Description

Irrigation system for economical greening engineering

Technical Field

The invention relates to the technical field of irrigation prepared in greening engineering, in particular to an irrigation system for economical greening engineering.

Background

The greening engineering is a construction engineering for greening or beautifying the environment, the concept of the greening engineering is basically equal to that of garden engineering, engineering technology in garden construction is taken as a research object, and the greening engineering is characterized in that the image of garden art is shaped by taking the engineering technology as a means.

The basic main body used in the greening engineering is plants, and the applied plants can be summarized into three types of plants, namely herbaceous plants, shrubs and trees, and the heights of the three types of plants are increased. Usually, in order to embody the layering of the greening engineering, the three plants appear in a scene at the same time and are arranged from low to high. And distinguishing two adjacent groups of plant planting areas with different heights, and naming the planting area with the lower plant height as a primary planting area and the area with the higher plant height as a secondary planting area. That is, if three kinds of plants of herbaceous plants, shrubs and trees are planted at a time, two combinations of herbaceous plants and shrubs, shrubs and trees are formed. In the combination of herbaceous plants and shrubs, the herbaceous plant planting area is a primary planting area, and the shrub planting area is a secondary planting area. In the combination of shrubs and trees, the shrub planting area is the primary planting area, and the tree planting area is the secondary planting area. And so on.

Because the greening engineering is to artificially plant, the need of watering can not be avoided. The plants in the greening engineering have the functions of removing and beautifying the environment and purifying the air. This causes a lot of dust to be adsorbed on the leaves of the plants, and thus the leaves of the plants need to be washed while the plants are watered.

Existing irrigation techniques are typically both manual and automated. The manual watering is that the water pipe directly sprays water to the plant, can enough clear the blade of plant, also can let the water infiltration soil of whereabouts, moisten the plant root system. Automatic watering directly carries out the spraying of water to the plant through spray set, has also realized aforementioned two kinds of effects.

Since the height of the trees is greater than that of the shrubs and herbs, water is sprayed from the top of the trees when water is sprayed, so that the leaves of the trees can be washed. However, since trees, shrubs and herbs are staggered, the shrubs and herbs need to be sprayed sequentially after spraying tens of thousands of trees. Resulting in a very large amount of water being used to water the plants.
