Description

TECHNICAL FIELD

[0001] The seed-carrying composite drip irrigation belt and its manufacturing method are suitable for the field of agricultural drip irrigation belt production. BACKGROUND

[0002] Water-saving drip irrigation has become a mainstream means of agricultural water saving. Research has found that the more accurate the dripper (water outlet point) of drip irrigation is close to the main root system of crops, the higher the utilization rate of water and fertilizer is, that is, more water-saving and fertilizer-saving. However, it is difficult for our existing agricultural machinery to accurately position the drip irrigation belt and the seeding point, thus causing a low utilization rate of water and fertilizer. At the same time, during the seed germination period, the water point is very small, and the soil humidity requirement is very high. Excessive water will cause land compaction, and seedlings cannot emerge; and insufficient water will cause seed germination difficulty due to water shortage. At this time, the position of the dripper of the field drip irrigation belt is inconsistent with that of the seed, which will exacerbate the uneven irrigation during the seedling emergence process, thus seriously affecting the seedling emergence rate and hindering the improvement of crop yield.

[0003] On the other hand, the primary condition for high yield of agricultural crops is the seedling emergence rate. In order to ensure the seedling emergence rate, in addition to selecting excellent varieties, the main indexes such as seeding uniformity, seeding uniformity, hole seed number, plant spacing, and seed damage rate need to reach the standard. However, these indexes mainly depend on the on-site operation of the seeding machine to ensure, and due to the inconsistency of different machines and manual adjustment, it is difficult to actually reach the indexes, and the consistency is poor. This has an impact on the seedling emergence rate and the later growth. Therefore, the usual practice is to increase the seeding amount of seeds. However, this not only causes waste of seeds, but also increases the workload of seedling care in the later period, affects the yield, and also increases the cost of agricultural planting. How to achieve seeding uniformity, seeding uniformity, accurate and uniform plant spacing, accurate hole seed number, and reduce seed damage rate has been a difficult problem in the research and development and manufacturing of agricultural field machinery in China. SUMMARY

[0004] In order to solve the above problems, we propose this innovative application, the purpose of which is to provide a seed-carrying composite drip irrigation belt; another purpose based on the above purpose is to provide a manufacturing method of the seed-carrying composite drip irrigation belt.

[0005] The purpose of the present application is achieved as follows: a strip-shaped base belt is used as a carrier, the drip irrigation belt and the dripper are integrated with the base belt in the direction of the base belt, and the seeds are attached to the base belt. The base belt is integrated with the drip irrigation belt or is separately provided, and the dripper is communicated with the drip irrigation belt.

[0006] The strip-seeded crop seeds are distributed in a strip shape on the base belt, the base belt, the drip irrigation belt, and the seeds are distributed in parallel, and the distance between the dripper and the seeds should be less than 10 cm.

[0007] The seeds of the hill-planting crops are distributed in the form of holes on the base strip according to the required plant spacing, and 1-4 drippers are arranged around each hole. The drippers are distributed within the root system of the adult plants of the planted crops to ensure that the water discharged from the drippers can be absorbed by the crops to the maximum extent.

[0008] Fertilizer bags can also be attached to the base strip at the same time, and the fertilizer bags contain any one or both of the fertilizer and the pesticide. The fertilizer bags are wrapped with film or mesh material and attached to the lower surface of the base strip, and the position of the fertilizer bags should be closer to the drippers than the seeds. In this way, the seeds can be prevented from being burned by direct contact with the fertilizer and the pesticide, and the fertilizer and the pesticide can be better dissolved before being absorbed by the root system of the crops.

[0009] In order to ensure that the seeds can obtain sufficient water for germination, the best way is to place 1-2 drippers within a range of 5 cm from the seeds of the hill-planting crops and place the remaining drippers outside the range of 5 cm from the seeds; and the best direction of the water outlet of the dripper is downward or horizontal. In this way, the water required for the germination of the seeds can be ensured, and the root system of the adult plants can be effectively covered.

[0010] The reasonable layout is that one side of the base strip is a tubular drip irrigation belt, and the other side of the base strip is a seed fixing edge. Alternatively, a tubular drip irrigation belt is arranged in the middle of the base strip, and seeds are fixed on both sides of the base strip. A fertilizer bag can be arranged between the seeds and the drip irrigation belt of the base strip. The drippers are attached to the surface of the base strip to which the fertilizer bag is attached, and the water outlet of the dripper is arranged in the fertilizer bag.

