Embodiment Construction
[0015] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented.
[0016] Such as figure 1 As shown, the movable negative pressure irrigation system of camellia oleifera forest includes an airtight water supply tank 3, a clay head irrigation device 12 and a tee 7. The airtight water supply tank 3 is equipped with a vent pipe 2 and a water injection port 1 with a sealed cover. The airtight water supply tank There is a water outlet pipe 4 at the bottom of the tank 3, and a sealing valve 5 and a water injection exhaust port 6 with a sealing cover are installed on the water outlet pipe 4. The other end of the water outlet pipe 4 is connected to a hor...

The invention relates to an irrigating device and method, and specifically relates to a movable negative pressure irrigating system and method for oil-tea camellia stand. The system comprises a closed water supply tank, an argil head water filing device and a tee joint, wherein the closed water supply tank is provided with a ventilating pipe, and a water pouring opening with a sealing cover; a water discharging pipe is arranged at the bottom part of the closed water supply tank; a sealing valve and a water pouring exhaust opening with the sealing cover are mounted on the water discharging pipe; the other end of the water discharging pipe is connected with a horizontal main pipe through the tee joint; a vertical rough pipe is connected to the main pipe; the tail end of the rough pipe is inserted into a closed pipe full of water; the bottom parts of the closed pipe and the rough pipe are respectively communicated with the argil water filling device; a pressure gage is mounted on the closed pipe; the pressure meter, the closed pipe and the argil head water filling device form a soil tension meter. The device is used for monitoring the water potential in soil and comparing with the negative pressure value of the water potential in soil, corresponding to the water demand threshold value of oil tea in order to determine whether to irrigate water; the water is supplied to the oil tea as requirement, so that the water consumption is reduced; meanwhile, the closed water supply tank is movable and can be applied to hill area in which oil tea grows.
Description
technical field [0001] The invention relates to an irrigation device and an irrigation method thereof, in particular to a movable negative pressure irrigation system and an irrigation method of camellia oleifera forest. Background technique [0002] Camellia oleifera is a unique oil crop in southern my country. In actual production, the unfavorable phenomenon of "dried oil in July and dried fruit in August" is often due to the lack of sufficient water supply and reasonable and balanced water conditions during the seasonal drought period, making it difficult to meet other conditions. Physiological activities and the needs of material synthesis and transformation. At present, there is no standardized irrigation system and method for Camellia oleifera forest, and the extensive irrigation method has some shortcomings: (1) The irrigation water wets the soil area, which may form surface runoff, and the soil moisture evaporates greatly, resulting in waste of water resources; (2) Th...
