Description

TECHNICAL FIELD

[0001] The present application relates to the field of agriculture, in particular to a portable seedling raising agricultural film system for improving covering efficiency. BACKGROUND

[0002] At present, in order to keep warm and humidify, an agricultural film needs to be built around the seedbed when seedlings are raised, so as to form a suitable seedling growth environment. The traditional seedling raising agricultural film has many disadvantages in the application process, mainly in the following aspects:

[0003] Complex construction steps: the construction steps of the traditional agricultural film structure are complicated, involving various metal or bamboo parts such as arch beams, supports, etc., which need to be installed by professional technicians, and multiple people need to cooperate during installation.

[0004] Many materials and parts: the traditional agricultural film structure needs to use a large number of metal or bamboo parts and support structures, which not only increases the material cost, but also makes the construction and disassembly process complicated and time-consuming.

[0005] Difficult to disassemble: due to the complex structure, the traditional agricultural film has a huge workload of disassembly and re-construction when it needs to be moved or replaced, which is not conducive to quickly responding to market demand.

[0006] Transportation is not convenient: the traditional agricultural film structure has many limitations in the transportation process due to its large size and numerous parts during construction, which increases the logistics cost and time.

[0007] Easy to cause environmental pollution: the traditional agricultural film is usually made of disposable plastic film, which is usually discarded in the wild after use. With the large use of agricultural film, it is easy to cause "white pollution".

[0008] In addition, the current agricultural film system is in a closed state, and when it is hot, ventilation is needed. When ventilating, the ventilation opening of the agricultural film system needs to be opened manually, and after the temperature drops, the ventilation opening needs to be closed, so more labor cost needs to be invested in daily operation. SUMMARY

[0009] In view of the deficiencies in the prior art, the present application provides a portable seedling raising agricultural film system for improving covering efficiency and a use method thereof. The agricultural film system and the use method can realize rapid construction and disassembly of the agricultural film system, are more convenient during transfer and storage, use simple materials, can realize automatic ventilation and air permeation during use without additional labor investment, are low in cost, can realize recycling and reuse, and are ecological, environmentally friendly and pollution-free.

[0010] To achieve the above purpose, the technical scheme adopted by the present application is as follows: a portable seedling raising agricultural film system for improving covering efficiency, comprising:

[0011] Two water injection members arranged longitudinally, the water injection members having sealing structures at both ends;

[0012] A plurality of air injection members, including longitudinal air injection cylinders fixed on the two water injection members, a plurality of transverse air injection pipes connected with the longitudinal air injection cylinders, the transverse air injection pipes being arched after air injection, the two ends of the longitudinal air injection cylinders also having sealing structures;

[0013] An agricultural film used for covering, which is fixedly connected with the water injection members, and covers the air injection members;

[0014] Two self-rolling films, which are fixedly connected on both sides of the agricultural film, and include an agricultural film layer, on which a plurality of vertical fiber strips are arranged.

[0015] Further, the water injection members and the air injection members are made of agricultural film material.

[0016] Further, the water injection members are flat-cylinder-shaped after water injection, and are tightly attached to the ground.

[0017] Further, a plurality of fine pipes are arranged on the self-rolling film, and clean water is injected into the fine pipes.

[0018] Further, the inner surface of the agricultural film is tightly fixed on the air injection members or the water injection members.

[0019] Further, the two ends of the water injection members are tightly sealed by drawstring, and the longitudinal air injection channels of the air injection members are also tightly sealed by drawstring.

[0020] Further, at least one ventilation hole is arranged on the self-rolling film, a self-rolling curtain is connected on the top of the ventilation hole, and a plurality of fine pipes are connected on the bottom of the self-rolling curtain, and clean water is injected into the fine pipes.

[0021] The application also discloses a use method of the portable seedling raising agricultural film system for improving covering efficiency, which comprises the following steps:

[0022] S1: placing the water injection members and the air injection members on both sides of the seedbed respectively, injecting air into the air injection members to make them expand and form an arch-shaped air injection port, and supporting the agricultural film upward to form an arc after the air injection members expand;

[0023] S2: injecting clean water into the water injection port of the water injection member, tightly attaching the bottom of the water injection member to the ground after the water injection port is filled with clean water, and finally closing the water injection port;

[0024] S3: Injecting clean water into the thin pipe of the self-rolling film or self-rolling curtain, under the action of gravity, the clean water will deposit at the bottom of the thin pipe, increasing the weight of the bottom area of the self-rolling film or self-rolling curtain, in the normal temperature or low temperature state, the self-rolling curtain or self-rolling film is in the stretched state, in the high temperature state, the clean water in the thin pipe of the self-rolling film or self-rolling curtain will gradually evaporate to form water vapor, and move to the upper part of the thin pipe and adhere, so that the weight of the bottom of the self-rolling film or self-rolling curtain is reduced, due to the effect of thermal expansion and cold shrinkage, the self-rolling film or self-rolling curtain is rolled, so that the inside of the agricultural film system and the outside are connected, realizing ventilation and air permeation.

