Problems solved by technology

At present, the uniformity of heating is one of the main factors restricting the application of radio frequency. Uneven heating will lead to incomplete disinfection of some soils, decrease in the mortality of pathogens and pests, reduce the treatment effect, and even cause disinfection failure.

Abstract

The invention relates to a partition intermittent soil radio frequency disinfection device and a control method, including a radio frequency generator, a matching device, a converter, an electrode and a shielding box, a control system and a cooling system; the radio frequency generator is connected to the matching device through a coaxial cable, The RF generator transmits the generated RF signal to the matcher; the matcher is connected to the RF generator at one end of the coaxial cable, and the converter at the other end; the electrodes are set in a grounded shielding box, and the electrodes are covered with soil ; The converter is connected to the electrodes in the shielding box through cables, and the electrodes transmit the radio frequency energy to the soil. The invention divides the soil into several soil areas by arranging several pairs of electrodes at the same time, and only one pair of electrodes works each time, and the cycle intermittent heating improves the uniformity of soil temperature distribution, effectively kills insects and bacteria, and improves the treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural soil continuous cropping obstacle treatment, in particular to a partition intermittent soil radio frequency disinfection device and a control method. Background technique [0002] In recent years, due to the large-scale cultivation, specialization, and facilities, soil continuous cropping obstacles have become more and more serious, which has become a prominent problem restricting the sustainable development of agriculture, usually resulting in 10% to 40% yield loss, and more than 60% or even no harvest in severe cases. Soil treatment before planting is the most effective way to prevent continuous cropping obstacles, and it is also an important measure to reduce the amount of chemical pesticides and increase efficiency. In addition to agronomic measures (crop rotation and stubble inversion, grafting, and fine varieties), soil treatment technologies currently mainly fall into three categories:...
