Description

Technical Field

[0001] The present application relates to the technical field of desert plant irrigation, and in particular to a root zone infiltration irrigation device and method for plants in a desert transition zone. Background Art

[0002] Desertification is extremely harmful to the ecological environment. Desert expansion leads to significant changes in the physical, chemical and biological properties of the soil, coarsening of the soil texture, and a sharp decline in soil fertility, which undermines the stability and integrity of the ecosystem. The vegetation coverage in desertified areas has dropped sharply, biodiversity has been damaged, and the ecological service function has been seriously weakened. Desertification can also trigger a series of chain reactions such as frequent sandstorms and aggravated water shortages, which have a negative impact on the ecological environment in the surrounding areas.

[0003] Desert transition zone plants are an important part of desertification control and ecological balance maintenance. They have strong adaptability in extremely arid environments, can provide habitats and food sources for other organisms, and greatly enrich the biodiversity of desert ecosystems. The root system of desert transition zone plants can efficiently fix the soil, effectively curb wind and sand erosion, and has the ecological function of significantly reducing soil and water loss. At the same time, they regulate the local climate through transpiration, increase air humidity, and optimize the microclimate environment in the desert transition zone. Some desert transition zone plants also have special physiological mechanisms that can absorb and store water.

[0004] Root zone irrigation technology has many significant advantages in sandy soil environments. Root zone irrigation technology can accurately deliver water to the root area of ​​plants, greatly reducing water loss during transportation and evaporation, significantly improving water resource utilization efficiency, and is particularly advantageous for sandy soils with poor water retention. Root zone irrigation does not destroy the soil structure during irrigation, helps maintain soil permeability and fertility, and creates a good rhizosphere environment for plant growth.

[0030] The current mainstream irrigation methods for desert plants in the oasis-desert transition zone are drip irrigation and water collection irrigation. However, in actual applications, drip irrigation is easily covered by wind and sand in the desert transition zone, causing blockage. The evaporation intensity in the desert is high, and drip irrigation drops irrigation water on the surface and then evaporates and loses a lot. The effective soil moisture storage time is very short. Water collection irrigation mainly depends on natural precipitation, but precipitation in desert areas is extremely unstable, and it is difficult for water collection irrigation to meet the survival needs of crops. In addition, water collection irrigation is restricted by terrain, and the water collection tank is easily affected by wind and sand. Compared with the current mainstream irrigation technology in the desert transition zone, the device and method proposed in this embodiment accurately monitor the water dynamics of plant roots on the basis of solving the lack of intelligent irrigation technology, and irrigate according to the actual water demand of plants; use seepage pipes to connect drippers for targeted irrigation while effectively solving the problem of dripper blockage; and use seepage pipes to directly transport water to the underground soil layer where crop roots grow, effectively avoiding ineffective evaporation, prolonging the storage time of effective soil water, and being beneficial to the root development and plant survival of plants in the desert transition zone.

[0045] Specifically, S1 includes:

[0046] S11: Use drones to calculate the total area that needs irrigation in the oasis-desert transition zone, and divide the irrigation area based on the distribution locations of water sources and irrigation heads in the area.

[0047] S12: Determine the specification parameters of each device in the device according to the growth habits of the plants in the irrigation area.

[0048] Specifically, the growing season, growth stage and evaporation and transpiration of the main plants in the transition zone desert area are monitored, and the crop water requirement is calculated using the Penman formula; UAV remote sensing monitors the plant growth status and area in the irrigation area, and the irrigation project including the diameter and pressure of the water main pipe 5 and the water branch pipe 6 is designed according to the water required for each irrigation area.

[0049] The solenoid valve 4 is an electro-hydraulic proportional valve, which is used to control the output flow rate, pressure, etc. of the irrigation head 3. The water main pipe 5 and the water branch pipe 6 are heat-resistant and cold-resistant PE pipes. The connecting hose 8 is a PE hose with a length of 30 cm.

[0050] The water delivery branch pipe 6 is laid on both sides of the main roots of water-demanding plants in the irrigation area. Water holes are drilled on the water delivery branch pipe 6 according to the distribution law of plants. The size of the water holes matches the diameter of the connecting hose 8.

[0051] The corrugated tube 13 of the seepage pipe 9 is made of PVC, with a length of 20 cm and a diameter of 5 cm. The tube wall is provided with 4 rows and 4 columns of evenly distributed elliptical protrusions 11, and the protrusions 11 are provided with evenly distributed seepage holes 12 with a diameter of 0.05 cm.

[0052] S13: Select multiple key points in the irrigation area to bury sensors 10, and bury the seepage pipes 9 next to the root systems of plants in the irrigation area.

[0053] Among them, a solar power generation device is placed in the irrigation header 3 and connected to the intelligent processing terminal 2; five key points are selected in the irrigation area to bury sensors 10, with a burial depth of 60 cm. The sensor 10 sends monitoring data to the intelligent processing terminal 2 in time steps; the solenoid valve 4 is installed on the water main 5 connected to the irrigation header 3, and the solenoid valve 4 is controlled by the intelligent processing terminal 2.

[0054] A water main pipe 5 made of PE with a pipe diameter of 75 mm is connected behind the solenoid valve 4. The direction of the water main pipe 5 is determined with reference to the topography and plant distribution of the irrigation area. Water branch pipes 6 made of PE with a length of 32 mm are connected on both sides of the water main pipe 5. The laying of the water branch pipes 6 needs to involve the main crop distribution areas in the region, and the ends of the water branch pipes 6 are blocked.

[0055] According to the actual distribution points of plants, holes are drilled on both sides of the water delivery branch pipe 6 and connected to a 30 cm long connecting hose 8 through a 2L / h dripper 7. The connecting hose 8 is connected to a seepage pipe 9 with a length of 20 cm and a diameter of 5 cm.

[0060] S22: The intelligent processing terminal 2 analyzes the monitoring data of the sensor 10 and automatically controls the solenoid valve 4 to conduct when the moisture content reaches the point where the plant wilts or the soil temperature exceeds 40°C.

[0061] Specifically, if the sensor 10 is a moisture sensor, when the soil moisture measured by the sensor 10 is lower than the plant wilting moisture content, the intelligent processing terminal 2 controls the solenoid valve 4 to be turned on.

[0062] If the sensor 10 is a temperature sensor, when the soil temperature measured by the sensor 10 exceeds 40° C., the intelligent processing terminal 2 controls the solenoid valve 4 to be turned on.

[0063] Specifically, irrigation water is extracted from the irrigation head 3, enters the water supply main pipe 5 through the solenoid valve 4, and is then transported to the connecting hose 8 in the crop distribution area within the region through each water supply branch pipe 6. The dripper 7 controls dripping, and the water droplets enter the seepage pipe 9 and penetrate into the soil in the main root distribution area of ​​the plant through the seepage holes 12 on the convex body 11 on the pipe wall. After the irrigation starts, the sensor 10 continuously monitors the soil moisture and temperature. After the intelligent processing terminal 2 analyzes that the monitoring data reaches the average water requirement of the plant or the temperature is lower than the daily average temperature, it closes the solenoid valve 4 to end the irrigation.
