Problems solved by technology

In order to reduce the pH value of saline-alkali land, some acidic substances are usually added to the soil conditioner to neutralize the alkaline substances in saline-alkali land. Usually, acidic substances can be divided into inorganic acids and organic acids. Inorganic acids have strong acidity, although they are in In the short term, it has a good neutralizing effect on the alkaline substances in the soil, but after the addition of inorganic acids, it will cause rapid changes in the acidity and alkalinity of the soil, and the effect is not sustainable, while organic acids have good buffering properties performance, so it is more suitable for soil improvement

preparation example 2

[0037] Preparation Example 2 of Bamboo Vinegar: 1. after crushing and sieving bamboo waste materials, coarse bamboo powder with a fineness of 40-60 meshes was obtained; 2. carbonizing the coarse bamboo powder at a temperature of 350° C. The smog that produces in the coarse bamboo powder carbonization process, after the smog is cooled, obtains crude bamboo vinegar; 3. add 3% 2-hydroxypropionic acid and the weight of crude bamboo vinegar in crude bamboo vinegar The 1% L-malic acid of the weight of crude bamboo vinegar liquid, at the temperature of 45 ℃, insulation 4h, then be warming up to 160 ℃, collect distillation product, obtain bamboo vinegar liquid, remaining solid matter is bamboo charcoal powder.

preparation example 3

[0038] Preparation Example 3 of Bamboo Vinegar: 1. after crushing and sieving bamboo waste materials, coarse bamboo powder with a fineness of 40-60 meshes was obtained; 2. carbonizing the coarse bamboo powder at a temperature of 400° C. The smog that produces in the coarse bamboo powder carbonization process, after the smog is cooled, obtains crude bamboo vinegar; 3. add 3% 2-hydroxypropionic acid and the weight of crude bamboo vinegar in crude bamboo vinegar The 1% L-malic acid of the weight of crude bamboo vinegar liquid, at the temperature of 50 ℃, insulation 5h, then be warming up to 170 ℃, collect distillation product, obtain bamboo vinegar liquid, remaining solid matter is bamboo charcoal powder.

preparation example 4

[0039] Preparation Example 4 of Bamboo Vinegar Liquid: The difference between this preparation example and Preparation Example 1 of bamboo vinegar liquid lies in that step ③ does not contain 2-hydroxypropionic acid and L-malic acid.

[0040] 2. Preparation example of amino acid compound solution Preparation example 1 of amino acid compound solution: take discarded shells, shrimp shells, crab shells, and fish bones, clean them, dry, pulverize and sieve to obtain shells with a fineness of 40-60 mesh powder; add 20% of the weight of the shell powder bamboo vinegar and 5% of the phosphoric acid of the shell powder to the shell powder, heat up to 80°C, stir and hydrolyze for 16 hours, separate the solid from the liquid, and collect the liquid to be the amino acid compound liquid. The remainder is shell residue.

Abstract

The invention discloses a soil conditioner for regulating salinity and a preparation method thereof. The key point of the technical scheme is a soil conditioner for regulating salinity, which comprises the following components in parts by weight: bamboo vinegar liquid 100 ‑150 parts, 20‑30 parts of amino acid compound liquid, 50‑60 parts of plant fermented fertilizer, 10‑20 parts of animal organic fertilizer and 1‑3 parts of biological agent. The present invention uses the bamboo vinegar extracted from bamboo waste as the main raw material, and can increase the permeability of the soil and reduce the pH value and salinity of the soil by cooperating with the amino acid compound liquid, plant fermented fertilizer, animal organic fertilizer and biological bacteria agent. Increase the release of organic matter in the soil, increase the fertility, and at the same time increase the activity of magnesium ions and calcium ions in the soil, and improve the absorption and utilization of nutrients in the soil by plants.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improver, more specifically, it relates to a soil improver for regulating salinity and a preparation method thereof. Background technique [0002] Soil improver, also known as soil conditioner, is a material that is mainly used to improve the physical, chemical and biological properties of soil to make it more suitable for plant growth, rather than mainly providing plant nutrients. Because soil improvers have good effects in improving soil physical and chemical properties, increasing soil ion exchange rate, etc., soil improvers are widely used in the treatment of saline-alkali land. The main characteristics of saline-alkali land are high water-soluble salt and alkaline substances, low soil organic matter content, poor aggregate structure, few varieties available on saline-alkali land, low yield, and poor efficiency, which have always restricted the development of agricultural planting. ...
