How to fertilize the latest sugarcane
Sugarcane is a well-known fruit, it is a stem fruit, rich in nutrients, rich in water and sugar needed by the human body, deeply loved by people. With the increase of market demand, its planting area is getting wider and wider, sugarcane has the characteristics of long growth period and large yield, which also represents its great demand for fertilizer. it can be directly said that the amount of fertilizer determines the sugarcane yield. Therefore, the fertilization of sugarcane is very important, so how to fertilize sugarcane? Let's take a look.
1. Characteristics of fertilizer requirement
The growing period of sugarcane is longer and the yield is higher. Generally, the yield per mu can reach 5-8 tons, and the high yield can reach 10 tons. It needs more nutrients during the whole growth period. According to research, for every 1 ton of sugarcane produced, it needs to consume 1.5-2 kg of nitrogen, 1-1.5 kg of phosphorus, 2-2.5 kg of potassium and 0.5-0.75 kg of calcium. In addition, the whole growth period of sugarcane can be divided into several stages, of which the fertilizer needed for the extension period accounts for 65% and 75% of the total growth.
2. Apply sufficient base fertilizer
Base fertilizer is generally applied before planting, mainly organic fertilizer, combined with chemical fertilizer, can improve the sufficient nutrient growth of sugarcane buds, generally apply 1500-2000 kg of rotten organic fertilizer per mu, and match 20-30 kg of compound fertilizer. Spring planting sugarcane can be applied in holes, and then inorganic fertilizer can be applied on both sides, while winter planting sugarcane can be used as cover fertilizer, which can cover the soil after fertilization, so that the sugarcane buds can survive the winter safely.
3. Fertilization at seedling stage
In order to make sugarcane tiller grow early and develop quickly, it is necessary to apply seedling fertilizer early in the seedling stage, which can promote the root growth of sugarcane buds, promote leaf growth and improve photosynthesis. Seedling fertilizer is recommended to use high-nitrogen compound fertilizer, when sugarcane seedlings grow 3-4 leaves, then use compound fertilizer 8-10 kg per mu, which can be applied with water hole, or in middle ploughing and weeding is soil application, but it should be applied with water hole in case of drought. When the seedlings tiller, at this time in order to tiller sturdy, to apply strong tiller fertilizer, generally use high nitrogen and high potassium compound fertilizer, per mu use 8-15 kg, and seedling fertilizer, water or soil application.
4. fertilization in the middle and later stage of growth.
The middle stage of sugarcane is mainly the elongation period, when the stem grows rapidly, and it is also the key point to increase yield, so fertilization must be re-applied. Generally, in the early and peak elongation period, 15-20 kg of high nitrogen compound fertilizer per mu was used, combined with medium tillage to promote root growth and improve root absorption capacity. In the later stage, the main purpose of fertilization is to cultivate the underground sugarcane buds and lay a good foundation for the persistent root of the following year. Generally, the strong tail fertilizer is applied once two months before maturity, and the compound fertilizer is used 5-8 kg per mu.
The above is the introduction of how to fertilize sugarcane. I hope it can help you. If you want to know more about it, please follow us.
