Embodiment example

[0026] The planting mode is constructed by combining the natural fragrance source plant-geranium geranium and flue-cured tobacco, with 4 soil for each planting, 12 soil for adjacent planting of flue-cured tobacco, and a distance of 1.2m between adjacent rows. 100 mu of flue-cured tobacco red was cultivated in a continuous patch 500 meters away from the biome as a control, and three repetitions were set for each treatment. Disease investigation and severity grading standards are in accordance with GB / T 23222-2008. Conduct systematic investigation: From the beginning of the group tree period to the harvest period, take samples at 5 fixed points in the field, with no less than 30 plants at each point, and calculate the incidence rate and disease index. Grade 0: The whole plant is disease-free. Grade 1: Heart leaves with bright veins or slightly mosaic leaves, no obvious dwarfing of diseased plants. Grade 3: 1 / 3 of the leaves are mosaic but not deformed, or the diseased plants a...

Abstract

The invention relates to a method of controlling a tobacco mosaic disease using intercropping of rose pelargonium and cured tobaccos. The method comprises the steps of raising seedlings of the cured tobaccos and the rose pelargonium, intercropping the rose pelargonium and the cured tobaccos, transplanting the rose pelargonium and the cured tobacco at 20-25 DEG C, permit the rose pelargonium and the cured tobaccos to germinate after 2-5 days, applying 800-1000kg of organic fertilizer per mu as a base fertilizer, and applying a thin liquid fertilizer every other 7-10 days in a flowering phase. Ausage amount of pesticides is reduced, and safety, yield and quality of the cured tobaccos are improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco pest control, and relates to a method for controlling tobacco mosaic disease by intercropping geranium geranium and flue-cured tobacco. Background technique [0002] The intercropping of crops has a long history and is the essence of traditional Chinese fine agriculture. Studies have shown that intercropping certain crops in a reasonable manner can effectively improve the plant population structure and enable plants to make full use of light, water, heat, air, fertilizer and other conditions, thereby increasing the biological yield or economic yield of crops, The purpose of improving crop quality. At the same time, the reasonable application of these measures can also maximize the resistance of crop populations to adversity, control or reduce the occurrence of certain diseases and insect pests, and achieve the effect of reducing the use of pesticides and protecting the ecological envir...
