     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention belongs to the fields of family safety, harmlessness, environmental protection, bacteriostasis and deodorization, and specifically to a manufacturing method of plant composite type efficient bacteriostatic deodorant based on HQ22 soybean extract. 
     2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98 
     In recent years, with the development of biotechnology, people&#39;s requirements for the quality of living environment are becoming more and more stringent. During the indoor storage of domestic garbage, a large amount of gas with pungent odor will be produced, which will not only pollute the surrounding air environment, but also adversely affect the health of residents. In developed countries such as Japan, biological deodorization is widely used in many families. The principle of biological deodorization is to use the efficient decomposition ability of microorganisms to decompose smelly harmful substances into non-toxic and harmless substances. Compared with the most popular fragrance masking method in China, biological deodorization is obviously more scientific, safe and environmentally friendly. 
     However, due to market reasons, some biological deodorization products, which are in pursuit of effectiveness, are mostly added with a large number of harmful chemical components to promote the decomposition efficiency of microorganisms. unfortunately, chemical component residues can easily pollute indoor air, and such components have no peculiar smell but are harmful to human body after long-term contact, so it is difficult to detect them in ordinary families without professional detection tools. 
     Therefore, a safe, harmless, and environment-friendly, high-efficiency plant composite biological bacteriostatic deodorant which can not only phagocytize and decompose odor and bacteria, but also inhibit the reproduction of surrounding bacteria will have a good application prospect in the field of bacteriostatic deodorization.

     Performance Tests 
     The test method of bacteriostatic effect in the implementation case is as follows: as the common microorganisms in municipal household garbage are  Escherichia coli, Flavobacterium  and mold, the bacteriostatic test takes these four strains as test objects; and the specific operation is as follows: 0.1 mL of bacteriostatic deodorant in the implementation case is coated on a flat plate; samples were put on filter paper, dried and put on the plate coated with indicator bacteria, and cultured for 24 h to measure the diameter of inhibition zone. 
     The test method of deodorization effect in the implementation case is as follows: as the common odor sources in municipal household garbage are ammonia and hydrogen sulfide, the deodorization test takes these two odor sources as test objects; and the specific operation is as follows: putting the bacteriostatic deodorant into a 50 ml sprayer and spray it into a 2500 ml experimental bottle; spraying 7 times, counting 1 ml; stirring to evenly distribute the gas, and detecting the odor concentration after 20 min.
