preparation example Construction

[0050] The preparation method of the above-mentioned airgel self-suspension soilless culture substrate, specifically, comprises the following steps:

[0051] (1) Disperse the airgel powder, water, and surface wetting agent in a certain proportion using a high-speed disperser to a uniform dispersion;

[0052] (2) Add a viscosifier to the dispersion prepared in (1) and mix evenly with a mixer to form an airgel self-suspension soilless cultivation substrate.

[0053] Preferably, the density of the airgel self-suspension soilless cultivation substrate prepared in the step (2) is between 0.3-0.8 g / ml, and the surface water contact angle is >120°.

[0054] In step (1), the dispersing and stirring speed of the high-speed disperser is 900-1500rp, and the dispersing time is 30-120 minutes.

[0055] In step (2), the stirring speed of the stirrer is between 120~500rpm, and the stirring time is between 30~120 minutes

[0056] The soilless culture device that utilizes the airgel that the...

Embodiment 1

[0062] A kind of preparation method of airgel self-suspension soilless cultivation substrate, its steps are as follows:

[0063] (1) Disperse 20 parts by weight of silica airgel powder, 80 parts of water, and 0.1 part of sodium dodecylsulfonate at 1400 rpm for 60 minutes using a highly dispersing machine, wherein the particle size of silica airgel powder Between 10 and 50 μm, the surface water contact angle is 145°, and the density is 0.05g / ml

[0064] (2) Add 2 parts by weight of sodium alginate to the dispersion prepared in (1), and stir for 30 minutes with a horizontal mixer to obtain an airgel self-suspension soilless cultivation substrate.

Embodiment 2

[0066] A kind of preparation method of airgel self-suspension soilless cultivation substrate, its steps are as follows:

[0067] (1) Disperse 10 parts by weight of silica airgel powder, 90 parts of water, and 0.05 part of sodium dodecylsulfonate at 1400 rpm for 60 minutes using a highly dispersing machine, wherein the particle size of silica airgel powder Between 10 and 50 μm, the surface water contact angle is 145°, and the density is 0.05g / ml

[0068] (2) Add 3 parts by weight of sodium alginate to the dispersion prepared in (1), and stir for 30 minutes with a horizontal mixer to obtain an airgel self-suspension soilless cultivation substrate.

Abstract

The invention discloses an aerogel-containing self-suspended soilless culture medium, and relates to the field of soilless culture media. The aerogel-containing self-suspended soilless culture mediumcomprises, by weight, 1-30 parts of aerogel powder, 70-99 parts of water, 0.05-0.1 part of surface emollient and 2-10 parts of tackifiers. The aerogel-containing self-suspended soilless culture mediumhas the advantages that the moisture content of the medium can be effectively increased and controlled by adding the aerogel powder to the medium, the interfacial compatibility between the aerogel powder and other components can be improved through the synergistic effect of the surface emollient in the components, and the stability of the overall structure of the medium can be improved. The invention further discloses a preparation method. The preparation method is simple and easy to operate, no waste or pollutant is generated during production, and environment protection is achieved. The invention further discloses a soilless culture device. The soilless culture device produced by using the aerogel-containing self-suspended soilless culture medium is simple in structure, free of pollution, and convenient for planting and cultivating of plants.

Description

technical field [0001] The invention belongs to the field of cultivation substrates, and in particular relates to a soilless cultivation substrate, a preparation method and a soilless cultivation device. Background technique [0002] Soilless cultivation refers to the technology of cultivating crops and seedlings using artificially configured substrates instead of natural soil. At present, soilless cultivation technology has been applied to seedlings, flowers, fruits and vegetables, which is a water-saving and economical method. Advanced cultivation technology that saves fat and labor. The characteristics and advantages of soilless cultivation technology have been familiar and recognized by the majority of researchers and producers. [0003] At present, soilless culture substrates are divided into inorganic substrates, organic substrates and mixed substrates. Such as ceramsite, peat, foam, perlite, sawdust, etc. are used as substrates for soilless cultivation. However, th...
