The panicle fertilizer was used twice and focused on the promotion of flower-fertilizer and the application of phosphorus, potassium and silicon fertilizers. (2) Water slurry management: When the number of stems per acre reaches 80% of the expected number of panicles, they should be graded and lightly pruned; in the middle and later periods, in addition to the shallow water layer during meiosis, general wetting irrigation should be performed.
