Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer application equipment, in particular to a tobacco field fertilizer application equipment. Background Art

[0002] When planting tobacco in mountainous areas, the high degree of mechanization is not suitable for the mountains, so backpack-type quantitative fertilization is mostly used. In view of the large differences in soil types and fertility in this planting area and the long-term use of fixed fertilization methods in the production of flue-cured tobacco, research on planting block fertilization technology is carried out.

[0003] According to the results of soil nutrient analysis, fertilization tests of different types of medium and micro-fertilizers are carried out to identify the types of medium and micro-fertilizers that can further improve the quality of tobacco leaves, and eventually a technical plan for block fertilization of flue-cured tobacco is formed. The amount of fertilizer applied of various types of fertilizers will be slightly different. At the same time, eccentric fertilizers, supplementary fertilization and other measures will be carried out. There will be certain differences in the amount of eccentric fertilizers, supplementary fertilization, etc. The existing fertilization equipment uses a fixed number of fertilizers, which can only release a fixed amount of fertilizer at a time. This results in excessive fertilization, causing a certain amount of waste. Summary of the invention
