Non-planting season big-DBH (diameter at breast height) arbor construction method in intensive-rain region

Abstract

The invention provides a non-planting season big-DBH (diameter at breast height) arbor construction method in a intensive-rain region. The method comprises the following steps of performing flow interception on a riverway, digging tree holes in an original soil layer in a riverway, arranging a filtering layer on the inner bottom surface of each tree hole, and inserting and arranging water discharging pipes in the filtering layers; laying the improved planting soil into the tree holes; planting the arbor into the tree holes through the improved planting soil, and uniformly inserting and arranging a plurality of ventilation pipes in the improved planting soil on the periphery of the arbor; and fixing and supporting the arbor by arranging cedar piles. By using the method, the non-seasonal planting problem in the region with intensive rain and adverse geological conditions can be effectively solved; the water discharging pipe is also used as an observation pipe and realizes two purposes ofone pipe, so that the repeated design and installation can be avoided; when the rainwater quantity is great, the water is pumped by a pump through the water discharging pipes; and at ordinary times,the water level can be observed. Ventilation pipes are arranged around soil balls, so that the soil ventilation capability is improved, and the survival rate is improved. By aiming at the adverse geological conditions, a soil improving method is used; the planting soil is subjected to proportioning improvement; and the survival rate is improved.

Description

Technical field [0001] The invention relates to the technical field of vegetation planting, in particular to a construction method of large-diameter trees in non-planting season in rain-intensive areas. Background technique [0002] At present, as the country attaches great importance to urban infrastructure construction, underground integrated pipe corridors and water environment management projects, more and more cities regard water environment management as a top priority. Improve the river course and re-transplant landscaping. Due to years of siltation and indirect pollution from surrounding villages, factories and construction industries, the planting areas on both sides of the river course have poor soil, most of which are backfilled soil, and there is some construction waste. There are certain difficulties in project construction, and frequent rains in some areas have greatly affected the planting time of seedlings. Many difficulties have caused significant negative effect...
