Problems solved by technology

[0012] However, in this negative pressure irrigation system, heavy liquid such as mercury needs to be injected into the negative pressure adjustment device. In the actual use process, it was found that after 2 to 3 months of operation, mercury generally oxidized and precipitated, causing the system to stop operating, making the negative pressure irrigation system Utilization efficiency is not high

Abstract

An embodiment of the present invention discloses a device for maintaining constant negative pressure irrigation. The device comprises a penetrating container, a porous medium plate, and a U-shaped container, wherein the penetrating container is of an inverted cup-shaped. An air-out connection is disposed on the top of the penetrating container, and communicates with a communicating hole in a lower portion of a water receiver. The bottom of the penetrating container is open. The porous medium plate is generally fixed by sticking to an inner sidewall of a lower portion of the penetrating container, and the position of sticking of the porous medium plate to the inner sidewall is sealed. The penetrating container is placed in the U-shaped container that is filled with a fluid capable of infiltrating the porous medium plate. Using the device for maintaining constant negative pressure irrigation, continuous and steady running of negative pressure irrigation may be ensured.

Description

technical field [0001] The invention relates to agricultural irrigation technology, in particular to a device for maintaining constant negative pressure irrigation. Background technique [0002] The water transpired by crops in the process of growth and development is often hundreds or even tens of thousands of times of their own biomass. Since the soil is often difficult to provide the water necessary for the growth and development of crops, in the process of modern agricultural production, through irrigation Replenishing water to the soil, and then meeting the water demand of crops, is an essential agricultural activity. However, this traditional irrigation method has a serious waste of irrigation water resources. In order to effectively reduce the waste of water resources, a new irrigation technology has been proposed in the past 10 years, that is, negative pressure irrigation technology has been gradually developed and applied. This technology can effectively Suppressin...
