What is the correct application method for rice flower-promoting fertilizer?
How should rice flower-promoting fertilizer be applied? Please guide. Rice flower-promoting fertilizer and flower-preserving fertilizer are collectively called ear fertilizer. Flower-promoting fertilizer is generally applied from the 4th leaf from the top to the 3rd leaf from the top stage of rice. The 4th leaf from the top to the 3rd leaf from the top stage is a reverse leaf age stage. For early-maturing late japonica rice, it is generally applied when the first internode has reached its final length and the second internode is elongating. Flower-promoting fertilizer should be applied according to the seedlings. High-yield fields generally do not apply flower-promoting fertilizer. Only fields with small population growth and obvious yellowing at the early stage of jointing and ear elongation should be topdressed with an appropriate amount. Fields with little base fertilizer, a small population, and obviously faded leaf color should be applied early; fields with sufficient base fertilizer, a large population, and no yellowing of leaf color should be applied less or not at all.
