Abstract
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...
