Description

Support member especially for the crop growth on the roof of planting plants
Technical field
The present invention relates generally to the support member for the crop growth on the roof of planting plants.
Background technology
Because many reasons is requiring to develop natural prodcuts now.We know, for example in building, limit waste and the possibility of regulating internal temperature are to consider the roof of planting plants.Certainly, this only is an example, and we can find other extensive application on industrial building, in these industrial buildings, the temperature difference should be restricted, and also can be the application in interior, in order to guarantee the surface that air or permeability are controlled is processed.
In the situation on the roof of planting plants, no matter outside cold or hot, crops are all guaranteed heat insulation, have so also just reduced the energy consumption that is used in the winter time heating, and are used for the energy consumption of freezing or cooling off at least in summer.
This Plants increases the thermal inertia of building.
Plant is placed on the roof of its surface with sealant, and sealant is made of inert complexes usually, and plant can not be planted on the compound, and can not slowly grow.
The effect of sealing layer only is the sealing of guaranteeing in some way the roof, in order to prevent any infiltration.
Plant is the plant of planting very weather variation and Anti-temperature difference, for example known in this application " red-spotted stonecrop " kind.
Layer of plants comprises the matrix that is made of thin soil layer and rice shoot, and this soil layer utilizes the air channel that combines with soil to fix usually, and rice shoot itself is made of the foundation of making somebody a mere figurehead part and prick in soil and air channel.This layer of plants stands the precipitation with climatic variation, thereby must be able to regulate precipitation and carry out draining, in order to prevent because of rotting that water causes too greatly, and can also distribute irrigation when precipitation greatly reduces, in order to prevent a large amount of arids of plant or dead.
A known solution is to settle a crops support member, and layer of plants is placed on the crops support member.
Particularly, the theme of this crops support member European patent EP 2227080 that is the applicant.
This crops support member is made of vegetable fiber, and in this case, according to a pattern very preferably, fiber is hemp preferably.These fibers twine by colligation usually.
This crops support member is for the compatibility of itself and plant, and is particularly highly beneficial with the compatibility of plant establishment.
In order to carry out controlled pouring in very dry season, just be necessary for water on the plant.A known scheme is that the pipe network that waters is combined with this crops support member.European patent EP 2227080 proposes this pipe network, and exactly the pipe network of commercial Application is fixed on the crops support member.
This scheme is to arrange the first fibrage, arranges pipe network, and the enhancement layer that also wove the first fibrage setting thus on pipe network is settled the second fibrage, and guarantees first and second layers of colligation between each pipe.
In case enhancement layer is fettered, this enhancement layer just is between these two fibrages, guarantees that thus respectively pipe is fixed along pipe network of determining.
Some holes are arranged on these pipes, drop by drop water in order to guarantee.
Yet, also having some still unsatisfied additional requirements, one of them is to be diffused in the crops support member pouring water from watering of pipe, another stops water exactly during taking root.
In fact, irrigating integrated net can not be by leaning on to such an extent that too near pipe consists of each other, and this might cause each pipe very long, therefore causes cost to increase.In addition, the water that provides from each hole probably has one one still to divide vertical with described hole.Described soil guarantees to carry out diffusion ideally, and still, we know that this diffusion is always very slow.In addition, diffusion can not be improved in the air channel of existing enhancement layer, can not make the water distribution of realizing ideal.
The present invention is intended to overcome these problems.
In addition, we also know, several centimetres crooked air channel can produce hitch point crosswise usually, and this is because the crops support member rolls the cause of rolling up and scattering on the spot manufacturing after.
For Second Problem, its cause is that requirement remains on water in the crops support member abundantly, remain in the matrix thus, thus the rice shoot that during taking root, can be conducive to plant at least take root, these rice shoots are to be provided on the described support member with their matrix.In fact, when arid season waters, must keep enough moisture in the bottom of plantation layer, in order to the rice shoot that provides is fixed on the support member.
Certainly, solution is to water better, but environmental benefit and economic interests will be greatly affected.
Otherwise, then can confirm, because following reason needs the delay of restriction water: the rice shoot of having taken root is arranged necessary drainage mechanism.
The present invention is intended to overcome this two problems.

Embodiment
Fig. 1 shows the crops support member 10 for receiving crops matrix 12 of the present invention, and crops matrix 12 itself is used for receiving rice shoot 14.
It mainly uses the Plants that basically remains on the roof, but the present invention also be suitable for utilizing support member of the present invention all be equal to application.
Support member of the present invention comprises the first braid 16 that is called the bottom, and irrigation pipe 18 is arranged on the first braid 16.
This first braid 16 is made of the fiber of material of vegetable origin, for example hemp.By colligation these fibers are carried out combing, in order to make braid have mechanical strength.
Unshowned supply barrel at least one side in pipe 18 and the many sides is connected, and supply barrel is known.
