Special environment-friendly culture soil for urban families

Abstract

The invention relates to culture soil, in particular to special environment-friendly culture soil for urban families. The special environment-friendly culture soil for urban families is prepared by mixing 25-45 percent of matrix with 55-75 percent of rural soil or clay in percentage by weight. The matrix contains 60-80 percent of organic matter including the following components by weight: 1-3 percent of nitrogen, 1.5-3.5 percent of phosphorus, 2-4 percent of potassium and 0.02-0.08 percent of trace magnesium, calcium, ferrum, manganese and boron. The pH value of the matrix is 6.5-6.8, the conductivity is 1.5-3.5 S, and the cation exchange capacity is at least 100. The organic matter contains 1-3 parts of starch-acrylic acid graft copolymer, 15-40 parts of straw decomposing inoculant, 15-40 parts of fermented human and animal excreta, 10-18 parts of edible fungi residue, 3-6 parts of waste bamboo shavings, 2-5 parts of plant charcoal powder, 5-10 parts of sludge residue, 4-6 parts of bone meal and 4-9 parts of bean pulp. Specific components and proportion are adopted to be matched to prepare the organic matter, and the organic matter is combined with inorganic matters to form the weak-acid matrix, so that the nutritional ingredient is high, and the proportion of trace elements is appropriate. The culture soil has a good flavor removing function, so that foreign flavor is avoided when urban families grow plants such as vegetables, and the culture soil is clean and environment-friendly.

Description

technical field [0001] The invention relates to a cultivation soil, in particular to a special environment-friendly cultivation soil for urban households. 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.
