Sugarcane is an important economic crop and one of the main raw materials for the sugar industry. 80% of sugarcane grown in my country is dry slope land, the soil is mostly barren, and the organic matter content is low, generally about 1%. Therefore, adding fertilizers rich in organic matter as base fertilizer has a very good effect on increasing yield and improving soil.

The experience of high-yield fertilization for sugarcane shows that the base fertilizer should be mainly bio-organic fertilizer, combined with nitrogen, phosphorus, and potassium fertilizers. In general spring sugarcane high-yield fields, 200-300 kilograms of biological organic fertilizer per mu is used as base fertilizer, 10 kilograms of urea, 20 kilograms of superphosphate, and 10 kilograms of potassium sulfate are applied. When applying basal fertilizer, first open a planting furrow, apply bio-organic fertilizer to the bottom of the furrow, and then apply inorganic fertilizer on both sides of the furrow. Top dressing fertilizer, tiller fertilizer, and stem fertilizer are applied at three stages. When sugarcane seedlings have two leaves and one heart, apply attacking seedling fertilizer, apply 20 kg bio-organic fertilizer per mu, and apply more for weak seedlings to achieve uniform and strong seedlings. If the base fertilizer and seedling fertilizer are sufficient and the seedlings grow vigorously, it can be applied once during the tillering period, which is called strong tiller fertilizer.

If the base fertilizer is insufficient, the seedling fertilizer is not much, and the sugarcane seedling grows poorly, the tiller fertilizer can be applied twice. The first time is at the beginning of tillering, that is, when the main seedling has 6-7 true leaves, and 20 kg of bio-organic fertilizer is applied per mu; the second time is applied at the peak of tillering, that is, when the main seedling has 10-11 true leaves. , Apply 40 kg of bio-organic fertilizer per mu, and then cover the fertilizer with soil. Stem fertilizer should be reapplied with 50 kg of bio-organic fertilizer.

Appropriate more application for sugarcane fields with poor soil quality and fertility. Autumn planting sugarcane has many effective stems, long growth period, large growth, and more fertilizer. The total amount of fertilizer absorption is about 30-40% more than that of general spring planting sugarcane. Therefore, sufficient base fertilizer must be applied to fully develop autumn planting High yield performance of sugarcane.
