Northern mountainous area fruit tree water and fertilizer integrated water-saving irrigation system

Abstract

The invention discloses a northern mountainous area fruit tree water and fertilizer integrated water-saving irrigation system which comprises an electrical control device, a water storage and drainagesystem, a water transportation pipe network and an irrigation mechanism. The water storage and drainage system provides water and fertilizer for the irrigation mechanism by the water transportation pipe network; the irrigation mechanism is used for carrying out drop irrigation on fruit trees; the water storage and drainage system comprises a main reservoir, a facing-sun auxiliary reservoir and adownsun auxiliary reservoir; the bottom of each auxiliary reservoir is respectively connected with an auxiliary reservoir water outlet pipe; each auxiliary reservoir water outlet pipe is communicatedwith the main reservoir downwards; the water transportation pipe network comprises a water transportation main pipe; the water transportation main pipe is connected with a plurality of water transportation branch pipes; each water transportation branch pipe is connected with a plurality of tail-end pipelines; a drop irrigation electromagnetic valve is respectively arranged on each tail-end pipeline; the irrigation mechanism comprises a soil humidity sensor, a chemical sensor for monitoring concentration of the soil fertilizer, a drop irrigation hole and a water dropper. The northern mountainous area fruit tree water and fertilizer integrated water-saving irrigation system is high in water and fertilizer utilization rate, uniform in water obtained by root systems of the fruit trees and convenient to add the fertilizer into the water, and the water and the fertilizer are prevented from overflowing at the position of a fertilizer transportation pipe.

Description

technical field [0001] The invention relates to the technical fields of agriculture and water conservancy, in particular to an irrigation system for fruit trees in mountainous areas. Background technique [0002] The arid mountainous areas in northern my country lack water resources, poor agricultural production conditions, less rainfall, uneven temporal and spatial distribution of rainfall, and concentrated rainfall periods. 75%-85% of annual precipitation is concentrated in June-September, and spring droughts and droughts often occur. Autumn drought phenomenon. Moreover, the mountainous terrain changes greatly and the terrain is complex, which is not conducive to the construction of long-distance pumping station water delivery projects. [0003] It is difficult to develop groundwater resources in mountainous areas. The depth of wells in most areas is 100-200 meters, and some reach 300-400 meters. It is difficult and expensive to drill wells in arid mountainous areas. When ...

Moreover, the mountainous terrain changes greatly and the terrain is complex, which is not conducive to the construction of long-distance pumping station water delivery projects

[0003] It is difficult to develop groundwater resources in mountainous areas. The depth of wells in most areas is 100-200 meters, and some reach 300-400 meters. It is difficult and expensive to drill wells in arid mountainous areas. When the geological conditions of rock formations are met, the cost of drilling wells is more than 1 million yuan, which is high.

In addition, the traditional irrigation method is ground flood irrigation, which seriously wastes water resources and increases the contradiction between supply and demand of water resources.

In the irrigation method of ground flooding, the fertilizer contained in the water is wasted along with the waste of water resources, which increases the cost
