the substrate, seedlings take root and grow in the seedling-raising substrate, and can absorb water and nutrients from the substrate and the water bed. This seedling raising method is mostly used as an agricultural planting technique for plants such as green leafy vegetables and tobacc...

Problems solved by technology

However, domestically produced peat has a high degree of decomposition, a relatively high proportion of particles with a particle size of less than 0.5mn, a small saturated water holding capacity, and a high content of total N, total P, and total K. Slow seedling emergence, poor plant uniformity, low seedling growth index and other problems; and the high quality peat imported from abroad is expensive, making the cost of seedling cultivation high

In addition to peat, light seedling substrates such as vermiculite and perlite meet the requirements of light weight for floating seedling substrates, but their water holding capacity is limited, and they are all inorganic substrates, which in turn require more water bed culture fluid.
