Description

Technical Field

[0001] The utility model belongs to the technical field of the planting technology of Ophiopogon japonicus, and particularly relates to a bottom support structure for the bagging planting of Ophiopogon japonicus. Background Art

[0002] Ophiopogon japonicus is a kind of wild yam. The bagging planting of it is a brand-new planting technology. Different from the traditional way that the yam tuber grows vertically downward, it lies flat in a long ecological bag filled with soil on the ground. When the Ophiopogon japonicus tuber grows, due to the blocking effect of the ecological bag wall, it cannot develop vertically downward and can only grow horizontally along the ecological bag. The general bagging planting technology is to directly place the long ecological bag filled with soil flat on the ground surface. The disadvantages are as follows: The ground is usually uneven, and the pits are prone to water accumulation when it rains or is watered, which affects the growth of Ophiopogon japonicus; The ecological bags are placed unevenly with high and low undulations, and the guiding effect of gravity on the growth of Ophiopogon japonicus cannot be effectively reflected, resulting in the overall bending and irregularity of the grown Ophiopogon japonicus tubers, and the product appearance is not good; The ecological bags are close to the ground. When watering or rain forms surface water flow, if the heavy metals or other pollutants in the ground soil exceed the standard, it is easy to enter the ecological bags and pollute the nutrient soil in the ecological bags; In addition, because the water dripped during drip irrigation will seep into the lower soil, it is impossible to directly drip irrigate the bottom side of the ecological bag that fits the ground, and it is difficult to achieve the goal of drip irrigation water saving. Content of the Utility Model

[0003] The utility model provides a bottom support structure for the bagging planting of Ophiopogon japonicus, aiming to overcome at least to a certain extent the above deficiencies existing in the conventional bagging planting technology in the prior art.

[0004] The technical solution for the utility model to solve the above technical problems is as follows: A bottom support structure for the bagging planting of Ophiopogon japonicus, which includes a seat body for supporting a horizontally placed long cylindrical ecological bag from the bottom. A receiving groove is formed on the upper surface of the seat body. The bottom wall of the receiving groove is arranged in a slope shape with one end high and the other end low. A plurality of guide grooves extending from one end to the other end are formed on the bottom wall of the receiving groove. A drain port is arranged at the end of the receiving groove corresponding to the lower end of the bottom wall. A water-saving irrigation mechanism is arranged at the end of the receiving groove corresponding to the higher end of the bottom wall. The water-saving irrigation mechanism includes a sprinkler pipe, a drip irrigation pipe and a water inlet joint pipe connected through a three-way valve. The water outlet end of the sprinkler pipe is connected with a nozzle for spraying water towards the ecological bag. The end of the drip irrigation pipe far from the three-way valve is closed, and water dripping holes corresponding to the guide grooves one by one are formed on the pipe wall.

[0005] On the basis of the above technical solution, the utility model can also be improved as follows.

[0006] Further, the seat body is made of a weather-resistant plastic trough or a precast concrete trough.

[0007] Further, fine sand or permeable fiber cloth is filled in the guide groove.

[0008] Further, the cross-section of the liquid storage tank is arc-shaped, and the included angle between the sloping bottom wall of the liquid storage tank and the horizontal plane is 3-8 degrees.

[0009] Further, the liquid storage tank is open at one end of the slope bottom to form the drain outlet, and a blocking strip is arranged transversely inside the open end at one end of the slope bottom of the liquid storage tank.

[0010] Further, a liquid collection tank is arranged at one end of the top of the slope of the liquid storage tank of the seat body, the bottom of the liquid collection tank is correspondingly communicated with each guide groove, the drip irrigation pipe extends horizontally into the liquid collection tank, and each drip hole drips water into each guide groove in one-to-one correspondence.

[0011] Further, the drip irrigation pipe, the sprinkler irrigation pipe and the water inlet joint pipe are all plastic pipes and are fixedly connected with the seat body through preset fixing holes and / or embedded fixing parts.

