[0001] This utility model relates to the field of drip irrigation equipment technology, and in particular to a suspended drip irrigation device for jujube trees. Background Technology

[0002] The jujube tree is a common deciduous tree or shrub belonging to the genus Ziziphus of the family Rhamnaceae. Native to China, it is one of China's endemic plants, with a cultivation history spanning thousands of years. In China, jujube trees are widely distributed in the middle and lower reaches of the Yellow River. Among them, the grey jujube is a superior variety, named for its slightly greyish-brown color when ripe. Grey jujubes are mainly produced in Xinjiang, especially in Ruoqiang County, and are known as "Ruoqiang Grey Jujubes." It is one of China's geographical indication products. The jujube tree is not only an important economic forest tree but also a significant symbolic plant in traditional Chinese culture, often associated with good fortune and longevity. Irrigation is necessary during jujube tree cultivation, and artificial watering is used to meet the tree's growth and development needs.

[0003] Existing irrigation systems typically employ surface drip irrigation. However, surface drip irrigation often conflicts with the space available for agricultural operations, making it difficult to integrate the irrigation method with the planting and harvesting of jujube trees. This affects the normal progress of agricultural operations and reduces the overall effectiveness of the system. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] The jujube tree has a unique morphological characteristic. It typically grows to a height of 3 to 10 meters, with a spherical or elliptical crown. The bark is grayish-brown with irregular longitudinal fissures. The twigs are slender and usually bear thorns, which are branch thorns. There are two types: straight thorns (modified branches) and curved thorns (modified leaf axillary buds). These thorns provide a degree of defense, preventing animals from gnawing on the branches. The jujube tree's leaves are alternate, ovate or ovate-lanceolate, approximately 3 to 7 centimeters long and 1.5 to 3 centimeters wide. The leaf tip is acuminate, the base is oblique, and the margins are serrated. The upper surface of the leaf is green and relatively smooth, while the lower surface has short, soft hairs. The petioles are relatively short and also have soft hairs on their upper surface.

[0022] The jujube tree has small, pale yellow, hermaphroditic flowers, typically in cymose inflorescences growing in the leaf axils, with a flowering period generally from May to June. Its fruit is a drupe, varying in shape from round, oval, to oblong, with size varying depending on the variety, generally about 1 to 2.5 centimeters in diameter. The skin is red or purplish-red, the flesh is relatively thick, with a fine texture, and a sweet taste. It is rich in nutrients, including sugars, proteins, vitamin C, B vitamins, and minerals, making it a highly nutritious fruit. Jujube fruit can be eaten fresh or processed into various products, such as red dates, black dates, date paste, date cakes, and date wine, giving it high economic value.

[0023] Jujube trees are highly adaptable to their environment. They are drought-tolerant, flood-tolerant, salt-tolerant, and tolerant of poor soil, growing in various soil types, including sandy soil, loam, and clay. They also have a wide tolerance for soil pH, thriving in environments with a range from 5.5 to 8.5. Furthermore, they are relatively cold-hardy, able to overwinter safely in temperatures as low as -20 degrees Celsius. They can be planted in most parts of my country, from Northeast to South China, and from coastal to inland areas. Jujube trees have a well-developed root system with a strong ability to hold soil in place, preventing soil erosion and making them an excellent species for soil and water conservation. They also absorb harmful gases from the air, purifying it and contributing to the improvement of the ecological environment.

[0024] Jujube trees can be propagated primarily through seed propagation, grafting, and cutting propagation. Seed propagation involves collecting mature jujube fruits, extracting the seeds, processing them, and then sowing them. Offspring propagated this way exhibit greater variation, but it can be used for breeding new varieties. Grafting is one of the most common propagation methods for jujube trees. By grafting scions of superior varieties onto rootstocks, the superior traits of the parent plant can be maintained, improving propagation efficiency. Common grafting methods include bud grafting and branch grafting. Cutting propagation utilizes jujube tree branches for propagation. This method has relatively high requirements for the branches; generally, healthy, disease-free branches should be selected as cuttings. After planting, maintaining suitable temperature and humidity is crucial to improve the survival rate of the cuttings.

