Background technique

Rapeseed is a major economic crop in my country, and it is grown in many parts of the country. When rapeseed is mature, the rapeseed can be used to squeeze oil, which has higher economic benefits. Rape is also planted in the mountainous and hilly areas of southern my country, but the planting area is not very concentrated and tends to be planted in blocks. The planting area is large or small, and the planting ridge width and row spacing cannot be guaranteed. At the same time, my country's traditional rapeseed planting mode is artificial sowing. This method has great disadvantages. On the one hand, it requires more labor, time-consuming and labor-intensive, and the row spacing and density of artificially sowed rapeseed cannot be guaranteed. If the seedling emergence rate is low in the later stage, artificial thinning and transplanting to fill the seedlings are needed, and the work is more complicated. However, most of the rape planters at this stage tend to be large-scale and complex. They are generally driven by tractors. The overall size is very large. It is very difficult to plant in the southern mountainous and hilly areas. Although it can meet the planting requirements of general terrain, it is very important for southern my country.
