Straw filament and cow urine fermented material prepared nursery and culture substrate

Abstract

Disclosed is a straw filament and cow urine fermented material nursery and culture substrate. The straw filament and cow urine fermented material prepared nursery and culture substrate is prepared from the raw materials of, by weight percentage, 20-30% of cow urine, 8-20% of perlite or vermiculite or a mixture of perlite and vermiculite, 16-60% of straw filament and 10-20% of turf. The invention also relates to a preparation method of the straw filament and cow urine nursery and culture substrate. The method comprises rubbing straw filaments, fermenting the straw filaments and cow urine, and mixing the fermented materials with the perlite or vermiculite or the mixture of the perlite and the vermiculite as well as turf. The straw filament and cow urine fermented material nursery and culture substrate has the advantages that the rubbed straw filaments are large in specific surface area and high in absorbability to water and fertilizer and accordingly are beneficial to on-site cow urine cleaning and absorption of fermented fertilizer; application of bacteria can be reduced or even saved; rubbing treatment on straw can damage ash on the surface of the straw, so that the straw can turn easy to ferment, and the fermentation time can be shortened by more than 50%.

Description

[0001] Technical field: [0002] The invention relates to the technical field of cultivation and seedling-raising substrates, in particular to a seedling-raising and cultivation substrate produced from straw silk and cow urine fermented products. [0003] Background technique: [0004] In order to reduce the spread of diseases, intensive cattle farms are supported by the National Law Reform Commission. Therefore, in recent years, the investment has been relatively large. Intensive cattle farms, including dairy and beef cattle breeding, require a bed-bed farming model. One cow defecates every day At 20-30kg, the urination is about 10kg. Such a large amount of feces and urine is a difficult problem for every farm to deal with. Faced with the large amount of cow dung and cow urine mixture produced every day, the fluidity itself is poor, it is not easy to transport, and what’s more, there is still water If it is flushed, it will form a mixture of feces and water, which is difficult...

It is difficult to transport fresh cow dung if it is sold directly

Afterwards, people generally hoped to treat cow dung through biogas digesters, but the dung materials entering the biogas digesters have not been separated from solid and liquid. The actual use has proved that the effect of such direct biogas cultivation is not ideal; because the untreated feces and urine water Entering the biogas digester greatly increases the organic load per unit volume of the biogas digester, so the volume of the biogas digester will increase a lot

Due to the long-term use of the biogas digester, a large amount of residue is left after fermentation, which makes the biogas digester clogged and the capacity is reduced, making the biogas digester unusable, and the cleaning of the digester is labor-intensive and extremely unsafe, and at the same time increases expenses

[0006] On the other hand, because rice straw has a lot of ash (silicate) and high silicon content, it is not easy to ferment, and its nutrition is low when used as feed. In the past, it was mostly incinerated, which polluted the environment and was also a waste of rice straw.
