Problems solved by technology
Due to the instant dissolving properties of many types of fertilizers currently applied, only 30% to 50% of them can be absorbed and utilized by tobacco after being applied to the soil, and most of the others are lost, resulting in fertilizer loss. It has caused serious damage to the environment and caused unbalanced enrichment and depletion of soil nutrients in some high-quality tobacco areas that have grown tobacco for a long time. The supply of soil nutrients is unbalanced, and the ecological environment of farmland has deteriorated, resulting in obvious tobacco leaf quality and tobacco planting benefits. Decline, causing losses to tobacco growers, but also restricting the sustainable development of tobacco production

Embodiment 1
[0053] 30 kg of compound fertilizer (N, P in the compound fertilizer 2 o 3 、K 2 The mass ratio of O is 1: 3:2.4), 20 kg of organic matter, 10 kg of amino acids, 10 kg of sesame cake fertilizer, 2 kg of ethylenediaminetetraacetic acid, 2 kg of citric acid, and 2 kg of polyaspartic acid Acid, 5 kg of boron sulfate, 5 kg of magnesium sulfate heptahydrate, 2 kg of molybdenum sulfate, 5 kg of ferrous sulfate, 5 kg of zinc sulfate heptahydrate and 2 kg of general calcium are mixed and granulated to make tobacco special fertilizer .
[0054] The above special fertilizer for tobacco was tested in the tobacco field, and only one fertilization was required without topdressing. Compared with conventional fertilizers, the biomass of roots, stems, and leaves of tobacco plants increased significantly.

Abstract
The application provides tobacco special purpose fertilizer. The tobacco special purpose fertilizer comprises, by mass, 15 to 45 parts of compound fertilizer, 10 to 30 parts of organic matters, 1 to 15 parts of amino acids, 1 to 15 parts of sesame cake fertilizer, 0.5 to 3 parts of ethylenediaminetetraacetic acid, 1.5 to 2 parts of citric acid, 2 to 5 parts of polyaspartic acid, 5 to 7 parts of boron sulfate, 2 to 8 parts of magnesium sulfate heptahydrate, 1 to 5 parts of molybdenum sulfate, 3 to 10 parts of ferrous sulfate, 2 to 6 parts of zinc sulfate heptahydrate and 1 to 3 parts of calcium superphosphate. The tobacco special purpose fertilizer contains all the nutrients needed by tobacco. Through a scientific ratio, the tobacco special purpose fertilizer can greatly improve the utilization rate of fertilizer, effectively improve the soil aggregate structure, and play the role of soil improvement, water conservation and soil amelioration.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to special fertilizers for tobacco. Background technique [0002] Tobacco is one of the important economic crops in my country, and its planting area and total output both rank first in the world. At present, the planting of tobacco crops in my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain a high yield of tobacco leaves. Due to the instant dissolving properties of many types of fertilizers currently applied, only 30% to 50% of them can be absorbed and utilized by tobacco after being applied to the soil, and most of the others are lost, resulting in fertilizer loss. It has caused serious damage to the environment and caused unbalanced enrichment and depletion of soil nutrients in some high-quality tobacco areas that have grown tobacco for a long time. The supply of soil nutrients is unbalanced, and the ecological e...
