Description
Technical field
The present invention relates to a kind of manufacture method of plant culture matrix and the plant culture matrix that obtains of method thus.
Background technology
As the plant cultured method, the most traditional is the method that adopts soil to cultivate.But along with the continuous deterioration of ball ecological environment and the continuous expansion of city size, brought increase day by day to the greening demand thereupon, if still adopt and in soil, carry out large-scale plant cultivation, and then with its transplantation with soil to the place that needs greening, can cause to the destruction of soil with to the destruction of ecotope.For example, cultivate the lawn with soil, draft the transplanting of carrying out the lawn again and carry training, will take away the ground surface soil of 3～5cm behind each turfing take, soil is after drafting for 5～7 times, and the arable layer that nutriment is rich on the face of land will be stripped from maltosemalt sugar to the greatest extent, and make it can't continue plantation.Therefore, the soilless cultivation method and the product of soil cultivation are more and more paid attention to by people as an alternative, also constantly occur its report of studying.For example, CN1323514A (applying date is July 9 calendar year 2001), CN1059819A (applying date is September 12 nineteen ninety) and ZL94224836.8 (applying date is on August 8th, 1994) disclose a kind of method, a kind of soilless cultivation device and a kind of soilless cultivation container of soil-less roof of building greening respectively.In these patent applications, the plant growing carrier of the soilless cultivation that is adopted mostly is composite carrier, for example, it is carrier that CN1323514A discloses with the polystyrene foam plastics, sawdust, bran chaff etc. in addition thereon again, for plant provides nutrient, other is aided with fixedly root system of plant of inorganic matrix; CN1059819A disclose have one deck on the surface of a plate or groove can be by the fiber of water infiltration, and below plate or groove, place the container of a holding liquid, the fiber on plate or the groove extends in the container.But this class does not have the device that earth culture plants and still exists structure complicated, is not easy to move, and is difficult to satisfy the shortcoming of the requirement of extensive high-efficient culture plant.
Summary of the invention

Manufacture method according to plant culture matrix of the present invention may further comprise the steps: (A) formaldehyde, urea, hexa, glycerine and absolute ethyl alcohol are mixed and carry out polycondensation reaction and be mixed with resin solution; (B) foaming agent solution of above-mentioned resin solution with preparation in advance mixed, supply in the frothing machine and bubble, generate foam matrix; (C) above-mentioned foam matrix is added to it is solidified and demoulding, oven dry; (D) foam matrix of oven dry is immersed preparation in advance be used for provide the immersion liquid of fertility to soak, dry then and (E) foam matrix of drying in (D) step cut into slices.
To be further described above steps below, in described step (A), formaldehyde with 15～25 weight portions, the urea of 8～13 weight portions, 0.3 the glycerine of～0.94 weight portion, 0.28 the hexa of～0.91 weight portion is added in the reactor, again to the absolute ethyl alcohol that wherein adds 0.063～0.155 weight portion, fully stir then, mix, the pH value of adjusting solution reaches 5～5.5, and is warming up to 98 ℃ of backflows, continue then 95～98 ℃ of reactions down, when the system viscosity of measuring reaches 0.021～0.041Pas, reactor is carried out the cold bath cooling, regulate pH value to 7.0～7.2.The gained resin is continued to be cooled to 20～30 ℃, and discharging adds suitable quantity of water and is diluted to 25～35% resin solution.
In described step (B), described foaming agent comprises the sodium butylnaphthalenesulfonate (the commodity powder that draws back by name) of 0.22～0.86 weight portion, the alkylsurfuric acid natrium surfactant of 0.047～0.42 weight portion, and the phosphoric acid of 0.28～1.77 weight portion.Hybrid mode to each component is not particularly limited, and can mix under normal temperature or heating, as long as can use after fully mixing.Wherein, described sodium alkyl sulfate is preferably lauryl sodium sulfate (commodity is called K
12) or sodium tetradecyl sulfate (commodity are called K
14), be preferably lauryl sodium sulfate especially.Wherein said phosphoric acid can substitute with the oxalic acid of 0.45～2.78 weight portion.
In step (C), be to immerse foam matrix in the pre-pattern under 18～22 ℃, through solidifying the demoulding behind the pre-type in 2～4 hours.
In step (D), described immersion liquid is with the fatty alcohol ethylene oxide condensate of 81～188 weight portions (commodity are called penetrating agent JFC), secondary octyl phenol polyethenoxy (10) ether (commodity are called emulsifier op-10) of 117～279 weight portions, the glycerine of 35～125 weight portions, the sulfuric acid amine of 543～1560 weight portions, the potassium dihydrogen phosphate of 235～966 weight portions, the carbonic hydroammonium of 186～1260 weight portions is mixed, the absolute ethyl alcohol that adds 165～120 weight portions then, join solution.Hybrid mode to each component is not particularly limited, and can mix under normal temperature or heating, as long as can use after fully mixing.In addition, the hexadecanol of also available 104～210 weight portions of described secondary octyl phenol polyethenoxy (10) ether substitutes.
In step (E), the size of section can be decided according to the actual requirements, and preferred slice thickness is the section of 1cm.
