Mountain economic forest rainwater gathering deep percolation device

Abstract

The invention discloses a mountain economic forest rainwater gathering deep percolation device. A water and fertilizer pit is formed in the uphill face of a fruit tree, a waterproof layer is arranged at the bottom of the water and fertilizer pit, a drainage pipe is vertically installed in the middle of the water and fertilizer pit, and the periphery of the drainage pipe is filled with an organic filler layer. A rain gathering film is laid at the upper end of the water and fertilizer pit, the fruit tree (economic tree) is planted on the slope face of the downhill position on one side of the water and fertilizer pit, a fish scale pit is formed along a trunk of the fruit tree (economic tree) and the water and fertilizer pit, and a water measuring pipe is vertically installed between the trunk and the water and fertilizer pit. According to the device, water-saving irrigation, the water and fertilizer integration technology and water and soil conservation are organically combined, compared with surface irrigation, the effects of water saving, water holding, fertilizer holding, fertilizer promoting, reduction of ammonia volatilization, reduction of water evaporation loss and effective prevention of water and soil loss are achieved, the device is low in cost, simple in technology, easy to operate, good in effect and easy to grasp, and therefore the device has wide application prospects in arid and semi-arid fruit industry regions of China.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a rainwater accumulation deep-layer infiltration device for mountain economic forests. Background technique [0002] The Loess Plateau is recognized as the largest eugenic area for apples in the world, and it is also the only eugenic area in the country that meets the seven climatic indicators required for apple growth. The loess plateau has a high altitude, large temperature difference between day and night, and sufficient sunshine, which is conducive to the accumulation and coloring of apple sugar; the climate is dry, the air humidity is low, the harm of diseases and insect pests is low, the work of disease and insect pest protection is small, and the environmental pollution is relatively light; the loess soil layer is deep and thick , The soil is mainly yellow cotton soil, loose texture, strong air permeability and water storage capacity, suitable f...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rainwater accumulation deep infiltration device for mountainous economic forests, which aims to solve the shortage of water resources in dryland orchards on the Loess Plateau, the distribution of rainwater resources is seriously uneven, and the rainfall cannot infiltrate into the root layer. Water decomposition and low water and fertilizer utilization rate seriously affect the sustainable development of fruit industry in arid areas
