Problems solved by technology

Most of the existing technical methods for acidic soil improvement are single use of lime. Although this method can achieve acid-base neutralization effect to a certain extent, it is not very obvious for improving the yield and quality of tobacco leaves; while other soil improvers There is a problem of high cost

Embodiment 1

[0014] Taking 5 mu of acidic tobacco-growing soil as a unit, the acidic tobacco-growing soil improver is obtained after 200 kg of slaked lime and 5 kg of polyacrylamide are uniformly mixed. The method of using the agent comprises the following steps:

[0015] (1) Site selection:

[0016] Choose acidic tobacco-growing soil with a pH value of 4.0-5.0, without serious soil-borne diseases or sporadic diseases;

[0017] (2) Spreading:

[0018] The amount of soil improver is 80kg / mu, and it is applied on the surface before the tobacco land preparation, and strives to spread it evenly as much as possible;

[0019] (3) Flue-cured tobacco planting

[0020] Measures such as arable land, fertilization, transplanting and field management were carried out in accordance with conventional flue-cured tobacco planting methods.

[0021]

Embodiment 2

[0023] Taking 5 mu of acidic tobacco-growing soil as a unit, the acidic tobacco-growing soil improver is obtained after 300 kg of slaked lime and 20 kg of polyacrylamide are uniformly mixed, and the method of using the agent comprises the following steps:

[0024] (1) Site selection:

[0025] Choose acidic tobacco-growing soil with a pH value of 5.0-5.5, without serious soil-borne diseases or sporadic diseases;

[0026] (2) Spreading:

[0027] The dosage of soil improver is 60kg / mu, and it is applied on the surface before the tobacco land preparation, and strives to spread it evenly as much as possible;

[0028] (3) Flue-cured tobacco planting

[0029] Measures such as arable land, fertilization, transplanting and field management were carried out in accordance with conventional flue-cured tobacco planting methods.

Embodiment 3

[0031] Taking 5 mu of acidic tobacco-growing soil as a unit, the acidic tobacco-growing soil improver is obtained after 280 kg of slaked lime and 10 kg of polyacrylamide are evenly mixed, and the method of using the agent comprises the following steps:

[0032] (1) Site selection:

[0033] Choose acidic tobacco-growing soil with a pH value of 5.5-6.0, without serious soil-borne diseases or sporadic diseases;

[0034] (2) Spreading:

[0035] The amount of soil improver is 40kg / mu, and it is spread on the surface before the tobacco land preparation, and strives to spread it evenly as much as possible;

[0036] (3) Flue-cured tobacco planting

[0037] Measures such as arable land, fertilization, transplanting and field management were carried out in accordance with conventional flue-cured tobacco planting methods.

Abstract

The invention relates to an acid tobacco-planting soil conditioner and an application method thereof. The acid tobacco-planting soil conditioner is prepared by mixing the following raw materials in parts by weight: 20-30 parts of slaked lime and 0.5-2 parts of PAM (industrial polyacrylamide). The acid tobacco-planting soil conditioner changes the acid tobacco-planting soil, the originally fixed nutrition ions are released, and the released nutrition ions can be absorbed by aggregates formed by PAM, thus nutrient loss in the soil can be reduced, the nutrition ions which are aggregated into acid soil particles and can not be absorbed by roots of flue-cured tobaccos are absorbed as the environment is changed, tobacco seedling growth can be obviously promoted, the tobacco leaf yield can be improved, a vigorous plant inhibits diseases of flue-cured tobacco, especially bacterial wilt, and further the quality and yield of the flue-cured tobacco are improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an acidic tobacco planting soil improver and its application method. Background technique [0002] Tobacco planting soil in Guizhou has long-term one-sided attention to chemical fertilizers, resulting in a sharp drop in soil organic matter content, deterioration of soil physical properties, especially the decline in the number and quality of aggregates, and degradation of soil aeration, resulting in a drop in soil pH; at the same time, acidic soil particles are fixed. There are a large amount of nutrient ions needed by flue-cured tobacco, but in an acidic environment, these nutrient ions cannot be absorbed by the root system of flue-cured tobacco, which seriously affects the growth of tobacco leaves. Therefore, the application of soil amendments is one of the important measures to repair acidified soil. Wu Zengfang reported that soil amendments can effectively improve s...
