Problems solved by technology

[0002] In view of the large amount of fertilizer used in agriculture, the low utilization rate, and the serious pollution caused by soil acidification, compaction, salinization, bacterial flora imbalance, and excessive heavy metals, etc., have led to a series of problems such as large-scale rotten roots and dead seedlings of crops, so The soil problem needs to be solved urgently
Generally, the improvement agents for acidified soil neutralize the soil by adding inorganic alkaline substances, which cannot solve the problem of soil microbial environment and soil structure improvement, and have no long-term effect

Embodiment 1

[0017] Embodiment 1, an acidifying soil improver, is made up of the raw material of following mass ratio: shell powder 30-60; Carboxymethyl cellulose 12-20; Polymethyl methacrylate 8-15; Calcium cyanamide 5-20; Nano silica solution 10-25. The invention uses shell powder as the main basic material, is suitable for acidifying soil, and has a pH value of 3.0-4.5. On cultivated land, 3-4 tons of soil conditioner is evenly sprinkled, and after 5-7 days, the field is raked and crops are planted.

Embodiment 2

[0018] Embodiment 2, in the acidifying soil conditioner described in embodiment 1: be made up of the raw material of following mass parts ratio: shell powder 30; Carboxymethyl cellulose 12; Polymethyl methacrylate 8; Calcium cyanamide 5 ; Nano silica solution 10 .

Embodiment 3

[0019] Embodiment 3, in the acidifying soil conditioner described in embodiment 1 or 2: be made up of the raw material of following mass parts ratio: shell powder 60; Carboxymethyl cellulose 20; Polymethyl methacrylate 15; Cyanamide Calcium 20; Nano silica solution 25.

Abstract

The invention relates to an acidified soil conditioner, which contains the following raw materials in parts by mass: 30-60 parts of shell powder, 12-20 parts of carboxymethyl cellulose, 8-15 parts of polymethyl methacrylate, 5-20 parts of calcium cyanamide, and 10-25 parts of nanosilicon dioxide solution. The shell powder is used as a soil structure conditioner, a certain amount of chemical components are added to regulate the pH value of the soil system and kill harmful bacteria in soil and maintain effective microbial community, so that the improvement of the soil structure, microbial environment and pH value can be achieved; in addition, the acidified soil conditioner can also provide essential calcium element and silicon element for soil, and can be effective for a long term after being applied once. The acidified soil conditioner not only achieves the acidified soil conditioning function, but also can improve the soil activity, increase trace elements, inhibit pathogenic bacteria of crops and improve the pH value of the acidified soil to achieve the effects of improving the soil microenvironment and improving the self restoration capability of soil, so that the yield and quality of crops can be remarkably improved.

Description

technical field [0001] The invention relates to a conditioner, in particular to an acidified soil conditioner. Background technique [0002] In view of the large amount of fertilizer used in agriculture, the low utilization rate, and the serious pollution caused by soil acidification, compaction, salinization, bacterial flora imbalance, and excessive heavy metals, etc., have led to a series of problems such as large-scale rotten roots and dead seedlings of crops, so The soil problem needs to be solved urgently. Generally, the improvement agents for acidified soil neutralize the soil by adding inorganic alkaline substances, which cannot solve the problem of soil microbial environment and soil structure improvement, and have no long-term effect. Contents of the invention [0003] The technical problem to be solved in the present invention is aimed at the deficiencies of the prior art, and proposes a method to improve soil activity, increase soil trace elements, inhibit crop...
