Rainwater collecting and deep infiltrating method for economic forest in mountainous region

Abstract

The invention discloses a rainwater collecting and deep infiltrating method for an economic forest in a mountainous region. The method comprises the steps that water and fertilizer pits are dug under tree crowns; after the distribution positions of the water and fertilizer pits are determined, excavating construction of the water and fertilizer pits is carried out along the uphill flat ground of fruit trees firstly; after the water and fertilizer pits are excavated, waterproof layers are laid at the bottoms of the pits; drainage pipes are put in the middles of the water and fertilizer pits; the peripheries of the drainage pipes are filled with porous organic filler layers and compacted, and then are covered with soil, treaded and trimmed into a concave shape when the peripheries are filled to pit opening parts; square soil ridges with the height of 5 cm are built at the parts away from the walls of infiltrating pits by 10 cm; the square soil ridges are covered with plastic films cut into 120 cm*120 cm; the peripheries of the soil ridges are sealed with soil and properly compacted, and semicircular fish-scale pits are built along trunks with the water and fertilizer pits as centers. By means of the method, the water-saving irrigation technology, the water and fertilizer integrated technology and water and soil conservation are organically combined together, and the effects of saving water, retaining water and fertilizer, promoting fertility, reducing ammonia volatilization and effectively preventing water and soil loss are achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a deep-layer infiltration method for rainwater accumulation in mountainous 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 is an apple eugenic area with 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 protection against diseases and insect pests is small, and the environmental pollution is relatively light; the loess soil layer Deep and thick, the soil is mainly yellow cotton soil, loose texture, strong air permeability an...
