Abstract

The invention discloses a special seedling-raising medium for leaf vegetables, belonging to the technical field of soilless culture. The medium comprises vinegar residue, manioc waste and other organic wastes, as well as vermiculite, grass carbon, plant ash and perlite. The formula of the medium comprises the following components in volume ratio: 25-35 parts of vinegar residue, 5-10 parts of manioc waste, 10-15 parts of plant ash, 15-20 parts of vermiculite, 20-25 parts of grass carbon and 5-10 parts of perlite; and the medium has total nutrient content of 1-3%, free water content of 25-40%, total porosity of 65-85%, volume weight of 0.1-0.8g / m<3>, pH of 5.5-7.5, EC (electrical conductivity) value of 0.5-2.0mS / cm and dry base organic matter content of not less than 25%. The special seedling-raising medium disclosed by the invention mainly takes the vinegar residue, the manioc waste and other organic wastes as raw materials, and high-temperature fermentation treatment is performed for producing the soilless culture medium, so that the wastes are changed into valuables and harmful things are further turned to beneficial things. The special seedling-raising medium has the advantages of low cost, light texture and complete nutrition, is very suitable for raising seedlings of the leaf vegetables, and becomes a good seedling-raising medium for soilless culture of horticultural crops.

Description

technical field [0001] The invention relates to a soilless cultivation seedling substrate for crops, in particular to a special seedling cultivation substrate for leafy vegetables, belonging to the technical field of soilless cultivation Background technique [0002] Soilless cultivation refers to the method of cultivating crops with substrates instead of natural soil. It is mainly used in the cultivation of fruits, vegetables or flower seedlings. It is a high-yield, high-quality advanced technology that saves water, fertilizer and labor. [0003] Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an organic or inorganic substrate, and supplies the crop nutrient solution through drip irrigation or trickle irrigation. At present, most countries in the world use gravel, sand, mud (grass) charcoal, vermiculite, perlite, rock wool, sawdust, etc. as fixed substrates. [0004] With the promotion and ...
