Rainwater-collecting, supplementary-irrigation, infiltration-promoting and flood-draining integrated system for hillside orchard and implementation method thereof

Abstract

The invention discloses a rainwater collection, supplementary irrigation, infiltration promotion and drainage integrated system for a hillside orchard and an implementation method thereof.The rainwater collection, supplementary irrigation, infiltration promotion and drainage integrated system comprises a rainwater collection cellar system, an irrigation branch and a micro rainwater collection, infiltration promotion and drainage system which are sequentially connected, and the rainwater collection cellar system is connected with the irrigation branch and the micro rainwater collection, infiltration promotion and drainage system; comprising a plurality of rainwater collecting cellars arranged along the terrain below the mountain top, and the rainwater collecting cellars are used for collecting rainwater in idle land; an inlet of the irrigation branch is connected with a drainage valve outlet of the corresponding rainwater collection cellar, and an outlet of the irrigation branch is connected with a water inlet of the micro rainwater collection infiltration promotion flood drainage system; the micro rainwater collection infiltration promotion and drainage system comprises infiltration promotion and drainage grooves dug among fruit trees, vertical flow guide infiltration promotion pipes are arranged in the middles of the infiltration promotion and drainage grooves, and water retention and infiltration promotion filling bodies are filled in groove bodies around the flow guide infiltration promotion pipes. The device can play irrigation and flood drainage roles at the same time, and growth of fruit trees is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water-saving irrigation, and in particular relates to a rain-collecting, supplementary-irrigation, infiltration-promoting and flood-draining comprehensive system for mountain orchards and an implementation method thereof. Background technique [0002] Fruit industry is the main industry that increases farmers' income in many regions of my country, such as the apple industry in the Loess Plateau and the citrus industry in the southern red soil region. However, in recent years, extreme meteorological events (storms, droughts) caused by climate change have gradually increased. Droughts have reduced the yield of orchards, and rainstorms have caused the deterioration of fruit tree roots from time to time. Small-scale safeguard measures in traditional orchards, such as rain harvesting supplementary irrigation systems, micro-rain harvesting projects, and micro-irrigation projects, are all facing a trend of decli...

Problems solved by technology

However, due to the impact of climate change, the frequency of extreme weather events in this area has gradually increased, and seasonal droughts and heavy rains have occurred frequently, resulting in a decline in the guarantee rate of the original rain collection and supplementary irrigation system. The bubble root phenomenon occurs from time to time