These pipes 18 are that the water that makes with a plurality of dispensing orifices drop by drop flows out the pipe of formula, and described hole evenly arranges along length as required.These holes are flute profile preferably, so that the obstruction that restriction may cause because of the sedimental accumulation of various solubilized and material that can crystallization.In fact, these grooves can more or less " allow " pressure expansion and variation according to temperature, and therefore, sediments no longer condenses, and groove can not stop up yet.
In addition, the cross section of pipe 18 is preferably oval, in order to keep maximum cross section under limited height.
Therefore, these pipes 18 are arranged on the first braid 16 of bottom.Proper is to fix these pipes, according to the present invention, has a maintenance and diffusion braid 20, and this braid 20 is stacked on the first braid 16, and passes through on pipe 18.
This maintenance braid 20 is preferably an act formula, and the weight that is to say unit are is limited, for example 60g/m 2According to following needs, can select to make this curtain 20 with different materials.
In fact, fully can be biodegradable if support member must be made, then proper is to select in biodegradable synthetic fibers, just as polycaprolactone, is called PLA.In these cases, after for example finishing in 3 years preset time, fiber disappears.In this case, rice shoot can be taken root, because root is staggered, and utilizes matrix itself, will maintain well pipe, and pipe fixedly is in the matrix.
If do not need biological degradability fully, and if must make the machinery of pipe keep permanent, then film can adopt synthetic fibers, for example polypropylene.
In any case, be the fiber of regulating and diffusion braid 20 is selected, particularly no matter this fiber weave or non-woven, it all should pass through well diversion of capillarity, in order to will from the water of the pipe whole surface diffusion to support member, be diffused into thus all lower surfaces of crops support member.
Preferably be provided with second braid 22 that is called the surface, this braid is between the pipe 18 by band, and is on adjusting and the diffusion braid 20.This surface weave layer 22 guarantees to replenish thickness, and holds onto adjusting and diffusion braid 20.
In order to have firm support member, preferably with the braid 16 of these two vegetable fibers and 22 combings between each pipe, thereby need not punch for them.
This combing by colligation can will regulate with the method for machinery simultaneously and diffusion braid 20 is strapped between two braids 16 and 22, and pipe 18 is maintained static, and this can't damage its distribution capability.
Like this, not only kept pipe, but also will be from the water of pipe effectively towards the surface diffusion of support member.
In addition, above-mentioned another problem is taking root of rice shoot, thereby not only diffusion will be regulated evenly, and to keep enough amounts, can not increase thus the water yield of watering, because the water yield of watering must keep minimum as far as possible, so that not to ecological balance injury.
In addition, can exist or not exist diffusion to keep curtain, can be in the bottom lower surface of the first braid 16 be provided with and regulate film 24.
Therefore, this of setting regulated film 24 and the support member that is used for receiving plant, and normally seal protection layer is relative.
By any suitable mode, particularly in the fiber combing, will regulate film 24 be attached to the bottom braid 16 lower surface on.
This adjusting film 24 preferably has and allows the film of the micropore that air passes through, thereby blow-by so just stops for flowing or blow over and cover completely the complete oxygen supply of taking root in water.
This purpose is to stop water, do not allow water too soon by matrix when watering, and immature rice shoot does not also enough take root to bear confined watering, and contains very large heat in the water that waters.
This film can guarantee horizontal diffusion especially, because we know, in immature matrix, is formed with preferential discharge tube, and these pipelines are so that infiltration is too fast, maldistribution.
Certainly, regulate and the diffusion braid in the situation that have, because the first horizontal diffusion is arranged, this phenomenon disappears, but this phenomenon not have because there is this adjustings film 24 to aggravate in the situation of adjusting and diffusion braid, regulates film 24 at this moment and has booster action.
For the category that obtains wishing, the quantity in hole is every square centimeter of 6 holes, the hole that these holes preferably utilize teasing needle to make in colligation operating period.
On the contrary, we also know and are crossing seedling growth after the phase, and it is very little that the effect of this adjusting film 24 just becomes.In fact, the density of matrix increases, and the number of root is a lot, even in the situation that the shorter rice shoot leaf of red-spotted stonecrop has also covered matrix, and still can stop more natural rainfall or from the water of pouring.
In addition, can confirm that it is very desirable by the natural biological degraded film being disappeared.The film that has micropore can be selected from for example material of known polycaprolactone PLA, or is selected from other from any material of plant, for example take the film of plant powder as base, their biological degradation time even can change as required.
Biological degradation is carried out in given time limit, and the variation of infiltration is gradually, and the growth of this and root is well matched.We see, the support member of crop growth of the present invention is many performances, has particularly covered the advantage of existing growth support member, mainly are the advantages of the support member that proposes of same holder.
Like this, can be with these support members with the pipe scrolling that waters of incorporating into, in order to easily they are placed the roof; This has just limited volume, keeps their hydrodynamic(al) ability for these pipes, and machinery is kept not infringement, also can not cause adjusting and diffusion braid to hang and infringement.
Note also that, this growth support member can be made, and can very large change not arranged to existing machinery, and therefore, manufacturing cost is also compatible with more and more stronger these products of diffusion.
