Description

Technical Field

[0002] Field test technology refers to the general term for various tests with crops as the research object under field conditions. Since field tests are carried out under natural soil and climate conditions in the field, which are most similar to the field production conditions, the test results can be directly demonstrated and promoted in large fields under similar production conditions.

[0003] The planning of field experimental plots needs to be marked with lime materials to specifically plan the area to achieve the test effect. For the planning of field experimental plots, a cart-like device is basically used to make the lime materials fall naturally, and manual pushing is used to achieve the effect of marking and dividing the areas of the experimental plots. However, this marking method by manual pushing will result in inaccurate marking and the lime lines being curved, thus causing deviations in the planning of field experimental plots.
