Fertilizing method in flue-cured tobacco production

Abstract

The invention relates to a fertilizing method in flue-cured tobacco production, and belongs to the technical field of flue-cured tobacco fertilization. In the method, before a flue-cured tobacco sprout is cultured, the total quantity of a fertilizer is determined by measuring earthwork according to the required height of a field ditch, and 95 percent of the fertilizer serving as a base fertilizer based on the total quantity of the fertilizer is fertilized into the field ditch twice; and after the flue-cured tobacco sprout is cultured, the fertilizer in an amount which accounts for 5 percent of the total quantity of the fertilizer is fertilized in the field ditch, which is 10 to 15cm deviated from the center of the sprout. The method comprises the specific steps of: a, performing single fertilization on the upper side of the field ditch by using 57 percent of the fertilizer serving as a first base fertilizer based on the total quantity of the fertilizer which is determined by measuring the earthwork according to the required height of the field ditch; b, after fertilizing the field ditch by using the first base fertilizer, clearing the field ditch to 25cm on the upper side of the field ditch, and performing single fertilization on the upper side of the field ditch by using 38 percent of the fertilizer serving as a second base fertilizer based on the total quantity of the fertilizer; and c, covering 5 to 8cm soil on the surface which is fertilized by the second base fertilizer, controlling the height of the field ditch to be 40cm, and allowing two layers of fertilizers to be arranged vertically in the center of a ridge. The method has the advantages of uniform fertilization, long time for fertility, fast maturity of a tobacco plant, and capability of effectively preventing the fertilizer deficiency and reducing the labor intensity.

Description

Technical field: [0001] The invention relates to a fertilization method in planting flue-cured tobacco, belonging to the technical field of flue-cured tobacco fertilization. Background technique: [0002] Tobacco is an important economic crop in our country. In many areas, tobacco planting is the most important source of income for local people. The quality of tobacco leaves is affected by factors such as climate and cultivation measures. With the standardized production of tobacco leaves and the construction of modern tobacco agriculture, tobacco leaf production technology needs a series of improvements. Precise and efficient fertilization has become a key technology to improve yield and quality. At present, the four-purpose methods of flue-cured tobacco base fertilizer mainly include single row application, hole application and positioning ring application. Single row application is easy to operate, but the fertilizer position is far away from the root system of the toba...
