Abstract
A mixed resin cultivating and seedling-raising medium is prepared by evenly mixing, by weight, 20%-35% of starch resin foam particles, 15%-35% of urea resin foam particles and 30%-50% of wood fibers. According to the mixed resin cultivating and seedling-raising medium, perlite and vermiculite are replaced with the starch resin foam particles and the urea resin foam particles, the water storage property and water retaining property of the medium are greatly improved, degradation of the medium itself in the future is convenient, and overexploitation of perlite and vermiculite is avoided; in addition, a small amount of residual formaldehyde exists in the machining process of urea resin foam and can promote fermentation of the wood fibers, so that the wood fibers are converted into nutrient substances capable of being absorbed by plants more rapidly.
Description
Technical field:
The present invention relates to cultivation and seedling medium technical field, particularly to a kind of hybrid resin cultivation and nursery
Substrate.
Background technology:
Soilless culture (soiless culture) refer to without natural soil with substrate or only nursery time substrate,
After field planting, carry out the cultural method irrigated with nutritional solution, can Economization on land, owing to soilless culture can be artificial
Create good rhizospheric environment, effectively prevent soil from even doing disease and soil salt accumulates the physiological barrier caused,
Fully meet the crop needs to environmental conditions such as mineral nutrition, moisture, air, the stock of cultivation
Can recycle again, therefore there is water-saving, save the features such as fertilizer, saving of labor, high yield and high quality.
After living through whole nation snow disaster on a large scale in 2010, industrial seedling rearing gradually by many agricultural aspects insighted it
Scholar accepts, and this has been also greatly facilitate the research of application aspect of seedling medium.Use more host material
There are peat, rock wool, Vermiculitum, perlite, bagasse, mushroom slag, grit and haydite etc..Rock wool and peat at present
Most widely used general in the whole world, it is the comparatively ideal cultivation matrix generally acknowledged in the world.But along with using the most in a large number,
Its negative effect bringing to society and ecological environment also becomes clear day by day, on the one hand due to rock wool non-degradable,
A large amount of use brings secondary pollution to environment；On the other hand, peat is non-renewable resource, opening of excess
Adopt the danger of exhaustion；Therefore, seek and excavate the excellent of the materials such as peat inexpensive, alternative, rock wool that be easy to get
Good Novel seedling raising substrate has become one of current researcher study hotspot.
Abroad have been developed for the organic substrates such as cocoanut fiber, bark, wood sawdust, not only can significantly drop
Low cultivation cost, and decrease the pollution to environment.Substrate research is started late by China, " gather materials on the spot,
Treatment in accordance with local conditions research and development " become common recognition, as strengthened on the south the Changjiang river that the reasonable employment after charred rice husk is ground
Study carefully；Slag is strengthened in North China, and coordinates the research of the material mixing uses such as the peat composed of rotten mosses, Vermiculitum, sawdust；Northeast adds
The strong research to the peat composed of rotten mosses, sawdust etc.；And in Shandong, Jiangsu, have studied with treasure Henan one band treatment in accordance with local conditions
The seedling medium products such as Zhu Yan, Vermiculitum, the peat composed of rotten mosses have obtained bigger popularization；Great Northwest is then strengthened sand culture
The research etc. of technology.More domestic scientific research institutions have more or less carried out substrate developmental research, have been enter into
Practical stage, but relatively costly, consume resource seriously, and wherein replace Margarita with starch-resin foam beads
Rock and Vermiculitum, replace the research report that the peat composed of rotten mosses, production nursery or cultivation are matrix body material not have with the wood fiber
See.
Starch-resin has the strongest water absorbing capacity, can absorb sole mass tens times or even the water of hundred times,
This is that conventional any absorbent material is incomparable, and water holding capacity is the highest, after water suction, no matter applies
Great pressure is not dehydrated, and be therefore otherwise known as high water-retaining agent, and meanwhile, starch-resin can in the short time certainly
So degraded, is the material of a kind of environmental protection.As the main component of starch-resin, starch source extensively,
Cheap, be suitable for large-scale processing.
Summary of the invention:
In consideration of it, be necessary the design a kind of mixing without the peat composed of rotten mosses, Vermiculitum, perlite and urea formaldehyde resin foam
Resin cultivation and seedling medium.
A kind of hybrid resin cultivation and seedling medium, uniformly mixed by the raw material of following percentage by weight and form:
Starch-resin foam particle 20～35%, urea formaldehyde resin foam particle 15～35%, the wood fiber 30～50%；
Described starch-resin foam particle preparation method comprises the following steps:
(1) take 200～300 parts of Polyethylene Glycol and 180～240 parts of glycerol, 9～11 parts of methanesulfonic acids add with
In the oil bath interlayer retort of condensation reflux unit (i.e. this retort is with interlayer, for oil bath in interlayer), add
Heat also starts agitating device, is heated to 155～165 DEG C, adds 40～80 parts of starch, and stirring reacts 40～50min,
It is cooled to 20～35 DEG C, sends into centrifuge, be centrifuged off solid catalyst, obtain starch liquefacation product；
(2) above-mentioned starch liquefacation product being sent into retort 80 parts, add 1 part of water simultaneously, 0.2～0.4 part double
The kicker of the dibutyl tin laurate composition of dimethylaminoethyl ether and 0.1 part, 7 parts of silicone oil L580,
Starting agitating device, add 120～150 part 4 at 10 DEG C, 4`-methyl diphenylene diisocyanate, at 7000r/min
Lower stirring 10S, pours in mould and solidifies, shapes, and the demoulding afterwards obtains starch-resin foam；
(3) by foam comminutor, the starch-resin foam that previous step obtains is fabricated to particle diameter be more than or equal to
1mm and the starch-resin foam particle less than or equal to 10mm；
Described urea formaldehyde resin foam particle preparation method: the formalin by 28% is adjusted with the sodium hydroxide of 20%
Formalin polycondensation reaction at 90 DEG C of carbamide and 28%, 5.8～6.4, is obtained urea in 1 hour by joint pH value
Urea formaldehyde solution, by sodium butylnaphthalenesulfonate and phosphoric acid mixed configuration expanding foam solution, stirring expanding foam solution produces a large amount of bubble
Join urea-formaldehyde resin solution after foam and continue stirring, obtain urea formaldehyde resin foam thing, finally by foam pelletize
Urea formaldehyde resin foam particle made by machine, and the particle diameter of urea formaldehyde resin foam particle is more than 3mm and less than 6mm.
The present invention starch-resin foam and urea formaldehyde resin foam replace perlite, Vermiculitum, significantly increase
The water storage of substrate and water-retaining property, facilitate again the degraded of substrate in the future itself, it also avoid to perlite,
The transition exploitation of Vermiculitum；It addition, urea formaldehyde resin foam work in-process remains a small amount of formaldehyde, it can promote wood
The fermentation of fiber, makes the wood fiber be changed into the nutrient substance that can be absorbed by plants faster.