[0025] Several management measures are needed during the cultivation of jujube trees, including shaping and pruning, fertilization, watering, and pest and disease control. Shaping and pruning are crucial aspects of jujube tree management. Proper pruning can regulate the balance between tree growth and fruiting, improve ventilation and light penetration, and enhance fruit quality and yield. Fertilization is essential for providing nutrients to jujube trees. Fertilization is generally carried out before bud break, before flowering, during fruit enlargement, and after harvest. Types of fertilizer include organic and chemical fertilizers. Organic fertilizers improve soil structure and increase soil fertility, while chemical fertilizers provide a rapid supply of nutrients. Watering should be based on the jujube tree's growth stage and soil moisture. Although jujube trees are relatively drought-tolerant, they still require adequate water during the growing season, especially during flowering and fruit enlargement. The soil should be kept moist but not waterlogged, as this can lead to root rot. Jujube trees are susceptible to a variety of diseases and pests. Common diseases include jujube witches' broom, jujube rust, and anthracnose. Common pests include jujube looper, jujube leafminer, and peach fruit moth. To control diseases and pests, integrated management measures should be adopted, which include a combination of agricultural, physical, and chemical control methods, minimizing the use of chemical pesticides to ensure the safety and quality of the fruit.

[0026] During the jujube tree's growth cycle, there are several key periods requiring special attention to irrigation. Firstly, before spring budding, the jujube tree enters its vigorous growth period. Sufficient water promotes root activity and new shoot growth, laying a good foundation for the entire year's growth. Generally, after the soil thaws, a thorough irrigation should be carried out in conjunction with fertilization, bringing the soil moisture content to about 60% to 70% of field capacity. This effectively promotes the growth of the jujube tree. Secondly, during the flowering period, the jujube tree is more sensitive to water requirements. Insufficient water will lead to decreased pollen viability, affecting pollination and fertilization, and thus reducing the fruit set rate. Therefore, about a week before flowering, a moderate irrigation should be carried out, keeping the soil moist but not too wet, which helps improve the fruit set rate and creates favorable conditions for fruit formation. However, the amount of irrigation during the flowering period should not be too large, otherwise it may cause flower and fruit drop. At the same time, continuous rainy weather should be avoided during the flowering period, as excessive water will wash away pollen, affecting pollination effectiveness.

[0027] During the fruit enlargement stage, jujube trees reach their peak water demand. At this time, the fruit grows rapidly, and sufficient water supply can promote fruit enlargement, improve fruit quality and yield. Irrigation should be carried out according to soil moisture and weather conditions, generally every 7 to 10 days, maintaining soil moisture content between 70% and 80% of field capacity to ensure that the fruit can fully absorb nutrients and water, promoting its growth and development. However, it is important to avoid flooding, as this can cause root hypoxia and soil compaction, affecting the normal growth and absorption function of the roots. Water-saving irrigation methods such as drip irrigation and micro-sprinkler irrigation can be used, which can meet the water needs of jujube trees and improve water resource utilization efficiency.

[0028] During the jujube harvest season, irrigation requires careful management. At this stage, the fruit is ripe, and excessive moisture may cause it to crack, affecting its appearance and quality and reducing its commercial value. Therefore, irrigation should be stopped 10 to 15 days before harvest to allow the soil to remain moderately dry, reducing the occurrence of cracking and ensuring the quality and storage life of the fruit. Jujube irrigation needs to be comprehensively considered and rationally arranged based on factors such as its growth stage, soil type, climate conditions, and local water resources. Through scientific irrigation management, the growth quality and fruit yield of jujube trees can be effectively improved, bringing better economic benefits to jujube farmers.

