Flue-cured tobacco cultivation method capable of effectively controlling high-nitrogen soil fertility

Abstract

The invention discloses a flue-cured tobacco cultivation method capable of effectively controlling high-nitrogen soil fertility. The cultivation method comprises the following steps: A. before transplantation, making a pond in a tobacco field, and applying a phosphate fertilizer in the pond; B. during the transplantation, applying an organic magnesium potassium sulfate fertilizer, an organic induced disease-resistant agent, a microbial inoculant and biochar into the pond, and after finishing the transplantation, applying well-rotted farmyard manure and covering the pond; C. 10-15 days after the transplantation, applying an all-water-soluble organic fertilizer solution in the pond; D. 40-60 days after the transplantation, spraying an organic potassium fertilizer and a boron zinc molybdenum fertilizer; and E. 55-60 days after the transplantation, carrying out tip pruning on the tobacco plants. The method is simple to operate, and is capable of effectively controlling the high-nitrogen soil fertility and lowering the residual nitrogen element in the high-nitrogen soil. The first batch of nitrogen element which can be easily decomposed in the soil is firstly released, thereby satisfying the demands of early growth and quick tillering of the transplanted tobacco plants. Meanwhile, the method can effectively control the phenomena of regreening and excessive vegetative growth in the tobacco plants.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a flue-cured tobacco cultivation method capable of effectively controlling the fertility of high-nitrogen soil. Background technique [0002] At present, the plots for planting flue-cured tobacco are becoming more and more complicated due to the diversification of the previous crops, especially the impact of some economic crops such as watermelon, Panax notoginseng, vegetables, etc., making the plots that were easy to grow high-quality flue-cured tobacco become "the best" for planting flue-cured tobacco. Taboo", when planting flue-cured tobacco on this kind of soil, the tobacco plants will either grow wildly or grow abnormally. The reason is mainly that once watermelon, Panax notoginseng, vegetables and other plants are planted in the previous work, the soil often has high nitrogen content, but other elements such as phosphorus, potassium, magne...

AI Technical Summary

Problems solved by technology

Usually, the solution to the high-nitrogen soil of previous vegetables, watermelon or notoginseng is to carry out soil improvement, such as deep plowing method, guest soil method, application of organic fertilizer, etc. However, the first two methods of soil improvement are time-consuming and laborious, especially the guest The soil method requires a lot of manpower and material resources; and the application of organic fertilizers is relatively slow, especially after the tobacco plants are transplanted, it is necessary to promote the early growth and rapid growth of the tobacco plants, and the slow effect of organic fertilizers will affect the cultivation process, resulting in poor quality of flue-cured tobacco. influences
