Precautions:

According to soil fertility and water conditions, determine the appropriate sowing amount. If the soil conditions are poor, the sowing amount should be increased.

To ensure the appropriate planting density, it is generally appropriate to use 25,000 ~ 30,000 plants/mu.

Check the seedlings in time to fill the density gap, sooner rather than later.

Ensure the smooth flow of the three ditches and do a good job in the prevention and control of Sclerotinia sclerotiorum at flowering stage.
