Auxiliary device of nematode fungi to plant nematode predation rate is preyed on to survey

The utility model discloses an auxiliary device of nematode fungi to plant nematode predation rate is preyed on to survey, include disk body big or small with the culture dish, the shape adaptation, the up end of disk body is connected with the eager pipe that is used for surely getting the culture medium, and the up end of disk body is provided with at least two and sets up the female through -hole, and every through -hole is the same to the distance of surely managing, and the through -hole winds the surely center pin evenly distributed of pipe, and the circumference evenly distributed who surely manages is followed to the through -hole, the threaded piece of the equal threaded connection of every through -hole, and the screw element reciprocates along the length direction of through -hole, this auxiliary device of nematode fungi to plant nematode predation rate is preyed on to survey can be very effectual scratches the culture medium and forms empty white area and in order to place the nematode, meanwhile,
