Indoor air purification plant cultivation medium

Abstract

The invention discloses an indoor air purification plant cultivation medium which is prepared from the following raw materials in parts by weight: 35 to 38 parts of coconut coir, 12 to 15 parts of cassava residues, 4 to 5 parts of potassium oxide, 2 to 4 parts of calcium formate, 1 to 2 parts of grafting acrylamide, 2 to 3 parts of chitosan, 4 to 5 parts of activated carbon powder, 2 to 3 parts of fine lignin powder, 26 to 28 parts of sunflower disc powder residues, 38 to 42 parts of snakeskin waste, 1.6 to 1.9 parts of a pepsin preparation, 1.2 to 1.4 parts of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, 0.4 to 0.5 part of N-hydroxysuccinimide, a proper amount of a 4% sodium chloride solution, a proper amount of a 0.15mol / L citrate solution and a proper amount of water. The cultivation medium is suitable for cultivating indoor plants; harmful gas such as formaldehyde in a room can be effectively adsorbed by the activated carbon powder, the fine lignin powder and the like, meanwhile, the chitosan, collagens and the like are matched for polymerization with the harmful gas, and the advantages are mutually complemented to convert harmful molecules of the formaldehyde and the like into carbohydrates to implement indoor air purification by virtue of catalysis and fermentation of the added proteases for generation of microorganisms, so that the utilization value of indoor plant cultivation is improved.

Description

technical field [0001] The invention relates to the technical field of nutrient substrates, in particular to a plant cultivation substrate for indoor air purification. Background technique [0002] Substrate cultivation is an important cultivation method in my country's current agriculture, forestry, and plant planting industries. It is a soilless cultivation method that absorbs nutrient solution and oxygen through the substrate. The advantages of saving water and fertilizer have been adopted and applied by the majority of planting producers. With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. During the stage, the substrate generally has a single nutrient, resulting in low germination rate and low survival rate ...

Problems solved by technology

At the same time, our country is rich in snake resources. Due to the clear and bright patterns on the appearance of snake skin and unique patterns, it is used to make various exquisite handicrafts. If 20-30% of snake skin is not effectively treated, it will not only pollute the environment, but also waste a lot of raw materials. Snake skin contains a lot of collagen, which also provides a cheap raw material basis for its application in matrix preparation.

[0004] The invention patent application with publication number CN1702061A discloses a kind of plant seedling raising and cultivation full nutrient substrate, and this nutrient substrate adopts the peat of 50-70% by weight, the perlite of 20-25%, the vermiculite of 10-15% and Active substances and nutrients are mixed, and have a relatively comprehensive nutrient composition. However, the cultivation substrate disclosed in the invention has different particle sizes, and it is easy to cause sedimentation after watering, resulting in blockage of the air in the substrate. At the same time, the crude fiber in the substrate The content is low, which requires the addition of additional nutrients, which increases the production cost, and does not increase the additional use value of the substrate according to the specific needs of cultivation, which limits the large-scale application of the product
