However, it is very sensitive to the reaction between methyl bromide treated soil and alkaline soil, and is suitable for growing in soil with pH 5.5-6.0. The cold tolerance is poor, and the growth temperature is 20-25 degrees Celsius. The growth stopped below 15℃, and the leaves withered and fell off below 10℃.

2. Propagation method: propagate a bunch of safflower by sowing or cutting, so that more seeds can be sown. The sowing season in North China is not limited, and other areas are suitable in spring. A bunch of safflower blooms late, and it blooms from September to 65438+ 10 in spring. If you want to advance flowering or harvest seeds, you should sow in the greenhouse or hotbed in early March. Apply a small amount of base fertilizer to the seedbed, level the bed surface and water it, then sow it after water seepage, cover it with a thin layer of soil, and the seeds germinate 8- 10 days after sowing. It grows for about 100 days and blooms for about two months. Softwood cutting is more suitable in March-May or September-65438+1October, combined with terminal bud picking.
