Abstract

The invention discloses a compound tobacco seedling raising substrate. The substrate is prepared by compounding manioc waste, coconut chaff silks and a grass carbon organic material which are subjected to fermented composting processing as well as vermiculite and a pearlstone inorganic material, and is characterized by comprising the following components in parts by weight: 2-4 parts of fermented manioc waste, 1-3 parts of coconut chaff silks, 1-2 parts of grass carbon, 0.5-1.5 parts of vermiculite and 0.5-1.5 parts of pearlstone. In the substrate, the substrate moisture content is 35-45%, the total porosity is 65-75%, the organic matter content is greater than or equal to 15%, the bulk density is 0.3-0.5 g/cm<3>, the total nutrient content is 1.5-2.0%, the EC value is greater than or equal to 1000 uS/cm, the pH is 5.0-7.0, and particles with the size of 1-5 mm accounts for 50% or above, wherein particles with size below 1 mm accounts for 40% or below, and particles with size above 4 mm accounts for 20% or below. The compound tobacco seedling raising substrate takes organic wastes such as manioc waste as main raw materials, and adopts effective microbial fermentation, so that the effect is particularly good, and the substrate is very suitable for tobacco seedling raising, can promote the vigorous growth of seedlings, and can be popularized and applied nationally.

Description

technical field [0001] The invention relates to a tobacco substrate, in particular to a composite substrate for growing tobacco seedlings, and belongs to the technical field of agricultural substrate applications. Background technique [0002] Tobacco is the leaf of the Solanaceae plant tobacco. The cultivation and planting of tobacco is not only used as flue-cured tobacco and cigarettes, but also has great medicinal value. "Materia Materia Medica": "It is used to treat the exterior, good at expelling all yin evils and cold poisons, miasma, rheumatism and pathogens closing the interstitial muscles, and pain in muscles and bones; used to treat the interior, good at strengthening stomach qi, dispelling turbidity and cold stagnation, and eliminating swelling and stagnation." Eating, stopping vomiting and cholera, removing accumulated insects, relieving stagnation, relieving pain, moving qi and stopping blood stasis, lifting and sinking, and reaching the triple burner." Smoking...
