Fungicide special for apple tree replant disease and preparation method thereof

Abstract

The invention discloses a fungicide special for apple tree replant disease. The fungicide includes the following raw materials by volume: 20-40 parts of pseudomonas, 5-15 parts of streptomyces, 5-20 parts of yeast, 2-10 parts of actinomycetes, 2-10 parts of bacillus amyloliquefaciens, 10-20 parts of bacillus subtilis, 1-10 parts of potassium-releasing trichoderma, 5-12 parts of phosphorus-dissolving Aspergillus niger, 5-15 parts of Beijerinckia, and 100-200 parts of auxiliary materials. Specifically, the pseudomonas, streptomyces, yeast, actinomycetes, bacillus amyloliquefaciens, bacillus subtilis, potassium-releasing trichoderma, phosphorus-dissolving Aspergillus niger, and Beijerinckia are respectively prepared by individual culture for 48h according to an inoculation amount of 0.2-0.4%.The auxiliary materials include, by weight, 20-40 parts of lactose, 1-3 parts of polyethylbenzene pyrrolidone K30, 1-2 parts of tartaric acid and 5-15 parts of sodium bicarbonate. The invention alsodiscloses a preparation method of the fungicide special for apple tree replant disease.

Description

technical field [0001] The invention relates to the technical field of special bacterial agents, in particular to a special bacterial agent for apple tree replantation disease and a preparation method thereof. Background technique [0002] Apple trees are perennial plants, and when old orchards are regenerated, serious replanting diseases will occur, also called replanting obstacles or heavy cropping diseases. After the old trees in the old orchard are excavated, it needs to be fallow or rotated for 3-5 years before planting new seedlings, such as millet, corn, rape, soybeans, vegetables, etc. , the economic benefit is extremely poor. As the apples in the main producing areas such as Shandong and Liaoning gradually enter the aging period, in the future, at least 10% of the apple tree orchards in my country will need to be rebuilt due to old trees, serious diseases, and poor returns. After these apple trees are excavated, Due to the impact of replantation disease, the garden...

After the old trees in the old orchard are excavated, it needs to be fallow or rotated for 3-5 years before planting new seedlings, such as millet, corn, rape, soybeans, vegetables, etc. , the economic benefit is extremely poor

As the apples in the main producing areas such as Shandong and Liaoning gradually enter the aging period, in the future, at least 10% of the apple tree orchards in my country will need to be rebuilt due to old trees, serious diseases, and poor returns. After these apple trees are excavated, Due to the impact of replanting disease, the orchard cannot be established in time, and it takes 3-5 years to establish the orchard, which will cause great economic losses to the fruit growers
