Embodiment 1

[0026] A cultivation method for reducing tobacco incidence and improving tobacco quality, comprising the following steps:

[0027] (1) Tobacco field finishing: clean up the tobacco stumps, carry out deep plowing and loosening of the soil with a powder ridge machine, and remove the soil from the soil surface to the soil depth of 40 cm;

[0028] (2) Prepare and apply organic materials: the organic materials include the following components in parts by weight: 40 parts of tobacco stalks, 40 parts of waste tobacco leaves, 10 parts of biochar, 30 parts of vermicompost, 10 parts of decomposed cow dung, onion 20 parts of skin, 10 parts of mustard leaves, 15 parts of leek residue, 5 parts of biogas residue and 20 parts of potassium humate, respectively apply the above-mentioned organic materials in three soil layers of 40cm, 20cm and soil surface. The ratio of organic material application rate is 1:1:1, and the total application rate of organic material is 750kg / mu. After the lower tw...

Embodiment 2

[0034] A cultivation method for reducing tobacco incidence and improving tobacco quality, comprising the following steps:

[0035] (1) Tobacco field finishing: clean up the tobacco stumps, carry out deep plowing and loose plowing of the soil with a powder ridge machine, and remove the soil from the soil surface to the soil depth of 50 cm;

[0036] (2) Prepare and apply organic materials: the organic materials include the following components in parts by weight: 60 parts of tobacco stalks, 30 parts of waste tobacco leaves, 20 parts of biochar, 20 parts of vermicompost, 15 parts of decomposed cow dung, onion 15 parts of bark, 15 parts of mustard leaves, 10 parts of leek residue, 10 parts of biogas residue and 15 parts of potassium humate. Apply the above-mentioned organic materials in the three soil layers of 50cm, 25cm and soil surface respectively. The application rate of organic materials is 1:2:1, and the total application rate of organic materials is 500kg / mu. After the lower...

Embodiment 3

[0042] A cultivation method for reducing tobacco incidence and improving tobacco quality, comprising the following steps:

[0043] (1) Tobacco field finishing: clean up the tobacco stumps, carry out deep plowing and loosening of the soil with a powder ridge machine, and remove the soil from the soil surface to the soil depth of 60 cm;

Abstract

The invention relates to the technical field of agricultural planting, in particular to a cultivation method for decreasing the tobacco incidence rate and improving the tobacco quality. The cultivation method for decreasing the tobacco incidence rate and improving the tobacco quality comprises the following steps that (1) tobacco field preparation is conducted; (2) organic materials are prepared and applied; (3) waterflooding and film-coating treatment is conducted; (4) base fertilizer is applied to the whole land; (5) planting and transplanting are conducted; and (6) top application is conducted. According to the cultivation method for decreasing the tobacco incidence rate and improving the tobacco quality, organic material applying, waterflooding and film-coating treatment are conductedon the tobacco field in the cultivation process, parts of soil pathogens can be directly killed through organic acid caused by anaerobic fermentation of the organic materials, and the tobacco incidence rate is reduced; the soil hardening level can further be improved after the organic materials are applied, weeds are decreased, and tobacco field soil nutrient material content is increased, thus the problems that the disease resistance of the tobacco is decreased due to soil degradation, and tobacco disease occurs frequently due to the fact that the cardinal number of pathogenic bacteria in weeds and soil and pests such as root-knot nematode is large are reduced, and the incidence rate of common diseases of the tobacco is remarkably reduced while the quality of the tobacco can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method for reducing the incidence of tobacco and improving the quality of tobacco. 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, the land in flue-cured tobacco planting areas is highly intensively used and the multiple cropping index is high, and there are still fertilization habits such as excessive chemical fertilizer application and low organic fertilizer application during the cultivation process, resulting in tobacco Diseases frequently occur, and the quality of tobacco is difficult to improve. In traditional tobacco cultivation methods, the soil has not been deeply loosened for many years, and the cultivated laye...
