Soilless culture substrate with adjustable color and technique for producing the same

Abstract

The invention relates to a color adjustable soilless culture medium and a manufacture technology thereof, which belong to the technical field of culture mediums for home gardening and pot culture, in particular to a manufacture technology of a soilless culture medium capable of randomly changing color. The invention is characterized in that the medium is sphaerolitic, fine pore canals are distributed inside the medium, the colors of the medium can be configured to be constant inside and outside, and the manufacture of the medium is finished by eleven operation steps. The invention has the advantages that the medium is rich in color, does not corrode roots and emit odor and has good ventilation property, light texture, a certain strength support, strong water sopping and holding capabilities, stable chemical properties and suitable pH value as well as simple manufacture technology and low cost, thereby being applicable to the home pot culture as the soilless culture medium.

Description

technical field [0001] The invention belongs to the technical field of home gardening and cultivation substrate for potted plants, more precisely, it relates to a manufacturing technology of a soilless cultivation substrate whose color can be changed arbitrarily. Background technique [0002] At present, there are many kinds of materials that can be used as substrates for soilless cultivation of flowers, which can be roughly divided into organic substrates, inorganic substrates and artificial substrates according to the properties of materials. Organic substrates mainly include sawdust, rice husks, peat moss, bagasse, bark, pine needles, etc. Most of these substrates are composed of animal and plant residues, with complex chemical composition and unstable properties, which have a great impact on the nutrient solution, and the carbon-nitrogen ratio is very high in the initial stage of use, so they need to be fully composted and fermented before they can be planted. For famili...

Problems solved by technology

This kind of substrate has a wide range of sources, low price, good water and fertilizer retention capacity, and stable chemical properties, but it is very monotonous in terms of its appearance and color.

In addition, flower plants using crystal mud as a cultivation substrate were once popular, but they did not become the leading role in the end. The reason for this is related to the airtightness of crystal mud. It will rot soon under the sun. After a long time of use, the surface of the crystal mud will be easily contaminated with dust and become dirty. In addition, under the sun, the surface of the crystal mud will shrink due to water loss, which will affect the appearance.

[0003] I once proposed a patent application (application number: 200810032604.9) for "a color-adjustable soilless cultivation substrate manufacturing process" on January 14, 2008. The main principle is to utilize the reaction of sodium alginate and calcium chloride The formed gel film is used to wrap the perlite powder and silica gel powder, thus making a grainy, mung bean-like spherical matrix, but it was found in the actual cultivation later that the strength of this type of matrix is ​​very low, and alginic acid The gel film formed by sodium and calcium chloride will be gradually damaged, so the matrix will gradually change from the initial spherical shape to powder, and the service life will not exceed three months, so the practicability is poor
