The demand ratio of nitrogen, phosphorus and potassium for sugarcane is about 1.5: 1: 2 during the whole growth period. Sugarcane has the most demand for potassium and nitrogen, and needs higher calcium.

Base fertilizer:

The base fertilizer should be mainly organic fertilizer, which is used in combination with chemical fertilizers, which can provide good conditions for the rapid growth of sugar cane buds, root elongation, early tillering and strong growth.

Miaofei:

The sugarcane seedling stage requires less fertilizer but urgent fertilizer demand, and the demand for nitrogen is large, followed by potassium and phosphorus.

Tiller:

Apply zinc or high nitrogen and high potassium compound (mixed) fertilizer (such as sugar cane special fertilizer 18-8-18), and apply it to the water hole like seedling fertilizer, and cultivate soil 10-12cm high.

Stem tapping:

Stem tapping fertilizer is the key to increasing sugarcane production, and must be re-applied. The main application of high nitrogen and potassium compound fertilizer is to promote the growth of sugarcane roots, enhance absorption capacity, and enhance lodging resistance.

Strong tail fat:

General-purpose compound (mixed) fertilizer, soil after application; early application of sufficient fertilizer, stable growth may not be applied.
