Abstract

The invention relates to the technical field of agriculture, and discloses a biological fertilizer for controlling tobacco black shank and a preparation method thereof. The biological fertilizer comprises following components in parts by weight: 26 to 30 parts of rape seed cakes, 18 to 22 parts of a nitrogen fertilizer, 13 to 20 parts of a phosphate fertilizer, 16 to 22 parts of a potassium fertilizer, 2 to 3 parts of humic acid, 2 to 3 parts of amino acids, 3 to 9 parts of oyster shell powder, 0.5 to 2.5 parts of medium trace elements, 0.5 to 2 parts of chitosan, and 1 to 3 parts of a composite biological inoculant. Fermented rape seed cakes are mixed with a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer, humic acid, amino acids, oyster shell powder, medium trace elements, chitosan, and a composite biological inoculant, and then the mixture is grinded and blended to prepare the biological fertilizer. The biological fertilizer has comprehensive nutrients, can supply enough nutrients for the growth of tobaccos and well control tobacco black shank, and is capable of reducing the using amount of chemical pesticides and chemical fertilizers and improving the soil and tobacco quality.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a biological fertilizer for preventing and treating tobacco black shank and a preparation method thereof. Background technique [0002] Tobacco black shank is one of the most destructive diseases in tobacco production. It commonly occurs in various smoking areas in my country. In recent years, with the increase of continuous cropping years and the large input of chemical fertilizers, the damage of tobacco black shank has increased significantly. The trend has a certain impact on tobacco leaf production. Tobacco black shank has a wide host range and can infect eggplant, tomato, strawberry, Dendrobium officinale and other plants. At present, the prevention and treatment of tobacco black shank disease is generally drug prevention and treatment. After the onset, propamocarb hydrochloride and azoxystrobin are used for spraying treatment. The control effect is not good,...
