Embodiment
[0032] The embodiment of the present invention provides a technology of a large hole tree planting combined with a biochar interlayer for saline-alkali geology, which includes the following steps:
[0033] S1. Modulation repair agent
[0034] Put the rice husk and corn stalk in the mixer, grind and stir them, crush them to form a powder, then add biochar to the powder, and stir, and finally, add gypsum powder to the powder, and stir, after the stirring is completed, set aside ;
[0035] S2. Land regulation
[0036] Ridge the land to be repaired, and turn up the soil in the lower layer to loosen the land and make it evenly distributed. After the turning is completed, sprinkle water to make the soil moist;
[0037] S3. Sprinkle repair agent
[0038] Sprinkle the prepared powder on the wet soil, and after the dispersion is completed, turn the soil to make the repair agent fully contact with the soil, so that the repair agent is evenly distributed in the soil;
[0039] S4. Moi...

The invention provides a technology for dealkalizing saline-alkali soil by combining large-hole tree planting with a charcoal interlayer, and relates to the technical field of land remediation. The technology for dealkalizing the saline-alkali soil by combining the large-hole tree planting with the biochar interlayer comprises the following steps: S1, preparing a remediation agent; S2, regularizing the soil; S3, dispersing the remediation agent; S4, wetting the soil, S5, drying the soil in the sun, S6, planting green plants, and S7, turning the soil at regular intervals. According to the technology, rice husks and corn straw are ground and crushed and are added into the remediation agent, so that moisture in soil can be absorbed and stored, the moisture of the soil is increased, and the treatment effect is improved; meanwhile, organic fertilizer and water are mixed and sprayed to the soil, after drying in the sun, the organic fertilizer can be locked through powder of the rice husks, the corn straw and biochar, and the fertilizer in the soil can be prevented from being lost while the land is treated; and by means of repeated soil turning, the fertilizer in the soil can be uniformly distributed, and the growth of elaeagnus angustifolia is promoted.
Description
technical field [0001] The invention relates to the technical field of land restoration, in particular to a technique for reducing alkalinity in saline-alkali geology by planting trees in large caves combined with biochar interlayers. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares, the formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive, and all kinds of saline-alkali soils are Formed under certain natural conditions, the essence of its formation is mainly the redistribution of various solubl...
