Problems solved by technology

At present, the cultivation of tobacco crops in my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain high yields of tobacco leaves, which has caused serious damage to the soil and environment of tobacco leaf cultivation, and caused abnormal soil nutrients in some high-quality tobacco areas that have been planted for a long time. Balanced enrichment and depletion, unbalanced soil nutrient supply, and deterioration of farmland ecological environment lead to a significant decline in the quality of tobacco leaves and the benefits of tobacco planting, causing losses to tobacco growers and restricting the sustainable development of tobacco production

Embodiment 1

[0013] The tobacco-specific fertilizer provided in this embodiment is made from the following raw materials in parts by weight: 20 parts of urea, 5 parts of ammonium nitrate, 10 parts of superphosphate, 10 parts of potassium sulfate, 2 parts of ammonium bicarbonate, and 8 parts of diammonium phosphate , 25 parts of biogas residue, 20 parts of rapeseed cake fertilizer, 10 parts of plant ash, 10 parts of purple sweet potato, 1 part of amino acid, and 1 part of medium and trace elements. The medium and trace elements are a mixture of calcium, manganese, boron, and zinc, and the weight ratio of calcium, manganese, boron, and zinc is: calcium:manganese:boron:zinc=2:1:2:2.

[0014] The preparation method of the tobacco-specific fertilizer provided in this example: mix the various raw materials, stir them evenly, and granulate them by conventional techniques.

Embodiment 2

[0016] The tobacco-specific fertilizer provided in this embodiment is made from the following raw materials in parts by weight: 16 parts of urea, 12 parts of ammonium nitrate, 10 parts of superphosphate, 25 parts of potassium sulfate, 8 parts of ammonium bicarbonate, and 11 parts of diammonium phosphate , 20 parts of biogas residue, 16 parts of rapeseed cake fertilizer, 7 parts of plant ash, 9 parts of purple sweet potato, 1 part of amino acid, and 3 parts of medium and trace elements. The medium and trace elements are a mixture of calcium, manganese, boron, and zinc, and the weight ratio of calcium, manganese, boron, and zinc is: calcium:manganese:boron:zinc=2:1:2:2.

[0017] The preparation method of the tobacco-specific fertilizer provided in this example: mix the various raw materials, stir them evenly, and granulate them by conventional techniques.

Embodiment 3

[0019] The tobacco-specific fertilizer provided in this embodiment is made from the following raw materials in parts by weight: 5 parts of urea, 15 parts of ammonium nitrate, 3 parts of superphosphate, 15 parts of potassium sulfate, 10 parts of ammonium bicarbonate, and 16 parts of diammonium phosphate , 10 parts of biogas residue, 10 parts of rapeseed cake fertilizer, 2 parts of plant ash, 5 parts of purple sweet potato, 3 parts of amino acid, and 2 parts of medium and trace elements. The medium and trace elements are a mixture of calcium, manganese, boron, and zinc, and the weight ratio of calcium, manganese, boron, and zinc is: calcium:manganese:boron:zinc=2:1:2:2.

Abstract

The invention relates to the technical field of fertilizers and particularly discloses a special fertilizer for tobaccos. The special fertilizer for the tobaccos comprises, by weight, 5-20 parts of urea, 5-15 parts of ammonium nitrate, 3-10 parts of calcium superphosphate, 10-25 parts of potassium sulphate, 2-10 parts of ammonium bicarbonate, 8-16 parts of diammonium phosphate, 10-25 parts of biogas residues, 10-20 parts of rape seed cake fertilizers, 2-10 parts of plant ashes, 5-10 parts of vetch seeds, 1-3 parts of amino acids and 1-3 parts of medium trace elements. The special fertilizer for the tobaccos has the advantages that the component match is reasonable, the balance reasonable absorption of nutritional ingredients by the tobaccos can be facilitated by the synergistic effect of the nutritional ingredients, the special fertilizer is adapted to the fertilizer requirement rule of tobacco growth, and thereby the yield and quality of the tobaccos can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer 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 cultivation of tobacco crops in my country mainly relies solely on the large-scale application of chemical fertilizers and pesticides to maintain high yields of tobacco leaves, which has caused serious damage to the soil and environment of tobacco leaf cultivation, and caused abnormal soil nutrients in some high-quality tobacco areas that have been planted for a long time. Balanced enrichment and depletion, unbalanced soil nutrient supply, and deterioration of farmland ecological environment lead to a significant decline in tobacco leaf quality and tobacco planting benefits, causing losses to tobacco growers and restricting the sustainable development of tobacco product...
