Problems solved by technology

Although a small number of patents have the report of continuous integrated matrix, as in the publication number CN105325269A, foamed cement is used as the matrix, and porous inorganic substances such as perlite are filled to make a hard cultivation matrix body, but it has high strength, low porosity, and water retention. Insufficient water absorption rate and the need to use nutrient solution, etc., cannot solve the relationship between water, air and nutrients required for plant growth

Embodiment 1

[0029] Add 5 parts of difunctional polyether polyols with EO content of 80% and average molecular weights of 800 and 4800 respectively into a closed reaction kettle, and vacuum dehydrate at 100-120°C for 2 hours; cool the above polyether polyols to 50 ℃, add 2.6 parts of TDI, raise the temperature to 80 ℃ within 40 minutes and react for 1.5 hours to obtain the desired prepolymer; the isocyanate content in the prepolymer is 6.8%~8.5%.

[0030] 3 parts of loess, 10 parts of peat soil, and 2 parts of straw crushed and mixed are counted as filler material A; 20 parts of water, 0.5 parts of alkyl glucoside, and 8 parts of melamine formal resin are mixed at high speed and counted as small material B; 0.1 part of soil disinfection Agent, 0.5 parts of formic acid, and 5 parts of grass seeds are counted as pre-embedded functional material C material. Mix A material and C material evenly with water. After mixing, spray it on the slope that has been leveled and reinforced, foam at normal...

Embodiment 2

[0032] Prepare required prepolymer by the method of embodiment 1;

[0033] In 20 parts of water, add 1 part of chicken manure, 2 parts of diatomaceous earth, 10 parts of bagasse, and 0.5 part of humic acid, all of which have been pulverized, and mix them evenly to obtain the filler as material A; 10 parts of water, 0.1 part of fatty alcohol poly The small material obtained by mixing oxyethylene ether, 0.1 part of fatty alcohol and 1 part of triethanolamine is counted as material B; 0.1 part of rooting agent is counted as material C of pre-embedded functional substances. After fully stirring, mixing and dispersing material A, material B and material C, add 6 parts of prepolymer, stir quickly and pour into a flower pot-shaped plastic mold, naturally foam 3~8 times within 20 minutes, and place it for 24 hours After aging, the porous soil imitation cultivation matrix body is obtained. After the matrix is ​​dried, the dry weight is measured as 0.21 ~ 0.32g / cm 3 ,The saturated wa...

Embodiment 3

[0035] Prepare polyurethane prepolymer according to embodiment 1 method;

[0036] In 20 parts of water, add 1 part of chicken manure, 2 parts of sheep manure, 10 parts of mushroom dregs, and 10 parts of melamine resin that have been pulverized, and mix evenly to obtain the filler as material A; 10 parts of water, 0.1 part of fatty alcohol polyoxygen The small material obtained by mixing vinyl ether, 0.1 part of fatty alcohol and 1 part of hydrochloric acid is counted as material B; 0.1 part of ammonium chloride is counted as material C of the pre-embedded functional substance. After fully stirring, mixing and inflating material A, material B and material C, add 1 part of prepolymer, stir quickly and pour it into a flowerpot-shaped plastic mold, naturally foam 1~3 times within 20 minutes, and place it for 24 hours After aging, the porous soil imitation cultivation matrix body is obtained. After the matrix is ​​dried, the dry weight is measured as 0.21 ~ 0.32g / cm 3 , The satu...

Abstract

The invention discloses an environment-friendly light porous simulated soil cultivation medium body and a preparation method thereof. The cultivation medium body is of a continuous integrated porous simulated soil sponge structure and is prepared from 1-10 parts by weight of polyurethane binding body, 1-50 parts by weight of filler, 0.01-50 parts by weight of auxiliary material and 0-5 parts by weight of embedded functional matter. The filler is at least one of organic filler, inorganic filler and organic and inorganic composite filler. The auxiliary material is a mixture of at least two of a surface active agent, a catalyst, a chain extender, a fire retardant and a foaming agent. The embedded functional matter is at least one of plant seeds, a rooting agent, a soil sanitizer, a straw fermenting agent, potash fertilizer, phosphatic fertilizer, nitrogenous fertilizer and compound fertilizer. The prepared simulated soil cultivation medium body is low in weight, high in aperture ratio, good in hydrophilia and water retention performance and excellent in mechanical property, and can be applied to the fields of vertical greening, roof greening, urban landscaping, indoor greening, intelligent greening, slope restoration, gardens and horticulture, ecological remediation, ecological management, soilless culture and the like.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation substrates, in particular to an environmentally friendly and portable porous soil imitation cultivation substrate and a preparation method thereof. Background technique [0002] Solid substrates can be divided into organic substrates (natural such as sawdust, bark, non-woven fabrics, straw fiber non-woven fabrics, etc.), inorganic substrates (granular ones such as ceramsite; foamy ones such as volcanic lava; fibrous ones such as rock Cotton, sponge; others such as silica gel), formula matrix (inorganic-inorganic type such as ceramsite + perlite; organic-organic type such as peat + bubble flower; inorganic-organic type such as peat + perlite) (Xie Xiaoyu , Zou Zhirong. Research progress of soilless cultivation substrates for vegetables in China. China Agronomy Bulletin, 2005,21:280-283). Inorganic substrate basically does not contain nutrients, has no biological activity, and can basical...
