Problems solved by technology

When the nitrogen utilization rate is low, the amino acid content and petroleum ether extract content in the tobacco leaves will decrease, resulting in a decrease in the quality of the tobacco leaves; in terms of smoking quality, the aroma of the tobacco leaves is obviously insufficient, the miscellaneous gas is lighter, and the taste is slightly astringent, light smoke
At the same time, when the nitrogen utilization rate is low, it will also lead to a serious decline in tobacco production and affect the economic benefits of tobacco.

Abstract

The invention discloses a fertilization method for improving nitrogen element utilization rate of flue-cured tobacco. The fertilization method comprises the following steps: (1) leveling the land and applying basic fertilizer; (2) transplanting with water and fertilizer; (3) applying a hole-applied fertilizer; (4) applying foliage fertilizer; (5) applying after-manuring; and (6) applying balanced fertilizer. The fertilization method can effectively improve nitrogen element utilization rate of flue-cured tobacco, reduce production cost, and improve quality, yield and economic benefits of the tobacco leaves; charcoal made of rice straw is applied, straws return to the field, and the problem that the conventional firing method for treating rice straws pollutes the environment can be solved. The fertilization method can improve physicochemical property and fertility of the soil for planting tobacco.

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco planting, and in particular relates to a fertilization method for improving the nitrogen utilization rate of flue-cured tobacco. Background technique [0002] In my country's agricultural production, the utilization rate of chemical fertilizers is affected by factors such as single fertilization, fertilization amount, and improper fertilization methods, which lead to changes in soil conditions, deterioration of environmental conditions, decline in soil fertility, and generally low fertilizer utilization rates. According to statistics, the utilization rate of general chemical fertilizers is only 20-40%, while that in developed countries can reach 50-80%. [0003] my country is the largest country in the production and consumption of chemical fertilizers in the world, and the production of chemical fertilizers consumes a lot of energy. According to statistics, my country consumes 60 million tons m...
