Embodiment 1

[0032] The control test was carried out at the Yuxi Base of Yunnan Academy of Tobacco Agricultural Sciences and Dali Hongda Experimental Base for 2 consecutive years from 2016 to 2017. The tobacco species tested was Honghua Dajinyuan. There are 3 control methods, one of which is the method of the present invention Control, one is the classic control under the open-air traditional cultivation mode, the other is the classic control of the smoke on the film, and the control is no control under the open-air traditional cultivation mode. Sowing time is March 5-10 (March 6, 2016, March 8, 2017), transplanting time: April 10-20 for seedlings under mulch (April 16, 2016, April 2017) May 13th), open-air and film smoking from May 1st to 20th (May 8th, 2016, May 12th, 2017). 600 tobacco plants in each model and 300 control plants were carried out according to the comparative experiment in the same field, and repeated in 3 plots. The main measures of disease prevention in each mode of cu...

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 in particular relates to a method for preventing and treating field tobacco black shank by combining early prevention and health-care cultivation. Background technique [0002] Tobacco black shank is a soil-borne disease that has occurred for many years. It occurs commonly in countries all over the world and is a devastating disease in tobacco production. At present, a large number of researches have been carried out in terms of cultivation techniques and measures, which have achieved good results in controlling the occurrence of black shank. Properly early transplanting period can reduce the incidence rate and degree of tobacco black shank disease (Zeng Chen, Chen Qingyuan, Peng Jie et al. Effects of different transplanting periods on the occurrence of tobacco black shank and mosaic disease. Hubei Agricultural Science, 2012, 51(12):2479-2481), health-care cult...
