Abstract

The invention discloses a biological fertilizer for preventing and controlling root black rot of tobacco, and a preparation method thereof, and belongs to the technical field of tobacco disease and pest control. The biological fertilizer comprises 26-30 parts of Acer truncatum seed cake meal, 18-22 parts of a nitrogen fertilizer, 13-20 parts of a phosphorus fertilizer, 16-22 parts of a potassium fertilizer, 2-3 parts of mineral source potassium fulvate, 1-2 parts of polyaspartic acid, 4-9 parts of conch shell powder, 0.5-2.5 parts of medium trace elements, 0.5-2 parts of chitosan, 0.5-1 part of agricultural algin, 0.5-1 part of glucose and 1-3 parts of a composite microbial agent. The biological fertilizer is prepared from the raw materials through the processes of crushing, mixing and thelike. The product is comprehensive in nutrients, can meet the requirements of tobacco growth for nutrient elements, has a good control effect on the root black rot of tobacco, can reduce the application of chemical pesticides and chemical fertilizers after being applied, and has the effects of soil conservation and tobacco quality improvement.

Description

technical field [0001] The invention belongs to the technical field of tobacco pest control, and in particular relates to a biological fertilizer for preventing and controlling tobacco root black rot and a preparation method thereof. Background technique [0002] Tobacco root black rot is a fungal disease that harms tobacco. It occurs all over the world. It can be infected at the seedling stage and larger tobacco plants. After infection, it can make tobacco young stems, cotyledons and root tips black and rot , the roots of severely diseased plants are all rotten and black, the tobacco plants grow slowly, turn yellow and dwarf, and the leaves turn yellow and thin, which seriously affects the yield and quality of tobacco. [0003] Tobacco root black rot is caused by fungi belonging to the subphylum Deuteromycota. The pathogen can infect more than 120 kinds of plants in 30 families such as Solanaceae, Fabaceae, Cucurbitaceae, etc. The pathogen mainly parasitizes on diseased re...