[0012] Further, fixing sleeves for fixing climbing poles are preset at the four corners of the seat body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] On the seat body of the bottom support structure for the bagged planting of Fimbrystyx polycarpa provided by the present utility model, there is a liquid storage tank for placing ecological bags, and the bottom of the tank is slightly inclined, so that the open end of the ecological bag is high and the other end is low. On the one hand, because the seed potato is located at the higher bag mouth during sowing, during the later growth of the Fimbrystyx polycarpa tubers, due to the action of gravity, they will spontaneously grow along the slope towards the tail direction of the ecological bag. Moreover, the bottom side wall of the ecological bag contacts the sloping bottom of the liquid storage tank, and is relatively straight in the slope direction, which is beneficial to growing straight and good-looking Fimbrystyx polycarpa tubers. On the other hand, because Fimbrystyx polycarpa is drought-tolerant and afraid of waterlogging, when there is more rain, the bottom of the liquid storage tank is inclined and the bottom of the tank is provided with a guide groove, which can drain water quickly, ensure that there is no water accumulation in the ecological bag, and the Fimbrystyx polycarpa tubers in the bag are basically not soaked in water, and the quality is better; at the same time, the fine sand filled in the guide groove and dripping water into the fine sand from the upper end are also beneficial to the realization of water-saving drip irrigation.

[0015] In addition, after the seat body is set, the ecological bag is isolated from the ground. Even if the land below is a plot with high salt, high heavy metal content or other non-volatile harmful substances, since the ecological bag does not directly contact the ground surface, surface water and harmful substances will not enter the ecological bag. Therefore, the device of the present invention can also be used to grow high-quality and harmless Fimbrystyx polycarpa products in some polluted plots. Description of the Drawings

[0021] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0022] In the description of the present utility model, if terms indicating directions such as "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc. are used, the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as a limitation to the present utility model.

[0023] As Figures 1 to 3 shown, the present utility model provides a bottom support structure for the bagging cultivation of Oxytropis aciphylla, which includes a seat body 1 for supporting a long tubular ecological bag placed flat from the bottom. A holding tank 2 is provided on the upper surface of the seat body 1. The bottom wall of the holding tank is arranged in a slope shape with one end high and the other end low. A plurality of guide grooves 3 extending from one end to the other end are provided on the bottom wall of the holding tank. A drain port is provided at the lower end of the bottom wall of the holding tank corresponding to the lower end of the bottom wall, and a water-saving irrigation mechanism is provided at the higher end of the bottom wall of the holding tank corresponding to the higher end of the bottom wall. The water-saving irrigation mechanism includes a sprinkler pipe 5, a drip irrigation pipe 6 and a water inlet joint pipe 7 connected through a three-way valve 4. The water outlet end of the sprinkler pipe 5 is connected with a nozzle for spraying water towards the ecological bag. One end of the drip irrigation pipe 6 far from the three-way valve 4 is closed, and water dripping holes corresponding to the guide grooves 3 one by one are provided on the pipe wall. The seat body 1 is preferably made of a weather-resistant plastic tank or a precast concrete tank. In order to enable the guide grooves 3 to have a better effect of assisting drip irrigation, fine sand 8 or permeable fiber cloth can be filled in the guide grooves 3.

[0024] It should be noted that the seat body 1 can effectively overcome the problems of difficult drainage and easy water accumulation of the ecological bags directly placed on the ground when there is a lot of rain due to the low and uneven ground surface. Moreover, if the ecological bags are placed unevenly with high and low undulations, the shape of the cowtail knotweed is more likely to be irregularly distorted during growth, affecting the quality. The number of the guide grooves 3 can be only one or multiple. When the number is only one, it should be arranged at the lowest part of the bottom of the holding groove. It is preferably to fill the guide groove 3 with fine sand 8 or a water-permeable fiber cloth with good water conduction performance. In this way, when the ecological bags filled with nutrient soil are placed flat in the holding groove, the side walls of the ecological bags can press on the fine sand 8 or the water-permeable fiber cloth in the guide groove 3. Since the water absorption and water permeability of the fine sand 8 or the water-permeable fiber cloth are better than those of the mixed organic matter nutrient soil, when it rains or is irrigated, the excess water can be drained relatively quickly obliquely downward through the guide groove 3, avoiding the waterlogging damage to the roots of the cowtail knotweed in the ecological bags. In addition, the seat body 1 is not necessarily a weather-resistant plastic groove or a precast concrete groove, and can also be made of ceramics or other weather-resistant and relatively low-cost materials. When conditions permit, a seat body 1 structure composed of adobe can also be formed by ridging and grooving on the ground.

[0025] In an embodiment of the present invention, as Figure 3 shown, the cross-section of the holding groove is arc-shaped, and the included angle between the sloping bottom wall of the holding groove and the horizontal plane is 3-8 degrees. The holding groove is open at one end of the slope bottom to form the drainage port, and a blocking strip 9 is arranged horizontally inside the open end at one end of the slope bottom of the holding groove.

