1、 How many days to apply fertilizer

1. Growth period: during the growth and maintenance of safflower trees, certain fertilizer needs to be applied to ensure good growth. If there is a lack of fertilizer, there is not enough nutrition to grow, and the growth is naturally weak and not so strong. In the season of vigorous growth, if there is a demand for fertilizer, apply fertilizer about every half a month. The specific frequency can be adjusted according to the growth demand

2. Flowering period: before the flowering period comes, you can apply more fertilizer appropriately, apply fertilizer every 10 days or so, and accumulate enough nutrients for growth

3. Dormancy period: the temperature in summer and winter is extreme, which is just in the dormancy period. At this time, the growth is relatively slow and the fertilizer demand is less, so you can apply fertilizer for a long time, or do not apply fertilizer directly

2、 Fertilizer type

In different periods, the demand for nutrients is different, and the types of fertilizer applied are also different. When just planting, you can use dung cleaning water, and the concentration must be lower to prevent root burning caused by excessive concentration. In the growth period, there is a demand for various elements. We can mainly use farm fertilizer and add compound fertilizer appropriately. Before flowering, a little more phosphorus and potassium fertilizer can ensure the flowering
