Description
Technical field
The utility model relates to insect disinfestation device, is a kind of microwave rotovator of killing root-knot nematode.
Background technology
Root-knot nematode extensively distributes in the whole world, and host range is extensive, and hazard of plant is serious, after disease takes place, and the general underproduction about 10%, serious in more than 75%, it can make fungi and bacterium be easy to infect plant simultaneously, is one of major reason of inducing plant disease.On protection ground,, be main always with chemical agent for the control of root-knot nematode; Along with the chemical sproof increase of root-knot nematode to chemical agent; The chemical agent that uses at present is highly toxic pesticide basically, kills the tie lines worm with these chemical agents environment is caused severe contamination, simultaneously; Plant is had very high medicament residue property, is the main root that " malicious vegetables " produce.For this reason, the art technology people attempts to develop pure physical method and kills the tie lines worm.For example: the vexed canopy method of high-temperature steam, water logging method etc., still, all there is the deficiency of cost height, complicated operation in these methods, can not promote the use of so far.With the microwave device desinsection also is a kind of pure physical method, but these disclosed microwave desinsection devices can only be killed the parasite in 12 centimetres, bacterium etc. in the soil.And the characteristic distributions of root-knot nematode be in 30 centimetres in soil with the interior degree of depth, and root-knot nematode has extremely strong fertility, every female adult worm 300-800 grain of once laying eggs year is sent out the generation for 5-10, the situation that condition is suitable can be bred a generation in following about 17 days.Therefore, existing microwave desinsection device all can't be killed root-knot nematode.
The utility model content
The purpose of the utility model is, a kind of microwave rotovator of killing root-knot nematode is provided, and when rotary tillage soil, successively 30 centimetres in soil all killed with interior root-knot nematode continuously, makes eradicative rate reach 100%.
The utility model is for realizing above-mentioned purpose, and realize through following technical scheme: a kind of microwave rotovator of killing root-knot nematode comprises flat frame; The front end of frame 1 is provided with road wheel, and middle part, frame bottom surface connects rotary blade, and the periphery of rotary blade is provided with the microwave irradiation chamber; Microwave irradiation chamber shape of cross section is hemispherical, and the bottom is uncovered, and the microwave irradiation chamber is connected with frame; On the anterior outer wall in microwave irradiation chamber several first microwave emitters are installed, several first microwave emitters are distributed on the width in microwave irradiation chamber, and arrange in the horizontal direction; Several second microwave emitters are installed on the outer wall of rear portion, microwave irradiation chamber; Several second microwave emitters are distributed on the width in microwave irradiation chamber, and arrange in the horizontal direction, the corresponding site of microwave emitter is installed on the wall in microwave irradiation chamber is offered the microwave scattering through hole respectively, and both sides, top, microwave irradiation chamber are offered first row's ventilation hole and second row's ventilation hole respectively; First row's ventilation hole and second row's ventilation hole are distributed on the width in microwave irradiation chamber; Its diameter is the 1-2 millimeter, and pitch of holes is the 2-2.5 millimeter, and rotary blade is connected with motor through worm and gear and gear.First microwave emitter and second microwave emitter are 4-6.The diameter of first row's ventilation hole and second row's ventilation hole is 1.2 millimeters, and pitch of holes is 2.5 millimeters.The dividing plate of being made by mica material is installed in each microwaves corresponding through hole on the inwall in microwave irradiation chamber, and the thickness of dividing plate is the 2-3 millimeter.The frequency of described microwave emitter is 915MHz, the speed of travel of microwave rotovator be 0.4-0.8 rice/minute.
The described microwave rotovator of the utility model is when rotary tillage soil, to kill root-knot nematode with the microwave continuous irradiation, and rotovator is in walking, and rotary blade is all translated into the upper strata with 30 centimetres with interior soil continuously; Simultaneously; Because microwave emitter is distributed in the front and rear of hemispherical microwave irradiation cavity, and arrange 4-6 at least in horizontal direction, all inserted in the microwave irradiation scope when soil has been revolved by rotary blade; Thereby thoroughly kill root-knot nematode, eradicative rate has reached 100%.
The described rotovator of the utility model is remarkable through trial effect: the described rotovator of the utility model carries out in planting the winter warm type green house of cucumber year after year, and 900.0m is taken up an area of in test
2, this inner greenhouse ground gesture is smooth, and water and fertilizer management is consistent, and root knot nematode disease takes place serious throughout the year.Find cucumber poor growth, short and small, the leaf color anomaly of plant in the whole booth in the preceding stubble cucumber growth process, the spherical root nodules that differ in size in a large number appear in root, get these root nodules and carry out finding in it a large amount of root-knot nematodes are arranged behind the microscopy.This batch cucumber is pulled out and gets in this booth the dark soil of 0-30cm behind the garden and carry out root knot worm and extract test, finds that root-knot nematode is distributed in 30 centimetres of soil depth with interior scope, the density maximum 3-10cm with interior soil horizon in, soil moisture content is between 12%-25%.With microwave rotovator Continuous irradiation when the rotary tillage soil, the microwave rotovator speed of travel be 0.5-1 rice/minute, microwave frequency is 915MHz.This experimental field is divided into 15 sub-districts, each sub-district area 60.0m
2, the extraction of its experimental field is at random.Each minizone is provided with mark line, and disposable over-shoes will be in time changed in operation between different districts, and the shoe cover of changing will be placed on separately in the Object storing drum, with anti-cross infection.Rotovator detects soil in walking irradiation back; Respectively get 100g appearance soil respectively from the depths of soil 5cm, 10cm, 20cm, 30cm; With the 100g that takes a sample again at random behind its abundant mixing; Extract the root-knot nematode in the soil with sucrose gradient centrifugation, dyed back microscopy, the lethality of root-knot nematode is 100%.
Soil by microwave irradiation after to the influence of following batch raise crop test: test used cucumber seedling and educate by aseptic nutrition earth culture; Cultivation method and way to manage are all carried out according to routine in the process of the test, observe the cucumber growing way through 45 days and draw: the soil of killing behind the root-knot nematode with the described microwave rotovator of the utility model does not have influence to second stubble crop.
