Improvement of alkaline soil to achieve what to use

Camellias, rhododendrons, gardenias, smiles, Milanese, jasmine and other flowers that prefer acidic soils grow poorly in alkaline soils and die.

The most fundamental way to prevent and control the damage of strong alkaline soil to flowers is to carry out soil improvement. Alkaline soils can be improved by adding coniferous soils. Coniferous soil is made from the needles and stumps of decaying pines and cypresses, and is highly acidic.

The general alkaline soil is mixed with 1 5 or 1 6 coniferous soil, which is suitable for acid-loving flower pots. or 100 200 grams of sulfur powder mixed into 1 cubic clay for a period of 2 3 years.

For potting soil with pH greater than 7, it can also be watered with 150 200 times vinegar solution, watered once every 15 20 days, or add 250 350 times of water before 8 o'clock in the morning, or spray the leaf surface after 5 o'clock in the afternoon, spray once every 10 days, and make the leaves turn from yellow to green for 3 or 4 times in a row. When using vinegar, it should be noted that the vinegar used must be edible rice vinegar, not industrial chemical vinegar; It must be sprayed in the morning or evening to avoid the evaporation of acetic acid and its failure; It must be used in combination with other fertilizers.

Gypsum can be applied, and chemical fertilizer is acidic fertilizer, but this method is fast, but it will make the soil compact, and it is best to apply organic fertilizer when using this method.

mgcl2.Strong acids and weak bases are acidic salts. to neutralize alkaline soils.

Diammonium phosphate or superphosphate are used for alkaline soil improvement methods.

In the selection of fertilizers and fertilizers. To consider the alkaline characteristics of the soil, attention should be paid to the preferential use of diammonium phosphate or superphosphate. Because the application of calcium, magnesium, phosphate fertilizer or phosphate rock powder on alkaline soil is basically ineffective.

The use of diammonium phosphate and superphosphate is very good, and diammonium phosphate is granular, which is conducive to improving the available phosphorus content of soil.

Soil with high phosphorus content was applied with superphosphate, which contains a certain amount of sulfuric acid, which is conducive to the activation of soil active components.

Alkaline soil improvement measures:

Biological measures are generally considered to be the most effective way to improve saline-alkali land. The introduction of salt-tolerant and salt-washing plants can use plants to drain salt. For example, the willow has a strong tolerance for chloride and other salts.

The structure of the salt glands and pores of the plant itself can take away a large amount of coarse salt from the soil, increase the coverage rate of plants, reduce ground evaporation, and reduce the accumulation of salt.

The application of organic matter to saline-alkali soils is also a typical biological improvement method, which has been widely reported. By cultivating the soil, applying organic fertilizer, and cultivating the fertile layer of desalination fertilizer, the physical and chemical properties of the soil can be improved, and the soil desalination can be accelerated, so as to achieve sustainable development.

The methods for improving alkaline soils are as follows:

1. Use acidic fertilizers, such as sulfuric acid such as ammonium, ammonium nitrate, ammonium chloride, superphosphate, potassium dihydrogen phosphate, potassium sulfate, etc., to neutralize alkali acorns.

2. Plant alkali-tolerant crops, such as cotton, leguminous crops, hemp, underground fruiting crops, wheat, etc., and transform them while utilizing.

3. Deepen the deep layer, reduce the water level, and wash the alkali year by year.

4. Apply more farm fertilizer, improve the soil, cultivate soil fertility, and enhance the affinity of the soil.

Methods for improving alkaline soils include the addition of organic matter, acidifiers, alkaline soil conditioners, targeted fertilizers, and good irrigation management.

1. Applying a large amount of organic matter (such as rotting compost, straw, wood chips, etc.) can improve the structure and fertility of alkaline soil. Organic matter provides nutrients, increases soil water retention, and improves soil aeration and drainage.

2. The use of acidifiers can reduce the pH value of the soil, thereby reducing the alkalinity of the alkaline soil. Common acidifiers include iron sulfate, aluminum sulfate, etc. When applying acidifiers, it is necessary to pay attention to the dosage and the application of the dosage method to avoid causing damage to the plant and soil environment.

3. Some special alkaline soil conditioners can neutralize alkaline ions in the soil and reduce the alkalinity of the soil. These regulators typically contain acids or salts that can alter the pH of the soil and thus mitigate the effects of alkaline soils.

4. When planting crops, you can choose fertilizers suitable for alkaline soil or residual soil. Some fertilizer formulations are leaked with ingredients that fight alkaline soils, which can provide the nutrients needed by plants and help them better adapt to alkaline environments.

5. Reasonable irrigation management can help alleviate the problem of alkaline soil. Avoid over-irrigation and ensure that the soil is well drained to prevent the accumulation of salts and alkaline substances in the soil.

Kilograms of ferrous sulfate can be applied to open field flowers per 10 square meters, and the pH value of the unit can be reduced after application; For clay heavy soils, the dosage can be increased by 1 3. x0d x0a application of vinegar solution: the vinegar applied must be edible rice vinegar, for potting soil with a pH value greater than 7, it can be watered with 150 2004 tone vinegar solution, once every 15 20 days.

The application of coniferous soil is the most fundamental method for improving alkaline soil. Coniferous soil is made from rotten pine and cypress needles, dead branches and other litter, sawdust, etc., and is highly acidic. Generally, alkaline soil mixed with 1 5 or 1 6 coniferous soil, that is, suitable for acid-loving flower potted use, the above is the introduction of how to improve alkaline soil.

Summary. Dear, I'm an assistant. You can apply well-rotted manure, peat, sawdust, edible acid fertilizers such as lead sulfate, ferrous sulfate, sulfur powder, ammonium sulfate, ammonium nitrate, ammonium chloride, superphosphate, potassium dihydrogen phosphate, potassium sulfate, etc., to neutralize alkaline in a directional manner.

Dear, I'm an assistant. You can apply well-rotted manure, peat, sawdust, edible acid fertilizers, such as lead sulfate, ferrous thioduanate, sulfur powder, ammonium sulfate, ammonium nitrate, ammonium chloride, superphosphate, potassium dihydrogen phosphate, potassium sulfate, etc., to neutralize alkalinity.

If it is a flower potted plant, you can apply vinegar: the vinegar applied must be edible rice vinegar, for potting soil with a pH value greater than 7, you can use 150 2004 tone vinegar to irrigate, once every 15 20 days.