[0029] like Figures 1-5 As shown, a suspended drip irrigation device for jujube trees includes a hoop ring 1 and a positioning tube 2. The hoop ring 1 is provided in two sets, and the positioning tube 2 for transmitting water flow for drip irrigation is installed at the outer end of the hoop ring 1. A connecting cylinder 3 for adjustment is installed on the outer side of the hoop ring 1. A locking block 5 is fixed on the outer wall of the connecting cylinder 3. The connecting cylinder 3 is sleeved with the hoop ring 1 through the locking block 5. A screw 4 for adjusting the binding of the hoop ring 1 to the tree trunk is installed inside the connecting cylinder 3. Rubber filling sheets 6 are provided on the inner walls of both sets of hoop ring 1. The two sets of rubber filling sheets 6 are fitted with the hoop ring 1.

[0030] Please see Figures 2-4 Two sets of splicing pipes 7 are installed on one side of the positioning pipe 2. One end of each set of splicing pipes 7 is fixed with a connecting plate 13. Screws are installed circumferentially inside the connecting plate 13. The splicing pipe 7 is connected to the positioning pipe 2 through the connecting plate 13. The end of the positioning pipe 2 away from the splicing pipe 7 is fixed with a docking plate 8 that is connected to the water pipe. Bolts are installed circumferentially inside the docking plate 8. The outer walls of the positioning pipe 2 and the splicing pipe 7 are provided with steel wire ropes 11. Nylon ropes 9 are provided on the outer sides of the positioning pipe 2 and the splicing pipe 7. The positioning pipe 2 and the steel wire ropes 11 are tied to the hoop 1 through the nylon ropes 9.

[0031] Please see Figures 3-5The outer end of the splicing pipe 7 is provided with a binding strap 12. The splicing pipe 7 is connected to the steel wire rope 11 through the binding strap 12. The outer walls of the splicing pipe 7 and the positioning pipe 2 are both fixed with nozzles 10 on one side of the binding strap 12 and the nylon rope 9. The splicing pipe 7 is connected to the positioning pipe 2 and the nozzles 10. The outer wall of the splicing pipe 7 is equipped with a cloth strip 14. The cloth strip 14 has a connecting hole inside. The outer wall of the cloth strip 14 is provided with two sets of connecting ropes 15. The cloth strip 14 is limited and fixed to the splicing pipe 7 through the two sets of connecting ropes 15.

[0032] When irrigating jujube trees, firstly, the connecting tube 3 is used to connect the hoop 1 to the outer wall of the trunk at both ends of each row in the plantation, reducing friction damage to the bark. A rubber filler 6 is placed between the trunk and the hoop. After adjusting the hoop 1 to the designated hanging height, the tool is used to connect the screw 4 and rotate it. The screw 4 is used to connect the hoop 1 to shrink and fit the rubber filler 6 to the trunk. Two steel wire ropes 11 are set on each side of the hoop 1, and two positioning pipes 2 are laid. Two steel wire ropes 11 and positioning pipes 2 are fixed to the hoop 1 on the two outermost trunks using nylon ropes 9. According to the spacing of the tree trunks, a suitable length of splicing pipe 7 is selected. The connecting plate 13 is used to assist in connecting the splicing pipe 7 to the positioning pipe 2, allowing the splicing pipe 7 to drip irrigate the trunk at the designated hanging position. The splicing pipe 7 and the positioning pipe 2 are connected. The outer end of pipe 2 is evenly pierced by steel wire rope 11. The splicing pipe 7 is bound to the steel wire rope 11 by strap 12 to support the drip irrigation pipe and keep it suspended, ensuring relative horizontality. This makes the arrangement of positioning pipe 2 and splicing pipe 7 consistent with the layout of jujube trees. Next, connecting rope 15 is used to connect and fix the cloth strip 14 to the outer wall of splicing pipe 7, so that it can be closely bound to the tree trunk to prevent it from shifting or shaking during drip irrigation. When drip irrigation is needed, the nozzle 10 at the lower end of positioning pipe 2 and splicing pipe 7 is used for drip irrigation. After positioning pipe 2 and splicing pipe 7 are connected and installed, the docking plate 8 is connected to the water pipe to transmit water flow. The water flow passes through positioning pipe 2 and splicing pipe 7 and uses the kinetic energy of compressed gas flow from nozzle 10 to disperse the liquid into a mist, increasing the coverage area and making the spraying effect more uniform, thus realizing the suspended drip irrigation of jujube trees.
