No-tillage aphid-preventing and disease-preventing efficient cultivation method for flue-cured tobacco

Abstract

The invention relates to a no-tillage aphid-preventing and disease-preventing efficient cultivation method for flue-cured tobacco, and belongs to the field of agriculture cultivation. According to the method, the labor amount can be reduced for tobacco growers, the labor cost can be lowered, the number of aphids flying to tobacco plants during the migratory flight peak season of the aphids can be reduced, the harm of spreading viral diseases by the aphids can be relieved, the yield of the tobacco can be increased, and the quality of the tobacco can be improved. According to the technological means, wheat is planted in a field in October of the first year according to a conventional method; tobacco seedlings are planted between the wheat lines in April of the next year, the row spacing is 50 cm, the line spacing is 1 m, and the depth of a hole for planting the tobacco seedlings is 5-8 cm; the wheat is harvested in June, the wheat stubble is 0.2-0.3 m high and is removed in 25-30 days after the wheat is harvested, fertilization and hilling are carried out on the tobacco plants, and then the field management stage of the flue-cured tobacco begins; after the flue-cured tobacco is harvested in September, the soil is ploughed for planting the wheat.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a no-tillage and high-efficiency cultivation method for preventing aphids and diseases of flue-cured tobacco. Background technique [0002] Most of the Huanghuai tobacco area adopts ridge farming. The main process of flue-cured tobacco ridge farming in the prior art is: raising seedlings, plowing the tobacco field, ridging, fertilizing, transplanting, field management, harvesting and other main steps. Since they are all manual labor, there are many steps in flue-cured tobacco cultivation , the amount of labor is large, which greatly increases the labor cost of flue-cured tobacco planting. [0003] Generally, flue-cured tobacco is monocultured in the Huanghuai Tobacco Area, and the multiple cropping index of crops is low; May and June each year is the peak period for the migration of flue-cured tobacco aphids, and the migration of aphids can cause damage expansion ...
