When is the best time to fertilize rice?
When is the best time to fertilize rice? Please explain. Because the natural conditions, farming systems, production levels and fertilization levels vary greatly across the rice-growing regions of southern China, different fertilization methods also exist.

Generally, the base fertilizer accounts for 40%-60%; among the mid-stage topdressings, tillering fertilizer accounts for 30%, panicle fertilizer accounts for 50%, and grain fertilizer accounts for 20%. This method is mainly used for large-panicle, large-grain varieties of single-season hybrid mid-season and late rice with a longer growth period, and for fields with poor soil fertilizer retention capacity and insufficient fertilizer.
