"Stable seedling" fertilizer accounted for 2%, and the use of pure nitrogen 0.15 kg, phosphorus pentoxide 0.1 kg, potassium oxide 0.19 kg.

“Plate fertilizer” accounted for 28%, and the use of pure nitrogen was 1.5-1.5 kg, phosphorus pentoxide was 14 kg, and potassium oxide was 2-7 kg. “Post-filling” means using 0.1% boron fertilizer solution at the beginning of the flowering stage and the end of the flowering stage, adding 0.1% potassium dihydrogen phosphate (content 96% or more) solution, and spraying 50-60 kg per mu.

Pick up the tip in time. When the rape grows to 30-40 cm, start picking the tip. Generally, the length of the picking tip is about 10 cm, and the growth length is slightly longer than that of the sharp picking tip, and the opposite is short. If you have early flowers, you can take the same method. Generally, the length of the early flower picking tip is 20-25 cm. It is better to have the length of the early flower picking point 8-10 cm after the year. At the same time, pay attention to the pest control in each period.
