How to apply fertilizer to ensure high yield during the flowering period of rice, there are different degrees of disasters in the mainstream rice producing areas. The drought in the south is serious, and the heavy rain in the northeast is bound to affect the output of food crops. While doing a good job of disaster relief, rice production areas should pay attention to the management of water and fertilizer in the stage of heading and flowering. The quality of water and fertilizer management directly affects the size and yield of rice panicles.
After rice heading and flowering, the field with insufficient application of medium-term panicle fertilizer or no panicle fertilizer should be topdressed with nitrogen fertilizer at the beginning of heading, and combined with phosphorus and potassium fertilizer. Foliar fertilization can not only solve the problem of weak root-fertilizing ability in the late growth stage of rice, but also high and fast fertilizer efficiency. It is necessary to pay attention to the selection period of time during rice flowering stage, so as not to affect flowering pollination.
