Description

Isolation device for herbicide in plant breeding field Technical Field The invention relates to the technical field of breeding fields, in particular to an isolation device for herbicide in a plant breeding field. Background The plant seed-cultivating field is a field specially used for breeding high-quality seeds of good varieties of crops in agricultural production. The key purpose of the method is to ensure the safety of seed for the next season and grain safety, and the method is a fundamental link of an improved seed breeding system. ‌ to prevent natural hybridization between different varieties, to ensure genetic purity of seeds, the seeds Tian Chang keep a certain isolation distance ‌ from other crop fields of the same kind. The seed raising field needs to use herbicide to weed the appointed field before breeding plant seeds, and part of herbicide drugs in the herbicide spraying process can drift to the nearby field along with wind to cause injury to plants in the field, so that isolation devices are needed to isolate and protect other fields, the size and the structure of the existing isolation devices are fixed, and the size of the existing isolation devices cannot be adjusted in a telescopic manner. Accordingly, there is a need to design a plant breeding field herbicide spacer that ameliorates the above-described problems.
