Embodiment 1
[0021] A cuttage matrix for flower seedlings, composed of vinegar grains, cassava residues, vermiculite, peat and plant ash, characterized in that: the volume ratio of the matrix formula components is: 50% vinegar grains, 15% cassava residues, 10% plant ash, leech Stone 15%, peat 10%. The matrix has a water content of 25-40%, a total porosity of 65-90%, an organic matter content of ≥20%, a total nutrient content of 1-3%, a particle size of 0.1-3.5mm, and a bulk density of 0.2-0.8g / cm 3 , the air-water ratio is 1:2-4, the EC value is 1-3mS / cm, and the pH is 6.
[0022] The substrate fermentation treatment is to compost and decompose vinegar grains and cassava residues with a high-temperature quick-rot agent, and the composting time is 130 days; the dosage of the high-temperature quick-rot agent is 15-20 kg of the quick-rot agent per 100 m3 of raw materials.

Abstract
The invention discloses a flower seedling wood cutting medium, and belongs to the technical field of soilless culture. The medium comprises the following components in percentage by volume: 30 to 50 percent of vinegar residues, 10 to 20 percent of manioc waste, 10 to 15 percent of plant ash, 10 to 20 percent of vermiculite, 10 to 20 percent of turf, wherein the water content of the medium is between 25 and 40 percent, the total porosity is between 65 and 90 percent, the organic matter content is more than or equal to 20 percent, the total nutrition content is between 1 and 3 percent, the grain diameter is between 0.1 and 3.5mm, the volume weight is between 0.2 and 0.8g/cm3, the gas-water ratio is 1:(2-4), the EC (nutrient liquid concentration) value is between 1 and 3mS/cm, and the pH is between 6 and 7.5. According to the flower seedling wood cutting medium, organic wastes are mainly used as raw materials and fermented at high temperature to produce soilless culture medium, so that waste materials are changed into valuable things, and harmful substances are changed into benefits things. The medium is low in cost, light in weight and comprehensive in nutrition, is suitable for flower seedling wood cutting seedling, and is an excellent medium for soilless culture of garden crops.
Description
technical field [0001] The invention relates to a soilless culture substrate for horticultural crops, in particular to a cutting substrate for flower seedlings, and belongs 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 flower seedlings or melons, fruits and vegetables. 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 applic...
