Detailed Description
The following description and the specific embodiments are made with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
Referring to fig. 1 and 2, the drip irrigation system described in the present embodiment includes at least one drip irrigation header 100 and a main pipe 101 connected to the drip irrigation header, and a drip irrigation tape 200 is connected to the main pipe 101. In some embodiments, the drip irrigation system includes a set of drip irrigation headers 100 and a main pipe 101 connected to the drip irrigation headers. In other embodiments, the drip irrigation system includes two sets of drip irrigation headers 100, each set of drip irrigation headers externally connected to a main pipe 101, the two main pipes respectively communicating with different flow passages in the composite drip irrigation tape. Fig. 1 and 2 only show one set of drip irrigation header 100 and one main pipe 101.
Referring to fig. 3, the drip irrigation tape 200 is formed by overlapping and connecting the edges of the films along the length direction, and in this embodiment, the drip irrigation tape 200 is formed by overlapping and connecting the edges of the first film 201 and the second film 202 along the length direction in a staggered manner. As shown in fig. 3, the first film 201 and the second film 202 are connected in an interlaced manner at the upper portion thereof to form a first connecting film 203, and the first film 201 and the second film 202 are connected in an interlaced manner at the lower portion thereof to form a second connecting film 203', so that the first film 201 and the second film 202 are not folded when the drip irrigation tape 200 is in an expanded state, thereby preventing the connecting portion from being torn.
Referring to fig. 4, the film overlapping portion is provided with a drip irrigation flow path 2031, the first connection film 203 and the second connection film 203' are both double-layered films, and the drip irrigation flow path 2031 is provided in the middle of the double-layered films so that liquid in the drip irrigation tape 200, such as water, a solution in which a water-soluble fertilizer is dissolved, or a solution in which a pesticide is dissolved, slowly permeates out of the drip irrigation flow path 2031. The drip irrigation flow channel 2031 is provided as a labyrinth flow channel, which can slow down the speed of drip irrigation. Meanwhile, the drip irrigation flow channel 2031 is arranged at the overlapping part of the first film 201 and the second film 202, and during drip irrigation, the hydraulic pressure of the drip irrigation tape acts on the drip irrigation flow channel 2031 to further inhibit the drip irrigation runoff and make the drip irrigation more uniform. The drip irrigation flow path 2031 is printed on the first film 201 or/and the second film 202 by embossing, or a middle film is disposed between the first film 201 and the second film 202, and the drip irrigation flow path 2031 is printed on the middle film by embossing, and both surfaces of the middle film are connected to the first film 201 and the second film 202, respectively.
Certainly, when drip irrigation is carried out, attention needs to be paid to whether the water-soluble fertilizer and the pesticide have mutual negative effects or not, namely when part of the fertilizer and the pesticide are mixed, ammonia volatilization, precipitation or compound decomposition are easily generated. For example, alkaline pesticides such as Bordeaux mixture, lime sulphur mixture, rosin mixture and the like cannot be mixed with ammonium nitrogen fertilizers such as ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride and the like or calcium superphosphate, otherwise ammonia volatilization or precipitation is easily generated, so that the fertilizer efficiency is reduced; alkaline fertilizers such as ammonia water, lime and plant ash cannot be mixed with pesticides such as trichlorfon and dimethoate, and most organophosphorus pesticides are easy to decompose and lose efficacy under alkaline conditions; the chemical fertilizer cannot be mixed with microbial pesticides, and because the chemical fertilizer is high in volatility and corrosivity, if the chemical fertilizer is mixed with the microbial pesticides such as bacillus borer killing bacteria and green worm bacteria, microorganisms are easy to kill, and the prevention and treatment effect is reduced; the arsenic-containing agricultural chemicals cannot be used in combination with potassium salts, sodium salts, etc., and for example, calcium arsenate, aluminum arsenate, etc. when mixed with potassium salts, sodium salts, etc., soluble arsenic is produced, causing phytotoxicity. Therefore, during drip irrigation, attention is paid to flushing of the pipeline, and direct drip irrigation of pesticide under the condition that the fertilizer remains in the drip irrigation tape or direct drip irrigation of the fertilizer under the condition that the pesticide remains in the drip irrigation tape is avoided. Of course, because the drip irrigation flow passage on the drip irrigation tape has a low drip speed and the time for flushing the pipe is long, in view of this, in a further embodiment of the present invention, an embodiment is provided in which the fertilizer and the pesticide are separately drip-irrigated.
