Description
Technical field
The present invention relates to agriculture apparatus fields, and in particular to a kind of degradable sludge base pot for growing seedlings and preparation method thereof.
Background technology
Pot for growing seedlings is chiefly used in the fields such as nursery, breeding and greenhouse gardening and the afforestation of agricultural, is widely used, demand
Amount is big.In practical seedling raising process, transplanting is an extremely important step, need by pot for growing seedlings seedling and nutritive cube take
Continued growth in plantation to crop field or large-scale flowerpot after going out.Seedling culture bowl is needed to be carried out with pot for growing seedlings during transplanting
Technical problems, the surviving after strong influence seedling replanting such as there is damage seedlings root and seedling culture bowl be fugitive in separation
Rate.The making raw material of degradable pot for growing seedlings has shale, wooden and degradation plastic etc. at present, but these degradation materials are still
There are problems that：Shale pot for growing seedlings, degradation speed is slow, preparation process high energy consumption, and environment friendly is poor；The system of wooden pot for growing seedlings
Standby cost is few compared with high application；Degradation plastic pot for growing seedlings, technique is cumbersome, of high cost；Therefore, it is used to prepare nursery capable of being fast degraded
The material of alms bowl becomes new research hotspot.
With the development in cities and towns, the yield of municipal sludge is increasing, but resource utilization rate is low, is brought to environment huge
The recycling of big harm, sludge is the most ideal outlet of Treatment of Sludge.Containing by innoxious sludge largely has
Machine matter and mineral nutrient, the sludge after harmless treatment can be used for land use, agricultural compost, soil remediation etc., change soil
Earth physicochemical property promotes to play an important roll in terms of farm-forestry crop volume increase.Therefore, it is prepared using innoxious sludge as raw material
Degradable pot for growing seedlings, seedling can be transplanted together with pot for growing seedlings during transplanting, to avoid the damage of seedlings root
Wound and seedling cultivate the fugitive problem of bowl, can improve the survival rate of seedling；Meanwhile the sludge base pot for growing seedlings after degradation can be with
The physicochemical property for changing soil, is conducive to the growth of seedling, increases economic efficiency.
Since the growing-seedling period of plant is generally shorter, just it will be transplanted or be colonized after the completion of nursery, transplanted or be colonized
Plant root is needed to grow and extend to meet the needs of plant fast-growth as soon as possible afterwards, it is therefore desirable to which pot for growing seedlings is being transplanted
Or can degrade in a short period of time after field planting, to release the limitation that pot for growing seedlings extends to plant root.However, existing correlation
The degradable pot for growing seedlings prepared with sludge in data and patent, although equally there is degradable characteristic, due to matching for use
Side or preparation method etc. it is unreasonable, cause the degradation time of pot for growing seedlings longer, seriously limit the quick of plant shoots root system
Growth and extension, impact the fast-growth of plant after transplanting.
Invention content
It is an object of the invention to overcome the shortcomings of that the degradation time present in existing pot for growing seedlings is long, providing one kind can drop
Sludge base pot for growing seedlings and preparation method thereof is solved, which is to adjust by the specific aim to formula and match with preparation method
What conjunction was prepared；The pot for growing seedlings not only has higher mechanical property, can meet in nursery to pot for growing seedlings performance
It is required that；Can also fast degradation in the soil, to which fast-growth and the extension of plant root will not be limited after transplanting or field planting,
There is positive effect to improving the survival rate of seedling and the growth rate of plant.
In order to achieve the above-mentioned object of the invention, the present invention provides a kind of degradable sludge base pot for growing seedlings, including following weight
Part raw material are prepared：2-5 parts of polyvinyl alcohol, 80-100 parts of water, 5-10 parts of gelatin, 5-10 parts of dextrin, 5-20
The sludge of part, 0.5-1 parts of crosslinking agent；The pot for growing seedlings in preparation process forming processes prior to crosslinking Treatment.
A kind of degradable sludge base pot for growing seedlings of the present invention, by targetedly selecting degradable raw material, and limits it
Dosage makes raw material have excellent processing forming in preparation process, crosslinked can form pot for growing seedlings in the case that no
Germule；Again by crosslinking Treatment after molding, cross-linking reaction is set only to be carried out on the surface of pot for growing seedlings, to which pot for growing seedlings can be improved
Mechanical property, and can prevent from being excessively crosslinked inside pot for growing seedlings, the degradation time of pot for growing seedlings in the soil is made significantly to shorten,
Pot for growing seedlings will not limit the fast-growth of plant root and extension, can improve the survival rate of seedling and the growth speed of plant
Rate.
Wherein, the polyvinyl alcohol has degradability, can carry out cross-linking reaction with crosslinking agent, be degradable pot for growing seedlings
Framework material, and the degree of polymerization of polyvinyl alcohol influences the viscosity and mechanical property of polyvinyl alcohol, has to the overall performance of pot for growing seedlings
There is large effect；Preferably, the polyvinyl alcohol degree of polymerization is 500-2000；The polyvinyl alcohol of the degree of polymerization both have compared with
Good mechanical property and viscosity, is conducive to the molding of pot for growing seedlings, so as to get pot for growing seedlings mechanical property it is preferable, and will not be because poly-
It is right excessively high, cause the degradation speed of pot for growing seedlings to reduce；Most preferably, the polyvinyl alcohol degree of polymerization is 1000-1500.
Wherein, the gelatin and dextrin are conducive to the molding of pot for growing seedlings, can improve pot for growing seedlings as material binder
Mechanical property, and derive from a wealth of sources, degradation speed is slower in air, and degradation speed is fast in the soil.
Wherein, the sludge is the sludge by harmless treatment, containing a large amount of organic matter and mineral nutrient, to planting
The growth of strain has facilitation.
Wherein, the crosslinking agent refers to the material that cross-linking reaction can be carried out with raw material, and cross-linking reaction can significantly improve
The mechanical property and chemical stability of pot for growing seedlings, while can also extend the degradation time of pot for growing seedlings；Preferably, the crosslinking agent
