Problems solved by technology

However, the acidic sulfate soil conditioner cannot improve the deep acidic soil. With the passage of time and the shower of rain, the soil will be re-acidified after the acid-improving substances are consumed, and there are a small amount of heavy metals such as lead, cadmium, and arsenic in the fly ash Elements, long-term use will cause secondary pollution, and transporting zeolite consumes manpower, material and financial resources

Embodiment 1

[0040] Embodiment one: a ferrous sulfide type acid soil improvement and bare land vegetation recovery method: its steps include: (1) soil general survey: respectively in the gravel field of highland area, low-lying land area, transitional zone area that need to improve land , sandy land, and bare land, the depth of the soil is 20cm, and the pH value is measured after mixing. The soil pH value is measured by litmus paper or color plate quick test method, or by water immersion method, litmus paper, Color guide quick test method and water immersion method are existing measuring methods;

[0041] (2) Soil classification: According to the soil properties and pH value of step (1), the soil is divided into three categories: sandy soil, red irony soil, and black irony soil, wherein the pH value of sandy soil is more than 3.56, and the red irony soil The pH value of the soil is 3.00-3.50, and the pH value of the black iron soil is below 3.00;

[0042] (3) determine quicklime consumpti...

Embodiment 2

[0058] Embodiment two: the difference between this embodiment and embodiment one is:

[0059] (7) Planting plants: select the plants cultivated in the step (5) to be planted on the improved land, when planting, adopt the bag seedling raising and transplanting method, and mix the leguminous and gramineous plants, and improve in the step (6) Holes were dug on the land to be planted, and wedelia, ciliated duckbill, and teff were transplanted out of bags in different caves, and then the excavated debris was covered around the caves and pressed. Then plant one or more of lentils, wing beans, and stylo around the cave, and add bahia grass appropriately;

[0060] Laying grass blankets on the gravel ground to be planted and the light floor to be improved, the grass blankets are the grass blanket bricks that the size of the Ayursia chinensis and the false thrift grass cultivated by the bag seedlings of step (5) are respectively planted into specifications of more than 30cm*30cm, and th...

Embodiment 3

[0062] Embodiment three: the difference between this embodiment and implementation one is:

[0063] (7) Planting plants: select the plants cultivated in the step (5) to be planted on the improved land, when planting, adopt the bag seedling raising and transplanting method, and mix the leguminous and gramineous plants, and improve in the step (6) Dig caves on the land to be planted, and transplant paspalum, imperata, and crabgrass into different caves, and then cover the excavated debris around the caves and compact them, and then plant them in the caves. Plant one or more of chain pods, wing beans, and stylo around the surrounding area, and add bahia grass appropriately;

[0064] On the improved gravel ground to be planted and the bare floor, the grass blanket is laid. The grass blanket is that the honey grass and the false thrift grass cultivated by step (5) bag seedlings are respectively planted into the grass blanket bricks whose specifications are more than 30cm*30cm. The...

Abstract

The invention discloses a ferrous sulfide acid soil improvement and bare land vegetation recovery method. The method comprises the following steps of 1, general survey of soil; 2, soil classification;3, determination of the usage amount of quicklime; 4, digging of pits in a to-be-improved land area; 5, screening of local territory plants, acid-resistance plants and accompanying plants; 6, soil improvement, wherein the pits are filled with organic matter, and then the quicklime with the usage amount specified in step 3 is uniformly scattered in the pits, drainage ditches and non-dug land; 7, soil compaction; 8, planting of the plants; 9, planting of the accompanying plants; 10, land fertility improvement; 11, secondary planting for densifying plants. By means of the ferrous sulfide acid soil improvement and bare land vegetation recovery method, re-acidification of soil can be prevented so that the improved soil can have multiple purposes.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a ferrous sulfide type acid soil improvement and bare land vegetation restoration method. Background technique [0002] With the continuous expansion of cities and increasing population, the problem of land shortage is becoming more and more serious. Therefore, improving various lands that are not suitable for living needs has become an urgent task to solve land pressure. Nowadays, more and more excavation and filling have caused a lot of soil that does not belong to the local area to enter the city and integrate into life; more and more mines have caused large-scale land pollution and waste due to improper construction in the early years, and saving the land has become an urgent matter. . Acidic soil is the general term for soil with a pH value less than 7. Including brick red soil, red soil, red soil, yellow soil and dry red soil and other soil types. In the t...