[0026] It should be noted that the blocking strip 9 plays a role in tightly limiting the tail end of the ecological bag to prevent it from sliding downward in the holding groove. The included angle between the sloping bottom wall of the holding groove and the horizontal plane is preferably 3-5 degrees to avoid the too fast water filtration from the guide groove 3 and the bottom of the holding groove, resulting in water shortage of the cowtail knotweed seedlings growing at the upper opening. In addition, when there is little rain and a long-term drought in the year when the cowtail knotweed is planted, the drainage port at the lower end of the guide groove 3 can also be temporarily blocked with clay or rubber blocks to reduce drainage. When conditions permit, a structure similar to a gate that can move up and down vertically can be arranged at one end of the slope bottom of the seat body 1. When there is a lot of rain, the gate is lifted upward to open the drainage port to accelerate drainage, and when there is little rain and drought, the gate is lowered to close the drainage port to improve the water retention capacity.

[0027] In an embodiment of the present invention, a liquid collecting groove 10 is arranged at one end of the slope top of the holding groove of the seat body 1. The bottom of the liquid collecting groove 10 is correspondingly communicated with each of the guide grooves 3. The drip irrigation pipe 6 extends horizontally into the liquid collecting groove 10, and each of the drip holes drips water into each of the guide grooves 3 in one-to-one correspondence.

[0028] It should be noted that in addition to the function of allowing the drip irrigation pipe 6 to extend into the liquid collecting tank 10 so that the drip irrigation pipe 6 can drip water onto the upper ends of the downward guide grooves 3, the liquid collecting tank 10 also has the function of temporarily accumulating liquid so that the liquid slowly penetrates downward through the guide grooves 3 and fully wets the side walls below the ecological bags. That is, it can control the water inlet pressure of the drip irrigation pipe 6 and adjust the water dripping speed of its water dripping holes. When the water pressure is relatively high, the dripping becomes spraying, and there will be accumulated water in the liquid collecting tank. The accumulated water slowly penetrates along the slope top through the fine sand 8 or permeable fiber in the guide groove 3. Since the bottom of the side wall of the ecological bag is pressed on the fine sand 8 or permeable fiber, if the nutrient soil in the ecological bag lacks water, it will also absorb the water in the guide groove 3, thereby soaking the fibrous roots on the tuber of the cow-tail vine, achieving the effect of directly and quickly watering the root system of the cow-tail vine. The water consumption of this method is less than that of the method of directly spraying and infiltrating from above. This method has a better effect on promoting the growth of the cow-tail vine. The principle is similar when applying liquid fertilizer. At this time, the water inlet joint pipe 7 can be connected to the equipment for pumping fertilizer liquid medicine. The fed liquid medicine enters the liquid collecting tank 10 and penetrates downward along the guide groove 3. It should be noted here that the fibrous roots during the development period of the cow-tail vine tuber are very numerous and slender. A part of the fibrous roots can penetrate through the bottom of the side wall of the ecological bag and extend into the fine sand 8 in the guide groove 3 to absorb water or fertilizer liquid. In order to ensure that more fibrous roots can penetrate through the ecological bag, when selecting the ecological bag, an ecological bag with slightly larger pores on the side wall can be selected.

[0029] In an embodiment of the present invention, the drip irrigation pipe 6, the sprinkler irrigation pipe 5, and the water inlet joint pipe 7 are all plastic pipes and are fixedly connected to the seat body 1 through preset fixing holes and / or embedded fixing parts.

[0030] It should be noted that the embedded fixing parts can be brackets with quick pipe clamps or clips.

[0031] In an embodiment of the present invention, fixing sleeves 11 for fixing climbing poles are preset at the four corners of the seat body 1.

[0032] It should be noted that the fixing sleeves 11 do not necessarily have to be provided at the four corners of the seat body 1. Two fixing sleeves 11 can also be provided on both sides of the higher end of the seat body 1, and then two fixing sleeves 11 can be provided on both sides of the middle area of the seat body 1. The main function of the fixing sleeves 11 is to facilitate the direct insertion and fixation of the lower ends of the climbing poles, which is convenient for quickly and stably installing the climbing frame when it is necessary to set up a climbing frame for the cow-tail vine vines.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
