Planting method for breaking flue-cured tobacco successive cropping obstacle

Abstract

The invention relates to a planting method for breaking a flue-cured tobacco successive cropping obstacle, and belongs to the technical field of flue-cured tobacco cultivation. The method comprises the specific steps of conducting deep ploughing on the soil for planting the flue-cured tobacco, applying a farmyard manure, and then applying a base fertilizer; adopting an integration of water and fertilizer to irrigate tobacco seedlings; applying an enzyme charcoal into a tobacco pond during transplanting time of the flue-cured tobacco; dissolving bacillus amyloliquefaciens FZB42 microbial inoculum through root setting water, and watering the microbial inoculum to the tobacco pond; utilizing PGPR phosphate-dissolving and potassium-dissolving growth-promoting bacteria to prepare a bacterial suspension and fully soaking the root parts of flue-cured tobacco plants in the bacterial suspension before transplanting the flue-cured tobacco, and then transplanting the flue-cured tobacco; conducting field management; spraying flue-cured tobacco tablets on the blades at the upper parts during the topping period of the flue-cured tobacco; spraying an organic state blade surface potash fertilizer after topping. According to the planting method for breaking the flue-cured tobacco successive cropping obstacle, the problems that the structure and the physicochemical property of the soil deteriorate after successive cropping of the tobacco, the root system of the flue-cured tobacco is hypogenetic, the growth and development and nutrient absorption and utilization of the tobacco plants are limited, and the quality of the tobacco is reduced are solved, through the application of the method, obstacle crop failure generated by the successive cropping of the flue-cured tobacco is solved at the maximum, and the purpose that the yield and the quality of the flue-cured tobacco and the fertilizer efficiency are simultaneously improved is achieved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a planting method for breaking the obstacle of continuous cropping of flue-cured tobacco. Background technique [0002] Tobacco areas are short of land resources, and continuous cropping in flue-cured tobacco production is very common. Tobacco is a kind of economic crop that avoids continuous cropping. Long-term continuous cropping will cause nutrient imbalance in tobacco field soil, deterioration of physical and chemical properties, frequent occurrence of pests and diseases, and serious occurrence. Sexual decline, resulting in stunted tobacco root development, reduced growth of tobacco plants, and varying degrees of decline in yield and quality. At present, continuous cropping obstacles have become the key to restricting the further improvement of flue-cured tobacco yield and quality. However, it is difficult to effectively alleviate the limi...

Problems solved by technology

[0005] In order to overcome the problems existing in the background technology, the present invention provides a planting method to solve the obstacles of flue-cured tobacco continuous cropping, which solves the deterioration of soil structure and physical and chemical properties, poor growth of flue-cured tobacco roots, and limited growth and nutrient absorption and utilization of tobacco plants after tobacco continuous cropping , the problem of decline in tobacco leaf yield and quality, improve the physical and chemical properties of flue-cured tobacco rhizosphere soil, regulate the rapid growth and development of roots, improve the nutrient absorption of tobacco plants in the field, ensure the water demand for tobacco plant growth, promote the opening of upper tobacco leaves, improve the quality of middle and upper tobacco leaves, and , through the application of this technology, the obstacle production reduction caused by continuous cropping of flue-cured tobacco can be solved to the greatest extent, and the yield, quality and fertilizer efficiency of flue-cured tobacco can be improved at the same time