[0011] In order to realize the above-mentioned seed-carrying composite drip irrigation belt, the following method is adopted: the seeds, the drip irrigation belt and the base strip are combined into one body to form a belt-shaped body. One of the combination methods of the drip irrigation belt and the base strip is that the base strip and the drip irrigation belt are formed by plastic processing at one time, and then the seeds and the fertilizer are attached to the base strip. There are two seed attachment methods: one is to wrap the seeds with a film to make seed bags, and then to attach the seed bags to the base strip by the attachment method. The other is to manufacture a series of through holes in the strip-shaped area of the base strip in the direction of the base strip in advance, then to attach the film on both sides to form seed bags, and to place the crop seeds in the seed bags.

[0012] The film mentioned in the foregoing description is a film-shaped or mesh-shaped material with a certain strength; the film has the characteristics of deliquescence or water solubility; and the film can be made of water-soluble material or paper material.

[0013] By means of the above-mentioned seed-carrying composite drip irrigation belt and the manufacturing method thereof, the structure of the seeding machine can be simplified, and the field operation difficulty can be reduced. The seeds, the fertilizer and the drip irrigation belt are laid in precise position in one body, and this high-precision positioning method ensures the precise delivery of water and fertilizer, greatly improves the germination rate of the seeds and the yield of the crops. Therefore, the seeds, the fertilizer and the irrigation water can be saved while the yield of the crops is improved, and the technical and popularization requirements of fine agriculture are fully met.

[0020] Example: Figure 1 As shown, crop seeds are fixed along a strip of base tape with drip irrigation tape. The drip irrigation tape and drippers are installed on the base tape, which has a tubular structure.

[0021] A reasonable layout is to have the drip irrigation tape, dripper, and seeds arranged in sequence on the horizontal surface of the base. If fertilizer packs are needed, it is best to place them between the seeds and the drip irrigation tapes.

[0022] like Figure 2 As shown, the seeds of row-sown crops are distributed in strips on the base strip. The base strip, drip irrigation tape and seed strips are parallel, and the dripper should be less than 10 cm away from the seed strip.

[0023] like Figure 3 As shown, seeds for hill-sown crops are distributed in holes according to the required spacing. The optimal method is to place 1-4 drippers around each hole. The drippers should be placed within the root system of the mature crop plant. Place 1-2 drippers near the planting hole and the remaining drippers at a relatively distant location. The dripper openings should be downward or horizontal.

[0024] Fertilizer packs consist of a film or plastic film mesh that wraps the fertilizers and pesticides needed by the crop and is attached to the lower surface of the base.

[0025] Drip emitters should be installed on the substrate surface to which the fertilizer pack is attached, and the drip emitter outlet should be close to or located inside the fertilizer pack.

[0026] To achieve the aforementioned seed-carrying composite drip irrigation tape, it will be manufactured as follows: seeds, drip irrigation tape, and base tape will be combined into a single strip. Drip emitters will be placed at appropriate locations on the base tape, connecting them to the drip irrigation tape.

[0027] The best method example that can be implemented is achieved in the following two-step manner:

[0028] First step: the base band and drip irrigation tape are integrally formed by plastic processing;

[0029] Second step: the seeds are attached to the base band.

[0030] Another embodiment can also be implemented:

[0031] First step: the drip irrigation tape is independently processed and formed

[0032] Second step: the seeds and drip irrigation tape are simultaneously or sequentially integrated with the base band.

[0033] The method for fixing and attaching the seeds and the base band can be implemented in two ways:

[0034] First: as shown in Figure 4 The seeds are first wrapped with a film to make seed packets; then the seed packets are attached and fixed to the base band to form a whole.

[0035] Second: as shown in Figure 5 A series of through holes are pre-manufactured on the base band along the base band strip-shaped area; then a film is attached on one side, the crop seeds are placed on the attached film, and a layer of film is covered on the other side of the base band, wrapping the seeds between the two layers of film, thereby making seed packets on the base band.

[0036] The fertilizer packet attachment method is to wrap the required fertilizer and pesticide of crops with a film to form a fertilizer packet, which is then attached to the lower surface of the base band.

[0037] The above-mentioned attachment methods can be hot pressing and gluing, etc.

[0038] The above technical features constitute the best embodiment of the present application, which has strong adaptability and optimal implementation effect. Non-essential technical features can be added or subtracted according to actual needs to meet the needs of different situations.
