Planting soil suitable for ulmus parvifolia

Abstract

The invention relates to the technical field of plant planting, in particular to planting soil suitable for ulmus parvifolia. The planting soil is characterized by being prepared from, by weight, 500-600 parts of modified coal cinder, 40-60 parts of fertilizer, 80-90 parts of peat soil, 60-70 parts of limestone and 55-80 parts of borax; the fertilizer is prepared from 25-30 parts of phosphorus pentoxide, 8-9 parts of potassium fulvate, 0.5-1 part of microelement, 3-6 parts of calcium sulfate and 1-2 parts of vitamins. Coal cinder is modified and sufficiently combusted to remove sulfur and dust in the coal cinder and neutralize alkalinity of the coal cinder, so that the coal cinder is suitable for ulmus parvifolia growth. The planting soil is ventilated, pervious to water and low in cost, and contains abundant microelements such as ferric oxide, calcium oxide and magnesium oxide and a great deal of combusted stone and loess and other media needed by planting, and germ residue is avoided basically due to high-temperature combustion. The planting soil is obtained through waste reuse, provides nutrition for ulmus parvifolia growth for a long time, can effectively simulate ulmus parvifolia germination and growth and does not pollute the environment.

Description

Technical field: [0001] The invention relates to the technical field of plant planting, in particular to a planting soil suitable for elm elm. Background technique: [0002] Nut elm, another name: small leaf elm. The shape of the tree is graceful, the posture is unrestrained, the bark is mottled, and the branches and leaves are fine and dense. It is very suitable to be planted alone or in clusters in the courtyard, or arranged with pavilions, mountains and rocks. It is also commonly used in potted plants now. [0003] Coal slag, a kind of industrial solid waste, is the waste slag discharged from thermal power plants, industrial and civil boilers and other equipment burning coal, also known as slag. The main components are silica, alumina, iron oxide, calcium oxide, magnesium oxide, etc. Because of its low price and rich in various elements, it is also commonly used to plant plants, but cinder plants have the following disadvantages: [0004] 1. After burning, the sulfur an...

Problems solved by technology

[0005] 2. Some briquettes have not been fully burned, resulting in more black particles produced during screening, which is harmful to plant roots;

[0006] 3. There is too much dust in the cinder. If it is used directly with soil, sometimes the root system will cause rotten roots or the probability of rot because of the airtightness of the root system.