In a further embodiment, with reference to fig. 5 to 7, said drip irrigation tape 200 comprises a non-return tape; the non-return belt is connected with the drip irrigation belt or is arranged in one or more sections of the drip irrigation belt. The non-return belt is formed by overlapping and connecting three film belts along the edge of the length direction in a staggered manner, wherein the three film belts are respectively a first film 201, a second film 202 and a non-return film 204. A pair of parallel edges of the non-return film 204 is clamped between the two film strips; one side of the other pair of parallel edges of the non-return film is connected with one film belt, and the other side of the non-return film is connected with the other film belt. Specifically, in the front view of fig. 7, the check film 204 is a rectangular plastic film, the check film 204 is provided with a first connecting portion 2041, a second connecting portion 2042, a third connecting portion 2043 and a fourth connecting portion 2044 at the upper, lower, left and right sides thereof, respectively, the check film 204 is provided with two fourth connecting portions 2044 at the lower side thereof, and the number of the fourth connecting portions 2044 can be adjusted. The second connecting portion 2042 is disposed in the middle of the first connecting film 203, the third connecting portion 2043 is disposed in the middle of the second connecting film 203', the first connecting portion 2041 is connected to the first film 201 by a surface or a line, and the fourth connecting portion 2044 is connected to the second film 202 by a point. The length of the non-return film 204 is 2-4 times, preferably 4 times of the inner diameter of the drip irrigation tape. Referring to fig. 6, the fluid L flows from the first connecting portion to the fourth connecting portion of the non-return film 204, and the fourth connecting portion 2044 is connected to the second film 202, so that a unidirectional flow channel is formed between the fourth connecting portion 2044 and the second film 202 for the fluid to flow together, the opening of the unidirectional flow channel is smaller than the inner diameter of the drip irrigation tape under the pulling force of the fourth connecting portion 2044, and the size of the opening of the unidirectional flow channel is related to the number of the fourth connecting portions 2044. If the fluid flows back, the fluid applies a pressure F to the check membrane 204 to make the check membrane 204 and the second membrane 202 adhere to each other, so that the fluid cannot flow back. It is obvious that the fluid flows downwards only under the action of gravity, and in this case, the fluid does not flow back, but this does not solve the problem of uneven drip irrigation in different height areas of the same dropper system. Therefore, in order to make the drip irrigation of the land areas with different heights in the same drip irrigation system uniform, the drip irrigation header is arranged at the lowest point of the drip irrigation area, and the fluid flows from the lower part to the higher part under the action of the header. The head stops working and the fluid flows back under the action of gravity, at which point the non-return membrane 204 acts to prevent the fluid from flowing back. Referring to fig. 1 and 2, two different land parcels are shown, wherein the low-level land parcel is a relatively flat land parcel, and the drip irrigation tape on the land parcel only needs to be provided with a section of non-return tape at the joint of a main pipeline; the high-position land is an inclined land with a high position and a low position, each drip irrigation tape is arranged according to the contour line direction, and a section of non-return tape is arranged at the joint of each drip irrigation tape and the main pipeline.
In another embodiment, the drip irrigation tape 200 is formed by overlapping and connecting two film strips along the longitudinal edges, and one of the two films is a mulching film. Referring to fig. 8, the first film 201 is disposed under the second film 202, and the second film 202 extends to both sides as a mulching film. Fig. 8 shows the situation where two drip irrigation tapes share the same second membrane 202. One of the two drip irrigation belts is connected with the main pipeline connected with the fertilizer drip irrigation header, the other drip irrigation belt is connected with the main pipeline connected with the pesticide drip irrigation header, and any one of the two drip irrigation belts can be used for drip irrigation of water. Further, a planting hole 2021 is provided in the second film 202, i.e., the mulching film, between the two drip irrigation tapes. In this embodiment, a non-return film may be provided in the drip irrigation tape, but it is of course possible to select a non-return tape for connecting the drip irrigation tape to the main pipe.
In yet another embodiment, referring to fig. 9, there are two drip irrigation headers, each of which is connected with a main pipe, the drip irrigation tape is a composite drip irrigation tape, the long side of the a side of the composite drip irrigation tape film 2101 is a third connecting film 2103, the long side of the B side is a fourth connecting film 2103 ', the third connecting film 2103 is connected with the middle of the a side to form a first flow channel 211, and the fourth connecting film 2103' is connected with the middle of the B side to form a second flow channel 212; the main pipe to which the two drip headers are connected is connected with the first flow channel 211 and the second flow channel 212, respectively. Preferably, the main pipes to which the two drip headers are connected with the first flow passage 211 and the second flow passage 212, respectively, through non-return bands.
In a further embodiment, referring to fig. 10, the third tie film 2103 extends in the width direction of the film to form a first wing film 2101 ', the fourth tie film 2103' is attached to a second wing film 2102, the second wing film 2102 is attached to the B-face middle; the connection part of the fourth connection film 2103' and the second wing film 2102 is provided with a drip irrigation flow channel. The first wing film 2101' and the second wing film 2102 constitute a ground film.
