Ground sterilisation and evaporation preventing process - uses wheeled vehicle to loosen and spray first with sterilising and then with sealing agent

摘要

The ground sterilisation process loosens the ground and sprays a sterilisation agent into it in metered quantities. To prevent evaporation or emergence of the agent, the ground is then sprayed with a sealing agent. The ground can be smoothed after spraying with the sterilisation agent and before sealing. The machine used can be mounted in a frame (10) towed by or mounted on a tractor, having a cultivating tool (20) followed by a first sprayer (30) for the sterilising agent which is supplied from a storage tank (35). This is in turn followed by a second sprayer (130), also supplied from a tank, for the sealing agent.
