Novel indoor soilless culture substrate

Abstract

The invention relates to a novel indoor soilless culture substrate. The novel indoor soilless culture substrate is characterized by being prepared from the following raw materials in percentage by weight: 20-45 percent of ceramsite, 30-55 percent of perlite and 10-25 percent of cut-flower mud. The novel indoor soilless culture substrate has the beneficial effects that the substrate is high in air permeability and high in stability, is not hardened and not agglomerated after being used, is light in weight, clean and sanitary, and is soilless and has an inorganic fertilizer fundamentally; various harmful substances and disease and pest damage in a plant pot caused by soil-based flower plantation are thoroughly eliminated; compared with the growth speed of flowers and plants in soil, the growth speed of flowers and plants in the substrate is increased by 1.5-2 times; the ceramsite of the substrate is brown, the perlite is white, the cut-flower mud is green, the colors are natural and do not fade, and the raw materials are low in price.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a new indoor soilless cultivation substrate. Background technique [0002] Soilless cultivation is a technology that uses light materials such as peat or forest leaf humus and vermiculite as seedling substrates to fix plants, allowing plant roots to directly contact the nutrient solution, thereby raising seedlings. There are many existing soilless cultivation substrates, such as garden leaves, dead branches, straw, sawdust, bark, wood shavings and other industrial and agricultural wastes and leftovers. Just the right size and ready to use. However, the substrates in the prior art have various defects. For example, rock wool is easy to harden, which is not good for the roots of plants; various industrial and agricultural wastes such as fallen leaves, dead branches, straw, sawdust, bark, and shavings in the garden may lead to the breeding of various harmful substances and p...
