Microbial agent for controlling quarantine fungus diseases of apples and promoting yield increase

Abstract

The invention discloses a microbial agent for preventing and controlling quarantine fungus diseases of apples and promoting yield increase. The microbial agent is prepared from raw materials in parts by weight as follows: 10-15 parts of streptomyces microflavus, 10-15 parts of bacillus subtilis, 15-25 parts of chaetomium globosum, 8-10 parts of bacillus laterosporus, 15-20 parts of bacillus amyloliquefaciens, 8-10 parts of bacillus circulans, 10-20 parts of trichoderma harzianum, 5-10 parts of trichoderma asperellum, 5-10 parts of trichoderma fasciculatum bissett, 5-10 parts of paecilomyces lilacinus, 8-12 parts of streptomyces syringini, 8-12 parts of gordonia, 8-12 parts of conexibacter, 5-10 parts of alga oligosaccharide and 10-15 parts of chitosan oligosaccharide citrate. The microbial agent can effectively inhibit the quarantine fungus diseases and can strengthen apple trees, and the yield increase purpose can be achieved; chaetomium globosum has remarkable bactericidal and bacteriostatic activity for valsa ceratosperma of the apple trees; no pesticides are used, the microbial agent is non-toxic, harmless, pollution-free and residue-free, the quality and the safety of agricultural products are guaranteed, and the apples have pure taste and high sweetness.

Description

technical field [0001] The invention relates to the field of plant disease prevention and control, in particular to a bacterial agent for preventing and controlling apple quarantine fungal diseases and promoting yield increase. Background technique [0002] Apple belongs to Rosaceae, a deciduous tree with oval leaves and serrated leaves; the fruit is spherical and sweet, and it is an ordinary fruit and the most common fruit. It is rich in nutrition and is one of the four major fruits in the world (apple, grape, citrus and bananas). Apples are usually red, but yellow and green are also available. Apple is a dicotyledonous plant with light red or lavender flowers. Most of them are self-sterile and require cross-pollination. The fruit develops from the ovary and receptacle. The pulp is crisp and sweet, which can help digestion. Rosaceae, Malus genus, tree, up to 15 meters, trunk taupe, old bark with irregular longitudinal fissures or flakes, branchlets densely hairy when you...

Problems solved by technology

[0003] In recent years, the control of apple quarantine fungal diseases still uses chemical agents as the main control method, but due to the latent infection characteristics of apple quarantine fungal diseases in the tree, chemical pesticides cannot solve the problem of recurrence of old scars, making the disease Year after year, it has not been effectively controlled so far; at the same time, due to the short efficacy period of chemical pesticides, the frequency of use and dosage are increasing, which has constituted a huge threat to fruit safety and environmental safety, directly affecting my country's International apple trade
