After the seedlings are grown, inter-seeding is carried out, removing the over-dense seedlings, weak seedlings and diseased seedlings, leaving the well-grown seedlings and replenishing the sparse and seedless places. The inter-seedlings can be used for people's consumption.

Third, the growth of weeding, deworming, fertilizer and watering: in the growth process of rapeseed should be timely weed removal.
