A 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 the fertility of high-nitrogen soil. The cultivation method specifically includes the following steps: A. before transplanting, making a pond in the tobacco field, and then applying phosphorus fertilizer in the pond; B. transplanting When planting, apply organic potassium magnesium sulfate fertilizer, organic induced disease resistance agent, microbial bacterial agent, biochar in the pond, after transplanting is completed, apply decomposed farmyard manure to cover the pond; C, 10 to 15 days after transplanting, in Pouring water-soluble organic fertilizer solution in the pond; D. 40-60 days after transplanting, spraying organic potassium fertilizer, boron, zinc and molybdenum fertilizer; E. 55-60 days after transplanting, topping the tobacco plants. The invention is easy to operate, can effectively control the fertility of high-nitrogen soil, and reduce the residual nitrogen element in high-nitrogen soil; the invention can release the first batch of nitrogen elements that are easy to decompose in the soil first, and meet the requirements of early growth and rapid growth of tobacco plants after transplanting. At the same time, it can effectively control the phenomenon of turning green and excessive growth of 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
