Sugar cane planting technology: how to plant sugar cane fertilizer good?

How to grow sugarcane and fatten it? Please analyze and introduce in detail that sugarcane has a long growing period and high yield. it generally produces 5-8 tons of sugarcane per mu and 10 tons in high-yield fields. It absorbs a lot of nutrients during the whole growth period and is one of the crops that require a large amount of fertilizer. The best fertilization period for sugarcane is seedling stage, tillering stage and extension stage. The detailed fertilization methods can be referred to the following methods: sugarcane planting base fertilizer: the base fertilizer should be mainly organic fertilizer, which can be used in combination with chemical fertilizer to create good conditions for rapid growth of sugarcane buds, root elongation and early and strong tillers. Generally, 1500-2000 kg of fully mature organic fertilizer is applied per mu, and 20-30 kg of general compound fertilizer (15-15-15) is added. When applied, planting sugarcane in spring opened a planting ditch, applied organic fertilizer to the bottom of the ditch, and then applied inorganic fertilizer on both sides of the ditch; winter planting sugarcane used organic fertilizer as cover fertilizer, and then covered with a layer of soil. Sugarcane seedling fertilizer: the sugarcane seedling stage needs less fertilizer but urgent fertilizer, and the demand for nitrogen is large, followed by potassium and phosphorus. Early application of seedling fertilizer not only promotes the growth of sugarcane seedlings and roots, but also promotes leaf growth, expanding leaf area and increasing photosynthesis, thus promoting early growth and rapid development of tillers; if insufficient fertilization, it will lead to short growth and poor development of seedlings and tillers, even if fertilizers are supplemented later, it will be difficult to recover, resulting in a decline in yield and quality. Seedling fertilizer is recommended to use high-nitrogen compound fertilizer, when sugarcane seedlings grow to 3-4 leaves, apply compound fertilizer 8-10 kg per mu. It should be applied directly in combination with ploughing and soil cultivation, or in the case of water, and in the case of drought. In addition, the lack of seedlings should be checked in time to make the population grow neatly. Sugarcane tiller fertilizer: tiller fertilizer should be determined according to the specific situation. If the basal fertilizer and seedling raising fertilizer are sufficient and the seedlings are strong, they can be applied at one time at the peak tillering stage, and the amount of fertilizer should be less; if the basal fertilizer is insufficient, the seedling raising fertilizer is not enough, and the seedling growth is weak, the amount of fertilizer should be increased and applied twice. Once in the early stage of tillering, in order to promote tillering, called attack tillering fertilizer. Once applied at the peak tillering stage to ensure strong tillers, which is called strong tiller fertilizer. Tillering fertilizer is generally applied with high-nitrogen and high-potassium compound fertilizer, 8-15 kg per mu, as well as seedling fertilizer, and the height of cultivated soil is 10-12 cm. Sugarcane jointing fertilizer: jointing fertilizer is the key to increase sugarcane yield, which must be re-applied, and stem fertilizer is mainly applied nitrogen fertilizer. It is generally applied twice in the early and peak elongation stages, with 15-20 kg of high-nitrogen compound fertilizer per mu, combined with mid-tillage and soil cultivation, in order to promote sugarcane root growth, strengthen absorption function and enhance lodging resistance. If there is insufficient phosphorus and potassium in the early stage, it should be supplemented so that it can not only achieve the maximum growth, but also not reduce the sugar content and yield because of too much nitrogen fertilizer. Sugarcane tail fertilizer: in order to promote and maintain late growth, be conducive to the cultivation of underground sugarcane buds, and lay a good foundation for the perennial root of the following year, a strong tail fertilizer should be applied. Generally, 5-8 kg compound fertilizer is used per mu about two months before maturity. The application time should not be too late, and the dosage should not be too much, so as not to delay ripening and reduce sugar content, and cultivate the soil after application. If there is a phenomenon of de-fertilization one month before harvest, foliar fertilizer should be sprayed with 4 taels of potassium dihydrogen phosphate per mu, 0.5 kg of urea and 100 kg of water and then sprayed.
