Embodiment 1

[0032] The control test was carried out at the Yuxi Base of Yunnan Academy of Tobacco Agricultural Sciences and the Dali Hongda Test Base for two consecutive years from 2016 to 2017. The tested tobacco variety was Honghua Dajinyuan. There were three control methods, one of which was the method of the present invention. Control, one is the classic control under the traditional open-air cultivation mode, the other is the classic control against the smoke on the film, and the contrast is the no control under the traditional open-air cultivation mode. Sowing time is March 5-10 (March 6, 2016, March 8, 2017), and transplanting time: Seedlings under the mulch are April 10-20 (2016, April 16, 2017 On 13th), open air and film smoking are May 1-20 (May 8, 2016, May 12, 2017). 600 tobacco plants of each model and 300 control plants were carried out according to the same field comparison test, repeated on 3 plots. The main measures for disease prevention in each mode of cultivation are a...

Abstract

The invention discloses a method for combining early prevention with healthy cultivation to prevent and control a field tobacco black shank disease. The method refers to farming operation of carrying out transplanting seedlings under tobacco film and is characterized by achieving a whole-process continuous technique for preventing and controlling the black shank disease of filed tobacco plants, wherein in the technique, agricultural prevention and control serve a main measure, chemical prevention and control serve as a supplementary measure, and microhabitat adjustment of the seedlings under the tobacco film, early transplanting and disease avoidance, early prevention and drug application, water and fertilizer coupling nutrition regulation and resistance improvement of the adult plants are adopted. The method has the advantages of being convenient to operate and high in efficiency, saving water and labor, preventing and controlling the tobacco black shank disease in a pollution-free and whole-process mode and the like, and is the green tobacco black shank disease prevention and control technique worth popularizing.

Description

Technical field [0001] The invention belongs to the technical field of tobacco disease prevention and control, and specifically relates to a method for preventing and treating field tobacco black shank by combining early prevention and health cultivation. Background technique [0002] Tobacco black shank is a soil-borne disease that has occurred year after year, and it is widespread in countries all over the world. It is a devastating disease in tobacco production. At present, a large number of researches have been carried out on cultivation techniques and measures, which have played a good effect in controlling the occurrence of black shank. Properly early transplanting period can reduce the incidence and degree of tobacco black shank disease (Zeng Chen, Chen Qingyuan, Peng Jie, etc. The influence of different transplanting periods on the occurrence of tobacco black shank and mosaic disease. Hubei Agricultural Science, 2012, 51(12): 2479-2481), health-care cultivation technique...
