Description
Technical Field
The invention belongs to the field of flower container materials, and relates to a degradable flowerpot capable of adjusting humidity and a preparation method thereof.
Background
The flowerpot is a vessel for planting flowers, is in the shape of an inverted round table or an inverted pyramid table with a large opening and a small bottom, and can be divided into a plurality of types according to different manufacturing materials. Porcelain basins, glass fiber reinforced plastic flowerpots, plastic basins, purple sand basins and the like are commonly used. The process of the porcelain basin, for example, roughly needs to go through the steps of pugging, throwing, carving, glazing, burning and the like, and is complex and energy-consuming. The glass flowerpot is also complex in preparation process, and is impermeable to air and moisture. The plastic flowerpot is relatively simple in preparation process, but the plastic flowerpot is not breathable and mainly used for soilless culture, and the cost of the plastic flowerpot is lower than that of glass and ceramic flowerpots.
In municipal works, since the survival rate of transplanting of many flowers and plants is about 80-90%, the survival rate is also reduced in the case of unreasonable maintenance and improper transplanting time, and the low survival rate results in secondary transplanting and increases municipal investment costs, and thus, it is a general pursuit of municipal works to increase the success rate of transplanting flowers or plants. The factors influencing the transplanting survival rate of flowers or plants comprise the humidity in the soil, and when the humidity in the soil is moderate and the soil is soft, the rooting of the plants and the survival rate improvement are facilitated.
The invention aims to prepare a flowerpot for improving the transplanting survival rate of flower plants, the flowerpot can ensure that the soil is soft, can provide organic fertilizer, ensures that the soil is soft, does not need to be removed in the transplanting process, avoids the damage of the root systems of the flower plants, and further improves the survival rate of the flowers or the plants.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a degradable flowerpot capable of adjusting humidity and a preparation method thereof.
The raw material bag of the flowerpot consists of epoxy resin glue, soil, quartz sand or mineral powder, an active diluent, a curing agent, a biomass material and a water-containing microcapsule, wherein the biomass material is straw or wood dust.
The specific flowerpot comprises the following raw materials in parts by weight: 20-30 parts of epoxy resin, 2-10 parts of reactive diluent, 0-3 parts of inorganic pigment, 25-35 parts of quartz sand, 1-3 parts of coupling agent, 5-20 parts of biomass raw material, 5-20 parts of water-containing microcapsule and 2-10 parts of curing agent.
The particle size of the biomass raw material after being crushed is less than 500 mu m.
The biomass raw material is straw or sawdust, the straw comprises the rest part after crop production and harvest, the straw comprises wheat straw, rice straw, corn stalk, cotton stalk, rape stalk, sugarcane stalk and the like, the biomass raw material must be smashed, and the particle size is less than 500 mu m, so that the surface smoothness and the attractiveness of the flowerpot can be ensured, if the smashed biomass raw material has too large particle size, the density of biomass particles is much smaller than that of sandstone, in the mixing process of powder, the biomass material is not easy to be uniformly blended, the slurry is easy to be non-uniformly mixed, and more holes are easy to be formed in the flowerpot after forming, the moisture retention performance and the mechanical property of the flowerpot are greatly influenced.
The biomass material is easily decomposed by microorganisms in soil under natural environment, and then is decomposed into organic fertilizer, can provide necessary organic fertilizer for flowers to a certain extent, is favorable for the growth of the flowers, and meanwhile, the decomposed biomass material can effectively lock moisture due to looseness, can also remove accumulated water, and achieves the effect of effectively adjusting humidity.
The invention uses the epoxy resin as the binding agent, and because the density of the biomass material is smaller than that of the sand, the biomass material is difficult to be uniformly mixed in the process of mixing powder. Epoxy resins also improve their flexibility.
Because the invention uses a large amount of biomass materials, the biomass materials can be decomposed and converted into organic fertilizers and can be easily absorbed by plants, after the flowerpot is decomposed, the biomass materials and the epoxy resin can be split, and finally the flowerpot can form a three-dimensional net-shaped structure, and the three-dimensional net-shaped structure can not bring great adverse effect on the root system development of flowers or plants.
Because the biomass degradable material provided by the invention can be effectively degraded, when flowers or plants are transplanted, the flowers and the fabrics are only needed to be buried in the way, the damage to the root systems of the flowers or the plants is avoided, and the survival rate can be further improved.
In the flowerpot, the invention creatively uses the water-containing microcapsule.
The skin layer of the water-containing microcapsule is calcium alginate, and the core layer is water-containing solution.
The invention uses the water-containing microcapsule which can lock water, the cortex of the water-containing microcapsule is calcium alginate, the surface layer of the microcapsule has tiny micropores, the water-containing solution of the core layer can slowly permeate out, and when the water content is more, the water content of the outer layer can also slowly permeate into the core layer, thereby achieving the purpose of adjusting the humidity of the soil. When flowers and plants are transplanted, the main factor influencing the survival rate of the flowers or the plants is also the humidity factor of the soil, and the invention creatively uses the water-containing microcapsule, can effectively regulate the humidity of the soil during the transplanting period, and is beneficial to the rooting of the plants as soon as possible and the adaptation to the soil environment. Calcium alginate is also degraded for a long time, and can be converted into organic fertilizer after being degraded.
The volume of the microcapsule is 0.5-5 mm.
The core layer of the water-containing microcapsule used in the invention is water-containing solution, wherein trace elements such as K, N, P and the like can be added into the core layer to promote the growth of the roots of flowers or plants.
