Instant-spraying-and-control multi-blocking-and-controlling green degradable foam base solution and application thereof in treatment of foul smell of polluted soil

The invention belongs to the technical field of foul smell treatment and control of polluted sites, and particularly relates to an instant-spraying and instant-control multiple-resistance-control green degradable foam base solution and application thereof in treatment of foul smell of polluted soil. The invention provides an instant-spraying instant-control multiple-resistance-control green degradable foam base solution. The instant-spraying instant-control multiple-resistance-control green degradable foam base solution is prepared from 6-10 parts of vegetable protein, 1.5-2 parts of an odor absorbent, 2-4 parts of a first surfactant, 0.2-0.4 part of a first stabilizer and 83.6-92.3 parts of water. According to the invention, the vegetable protein and the peculiar smell absorbent are compounded with the first surfactant and the first stabilizer at the same time, so that the spray-control and multi-blocking-control green degradable foam is formed, the problems that the existing foul smell dissipation control m