[0025] Compared with the prior art, the present application has the following beneficial effects:

[0026] 1. The agricultural film system and the use method can realize rapid erection and disassembly of the agricultural film system, greatly improve the agricultural film covering efficiency, and can realize automatic ventilation and air permeation according to temperature changes, reducing additional labor input;

[0027] 2. In the process of erection, only sufficient water is injected into the water injection member, which can fix the agricultural film, and after sufficient water is injected into the water injection member, the weathering speed of the water injection member can be effectively slowed down, and the service life thereof is increased;

[0028] 3. The air injection member is used instead of metal or bamboo arch beam, the cost is greatly reduced, and due to the counterweight effect of the water injection member, the strength is also sufficient. When disassembling, only the air in the air injection member and the clean water in the water injection member are exhausted, so that the folding and storage are facilitated, and the occupied space is smaller. Due to the convenience of erection and disassembly, the agricultural film system can be stored when not in use, effectively prolonging the service life and slowing down the aging speed, and can be reused to realize ecological environmental protection and pollution reduction.

[0029] 4. Since the self-rolling film is used, when the weather is hot, the water in the thin pipe will evaporate, the weight of the self-rolling film will decrease after evaporation, and the self-rolling can occur more smoothly, so that the whole system can ventilate and air permeate. When the weather temperature is suitable, the water in the thin pipe evaporates slowly, and under the action of gravity, the self-rolling film will naturally sag and stretch, so that the agricultural film system maintains a sealed state, promoting the heat and moisture preservation in the agricultural film system. In addition, the automatic rolling and sagging of the agricultural film are realized according to temperature changes, effectively reducing the additional labor input cost.

[0036] The technical solutions in the present application will be further described below in combination with the drawings and examples.

[0037] As Figures 1 to 5 shown in a convenient seedling raising agricultural film system for improving coverage efficiency, comprising:

[0038] Two longitudinally arranged water injection members 2, which are located on both sides of the seedbed when the agricultural film 1 system is built, the water injection members 2 have sealing structures at both ends, which can quickly seal the water injection members 2 after water injection to prevent clear water from leaking;

[0039] A plurality of air injection members, including longitudinal air injection cylinders fixed on the two water injection members 2, wherein the longitudinal air injection cylinders can be bonded to the water injection members 2, a plurality of transverse air injection pipes in communication with the longitudinal air injection cylinders are connected between the longitudinal air injection cylinders, the transverse air injection pipes are arched after air injection, and the two ends of the longitudinal air duct 7 also have sealing structures;

[0040] An agricultural film 1 for covering, which is fixedly connected with the water injection member 2, and the fixing mode can be bonding, the agricultural film 1 covers above the air injection member;

[0041] Two self-winding films 4, which are fixedly connected on both sides of the agricultural film 1, the self-winding film 4 includes an agricultural film layer, and a plurality of vertical fiber strips 6 are arranged on the agricultural film layer.

[0042] The application is used, first, the seedbed is placed on both sides of the water injection member 2, the water injection member 2 is made of agricultural film material, in order to enhance its strength, its thickness is 2-3 times of the general agricultural film, PVC material or rubber material like inflatable swim ring can also be used, which is convenient to fold and store, the length of the water injection member 2 matches the length of the seedbed, first, water is injected into the water injection member 2, after the water is injected, the water injection port is closed, then gas is injected into the gas injection member, so that the gas injection member is expanded and formed, after the gas injection member is expanded and formed, the agricultural film 1 is lifted and covers above the water injection member 2, wherein the agricultural film 1 can be connected with the water injection member 2 through the two side edges, such as fixed by strong glue. The system, when the weather is hot, due to the different thermal expansion coefficients of the fiber strip and the agricultural film layer of the self-winding film, the thermal expansion coefficient of the fiber strip is larger, if the fiber strip expands at high temperature, it will expand along the length direction (vertically upward), at this time, it will generate an upward pulling force on the outer bottom of the agricultural film, this upward pulling force will make the bottom of the agricultural film have a tendency to move outward, finally make the bottom of the agricultural film roll outward and form a roll part, so the self-winding film 4 can be wound and keep a certain distance from the ground, so as to realize the ventilation of the whole agricultural film 1 system, when the temperature is suitable (such as at night), it can be stretched, keep the sealing state of the system and realize the heat preservation and moisture retention. Through the above structure of the agricultural film 1 system, the whole agricultural film 1 system can be quickly prepared, after preparation, it can realize rapid transportation and installation, the erection efficiency can also be greatly improved, and the operation is simple, the technical requirement of the operator is less, and the popularization and application are realized. The agricultural film 1 system has good environmental adaptability, because the agricultural film 1 is supported by the gas injection member, the gas injection member is in a flexible state as a whole, and has good ductility, so even in windy weather, the agricultural film 1 and the gas injection member as a whole will deform, after the wind stops, the agricultural film 1 and the gas injection member will return to the original state, while the traditional agricultural film is covered on the rigid member, which is easy to be damaged when encountering strong wind.

