Problems solved by technology

There are also chemical amendments, such as lime, fly ash and other industrial by-products, which are used in soil acidification improvement, but the disadvantages of single chemical amendments are becoming increasingly apparent
For example, the single application of lime in acidic soil has a significant short-term improvement effect, but long-term application will cause double acidification, and it will also cause soil structure and fertility to decline, forming a "lime board field".
In addition, industrial by-product amendments may contain heavy metal ions, which will increase the risk of accumulation of heavy metal ions to varying degrees during the process of improving acidic soil

Embodiment example 1

[0022] The experiment was carried out in the tobacco field of Huangdu Township, Xuancheng City, Anhui Province, and the representative acidified soil (pH 5.45) with the same soil texture and similar fertility was selected. The variety of flue-cured tobacco is Yunyan 97, the main local variety. The rice variety to be planted later is Wandao 129. According to the proportion of different groups of soil acidity improvers (quicklime, dolomite powder, bio-black carbon and silicon-calcium powder), the improvement effect of soil acidification is designed as follows. There are 4 treatments in this experiment, the details are as follows, CK is the one without acidification improver In comparison, T1 is the improver formula 1 (all quicklime), T2 is the improver formula 2 (20 parts of dolomite, 10 parts of quicklime), T3 is the improver formula 3 (20 parts of dolomite, 10 parts of quicklime, 10 parts of biological black carbon parts), T4 is improver formula 4 (20 parts of dolomite, 10 pa...

test example 2

[0029] The experiment was carried out in the tobacco field of Yangliu Town, Xuancheng City, Anhui Province, and the representative acidified soil (pH 6.0) with the same soil texture and similar fertility was selected. The variety of flue-cured tobacco is Yunyan 97, the main local variety. The experiment was designed according to different formulations and proportions of soil acidification amendments (quicklime, dolomite powder, straw bio-black carbon and silicon-calcium powder). A total of 4 treatments were set up in the test, specifically: CK was the control (no acidifying modifier), T1 was the modifier formula 1 (20 parts of dolomite, 10 parts of quicklime), T2 was the modifier formula 2 (20 parts of dolomite, 20 parts of quicklime, 10 parts of bio-black carbon), T3 is improver formula 3 (20 parts of dolomite, 10 parts of quicklime, 10 parts of bio-black carbon, 10 parts of silicon-calcium powder). The dosage is 1500kg / hm 2 . The experiment was repeated 3 times for each t...

Abstract

Belonging to the technical field of acidified soil treatment and remediation, the invention provides a nutritional type tobacco field soil acidification modifier formula and a use method thereof. The nutritional type tobacco field soil acidification modifier formula is formed by mixing of dolomite powder, quicklime, biological black charcoal and silicon-calcium powder in proportion. The use method consists of: firstly before ridging of tobacco field farmland, employing 5-point mixing sampling, then analyzing the acid-base property of soil, if the acidification degree is high and improvement is needed, spreading the nutritional type soil acidification modifier on the tobacco field surface before farming and ridging of the tobacco field, and then ploughing the mixture evenly, with the specific dosage and continuous usage time being determined by the soil acidification severity. According to the nutritional type tobacco field soil acidification modifier formula and the use method provided by the invention, the design and formula are reasonable, the use method is appropriate, the tobacco field soil acidification status can be improved significantly, and the tobacco development and disease resistance can be promoted, and the yield and quality of cured tobacco are improved. In addition, the formula and the method also have good effects in improving the stress resistance and yield of afterculture paddy rice.

Description

technical field [0001] The invention belongs to the technical field of acidified soil control and restoration, and in particular relates to a formula of a nutritional tobacco field soil acidified improver and a method for using the same. Background technique [0002] Studies have shown that the area of ​​acidic soil (pH<5.5) in my country has risen from 7% 30 years ago to 18% at present. In 14 southern provinces (autonomous regions and municipalities), the percentage of areas with soil pH<5.5 has expanded from 20% to 40%, and the proportion of soil with pH<4.5 has expanded from 1% to 4%. According to the results of the national tobacco balanced fertilization census, the pH value of most of the main tobacco-growing soils in my country is lower than the pH value (5.5-6.5) that is optimal for tobacco growth, especially in the southern tobacco-growing areas. Soil acidification directly affects the transformation of soil nutrients and microbial environment and activity,...
