The invention relates to compound biogas slurry insecticidal liquid and a preparation method. The insecticidal liquid is the compound biogas slurry insecticidal liquid which is prepared by a pesticide and biogas slurry in weight by percent: 0.02-0.2 percent of beta-cypermethrin and the biogas slurry, and 0.003-0.05 percent of imidacloprid and the biogas slurry. The preparation method comprises the following steps of: taking out the biogas slurry from a middle-layer discharging port of a biogas fermentation tank of which the biogas is normally fermented for over three months, wherein the total solid content of the biogas slurry is 10-12 percent; standing for 30 minutes; filtering to remove particle impurities to prepare the biogas slurry; reasonably mixing the biogas slurry and the beta-cypermethrin or the imidacloprid according to the weight percentage; fully stirring the mixture; and uniformly mixing. According to the compound biogas slurry insecticidal liquid and the preparation method, the biogas slurry generated in the anaerobic fermentation process of poultry excrement wastes is adopted, and the commonly-used insecticide is reasonably matched, so that common insect pests of a plurality of vegetable crops of kidney beans, eggplants, cabbages and the like can be effectively prevented; the insecticidal liquid is simple in preparation method, easy to operate and convenient to use, can reduce the using amount of the pesticides, and is suitable for being popularized; and the insecticidal liquid has the characteristics of efficiency, environment friendliness and low cost.

The present invention belongs to a plant magnetism polyurethane foam plastic immobilized microorganism cell and the technology field of the biological degradation chemical pesticide, and relates to the magnetic immobilization to a strain cell which highly and effectively degrades the pyrethroid pesticide. The bacterial strain is acinetobacter (Acinetobacter sp.) JCX22D strain, which uses botanical wastes as polymerization material, and Fe 3 O 4 as a magnetic component, a cold curing technology is adopted to perform the immobilization of the strain cell, and the immobilized cell can be recycled through adding the magnetic field. The degradation efficiency of the immobilized cell to highly effective cypermethrin, lamba cyhalothrin and bifenthrin is more than 70 percent, the degradation efficiency to naled, methyl parathion, phoxim and chlorpyrifos is over 60 percent, and the degradation efficiency to avermectins is 85 percent. The magnetic immobilized cell can be used for the biolobical repair or biological purification of a water body polluted by the pesticide.

The invention provides a beta-cypermethrin degrading bacteria-nitrogen-fixing vibrio (Azoarcus Indigens) HZ5, which is collected at the China center for type culture collection, wherein the address is Wuhan University of Luojia hill, Wuhan, Hubei, 430072, the collection data is March 17, 2010, and the collection number CCTCC No is M 2010060. The bacteria of the invention has certain degradation capacity to high-concentration beta-cypermethrin, the degradation rate for the 50mg / L of beta-cypermethrin under pure culture conditions reaches 65.2%, and the enantioselectivit does not exist in the degradation process.
