Embodiment Construction

[0014] Hereinafter, the present invention will be further described with examples, but it is not limited to any one of these examples or similar examples.

[0015] Fermentation of Artificial Biomatrix

[0016] 1. First crush the corn stalks, and spread out the wet cow dung and dry it for later use.

[0017] 2. Build piles on cement or brick pavement: lay the crushed corn stalks with a thickness of 20cm and a width of 1.8m on the bottom layer, and then spread cow dung with a thickness of 10cm, and add water to moisten it, and control the humidity to 70% (holding without continuous water droplets) dripping, it can disperse naturally after opening). Spread corn stalks and cow dung according to this thickness. When the height of the pile is 1.5 meters, arrange the surroundings of the pile to make it into a trapezoid (horse head base shape) and then complete the pile.

[0018] 3. Turn over the pile every 7 days after building the pile. It is required to turn over the unfermented...

Abstract

The invention discloses a method for afforesting an artificial forest by closely planting trees on an in-situ repaired saline land with improved great holes. In order to afforest the artificial forest by closely planting trees, firstly, the saline land is prepared with holes dug, and then the eluvial soil dug out for land preparation is mixed with an artificial biological matrix prepared by curing corn stalks and cow dung to prepare the standby artificial improved soil. A layer of corn stalks is spread on the bottom of the holes, then a layer of cow dung is added to the corn stalks, and successively a layer of corn stalks is spread on the cow dung. Then the artificially improved soil is applied to the holes, and a saline alkali soil amendment is poured on the artificially improved soil. After selected seedlings are planted in the holes, the artificially improved soil is used for fixing root systems and water is irrigated to the soil. Finally, the artificially improved soil is stacked on the planting holes until a trapezium shape is formed, and a surface soil film former is spread on the artificially improved soil. A perforated feeding channel is dug between every two holes, and isfilled with the artificially improved soil.

Description

Technical field: [0001] The invention relates to a three-layer structure of crushed corn stalks + cow dung + crushed corn stalks and artificially improved soil, an in-situ repair method, application of a salt-alkali reducing agent, and spraying of a surface soil film-forming agent, and is mainly used for improving soil physical and chemical structures. Background technique: [0002] The total amount of saline-alkali land resources in my country is about 9913×10 4 hm 2 , of which the modern saline-alkali soil area is 3693×10 4 hm 2 , the residual saline-alkali soil is about 4487×10 4 hm 2 , and there are about 1733×10 4 hm 2 Potential saline-alkali soils are mainly distributed in the inland areas of Northeast China, North China, and Northwest China, as well as the coastal areas north of the Yangtze River, in a total of 23 provinces, municipalities, and autonomous regions. Among them, the distribution in the Northeast is about 2 million hm 2 , mainly soda-alkali saline...
