Description

Technical Field

[0001] The present invention relates to the technical field of irrigation devices, and more specifically, to an irrigation and fertilization device and a fertilization method for kiwifruit cultivation. Background Art

[0002] Kiwifruit is a fruit tree with relatively high water requirements, being neither drought-tolerant nor waterlogging-tolerant. Therefore, the reasonable selection and correct use of irrigation devices are crucial for the growth of kiwifruit. Kiwifruit has different water requirements at different growth stages. The absorption amount of nutrient elements by kiwifruit is much larger than that of other fruit trees, especially the requirements for chlorine and iron are relatively high. During the period from budding to fruit setting, the accumulated amounts of nitrogen, potassium, zinc, and copper in the leaves account for more than 80% of the total annual accumulation. The absorption of phosphorus and sulfur mainly occurs in spring. The fruit expansion period is a stage when kiwifruit fruits grow and develop rapidly, and nutrient elements such as potassium, nitrogen, and phosphorus gradually transfer from vegetative organs to fruits;

[0003] In the process of kiwifruit cultivation, more specifically, during the budding period, new shoot growth period, flowering period, fruit expansion period, and after fruit harvesting of kiwifruit, different fertilization methods need to be adopted according to different states. Compared with other fruit trees, different requirements are imposed on the irrigation and fertilization methods during kiwifruit cultivation. Therefore, the traditional single irrigation and fertilization device cannot meet all the usage requirements of kiwifruit at different times, and often requires manual additional assistance for supplementary fertilization and watering, which is relatively labor-consuming.

[0059] A fertilization method for kiwifruit cultivation is characterized by including the following steps;

[0060] Step 1 When the kiwifruit tree is in the budding period, compound fertilizers or organic fertilizers rich in nitrogen and phosphorus should be mainly used. Therefore, nitrogen and phosphorus liquid fertilizers are poured into the fertilizer pool 9, and the spraying outer shell 6 is set at the lowest position of the vertical rod 5, and the drip irrigation method is used to supply water and fertilizer to the kiwifruit tree.

[0061] Step 2 When the kiwifruit tree is in the new shoot growth period, fertilize the leaf surface at this time, focusing on supplementing zinc elements. Therefore, a balanced water-soluble fertilizer needs to be used, applied once every about 10 days. The operator fills the irrigation water into the reservoir 8, then replaces the water-soluble fertilizer in the fertilizer pool 9, sets the spraying outer shell 6 in the middle of the vertical rod 5, and then the mixed water-soluble fertilizer and irrigation water are mixed and sprayed on the middle leaves from the fertilizer pipe 19 position, so as to supplement water and fertilizer.

[0062] Step 3 During the flowering period, use quick-acting nitrogen fertilizer as the main component, combined with a small amount of phosphorus and potassium fertilizers to meet the needs of flower bud differentiation and flowering. Set the spraying outer shell 6 at the lowest position of the vertical rod 5, and use the drip irrigation method to supply water and fertilizer to the fruit tree.

[0063] Step 4 When in the fruit swelling period and after fruit harvesting, apply compound fertilizers and organic fertilizers, set the spraying outer shell 6 at the top of the clamping seat 3, and use the sprinkler irrigation method to make the water and fertilizer fully mixed for large-scale spraying, so as to increase fertilizer supply, promote the development and swelling of fruits, and at the same time provide nutrition for the fruit tree, enhance its overwintering ability, and lay a foundation for the growth in the next year.

[0064] Working principle of the present invention: Operators need to make different adjustments to the device according to different periods of kiwifruit trees. When the kiwifruit trees are in the budding period, compound fertilizers or organic fertilizers rich in nitrogen and phosphorus should be used. Liquid nitrogen and phosphorus fertilizers are poured into the fertilizer water tank 9. At this time, the second drive motor 12 is started. The second drive motor 12 pumps the liquid nitrogen and phosphorus water fertilizers in the fertilizer water tank 9 into the fertilizer pipe 19 through the auxiliary pipe 10. The liquid nitrogen and phosphorus fertilizers are poured into the vertical fertilizer pipe 1901 through the fertilizer pipe 19. The main pipeline 7 and the embedded pipe 2 are embedded at a position 3 - 5 cm below the ground. Operators can set the spraying outer casing 6 at the position of the clamping seat 3 at the lowest side of the vertical rod 5. Align the clamping member 25 at the rear of the spraying outer casing 6 with the middle of the limiting plate 31, and vertically insert the spraying outer casing 6 downward into the front side of the clamping seat 3. During the downward movement of the spraying outer casing 6, the first adjusting head 26 at the rear of the spraying outer casing 6 contacts the adjusting member 30. At this time, the adjusting member 30 is forced to press downward, driving the lifting connecting plate 34 downward. The adjusting switch component includes an adjusting member 30 slidably arranged on the front side of the clamping seat 3. A spring is arranged at the lower end of the adjusting member 30, and a lifting connecting plate 34 is fixedly installed on the lower side of the adjusting member 30. A circular groove corresponding to the main water pipe 32 and the auxiliary fertilizer pipe 1902 is opened in the middle of the upper side of the lifting connecting plate 34. When the adjusting member 30 is pressed downward, the adjusting member 30 drives the entire lifting connecting plate 34 to press downward. At this time, the lifting connecting plate 34 moves downward, and the circular groove on the upper side of the lifting connecting plate 34 communicates with the main water pipe 32 and the auxiliary fertilizer pipe 1902. At this time, the water body and fertilizer water in the rotating connecting member 501 and the vertical fertilizer pipe 1901 communicate with the main water pipe 32 and the auxiliary fertilizer pipe 1902. When the adjusting member 30 is pressed to the middle of the lower part, the first adjusting head 26 will be lifted upward by the adjusting member 30. At this time, the first adjusting head 26 drives the first adjusting gear 3501 to rotate upward through the first toothed plate 2601. At this time, the entire adjusting cylinder 36 rotates forward, aligning the fertilizer groove 41 with the adjusting groove 37. The adjusting cylinder 36 is inserted into the upper and lower slots of the sieve plate 38 at the edge of the fertilizer groove 41. At this time, the vertical fertilizer pipe 1901 is connected to the auxiliary fertilizer pipe 1902, and the liquid nitrogen and phosphorus fertilizers ooze out from the drip irrigation head 22 through the fertilizer cylinder 35 and the sieve plate 38. The drip irrigation technology only wets a small area on the soil surface, reducing evaporation loss, and at the same time can continuously supply fertilizers to the kiwifruit trees;

