Background
Various nematodes are used, for example, root-knot nematodes, cyst nematodes, root rot nematodes and other nematodes can cause irreversible root damage to crops such as tomatoes, soybeans, wheat, watermelons, tobacco, potatoes, corns, carrots and the like, so that the yield of the crops is greatly reduced. Such as plant root-knot nematodes: (Meloidogynespp.) is a type of nematode with the widest distribution, the most variety and the most serious harm among plant pathogenic nematodes, and host plants of the nematode are more than 3000 (Jia Chang et al 2011), and specifically comprise soybean root-knot nematodes, corn root-knot nematodes and the like; (iii) Soy bean cyst nematode: (Heterodera glycines) Is the most important plant disease on soybeans, occurs in soybean planting areas of 18 provinces in China, generally causes the yield reduction of soybeans by 5-10 percent, reduces the yield reduction of soybeans by 30-50 percent in serious cases, even gives up the crop in individual years, and seriously restricts the production safety of bean crops (Roning, etc. 2019)And also soybean root knot nematodes and the like which cause serious damage to the legume crops; the wheat cyst nematode is a worldwide important nematode disease which is harmful to cereal crops such as wheat, barley, oat and the like, and the pathogen is the cereal cyst nematode (Heterodera avenae) Heterodera filipjevi: (H. filipjevi) And thalassosporangium (1) (ii)H. latipons). At present, the wheat has been reported to occur in 16 provinces and cities in China, the wheat covers the main production area of all wheat in China, and the disease area reaches more than 6000 million mu (Cui et al 2015). Yuanyxia et al (2014) research reports that second-instar larvae of cyst nematodes invade wheat roots 2 weeks after wheat seedlings emerge in Henan, and when the content of cysts in soil is more than 10 eggs/g soil, the yield loss of wheat reaches 16-55% (Housheng et al, 2012), and similarly, the wheat root rot nematodes are one of the common nematode diseases of wheat.
In the research of nematodes, the identification of plant nematode resistance through field experiments is a common mode, and the basic operation is to sow a plurality of crop varieties after ditching in a test field, so that the planted crops are infected by nematodes, analyze and identify the nematode resistance of the variety crops, and finally obtain resistant varieties and excellent germplasm resources and genetic materials.
According to the existing plant nematode field resistance identification experiment, due to the fact that the involved land is small, the varieties of crops are multiple, the planting requirements among the varieties and the design requirements of the experiment and production planting, such as ditching depth, spacing and the like, are different, and different varieties of crops have different experimental requirements, such as seeding quantity and the like, the modern ditching machine in the prior art cannot be used in the experiment, only manual ditching can be conducted, but the operation efficiency of manual ditching is low, meanwhile, the use pertinence of corresponding tools, such as plows, rakes and other agricultural tools is poor, and the use is very inconvenient.
