Abstract

The invention discloses a forest soil remediation method, and belongs to the field of soil remediation. The method comprises the steps of determining the degree of soil acidification, preparing remediation powder particles, forming double-row remediation balls, finally putting the remediation balls into forest soil, and the like. According to the invention, the double-row remediation balls are putinto acidified forest soil, so that chemical remediation and biological remediation can be conducted on the forest soil at the same time; under the arrangement of the attachment wires, the attachmentdegree between the multi-antenna soil particle balls and the remediation powder particles can be improved; and under the cooperation of the effect of the extension antennas, the adhesion degree of the multi-antenna soil particle balls can be increased when the multi-antenna soil particle balls are fed into forest, so that the multi-antenna soil particle balls are not prone to large displacement under the action of wind power or rainwater, then the situation that the multiple multi-antenna soil particle balls are distributed in a centralized mode is effectively avoided, and the restoration effect on forest soil is more uniform, and efficiency is higher.

Description

technical field

[0001] The invention relates to the field of soil remediation, more specifically, to a forest soil remediation method. Background technique

[0002] Soil acidification is one of the main forms of soil degradation. With the rapid development of the economy, my country's emissions of sulfur dioxide and nitrogen oxides and other acid-causing substances have surpassed those of Europe and the United States, ranking first in the world. After Europe and North America, my country also has a large area of ​​acid rain distribution. Studies have shown that the forest area affected by acid rain in the seven southern provinces of my country is 128.21×104hm2. Due to the decline in forest growth, the annual economic loss caused by the decline in timber production has reached 600 million yuan; The economic loss of eco-benefits due to the decline of functions, the total annual loss is as high as 6 billion yuan.

[0003] Although there are many ways for acid rain to cause fo...

Examples

Embodiment 1

[0044] see figure 1 , a forest soil restoration method, comprising the following steps:

[0045] S1. First, take samples of the forest soil, conduct testing and analysis, and determine the degree of soil acidification;

[0046] S2. Take limestone ore and magnesite according to the degree of acidification, and pulverize the two to obtain repair powder;

[0047] S3, please refer to his 2-4, mix the repairing powder with the multi-antennary soil particle ball wrapped with earthworm larvae, make it adhere to the outer surface of the multi-antennary soil particle ball, and form a double-row repairing ball;

[0048] S4. Putting the double-row restoration balls on the acidified forest soil, and performing chemical restoration and biological restoration on the forest soil at the same time.

[0049] The temperature of the forest environment is 22-26°C when the restoration balls are placed in S3. At this temperature, it is suitable for the growth and development of earthworm larvae, t...
