Embodiment
With reference to the accompanying drawings, example of the present invention is described.Fig. 1 is the stereogram of root-proof water-supply cord of the present invention, but, this root-proof water-supply cord A surrounds the periphery of the capillary member 1 with capillary function all sidedly by the anti-root permeable part 2 with water penetration and anti-root (root of crop is not invaded) function, forms thin restiform bodies 3.As the capillary member 1 of this occasion, form by cloth, the nonwoven of synthetic or native fiber, have capillary function, according to such as, the title of trade name " ラ Block シ one ト " (manufacturing of ニ チ ア ス Co., Ltd.) is sold on market, thus, can use it.
On the other hand, since anti-root permeable part 2 also from the various commercially available products of spinning Co., Ltd. etc. such as Japan, so can use it.The polyester, polyethylene, the polyacrylic synthetic fibers that should anti-root permeable part 2 adopt as material, it is not invaded in the root of crop, still, form that water passed through 7 * 10
2～2 * 10
3μ m
2The fine holes of size, be woven or knitted into 0.2～3mm thickness.In addition, also can be cloth, nonwoven, the porous film of native fiber.
By anti-root permeable part 2, surround above capillary member 1, still,, consider following method here.Fig. 2 is one key diagram of expression manufacture method, it is following method, wherein, will be laid in according to the anti-root permeable part 2 of certain-length and width adjustment on platform etc., thereon, two ends at the width of preventing root permeable part 2, place according to the rules width and the capillary member 1 adjusted of thickness at the state of unnecessary 2a, 2b of residual regulation,, surround capillary member 1 inflection of unnecessary 2a, 2b, with overlapping between unnecessary 2a, the 2b, that this coincidence part is affixed.As affixed instantiation, be generally the bonding of bonding agent, the welding of heat.The bonding agent of this occasion, fusion temp can suitably be selected corresponding to material.
In addition, also can be sewing up of employing sewing thread.In addition, in the occasion that sews up, the gap of the spacing in sewing hole, sewing hole and sewing thread is necessary for the more tiny value with anti-root functionality, and still, this can be by after sewing up, and the mode of gap portion being stopped up by resin etc. solves.In addition, if the end of the length direction of anti-root permeable part 2 is more than needed, also that this part is affixed, then can cover capillary member 1 all sidedly by anti-root permeable part 2.Best, the thickness of the anti-root permeable part 2 of this occasion can obtain below the flexible 1mm.
If adopt above-mentioned manufacture method, then form the coincidence part form outstanding in the end of width (or length direction), its purpose is that affixed operation is easy, even there is this situation, on performance, without any problem still.Obviously, coincidence part can not stretched out in the end yet and carry out affixed.As another manufacture method, also can will prevent root permeable part 2 coilings according to the mode that is pre-formed coincidence part, make it be tubular, silk, cord are installed on capillary member 1, it is passed from anti-root permeable part 2 and strains, thus, capillary member 1 is drawn in the anti-root permeable part 2, though omit about the diagram of this point.If adopt this mode, then has the advantage that more easily forms coincidence part according to the mode of not exposing.
As the size of above thin restiform bodies 3, preferably width W is in the scope of 20～50mm, and thickness t is suitable value so that cultivate the occupied area of the basin of usefulness relatively in the scope of 2～6mm.This width W, thickness t according to the manufacturing of capillary member 1 and anti-root permeable part 2 before size adjusting, still, particularly with regard to thickness t, if adopt market sale product formerly, because its thinner thickness (2.5mm), thus can be one or according to many overlapping, form the thickness t of stipulating.Obviously, also can entrust manufacturer etc.,, be processed into the type of specific thickness t from first.
If it is the cultivation with tomato is an example, then, best from the viewpoint of rhizosphere restriction, the diameter of basin is in the scope of 15～20cm, and the degree of depth is in the scope of 20～30cm, thus, according to the thin restiform bodies 3 of above-mentioned size, only, provide suitable water stress in basin by 1 thin restiform bodies 3 is set.So, if size less than it, then quantity must increase, if greater than it, the glut of water then, this is not preferred.In addition, for length, according to the method described above, in long occasion, be difficult to make, 1m is the limit, if but be this degree, then be sufficient.In addition, because the cross sectional shape of thin restiform bodies 3 is definite by the cross sectional shape of capillary member 1, so, then form this shape if it is rectangle, circle, ellipse, polygon.Wherein, preferably adopt the type of above-mentioned flat rectangle (band shape), thereby the long-pending surface area of relative cross-section increases, water penetration is good, and carrying property is also good.
