What fertilizer makes sugarcane sweetest and grow tall and fast

SummaryBase fertilizer: apply 1500-2000kg of decomposed farmyard manure and 20-30kg of compound fertilizer per mu. Seedling-promoting fertilizer: apply 5kg of high-nitrogen water-soluble fertilizer per mu. Tillering fertilizer: apply 5kg of high-nitrogen water-soluble fertilizer per mu. Stem-promoting fertilizer: apply 5kg of high-nitrogen water-soluble fertilizer per mu. Tail-strengthening fertilizer: apply 5-10kg of high-calcium potassium water-soluble fertilizer per mu.

1. What fertilizer makes sugarcane grow sweet and thick

1. Base fertilizer

Apply 1500-2000kg of decomposed farmyard manure and 20-30kg of compound fertilizer per mu, generally after plowing the land.

2. Seedling-promoting fertilizer

Sugarcane has a high demand for nitrogen fertilizer during the seedling stage. Sufficient nitrogen helps promote the robust growth of sugarcane seedlings and roots, and also benefits the leaves. Generally, a high-nitrogen water-soluble fertilizer can be chosen, with a dosage of 5kg per mu.

3. Tillering fertilizer

During the tillering stage, sugarcane needs a topdressing of high-nitrogen potassium fertilizer, such as a water-soluble fertilizer series, with a dosage of 5kg per mu, which helps promote sugarcane tillering and improves sugarcane growth.

4. Stem-promoting fertilizer

The rationality of nutrients during the sugarcane stalk growth period has a very important impact on yield. At this time, nitrogen fertilizer needs to be applied as topdressing; a high-nitrogen water-soluble fertilizer can be chosen, with a dosage of 5kg per mu, which can also play a role in lodging resistance.

5. Tail-strengthening fertilizer

During the tail-strengthening period, sugarcane can be given a high-calcium potassium water-soluble fertilizer, which helps increase sugarcane sweetness and speed up maturity. Generally, fertilization can be carried out about 2 months before, with a dosage of 5-10kg per mu.

2. Precautions for fertilizing sugarcane

Fertilizer needs to be applied in small amounts multiple times. During sugarcane topdressing, flushing application and drip irrigation can be adopted, using water to carry fertilizer to promote rapid and efficient nutrient absorption.

3. Growth habits of sugarcane

1. Sugarcane is a crop that prefers warmth and light. The annual accumulated temperature needs to be 5500℃-8500℃, the frost-free period is more than 330 days, the average annual air humidity is 60%, the annual precipitation requirement is 800-1200mm, and the sunshine duration is more than 1195 hours.

2. Based on sugarcane growth and yield formation, as well as the relationship between sugar content and climate, the active accumulated temperature with a daily average temperature of ≥20℃ is proposed, as well as limiting whether sugarcane overwinters.

3. There is also the annual extreme low temperature (Tm), the main limiting factor for perennial growth, used as an indicator for sugarcane climate zoning, mainly divided into the following 4 sugarcane planting climate zones.

4. An accumulated temperature above 5000 ℃ and Tm ≥-2℃ is a relatively suitable planting climate zone; an accumulated temperature of 4000-5000 ℃ and -5℃ ≤Tm ≤-2℃ is a suitable climate zone; an accumulated temperature of 3000-5000 ℃ and -5℃ ≤Tm ≤-2℃ is a marginally suitable climate zone; an accumulated temperature of ≥3000-4000 ℃ and -8℃ ≤Tm ≤-2℃ is a plantable climate zone.

5. These 4 sugarcane planting climate zones are mainly concentrated in the mid-subtropical, south-subtropical, and tropical monsoon climate zones. Among them, the relatively suitable planting climate zones are basically all located south of 24° north latitude.
