[0032] Embodiment 1 The method for reducing phoxim residues in green onions by using Glomus mosesi or glomus in root fungi

[0033] (1) Expansion of Glomus mosei or Glomus intrarhizoi

[0034] Glomus mosseae BEG 167 or Glomus intraradices BEG 141 are provided by China Agricultural University, Glomus mosseae and Glomus intraradices have been registered and preserved in the European Culture Collection Center, and the BEG 167 and BEG 141 are the accession numbers.

[0035] Sieve the river sand and peat through a 1mm fine sieve and sterilize at 121°C for 2 hours, then mix and stir the river sand and peat at a volume ratio of 1:1 to form a matrix . Inoculate Glomus moses or Glomus intraradices respectively with the inoculum amount of 5% by mass in the matrix, then add 20% water in the matrix, sow the seeds of Sudan grass, and Sudan grass grows Pour 1 / 4 strength Hoagland (Hoagland) nutrient solution once every 3 weeks according to 10% of the mass of the substrate. This nutrient s...

Abstract

The invention relates to a method for reducing vegetable phoxim residue by utilizing glomus mosseae or glomus intraradices. Arbuscular mycorrhiza homobium is formed by mainly utilizing glomus mosseae or glomus intraradices and a vegetable crop to reduce phoxim residue in a vegetable. The method of the invention comprises the following steps of: propagating the glomus mosseae or the glomus intraradices; using a glomus mosseae microbial inoculum or a glomus intraradices microbial inoculum on vegetables; and applying phoxim and managing the vegetable until the growth period of the vegetable crop is finished. The method of the invention is suitable for vegetable crops easy to form arbuscular mycorrhiza of a potato family, a lily family, a gourd family, a bean family, and the like. The method of the invention can reduce phoxim residue in soil and vegetables, prevent pesticide from being transferred to environments of water bodies, atmosphere, and the like and lessen harm to the health of human bodies and is simple, convenient and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and in particular relates to a method for reducing vegetable phoxim residues by using Glomus moesei or Glomus intraradices. Background technique [0002] Phoxim is one of the most widely used organophosphorus pesticides in my country and has acute toxicity. Commonly used phoxim is powder or emulsifiable concentrate, which has a wide insecticidal spectrum and is often used to control various pests. It has a long residual period after being applied to the soil, and is especially suitable for controlling underground pests. The methods of applying phoxim pesticide usually include spraying, root irrigation, seed dressing or soil mixing, etc., and the application time can be before planting vegetables and during the various growth stages of vegetables. The residue of phoxim in the soil often leads to excessive residues in vegetables, and it will be transferred to the enviro...
