Description

Technical Field

[0001] This invention belongs to the technical field of three-dimensional ecological agricultural farming model, specifically a sugarcane-fish symbiotic ecological farming method. Background Technology

[0002] Although sugarcane is a dry-season crop, its profitability largely depends on the availability of irrigation. Currently, sugarcane yield is low, only about 4 tons per unit area. At a price of 500 yuan per ton, the output value per mu (approximately 0.16 acres) is 2000 yuan, and the profit per mu after deducting costs is only about 800 yuan. In recent years, sugarcane planting enterprises (large-scale growers) and research institutions have been continuously exploring integrated water and fertilizer management to improve the efficiency of sugarcane cultivation. How to better utilize water resources is particularly important.

[0003] The sugarcane-fish symbiotic farming technology is a new ecological farming model and a new way to develop organic and efficient agriculture. Therefore, based on the growth characteristics of sugarcane and the growth and development patterns of fish, developing a standardized and reasonable sugarcane-fish symbiotic ecological farming method can not only increase sugarcane yield but also increase the extra income of sugarcane farmers, thereby achieving higher economic benefits. This has important significance and application value. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) This invention increases sugarcane yield, reduces fertilizer usage, and lowers planting costs by making reasonable use of water resources. The average yield of sugarcane per mu is increased from 4.5 tons to 6 tons, while reducing fertilizer usage by 30%.

[0023] (2) This invention can also achieve the dual benefits of "one water for two uses and one field for two harvests" through "sugarcane-fish symbiosis", realize the goal of "fish and sugarcane win-win", increase sugarcane farmers' income, and produce 1.18 tons of commercial fish per pond per year, with an output value of more than 20,000 yuan.

[0024] (3) During irrigation, the invention rotates the first screw, which drives the slide bar to move along the slide groove, thereby driving the top arc plate to move outward, which in turn pushes the water outlet pipe to move with the rotating sleeve, so that the water nozzle can spray water onto the ground in the area where the sugarcane seed stalks are buried, and the water impact force is large, which is convenient for spraying water on the sugarcane roots, making it convenient for the sugarcane roots to absorb water, making it convenient for irrigating sugarcane seedlings, and making it convenient for irrigating the roots of sugarcane during the growth period.

[0025] (4) During the sugarcane growth period, the limiting crossbar is installed on a suitable positioning frame according to the height of the sugarcane, so that the locking bar on the limiting crossbar can be locked into the locking groove on the positioning seat, thereby limiting the movement of the water outlet pipe. When the rotating sleeve rotates counterclockwise, it drives the water outlet pipe to rotate counterclockwise, so that water can be sprayed to irrigate the roots, stalks and leaves of the sugarcane. It is convenient to use and the irrigation range can be controlled by the position of the limiting crossbar, thereby improving the water-saving effect.

[0026] (5) When the water outlet pipe is at the bottom limit position, the water spray head is opened and the water spray head is set towards the sugarcane root position, which can spray water on the sugarcane root. When the water outlet pipe rotates with the rotating sleeve, when the end of the moving plate separates from the end of the top arc plate, the moving plate moves towards the top arc plate side under the elastic force of the guide crossbar. The second connecting groove moves to the water outlet cavity connected to the spray head, so that water is sprayed out from the spray head and sprayed towards the sugarcane, spraying onto the sugarcane stalk and leaves, reducing the impact on the sugarcane itself and protecting the sugarcane.

[0027] (6) The invention uses a second screw threadedly connected to the screw barrel to pull the connecting slider to move. The rotating rods on both sides pull the two top plates closer to each other, causing the spring force of the fourth spring to change, thereby adjusting the friction between the friction plate and the inner wall of the friction groove, adjusting the longitudinal movement speed of the longitudinal plate, and thus adjusting the rotation speed of the rotating sleeve, thereby facilitating the adjustment of the irrigation speed.

A sliding plate 2089 is slidably installed inside the horizontal plate groove 2088. A rotating seat 20810 is rotatably installed at the end of the sliding plate 2089 near the rotating sleeve 203. The rotating seat 20810 is fixedly installed on the outer wall of the rotating sleeve 203. A speed control unit 209 is installed on the outer side of the longitudinal plate 2084.

