Automatically controlled microwave soil disinfecting device and soil disinfecting method

Abstract

The invention provides an automatically controlled microwave soil disinfecting device and a soil disinfecting method, relating to a device for preventing the soil from transmitting plant diseases andinsect pests. In order to solve the problems such as microwave leakage to endanger human body health, deficient microwave penetration depth, bad microwave field uniformity, and the like, in the existing microwave soil disinfecting method, the invention provides the automatically controlled and unpiloted microwave soil disinfecting device and the soil disinfecting method. The device comprises an automatic tracking finding and unpiloted trolley, a navigation belt of the trolley, a photoelectric sensor, a microwave generator, a microwave transmitting cover and a heat preservation layer. The method comprises the following steps of: disinfecting the soil before planting crops; piling the soil to be disinfected into ribs with bottom width of 25-60cm and distance of 10cm; slowly driving the trolley over the ribs; heating the temperature of the soil to be more than 70 DEG C with microwave; disinfecting harmful microorganism; and preventing the soil from transmitting the plant diseases and theinsect pests. The soil disinfecting method is high effective and environmentally friendly, and has no electro magnetic radiation, pollution and residue.

Description

technical field [0001] The invention relates to an automatically controlled microwave disinfection soil device and a soil disinfection method. Background technique [0002] Crop diseases and insect pests are one of the main natural disasters faced by human beings. It has the characteristics of various types, great impact and frequent outbreaks. The loss of fruit trees and vegetables due to pests and diseases is about 15-20% in the world every year. Since the 1950s in my country, the occurrence area of ​​major crop diseases and insect pests has been increasing, especially since the early 1970s, the occurrence area and frequency of diseases and insect pests have increased year by year, which has become the main restrictive factor for the development of high-yield, high-quality, and efficient agriculture in my country. [0003] At present, chemical pesticides are mainly used to control pest disasters. Due to the long-term and large-scale use of pesticides, the air, water, soi...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing method of using chemical reagents such as methyl bromide to disinfect soil pollutes the environment and endangers human health, and the existing microwave disinfection soil patents have microwave leakage that endangers human health, insufficient microwave penetration depth, and microwave field In order to solve problems such as poor uniformity, an automatically controlled and unmanned microwave disinfection soil device and a soil disinfection method are provided. It has the advantages of high efficiency and environmental protection, no electromagnetic radiation hazard to people, and no pollution and residue to the environment. It can make microwave disinfection Technology becomes practical
