Soil processing method

Abstract

The soil processing method of the invention comprises the steps of slipping a microwave radiator into soil and then radiating microwaves to the soil that becomes a processing subject from the microwave radiator. In this case, methods for slipping the microwave radiator into soil that may be employed include one for slipping a submarining body containing a microwave radiator while driving a farm implement by a submarining pawl mechanism similar to a chisel or subsoil, another for vertically thrusting it into or pulling it out of soil by a power arm, and another for vertically thrusting it into or pulling it out of soil by utilizing various vertical excavating devices. According to the invention, it is possible to effectively apply the influence of microwaves to the soil in a deep region that can hardly be influenced by microwave radiation directed to the surface of a paddy field. Thereby, it is possible to expect various agriculturally useful influences, for example, plant growth adjustment, germinal time adjustment, soil disinfection, and soil improvement.

Description

technical field [0001] The present invention relates to an agricultural soil treatment method used for the purpose of expelling nematodes, crop growth regulation, germination period regulation, soil improvement, etc., and particularly relates to a soil treatment method using microwaves. Background technique [0002] Conventionally, the inexpensive method used for disinfection of bed soil of vegetables and flowers, seedbed disinfection of leafy vegetables, and soil disinfection of facility vegetables has been to widely use a simple and highly effective chemical called "methyl bromide". However, according to the "Montreal Protocol on Substances Related to Depleting the Ozone Layer" adopted by the parties to the Vienna Treaty in 1987, they agreed to restrict the use of this methyl bromide. bromide. [0003] In order to adapt to this situation, attempts have been made to develop a soil disinfection technology to replace this methyl bromide, as representative alternative technol...

Problems solved by technology

In fact, although for the soil in a relatively shallow area (for example, from the ground to a depth of about 10 cm), the reaching temperature increases corresponding to the output power, but in the depth area above it, even if the output power is increased , also does not reach the target temperature
