PROBLEM TO BE SOLVED: To enable chemicals to be ejected into soil at a short interval. SOLUTION: The soil-disinfecting machine 1 has a machine body 2 constituted so as to freely travel in a field, and equipped with a chemical tank 6 storing a chemical B, chemical pumps 7 for sucking the chemical B in the chemical tank 6, a pump-driving mechanism 8 for driving the chemical pumps 7, and an injection blade 10 for ejecting the chemical B ejected from the chemical pump 7 into the soil. Two or more of the chemical pumps 7 are installed therein. The pump-driving mechanism 8 is constituted so that a plurality of the chemical pumps 7 may be driven one by one. The injection blade 10 is constituted so as to send the chemical B after gathering the chemical B ejected from a plurality of the chemical pumps 7 to one place. COPYRIGHT: (C)2009,JPO&INPIT