[0071] The speed control unit 209 includes friction grooves 2091 symmetrically formed on both sides of the longitudinal plate 2084. Sliding grooves 2092 are symmetrically formed on the adjacent sides of the upper and lower horizontal plates 2081. Friction plates 2093 are symmetrically formed on both sides of the longitudinal plate 2084. The two friction plates 2093 are located inside the two friction grooves 2091, and are in contact with the adjacent sides of the two friction grooves 2091. First sliding blocks 2094 are symmetrically installed at both ends of the friction plates 2093, and are slidably installed inside the sliding grooves 2092. Each of the friction plates 2093 has a pressure plate 2095 on one of its opposite sides. A second sliding block 2096 is symmetrically installed at both ends of the pressure plate 2095. The second sliding block 2096 is slidably installed inside the sliding groove 2092. A fourth spring 2097 is equidistantly installed between the pressure plate 2095 and the friction plate 2093. A top groove 2098 is opened at the top of the upper sliding groove 2092. A top plate 2099 is installed at the top of the second sliding block 2096 above the two pressure plates 2095. The top plate 2099 passes through the top groove 2098 and extends above the upper horizontal plate 2081. A fixed box 20910 is installed at the top of 081. Side grooves 20911 are symmetrically opened on both sides of the fixed box 20910. A connecting slider 20912 is slidably installed inside the fixed box 20910. Rotating rods 20913 are symmetrically arranged on both sides of the connecting slider 20912. Rotating seats 20914 are hinged to both ends of the rotating rods 20913. The two rotating seats 20914 are fixedly installed on both sides of the connecting slider 20912 at one end, and the other ends of the two rotating seats 20914 are fixedly connected to two top plates 2099. A third end limiting rod 20915 is rotatably mounted on 0912. A second screw 20916 is located at the end of the third end limiting rod 20915 furthest from the rotating sleeve 203. A screw barrel 20917 is mounted at the end of the fixed box 20910 furthest from the rotating sleeve 203. The second screw 20916 is threadedly connected to the inside of the screw barrel 20917. When installing the sprinkler system, the irrigation pipe 1 is installed near the upper left side of the sugarcane and fixed with a bracket. The irrigation pipe 1 is connected to the water tank. When changing the water in the fishpond, a portion of the water is filtered and stored in the water tank for use during irrigation.

[0072] During installation, the first screw 20614 is turned. Since the first screw 20614 is threadedly connected to the screw groove on the fixing block 2067, the first screw 20614 is moved, which in turn moves the slide rod 2066 along the slide groove 2065, causing the end of the top arc plate 2064 to move. This pushes the water nozzle 2053 at the bottom of the water outlet pipe 2051 toward the ground of the buried sugarcane seed area. When watering is needed before the sugarcane sprouts, the water tank pump is turned on. The water flows through the water outlet 202 on the irrigation pipe 1 into the water channel 204 in the rotating sleeve 203, and sprays directly from the water outlet 2052 onto the ground of the buried sugarcane seed area from the water nozzle 2053.

[0073] During the stages of sugarcane seedling emergence and sugarcane growth, the limiting crossbar 2073 is adjusted and installed on the corresponding positioning frame according to the position of the top of the sugarcane. That is, a suitable positioning frame is selected, and the hand-pinching plates 2079 on the limiting crossbar 2073 are pinched together and brought close to each other, so that the locking rod 2076 enters the inner groove 2074. The limiting crossbar 2073 is placed between the two positioning seats 2071 on the positioning frame. Then the hand-pinching plates 2079 are released, so that the locking rod 2076 moves outward under the elastic force of the second spring 2077, so that the locking rod 2076 is inserted into the slot 2072 on the positioning seat 2071, thereby fixing the limiting crossbar 2073. This allows for adjustment of the range of movement of the water outlet pipe 2051 with the rotating sleeve 203, thus facilitating the corresponding control of irrigation height and sugarcane growth status.

[0074] During irrigation, the water tank pump is turned on, causing water to spray from the nozzle 2053 towards the sugarcane roots. Then, the electromagnet 2087 is energized, attracting the magnetic block 2086, which in turn moves the longitudinal plate 2084 downwards. This, in turn, moves the sliding plate 2089 downwards, causing the rotating sleeve 203 to rotate counterclockwise via the rotating base 20810. This causes the outlet pipe 2051 to move with the rotating sleeve 203. When the end of the moving plate 2056 separates from the end of the top arc plate 2064, the guide crossbar 20512 is in a stretched state. Under the elastic force of the guide crossbar 20512, the moving plate 2056 moves towards the top arc plate 2064, causing the baffle 205... 7. Move to the water outlet chamber 2052 connected to the water nozzle 2053, and move the second connecting groove 2059 to the water outlet chamber 2052 connected to the sprinkler head 2054, so that water is sprayed out from the sprinkler head 2054 and sprayed onto the sugarcane, onto the sugarcane stalk and leaves, saving water and reducing the impact on the sugarcane, thus improving the protection of the sugarcane. After the water outlet pipe 2051 moves with the rotating sleeve 203 to contact the limit crossbar 2073, the rotating sleeve 203 stops rotating. After irrigation, turn off the water pump, de-energize the electromagnet 2087, and cause the longitudinal plate 2084 to move back under the elastic force of the third spring 2085, which in turn drives the rotating sleeve 203 to move back.

[0075] During use, the friction plate 2093 contacts the inner wall of the friction groove 2091 on the longitudinal moving plate 2084. Under the elastic force of the friction plate 2093, the vibration generated by the third spring 2085 is damped. At the same time, when the second screw 20916 is turned, since the second screw 20916 is threadedly connected to the screw barrel 20917, the connecting slider 20912 is pulled to move. Then, the rotating rods 20913 on both sides pull the two top plates 2099 closer to each other, thereby adjusting the distance between the pressure plate 2095 and the friction plate 2093. This causes the elastic force of the fourth spring 2097 to change, adjusting the friction between the friction plate 2093 and the inner wall of the friction groove 2091, thereby adjusting the longitudinal moving speed of the longitudinal moving plate 2084, and thus adjusting the rotation speed of the rotating sleeve 203, which facilitates the adjustment of the irrigation speed.
