Example Embodiment

[0013] Example 1:

[0014] Taking 5 acres of acid tobacco planting soil as a unit, the acid tobacco planting soil conditioner is prepared by uniformly mixing 200 kg of slaked lime and 5 kg of polyacrylamide. The method of using the agent includes 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 dosage of the soil amendment is 80kg / mu, and it shall be sprayed on the surface before the tobacco field preparation, and shall be applied as evenly as possible;

[0019] (3) Flue-cured tobacco planting

[0020] Cultivated land, fertilization, transplanting and field management are carried out in accordance with conventional flue-cured tobacco planting methods.

[0021]

Example Embodiment

[0022] Example 2:

[0023] Taking 5 acres of acid tobacco planting soil as a unit, the acid tobacco planting soil conditioner is prepared by uniformly mixing 300 kg of slaked lime and 20 kg of polyacrylamide. The method of use of the agent includes 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 amendment is 60kg / mu, and it shall be sprayed on the surface before site preparation, and shall be applied as evenly as possible;

[0028] (3) Flue-cured tobacco planting

[0029] Cultivated land, fertilization, transplanting and field management are carried out in accordance with conventional flue-cured tobacco planting methods.

Example Embodiment

[0030] Example 3:

[0031] Taking 5 acres of acid tobacco planting soil as a unit, the acid tobacco planting soil conditioner is prepared by uniformly mixing 280 kg of hydrated lime and 10 kg of polyacrylamide. The method of use of the agent includes 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 amendment is 40kg / mu. Spread on the surface of the tobacco field before site preparation, and try to spread it as evenly as possible;

[0036] (3) Flue-cured tobacco planting

[0037] Cultivated land, fertilization, transplanting and field management are 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...
