What is the sweetest fertilizer for sugarcane (grows high and fast)

Base fertilizer: per mu of rotten farm manure 1500-2000kg, compound fertilizer 20-30kg. Seedling raising fertilizer: high nitrogen water soluble fertilizer 5kg was applied per mu. Tillering fertilizer: high nitrogen water soluble fertilizer 5kg was applied per mu. Stem fertilizer: high nitrogen water soluble fertilizer 5kg was applied per mu. Strong tail fertilizer: high calcium and potassium water-soluble fertilizer 5-10kg per mu.

What kind of fertilizer is applied to sugarcane to make it sweet and sturdy

1. Base fertilizer

The application of rotten farm manure 1500-2000kg and compound fertilizer 20-30kg per mu is generally required after ploughing the land.

2. Raising seedling fertilizer

Sugarcane has a high demand for nitrogen fertilizer in the seedling stage, sufficient nitrogen is conducive to promote the robust growth of sugarcane seedlings and roots, but also helpful to leaves, generally can choose high-nitrogen water-soluble fertilizer, the amount of 5kg per mu.

3. Tillering fertilizer

Sugarcane needs to be topdressing high nitrogen potassium fertilizer at tillering stage, such as water soluble fertilizer series, the amount of 5kg per mu is beneficial to promote sugarcane tillering and improve sugarcane growth at the same time.

4. Attack stem fertilizer

The rationality of nutrients in the growing period of sugarcane stalk has a very important effect on the yield. At this time, we need to topdressing nitrogen fertilizer, can choose high nitrogen water-soluble fertilizer, the amount of 5kg per mu of land, but also can play a role in lodging resistance.

5. Strong tail fat

In the strong tail stage, sugarcane can choose to apply high calcium and potassium water-soluble fertilizer, which is beneficial to increase the sweetness and accelerate the ripening of sugarcane. The general fertilization can be carried out in the first two months, and the amount of fertilizer per mu is 5-10kg.

Matters needing attention in fertilization of sugarcane

A small amount of multiple fertilization is needed. In the process of sugarcane topdressing, irrigation and drip irrigation can be adopted to promote the rapid and efficient absorption of nutrients with water and fertilizer.

III. Growth habits of sugarcane

1. Sugarcane is a mild and light-loving crop, with an annual accumulated temperature of 5500 ℃-8500 ℃, a frost-free period of more than 330 days, an average annual air humidity of 60%, an annual precipitation of 800-1200mm, and sunshine hours of more than 1195 hours.

2. According to the growth and yield formation of sugarcane and the relationship between sugar content and climate, the active accumulated temperature of daily average temperature ≥ 20 ℃ was proposed to limit whether sugarcane overwintered or not.

3. As the index of sugarcane climate division, the annual extremely low temperature (Tm), which is the main limiting factor of perennial growth, is mainly divided into the following four sugarcane planting climate zones.

4. The accumulated temperature is more than 5000 ℃, Tm ≥-2 ℃ is the suitable climate area, the accumulated temperature is 4000-5000 ℃,-5 ℃ ≤ Tm ≤-2 ℃ is the suitable climate area, the accumulated temperature is 3000-5000 ℃,-5 ℃ ≤ Tm ≤-2 ℃ is the sub-suitable climate area, the accumulated temperature is ≥ 3000-4000 ℃,-8 ℃ ≤ Tm ≤-2 ℃ is the planting climate area.

5. The four sugarcane planting climate regions are mainly concentrated in the mid-subtropics, south subtropics and tropical monsoon climate regions, among which the more suitable climate areas are basically located in the south of 24 °N latitude.
