Seedling-cultivating substrate soil for micro agriculture

Abstract

The invention relates to cultivation soil, in particular to seedling-cultivating substrate soil for micro agriculture. The seedling-cultivating substrate soil is formed by mixing a substrate with rural soil or clay and comprises the following components in weight percent: 25% to 45% of the substrate and 55% to 75% of the rural soil or clay; the substrate comprises 60% to 80% of organic matters in weight percent and includes 1% to 3% of nitrogen, 1.5% to 3.5% phosphorus, 2% to 4% of potassium, and 0.02% to 0.8% of trace elements including magnesium, calcium, iron, manganese and boron; the pH value of the substrate is 6.5 to 6.8; the organic matters comprise 1 to 4 parts of bamboo vinegar liquid, 1 to 3 parts of starch-acrylic acid graft copolymer, 15 to 40 parts of a straw decomposition agent, 15 to 40 parts of fermented human and animal excreta, 10 to 18 parts of edible fungus residue, 3 to 6 parts of waste bamboo, 2 to 5 parts of plant-charcoal powder, 5 to 10 parts of silt slag, 4 to 6 parts of bone meal and 4 to 9 parts of soybean meal. According to the invention, specific components and proportion are adopted to prepare the organic matters, and the organic matters are combined with inorganic matters to form the acidulous substrate, so that the seedling-cultivating substrate soil is high in nutritional ingredient and appropriate in proportion of trace elements, has an excellent odor removing effect, and avoids undesirable odors produced during planting of vegetables and other plants for urban families.

Description

technical field [0001] The invention relates to a culture soil, in particular to a micro-agricultural seedling raising matrix soil. Background technique [0002] Along with the rapid development of cities, with the continuous improvement of people's living standards, and people's strong demand for pastoral, rural and green food, agricultural products that do not use pesticides, chemical fertilizers, and hormones, urban residents yearn for pastoral and green The need for food, makes them in great demand for micro-farming. Compared with rural areas, there are more restrictive conditions for the development of modern agriculture in cities. As a result, many urban residents plant vegetables and fruits on balconies, plant vegetables and fruits on vacant land in urban communities, and on relatively open places such as high-rise buildings and roofs in cities.
