As one of the top killers of common soil-borne diseases, nematodes are extremely harmful to agriculture. It is almost "invisible" with a length of only 0.3-6mm, but it is related to more than 50% of soil diseases. A variety of nematodes reduce the agricultural industry in related fields by 5%-20%, and partially reduce production by 60% or even no. Therefore, it is imperative to strengthen the detection and control of soil nematodes. At present, soil nematodes are inspected, and each inspection unit uses a nematode separator .
Nematode disease has almost no significant features, and it is similar to deficiency syndrome in the field, mainly due to plant growth weakness, short stature and yellowing, and decreased yield, so it is easy to be confused with other pathogenic diseases, which leads to the inability to prescribe the right medicine, thus the agricultural economy is affected. Serious challenge. Therefore, to carry out prevention and control of nematode disease, it is necessary to strengthen the detection of nematodes, prevent in advance, and target prevention. The nematode separator can soak and separate the nematodes in the soil. It is the principle that the nematodes must move on the water film. The atomizer produces water mist attached to the surface of the plant to form a water film. The nematodes rely on the water film to move, and the water film is continuously thickened to form water. Beads, thereby separating the nematodes. The mist generated by the atomizer provides sufficient oxygen to ensure the survival rate of the nematode. The isolated nematode is very clean and basically free of impurities. The micro-injection of the insect can be microscopically examined, and the operation is convenient, and 12 plant samples can be separated at the same time. The nematode is highly efficient.
At present, from the perspective of development, nematodes are very concealed and difficult to detect. Only when the disease develops to a certain extent, the symptoms will be manifested in the upper part of the earth. At this time, the root damage has been very serious, and it is difficult to control the application of the drug. Compared with traditional fungi, bacteria, viruses and other diseases, soil nematode diseases are difficult to control and lack effective prevention and control methods, and may rise to the main diseases in the future. Therefore, in this case, strengthening detection and prevention is the key, and the use of nematode separators can help early detection of nematode diseases in the agricultural field, guide targeted drug control, and fundamentally eliminate the threat of nematode diseases.
