Embodiment 1

[0022] Example 1, see figure 1 : the present invention includes the water storage container 2 with the water inlet 1 on the top. One side of the water storage container 2 has a pressure balance port 3 with a diameter of 8 mm at 5 cm from the bottom. A short pipe 4 is connected to the outer end of the pressure balance port 3, and a switch 6 is installed on the short pipe 4. The other side of the water storage container 2 is provided with a water outlet 5 apart from the bottom 5cm, and the outer end of the water outlet 5 is connected with a switch 6, and the water outlet 5 is connected with the water delivery capillary 7. The water delivery capillary 7 is a PE hose, on which every interval of 30cm is provided with a water outlet hole 8 with a diameter of 6mm, and cotton balls are arranged on the water outlet hole 8 .

[0023] When using the present invention, according to planting crop root system layer depth, for example 20cm, water storage container 2 is horizontally placed ...

Embodiment 2

[0025] Example 2, see figure 2 The difference with the structure in Embodiment 1 is that a lifting device is provided at the bottom of said water storage container 2, and this lifting device includes a bracket 9, a lead screw 10 and a fixed seat 11, and the bracket 9 is connected to the lower part of the water storage container 2. Fixedly connected, the lower part of the lead screw 10 is fixedly connected with the fixed seat 11, and the upper part is threadedly connected with the bracket 9.

[0026] The water consumption of crops is different in different growth stages. The water consumption in the seedling stage is small, and the water consumption in the fruit filling stage is large. Therefore, by rotating the water storage container 2, the position of the water storage container 2 is raised and lowered, and finally the relative height difference between the pressure balance port 3 and the water delivery capillary 7 is adjusted to achieve adjustment. The water output of wat...

Abstract

The present invention relates to agricultural irrigation technology, and is especially one kind of pressure-free locally controlling underground root area irrigation system. The present invention can reach the aims of saving water, saving energy, saving investment and facilitating management. The technological scheme is that the irrigation system includes water conveying pipe with water outlet holes and one closed end as well as water container with water inlet, water outlet and pressure balancing port. The water inlet is provided with detachable sealing cover, and the water outlet with valve and the pressure balancing port are set in the lower part of the water container.

Description

Technical field: [0001] The invention relates to the technical field of agricultural irrigation, in particular to an underground irrigation system for locally controlling water in a rootless zone. Background technique: [0002] At present, advanced agricultural water-saving irrigation technologies include sprinkler irrigation and micro-irrigation. Micro-irrigation includes surface drip irrigation, under-film drip irrigation, underground drip irrigation, underground infiltration irrigation, etc. They are recognized by more and more people for their advantages of increasing production, high quality, saving water, and adapting to various terrains. Micro-irrigation is an irrigation method that uses special equipment to turn pressurized water flow into small water flows and water droplets, and moisten the soil near the roots of crops. It usually includes the first hub, that is, the pressurized water source, the main water delivery pipe, the branch pipe, the capillary pipe, and th...
