Abstract

The invention discloses a lightweight matrix for sky-rise greenery and belongs to the technical field of gardening. The lightweight matrix is prepared from a material mixture of vinegar residue, cassava residue and crop straw powder which are subjected to fermenting and composting, minced coco coir, plant ash, peat and pearlite and is characterized by being prepared from the ingredients in parts by volume: 3-6 parts of vinegar residue, cassava residue and straw powder mixed organic fermented material, 1-2 parts of minced coco coir, 1-2 parts of plant ash, 1-2 parts of peat, 0.5-1 part of pearlite and a ternary compound fertilizer, of which the weight is 0.2-0.5% of the total weight; the matrix has the characteristics that the grain size is not greater than 5mm, the moisture content is 35-50%, the total porosity is 65-75%, and the volume weight is 0.35-0.5g / ml; in a dry matrix, the content of organic matters is not lower than 30%, the content of total nutrients is 2-3%, the EC value is 1.0-2.0sM / cm, the gas-water ratio is 1:(2-4), and the pH is 5.5-7.0; the matrix is granular solid, of which the appearance is dark-brown or black-brown, and is odorless. The lightweight matrix disclosed by the invention is loose in texture, light in specific weight and high in nutrient and is very applicable to the sky-rise greenery, such as urban primary road guardrails and pedestrian overpasses.

Description

technical field [0001] The invention relates to a horticultural substrate, in particular to a lightweight substrate for aerial greening, and belongs to the field of soilless cultivation horticultural substrates. 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 flower seedlings or melons, fruits and vegetables. It is a high-yield, high-quality advanced technology that saves water, fertilizer and labor. 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. [0003] Aerial greening is also called three-dimensiona...
