Sugarcane is one of the important raw materials for sugar production in China. The cultivation and breeding of sugarcane is mainly based on asexual reproduction of seed stems. Its growth is divided into germination stage, seedling stage, tillering stage, elongation stage and mature stage. Cultivation and breeding are carried out before the tillering stage Seedling hardening can greatly improve the survival rate of sugarcane. When sugarcane grows 5-6 leaves at the seedling stage and enters the tillering stage, it needs to be transplanted in the field to make it continue to grow in the land, and the demand for water in the growth stage of sugarcane The amount is lower in the germination stage, seedling stage, and maturity stage, and the water demand in the tillering stage and elongation stage is higher, and the demand for nutrients is also higher.
