Method for improving soil property of tobacco field

Abstract

The invention relates to the technical field of soil improvement, in particular to a method for improving the soil property of a tobacco field. The method comprises steps as follows: (1) reconstruction of a soil plough layer of the tobacco field; (2) application of an organic material; (3) irrigation treatment; (4) application of base fertilizer; (5) application of additional fertilizer. With a reconstruction technology of the soil plough layer, 0-20 cm soil is interchanged with 20-40 cm soil in the tobacco field, then, a large quantity of organic materials are applied, water is irrigated, pyrroloquinoline quinone is applied in a matched manner, inorganic fertilizer, particularly, multiple different potash fertilizer is combined for application, accordingly, the content of organic matter in soil can be increased, the soil structural property can be improved, the bulk weight of the soil can be reduced, the soil porosity can be improved, and the soil acidity can be reduced. The dosage ofinorganic fertilizer in a conventional cultivation method can be reduced, the available nutrient, particularly, the content of available potassium, of the soil in the tobacco field is increased, thephysicochemical properties of the soil are improved, and the microbial activity of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving soil properties of tobacco fields. Background technique [0002] Flue-cured tobacco is one of the important economic crops in my country and occupies an important position in the national economy. Due to our country's large population and small land, the situation of grain and tobacco competition for land is severe, and the land in flue-cured tobacco planting areas is highly intensively used and the multiple cropping index is high. In production, there are still fertilization habits such as excessive chemical fertilizer application and low organic fertilizer application, which lead to poor soil quality. The organic matter content did not rise but fell, and the fertilizer utilization rate decreased year by year. The continuous increase in the amount of chemical fertilizers has destroyed the soil structure, shallowed the cultivated layer, decreased ...

Problems solved by technology

Due to our country's large population and small land, the situation of grain and tobacco competition for land is severe, and the land in flue-cured tobacco planting areas is highly intensively used and the multiple cropping index is high. In production, there are still fertilization habits such as excessive chemical fertilizer application and low organic fertilizer application, which lead to poor soil quality. decline, the organic matter content did not rise but fell, and the fertilizer utilization rate decreased year by year

The continuous increase in the amount of chemical fertilizers has destroyed the soil structure, shallowed the cultivated layer, decreased organic matter content, and reduced the quality of tobacco leaves. In some areas, problems such as soil acidification have occurred, and the types and quantities of beneficial microorganisms have decreased, which has greatly damaged the ecological environment of tobacco planting soil.
