Local improving method for high viscosity soil green planting land

Abstract

The invention discloses a local improving method for high viscosity soil green planting land, which comprises the following steps: (a) digging planting holes: digging suitable planting holes according to the sizes of soil balls of the seedlings to be transplanted; (b) preparing an improving medium: according to the characteristics and soil requirements of the seedlings to be transplanted, mixing raw soil, peat soil, acid soil and river sand according to a proper proportion, and stirring uniformly after mixing for later use of planting; and (c) filling the improving medium: in the process of planting the seedlings, spreading some prepared improving medium on the bottom of the planting holes, then putting the planting seedlings on the improving medium, and filling some prepared improving medium uniformly around the soil balls of the planting seedlings. The invention aims to provide the local improving method for the high viscosity soil green planting land for improving the survival rateof seedlings and saving man power, material resources and financial resources.

Description

[technical field] [0001] The invention relates to a method for improving greening and planting land, in particular to a local improvement method for greening and planting land with high viscosity soil. [Background technique] [0002] In urban landscaping, some planting soils are highly cohesive soils (such as the deep soil after the foundation of high-rise buildings are dug), and the high cohesive soils cause the roots of seedlings to be in an anoxic environment due to poor physical and chemical properties of the soil and poor water permeability. , the root system of seedlings cannot breathe normally, which often easily leads to the death of newly planted seedlings. If a large area of ​​soil replacement or soil improvement is carried out, the cost will be very high, so it is imperative to carry out local improvement of high-cohesive soil in greening planting land. [Content of the invention] [0003] The invention overcomes the disadvantages of the above-mentioned technolo...