[0043] Further, the water injection member 2 is in a flat cylinder shape after water injection and is tightly attached to the ground. Specifically, the water injection member 2 is in a flat cylinder shape after water injection and is tightly attached to the ground, so that its expansion degree is kept at a low level, and it has ductility and is not easy to be damaged under external force.

[0044] Further, the self-rolling film 4 is provided with a plurality of thin pipes 5, and the thin pipes 5 are filled with clean water. By arranging the thin pipes 5 and filling the thin pipes 5 with clean water, the bottom of the self-rolling film 4 has a large weight. When the air temperature rises, the clean water in the thin pipes 5 evaporates upward, and the water vapor or water droplets condensed from the water vapor are located at the upper part of the thin pipes 5. The amount of clean water at the bottom of the thin pipes 5 is reduced, and the weight of the self-rolling film 4 is greatly reduced. At this time, the self-rolling film 4 is better rolled due to the fiber strips 6 on the self-rolling film 4 and the thermal expansion and contraction effect. When the air temperature is low, the evaporation amount is reduced, and a large amount of clean water is accumulated at the bottom of the thin pipes 5, so that the self-rolling film 4 is better stretched.

[0045] Further, the inner surface of the agricultural film 1 is tightly fixed on the air injection member or the water injection member 2. Specifically, the agricultural film 1 of the present application is pasted on the air injection member or the water injection member 2 through the inner surfaces of the two sides of the agricultural film 1. In this way, the assembly of the agricultural film 1 is more convenient.

[0046] Further, the two ends of the water injection member 2 are tightly sealed by the drawstring 8, and the longitudinal air duct 7 of the air injection member is also tightly sealed by the drawstring 8. Specifically, the water injection member 2 of the present application can be open at both ends or open at one end. When the water injection member 2 is open at both ends, one end is first tightly sealed by the drawstring 8, and then the other end is filled with water. After the water injection is completed, the other end is tightly sealed. In addition, the air injection member can also be open at both ends or open at one end. When the air injection member is open at both ends, one end is first tightly sealed by the drawstring 8, and then the other end is filled with air. Since the longitudinal air duct 7 is in communication with the transverse air duct 3, the air injected from the longitudinal air duct 7 will fill the transverse air duct 3 and the other longitudinal air duct 7. After the air injection is completed, the other end is tightly sealed.

[0047] The present application also includes a method for using a portable seedling raising agricultural film 1 system to improve the covering efficiency, which comprises the following steps:

[0048] S1: placing the water injection member and the air injection member on the two sides of the seedbed, respectively, and injecting air into the air injection member to make the air injection member expand and form an arch-shaped structure, and then sealing the air injection port. After the air injection member expands, the agricultural film on the air injection member is lifted upward and forms an arc shape;

[0049] S2: filling the water injection port of the water injection member with clean water. After the water injection port is filled with clean water, the bottom of the water injection member is in contact with the ground, and finally the water injection port is sealed.

[0050] S3: in the self-rolled film 4 or the thin tube 5 of the self-rolled curtain, inject clean water, under the action of gravity, the clean water will deposit at the bottom of the thin tube 5, increase the weight of the bottom area of the self-rolled film 4 or the self-rolled curtain, in the normal temperature or low temperature state, the self-rolled curtain or the self-rolled film 4 is in the relaxed state, in the high temperature state, the clean water in the thin tube 5 of the self-rolled film 4 or the self-rolled curtain gradually evaporates to form water vapor, and moves to the upper part of the thin tube 5 and adheres, so that the weight of the bottom of the self-rolled film 4 or the self-rolled curtain is reduced, due to the effect of thermal expansion and cold shrinkage, the self-rolled film 4 or the self-rolled curtain is self-rolled, so that the inside of the agricultural film system and the outside are connected, and ventilation is realized.

[0051] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