But, also can make the non-individual body of thin restiform bodies 3.Such as, adopt following method, wherein, send capillary member 1 and anti-root permeable part 2 continuously, during this period, by guide etc., the rounded and anti-root permeable part 2 of reeling, surround capillary member 1, with bonding between the end, welding or sew up, carry out it affixed.In addition, loom, the knitting machine that fabric, looped fabric can be formed cylinder is set around capillary member 1, transports capillary member 1, and around it, by loom, knitting machine, it all is not impossible that anti-root permeable part 2 is carried out woven, knitting method.If adopt this method, because thin restiform bodies 3 can form long strip type, so suitably be wound on the roller, in the process of circulation, the buyer can cut off ground according to suitable length and use it.
Fig. 3 is for adopting above root-proof water-supply cord A, and the key diagram of the occasion of rearing tomatoes by basin still, is put into ridging 5 in the basin 4 of above-mentioned size, until approaching surface, wherein, plantation tomato 6.In this occasion,,, offer the hole 7 of running through thin restiform bodies 3 according to the height of distance bottom surface 2～5cm in the side of basin 4.In addition, at the side-lower of basin 4, be equipped with the nutrient tank 9 of putting into nutrient solution 8, one end of thin restiform bodies 3 be impregnated in the nutrient solution 8,, on its extension line, extend to opposition side by hole 7 with carrying on the other end side direction top, from here, rise along tub wall, extend to the near surface of ridging 5.On the other hand, best, in terminal, a few thin restiform bodies 3 of reeling form ball 10.
Because top described,, grow and the result like this, can gather in the crops it so in tomato 6, will inhale on the nutrient solution 8 by thin restiform bodies 3.At this situation, because basin 4 is above-mentioned size, carry out the rhizosphere restriction, in vain nutrient is not turned back to the root place, taste is good.In addition, if thin restiform bodies 3 be above-mentioned size, then the size of basin 4 relatively provides appropriate water stress, and from this respect, taste is good.In addition, if make the end of thin restiform bodies 3 form ball 10, then from then on nutrient solution 8 is supplied with in the part concentrated area, infiltration equably in ridging 5.In this occasion, the root 6a of tomato 6 requires water, extends according to the mode that arrives thin restiform bodies 3, but, the anti-root permeable part 2 on the surface by thin restiform bodies 3 blocks, and does not invade capillary member 1 wherein, and the capillary function of thin restiform bodies 3 is not hindered.But, owing to tomato 6 is followed growth and is necessarily required more nutrient solution 8, so if many thin restiform bodies 3 are set in basin 4 in advance, corresponding to this growth, increase impregnated in radical in the nutrient solution 8, then can effectively cultivate.
According to this meaning, best, be arranged at the side of basin 4 by the hole 7 of thin restiform bodies 3.Its reason is: if be the bottom surface, then have the effect because of gravity, root 6a extends easily, the danger of 7 turnover from the hole.If root 6a is 7 turnover from the hole, then, enter into nutrient tank 9 according to the mode of in thin restiform bodies 3, transmitting, if like this, then form the water-cultivating that does not apply water stress, taste reduces.In this regard, if hole 7 is arranged at the side of basin 4, then root 6a is difficult to turnover.Equally in this occasion, it is little that ground must be done one's utmost in the gap of hole 7 and thin restiform bodies 3.
In addition, best, nutrient tank 9 and basin 4 leave according to certain degree.In addition, in the inside of basin 4, preferably also below thin restiform bodies 3, guarantee the ridging space a in the scope of 2～5cm.Its reason is: the root 6a that arrives thin restiform bodies 3 can be around going into this space a, in space, limited space (carrying out the root restriction), and in wide as far as possible scope, can be in great numbers equably, this also can form good taste.If thin restiform bodies 3 runs through the inside of basin 4 in such configuration, then tomato 6 obtains the good fruit of taste continuously between 10 months longer-term.Confirm through the inventor,, can grow to 25 joints near 1 year.
More than be an example of the present invention, still, the present invention is not limited to this.Such as, the size of root-proof water-supply cord is suitably adjusted in the growing process of crop.Specifically, in the summer that necessarily requires more water, it is effective using the big thin restiform bodies of sectional area.In addition, the crop of cultivating also is not limited to tomato, also can be muskmelon, other vegetables, fruit tree.In addition, nutrient tank and basin are not limited to 1: 1 relation, and nutrient tank also can be the such type of shared aqueduct.Basin also is not limited to other type, also can be the such type of continuous aqueduct.If like this, have the advantage that cost of equipment reduces.In addition, this root-proof water-supply cord is not limited to potted plant training, also is applicable to open-air cultivation.That is, if the root-proof water-supply cord is passed the ridge, then it forms water passage, promotes the growth of crop well.
