Problems solved by technology

[0005] The use of soil exposure or flooding can reduce the occurrence of soil-borne diseases and insect pests to a certain extent, but it has certain limitations and disadvantages such as long treatment time and unstable effect.
Soil disinfection by fumigation with soil chemical reagents can effectively kill pathogenic bacteria and nematodes in the soil, but it is easy to cause chemical reagents to remain in the soil, pollute the environment, endanger the health of humans and animals, and seriously reduce the yield and quality of crops

Embodiment 1

[0063] Example 1: Using different organic materials to carry out ecological control of soil-borne diseases in tobacco fields

[0064] The implementation steps of this embodiment are as follows:

[0065] A. Tobacco Field Soil Treatment

[0066] Plow the soil of the tobacco field with a plowing depth of 20-25cm to make the soil loose and smooth, and at the same time remove the remaining animal and plant residues in the soil of the tobacco field;

[0067] B. Add organic materials

[0068] According to 1.5kg / m 2 The amount of addition is to add the 100-mesh corn stalk, decomposed pig manure and the organic material of the purple vetch to the tobacco field soil treated in step A, and then fully mix evenly;

[0069] C. Irrigation

[0070] Irrigate in the tobacco field soil containing organic materials obtained in step B, and the amount of irrigation water reaches the saturated water content of the soil;

[0071] D. Laminating

[0072] Cover the irrigated tobacco field soil wit...

Embodiment 2

[0081] Example 2: Ecological control of soil-borne diseases in tobacco fields using different irrigation volumes

[0082] The implementation steps of this embodiment are as follows:

[0083] A. Tobacco Field Soil Treatment

[0084] Plow the soil of the tobacco field with a plowing depth of 20-25cm to make the soil loose and smooth, and at the same time remove the remaining animal and plant residues in the soil of the tobacco field;

[0085] B. Add organic materials

[0086] According to 1.5kg / m 2 The amount of addition is to add the organic material of corn stalks with a particle size of 100 meshes to the tobacco field soil treated in step A, and then fully mix evenly;

[0087] C. Irrigation

[0088] Irrigate the tobacco field soil containing organic materials obtained in step B, and the amount of irrigation water reaches 80% of the field water capacity of the soil, the field water capacity of the soil or the saturated water content of the soil;

[0089] D. Laminating

Abstract

The invention relates to an ecological prevention and treatment method for soil-borne diseases in a tobacco field. The method comprises the following steps: treatment of soil in the tobacco field, addition of organic materials, water irrigation, film mulching, etc. The method provided by the invention can kill soil pathogenic fungi, bacteria or nematodes capable of causing plant diseases without application of any chemical agents, also can improve the yield and quality of a crop, and has short processing time and strong popularizing value.

Description

【Technical field】 [0001] The invention belongs to the technical field of flue-cured tobacco production. More specifically, the present invention relates to an ecological control method for soil-borne diseases in tobacco fields. 【Background technique】 [0002] With the increasing degree of agricultural intensification and multiple cropping index in my country, soil continuous cropping obstacles are becoming more and more serious, mainly manifested in soil compaction, soil acidification, soil secondary salinization and soil-borne diseases, which are frequently and increasingly serious. As far as flue-cured tobacco production is concerned, tobacco root black rot, bacterial wilt, and black shank are several devastating diseases that restrict tobacco production and bring huge losses to tobacco production. Tobacco root-knot nematode disease can generally cause a 10-20% reduction in production, and can reach 30-40% in severe cases, or even extinction. According to the survey of 1...
