Seedling stage: use 0.3mg/L (1.3kg water for each grain) solution spray once, or spray it once respectively in seedling stage and growth stage (2 times in total), which can promote the growth of sugarcane. Increase the effective number of stems per mu by 1.37%, increase stem length by 6.75%, increase stem thickness by 2.9%, increase stem weight by 9.72%, increase yield by 35kg/mu, and significantly increase sugarcane sugar content.

      Tillering and node drawing stage: use 0.01~0.04mg/L (4~10kg water for each granule) solution spray, which can significantly increase production and sugar.
