Plane root-zone irrigation method and irrigation device

Abstract

The invention discloses a plane root-zone irrigation method and an irrigation device. The irrigation device sequentially comprises a base layer with bearing capacity, an intermedium material arranged above the base layer, and a soil or plant container arranged above the intermedium material and connected or attached to the intermedium material, wherein, the intermedium material can be a membrane material, a coiled material, a sheet material or a plate material which take a spongy, lacunose or fibrous shape and has a function of absorbing and storing a liquid. The invention has the following beneficial effects: 1. water and nutrients are uniformly supplied to a plant, thus ensuring long-term growth of the plant; 2. construction is very simple, convenient and fast: a framework does not need to be built outside structures such as a greened wall surface and the like, as the base layer or a base material can bear the weight of all objects added thereon by means of the strength thereof, and a large number of drip irrigation heads do not need to be mounted; 3. the irrigation device is combined with a waterproof membrane to achieve simple structural levels, wherein, the thickness from a waterproof layer to a plant layer does not exceed 10cm, thus eliminating hidden danger of water leakage and avoiding a plant root penetrating through a wall; and 4. construction cost and maintenance cost are low, thus providing guarantee for wide popularization.

Description

technical field [0001] The patent of the present invention relates to an irrigation technology, in particular to a new planar watering method and device for providing water, fertilizers or other chemicals to the root zone of plants such as wall greening, vertical greening, and three-dimensional greening. Background technique [0002] At present, the water supply or nutrients of plants such as wall greening, vertical greening, and three-dimensional greening mainly use drip irrigation technology. Slowly drip out filtered water, fertilizers or other chemical agents, etc., and the current drip irrigation technology has many shortcomings. For example, the shortcomings mainly contain the following four aspects: 1. 2. It is difficult to ensure the uniformity of drip irrigation; 3. The influence of impurities and mineral precipitation will cause the dripper to be blocked; 4. The above-mentioned system is expensive, and it is not beautiful and convenient. [0003] Therefore, in view...