[0065] When the kiwifruit tree is in the new shoot growth period, fertilize the leaf surface at this time, with a focus on supplementing zinc. Therefore, a balanced water-soluble fertilizer needs to be used and applied once every about 10 days. The operator can set the spraying outer casing 6 at the position of the clamping seat 3 in the middle on the side of the vertical rod 5. When the spraying outer casing 6 is clamped downward on the clamping seat 3, after the second adjusting head 27 on the rear side of the spraying outer casing 6 comes into contact with the adjusting member 30, the adjusting member 30 will be pressed downward. When the adjusting member 30 is pressed to the lower side, the same as the above process, the lifting connecting plate 34 connects the auxiliary fertilizer pipe 1902 and the vertical fertilizer pipe 1901. The second adjusting head 27 will drive the second toothed plate 2701 to move. Since the lengths of the first toothed plate 2601, the second toothed plate 2701, and the third toothed plate 2801 increase in sequence, when the second toothed plate 2701 slides, the rotation distance of the adjusting cylinder 36 will also increase, so that the positions of the fertilizer tank 41 and the adjusting groove 37 are slightly offset. At this time, the water storage tank 8 injects irrigation water into the interior of the main pipeline 7 through the first drive motor 11. The irrigation water enters the interior of the main water pipe 32 through the rotating connecting member 501 and finally enters the interior of the spraying outer casing 6. At this time, the drip irrigation head 22 moves to the upper side of the screen plate 38, and the pressure of the irrigation water and the solution water will atomize and spray the irrigation water and the balanced water-soluble fertilizer together from the position of the drip irrigation head 22, so as to spray and fertilize the surface of the leaves of the middle kiwifruit trees;

[0066] During the flowering period, mainly use quick-acting nitrogen fertilizer, combined with a small amount of phosphorus and potassium fertilizers to meet the needs of flower bud differentiation and flowering. The fertilization method is the same as that during the budding period of the kiwifruit tree, and repeat the fertilization steps for drip irrigation glue;

[0067] When in the fruit expansion period and after fruit harvesting, it is necessary to replenish water and fertilizer. Set the spraying outer casing 6 at the position of the clamping seat 3 at the uppermost side of the vertical rod 5, and the adjusting member 30 is pressed to the bottom below. At this time, the third adjusting head 28 on the side of the uppermost clamping seat 3 drives the adjusting cylinder 36 to rotate forward under pressure. At this time, the liquid outlet groove 40 coincides with most of the front fertilizer pipe 19, and the opening position of the adjusting groove 37 overlaps with the lower half position of the liquid outlet groove 40. The water flow can be sprayed and irrigated obliquely upward from the direction of the fertilizer pipe 19 to the kiwifruit tree. The fertilizer output and water output are large, which can quickly increase the soil fertility and enhance the overwintering ability, laying a foundation for the growth of the next year;

[0068] Since the adjustment switch component includes an adjustment member 30 slidably disposed on the front side of the mounting seat 3, a spring is provided at the lower end of the adjustment member 30, a lifting connection plate 34 is fixedly installed on the lower side of the adjustment member 30, and a circular groove corresponding to the main water pipe 32 and the auxiliary fertilizer pipe 1902 is provided in the middle of the upper side of the lifting connection plate 34, only when the spraying outer casing 6 is inserted downward as a whole, the adjustment member 30 will drive the lifting connection plate 34 to move, and the auxiliary fertilizer pipe 1902 can be communicated with the vertical fertilizer pipe 1901. When the spraying outer casing 6 is removed, the lifting connection plate 34 will cut off the auxiliary fertilizer pipe 1902 to close the water path. Therefore, the spraying outer casing 6 can be freely disassembled when the main pipeline 7 is operating normally, effectively avoiding the problems that the traditional watering device is prone to blockage and damage and needs to shut down the whole watering device for maintenance.
