Problems solved by technology

[0006] The traditional method of improving soil pH value is to apply alkaline substances such as quicklime, plant ash, and dolomite powder, which can neutralize the active acid and exchangeable acid in the soil. However, if the nutrient structure is unbalanced, it is easy to cause problems such as soil compaction and soil flora imbalance.

preparation example Construction

[0035] The present invention also provides a kind of preparation method of above-mentioned soil conditioner, it comprises the following steps:

[0036] A. According to the corresponding ratio, put the shells in a high-temperature kiln for 6-15 minutes at 600°C-1200°C to make them melt completely, then take them out of the furnace to cool, crush them, and set them aside for use;

[0037] B. Put potassium feldspar, limestone, and dolomite in a high-temperature kiln at 1100°C-1500°C for 25-35 minutes in accordance with the corresponding proportions, make them all melt, and then take them out of the furnace to cool, pulverize, and set aside;

[0038] C. Fully mix the powders of step A and step B to obtain a soil conditioner.

[0039] If it is directly made into a powder, the powders in step A and step B can be passed through a 20-mesh sieve and then fully mixed. If it needs to be made into granules, pass the powders of step A and step B through a 100-mesh sieve and mix thoroughly...

Embodiment 1

[0042] For example, when powder is needed, shells: 400Kg, potassium feldspar: 200Kg, limestone: 200Kg, dolomite: 200Kg.

[0043] When it needs to be granular, shell: 400Kg, potassium feldspar: 200Kg, limestone: 200Kg, dolomite 195Kg, bentonite 3Kg, kaolin 2Kg.

[0044] The preparation method is as follows:

[0045] High-temperature calcination: 1) shells: place them in a high-temperature kiln at 600-1200°C for 6-15 minutes to calcine, make them all melt, then take them out of the furnace to cool, crush, and become semi-finished products for use;

[0046] 2) Potassium feldspar, limestone, and dolomite: put them in a high-temperature kiln for calcination at 1100-1500°C for 25-35 minutes, make them all melt, and then take them out of the furnace to cool, crush, and become semi-finished products for use;

[0047] Powder product: pass the powder obtained in 1) and 2) through a 20-mesh sieve respectively, then mix according to the proportion, inspect, measure, pack, and store for l...

specific Embodiment 2

[0054] Powder: shell: 500Kg, potassium feldspar: 100Kg, limestone: 300Kg, dolomite 100Kg.

[0055] Particles: shell: 500Kg, potassium feldspar: 100Kg, limestone: 195Kg, dolomite 100Kg, bentonite 2Kg, kaolin 3Kg.

[0056] The preparation method is as follows:

[0057] High-temperature calcination: 1) shells: place them in a high-temperature kiln at 600-1200°C for 6-15 minutes to calcine, make them all melt, then take them out of the furnace to cool, crush, and become semi-finished products for use;

[0058] 2) Potassium feldspar, limestone, and dolomite: put them in a high-temperature kiln for calcination at 1100-1500°C for 25-35 minutes, make them all melt, and then take them out of the furnace to cool, crush, and become semi-finished products for use;

[0059] Powder product: pass the powder obtained in 1) and 2) through a 20-mesh sieve respectively, then mix according to the proportion, inspect, measure, pack, and store for later use.

[0060] Granular product: pass the po...

Abstract

The invention discloses a soil conditioner for tobacco field acidic soil, wherein the soil conditioner comprises, by weight, 40-80 parts of shells, 20-60 parts of potassium feldspar, 10-50 parts of limestone, and 15-40 parts of dolomite. According to the present invention, the soil conditioner can neutralize the active acid and the exchangeable acid in the soil, obviously increase the pH value ofthe soil, increase the soil plough layer exchangeable Ca<2+> and Mg<2+> concentrations, improve the soil microbial environment, increase the numbers of soil bacteria, actinomycetes and aerobic cellulose decomposition bacteria, improve the activities of urease, acid phosphatase, catalase and cellulase, passivate the heavy metals in the soil, reduce the heavy metals in tobacco, reduce the occurrenceof tobacco root diseases, improve the aroma quality, the aroma amount and the concentration of tobacco leaves, and reduce the irritation, the miscellaneous gas and the like of tobacco leaves.

Description

technical field [0001] The invention relates to the field of soil conditioners, in particular to a soil conditioner for acidic soil in tobacco fields and a preparation method. Background technique [0002] Tobacco is an important economic crop and is widely planted all over the world. However, continuous cropping for many years has led to a drop in soil pH, severe acidification, a sharp decrease in soil nutrients, and aggravated tobacco root diseases, especially tobacco bacterial wilt. Affect the yield and quality of tobacco leaves, and the areas with severe disease even appear to be out of production. [0003] The most suitable pH range for the growth of high-quality flue-cured tobacco: 5.5 to 6.5. Studies have shown that soil acidification will have a greater impact on the content and activity of mineral nutrients such as nitrogen, phosphorus, potassium, aluminum, boron, iron and manganese, and heavy metal ions in the soil. The negative impact of the root system, thereby ...
