Abstract

The invention relates to a disease resisting leaf fertilizer for tobaccos. The fertilizer comprises the following raw materials in parts by weight: 2-4 parts of ferrous sulfate, 20-25 parts of zinc sulfate, 5-8 parts of manganese sulfate, 8-10 parts of magnesium sulfate, 10-20 parts of monopotassium phosphate, 15-25 parts of sodium nitrate or / and calcium nitrate, 5-8 parts of glutamic acid, 3-5 parts of cysteine, 3-5 parts of organic selenium, 5-12 parts of lightyellow sophora root extract powder, 8-15 parts of capillin extract powder,, 3-10 parts of Lvdi emulsifiable concentrate, 5-7 parts of carboxymethylcellulose and 2-5 parts of chitosan. When the fertilizer is in use, 50-200 kg of water is added, the system pH (potential of Hydrogen) value is 6-7 and the pH can be adjusted by adopting citric acid. The disease resisting leaf fertilizer for the tobaccos, disclosed by the invention, has the advantages that a specific amount of the organic selenium is added to ensure that trace elements of the tobaccos can be supplemented, the activity of various enzymes in leaves can be stimulated and the metabolic process of upper leaf growth is promoted, so that the leaf growth is more vigorous.

Description

technical field [0001] The invention relates to a tobacco disease-resistant foliage fertilizer, in particular to a fertilizer that coordinates tobacco growth, balances nutrition, effectively prevents or prevents tobacco diseases, and improves the disease resistance and quality of tobacco. Background technique [0002] Tobacco leaves need to be moderate in thickness, good in color, rich in flavor, and balanced in content of nicotine and protein. Tobacco diseases, nicotine and potassium content seriously affect the quality of tobacco leaves. The uneven nutrient composition in the existing foliage fertilizer leads to imbalance of nicotine content in tobacco. [0003] Tobacco virus disease, commonly known as tobacco mosaic disease, is the most widely distributed and most common disease in tobacco production. At present, 16 kinds of tobacco virus diseases have been discovered in my country, among which the viruses that cause tobacco mosaic disease mainly include TMV, CMV, and PV...
