Problems solved by technology

At high pH, ​​it can also cause direct damage to plants by hydroxide ions
Some plants accumulate too much salt, which damages the protoplasm and seriously hinders the synthesis of proteins, which leads to the accumulation of nitrogen-containing intermediate metabolites, causing damage to cells.
3) Affect the normal nutrient absorption of plants: due to the competition of sodium ions, the absorption of potassium, phosphor

Embodiment 1

[0021] Put 295kg of natural acid rainwater into the 500L stirring tank, then slowly put in 20kg of urea, 20kg of copper sulfate, 20kg of ferric chloride, 30kg of ammonium chloride, 30kg of ferric sulfate and 40kg of boric acid, stir well, then put in 5kg of naphthaleneacetic acid and 8kg of vitamin C. 8kg of citric acid, 8kg of glacial acetic acid, 8kg of indole acetic acid and 8kg of orthotropin, stirred and mixed evenly to form the final product saline-alkali soil improvement agent. Dilute the above-mentioned medicament to 200mg / L, and evenly spray it on the saline-alkali land, and the spray dosage is 50g per square. Spray for the first time 5 days before planting crops, loosen the soil immediately after spraying, and then re-treat once every 2 days, a total of 2 treatments, start afforestation after the chemical treatment is completed, and make all the ground soil into similar Apple-shaped mounds (apple mounds), each apple mound length: width: height = 0.6: 0.8: 0.3 meters,...

Embodiment 2

[0023] Put 390kg of artificial acid rain into the 500L stirring tank, then slowly add 15kg of manganese sulfate, 10kg of aluminum chloride, 10kg of calcium nitrate, 10kg of zinc sulfate, 10kg of calcium phosphate, 15kg of magnesium sulfate and 10kg of boric acid, stir evenly, and then put in 5kg of humic acid Acid, 5kg naphthalene acetic acid, 5kg vitamin C, 5kg citric acid, 5kg indole acetic acid and 5kg stethogen, stir and mix evenly to form the final product saline-alkali soil improvement agent. Dilute the above-mentioned medicament to 300mg / L, and evenly spray it on the saline-alkali land, and the spray dosage is 60g per square. Spray for the first time 6 days before planting crops, loosen the soil immediately after spraying, and then re-treat once every 2 days, a total of 3 treatments, start afforestation after the chemical treatment, and make all the ground soil into similar Apple-shaped mounds (apple mounds), each apple mound length: width: height = 0.7: 0.9: 0.4 meters...

Embodiment 3

[0025] Put 200kg of natural acid rainwater and 110kg of artificial acid rainwater into the 500L stirred tank, then slowly put in 15kg of urea, 15kg of copper sulfate, 20kg of ferric chloride, 20kg of ammonium chloride, 10kg of ferric sulfate, 10kg of manganese sulfate, 10kg of aluminum chloride, 10kg calcium nitrate, 10kg zinc sulfate, 10kg calcium phosphate, 10kg magnesium sulfate and 10kg boric acid, stir evenly, then add 5kg humic acid, 5kg naphthalene acetic acid, 5kg vitamin C, 5kg citric acid, 5kg glacial acetic acid, 5kg indole acetic acid and 10kg Stir and mix uniformly to form the final product saline-alkali soil improvement agent. Dilute the above-mentioned medicament to 400mg / L, and evenly spray it on the saline-alkali land, and the spray dosage is 70g per square. Spray for the first time 7 days before planting crops, loosen the soil immediately after spraying, and then re-treat once every 2 days, a total of 3 treatments. Apple-shaped mounds (apple mounds), each ap...

Abstract

The invention relates to a saline-alkali soil improved medicament and a saline-alkali soil improved afforestation and soil preparation method, belonging to the technical field of saline-alkali soil improved technology; the saline-alkali soil improved medicament is composed of 55-85% of acid rain water, 12-36% of nutrient component and 3-11% of synergistic component; the saline-alkali soil improved afforestation and soil preparation method comprtises the following steps: diluting the saline-alkali soil improved medicament so as to spray to the saline-alkali soil evenly; starting a first spraying 5-8 days before planting crops; loosening soil at once after spraying the saline-alkali soil improved medicament; and carrying out the operation again each two days for 2-4 times; after spraying the saline-alkali soil improved medicament, starting to carrying out afforestation and soil preparation; and reforming ground oil into mounds like an apple shape, wherein tree seedlings are planted in concave positions of the middle of the apple-shaped mounds. According to the invention, alkalinity of soil of the saline-alkali soil is neutralized; decomposition of nutrient is accelerated; effectiveness of phosphorus is improved; problems of infertile soil, a poor structure, low nursery stock survival rate or difficult survival of the nursery stock are solved; and the saline-alkali soil improved afforestation and soil preparation method is characterized by simple and easy operation, low medicament production cost and excellent effect.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement methods, and specifically relates to a saline-alkali land improvement agent and a saline-alkali land improvement afforestation and soil preparation method. Background technique [0002] Saline-alkali land is a general term for various saline soils and alkaline soils, as well as salinized and alkalized soils to varying degrees. According to the incomplete statistics of UNESCO and FAO, the saline-alkali land area in the world is 954 million hectares, and our country is about 99 million hectares, including about 37 million hectares of modern saline-alkali soil, about 45 million hectares of residual saline-alkali soil, and 17 million hectares of potential saline-alkali soil million hectares. Saline-alkali land is a part of my country's important land resources. [0003] Saline-alkali soil is a kind of low-yield soil mainly caused by alkaline damage. It and saline soil are both...
