Sugarcane has a long growth period and high yield. Generally, it can produce 5000-8000kg of cane stems per acre. It absorbs more nutrients throughout the growing season and is one of the crops requiring a relatively large amount of fertilizer. According to the research, for every 1,000 kilograms of sugar cane grown, 1.5-2 kilograms of nitrogen, 1-2.5 kilograms of phosphorus, 2-2.5 kilograms of potassium and 0.5-0.75 kilograms of calcium are needed to be drawn from the soil. Sugarcane is divided into seedling stage, tillering stage, elongation stage, and maturity stage. The requirements for fertilizers are different during different growth stages. The total fertilizer absorption pattern is roughly “two less, more intermediateâ€, that is, at the seedling stage, the fertilizer needs to be eagerly cut. With less absorption, the demand for nitrogen is slightly higher, followed by phosphorus and potassium. At the stage of tillering, the amount of fertilizer required gradually increases, and the absorption of three factors accounts for approximately 10%-20% of the whole period; The absorption of the three elements has increased significantly, accounting for more than 50% of the total period. At this time, high temperature, rainy and strong light seasons, the utilization of light energy and nutrients by sugarcane is the highest, which is the key fertilization period; after the mature period The amount of fertilizer needed by sugar cane gradually decreases. According to the nutritional requirements and characteristics of sugarcane, high-yield cultivation and fertilization should be based on the principle of “combination of nutrition and growth requirements, combination of organic and inorganic fertilizers, and combination of long- and slow-acting fertilizersâ€.
Fertilizer base fertilizer should be based on organic fertilizer, and with a certain amount of compound fertilizer, for the rapid growth of sugarcane sprouts, root elongation, early and strong childbirth to create good conditions. Generally, about 2000 kg of organic fertilizer is fully cooked per acre, and 20-30 kg of general-purpose (15%-15%-15%) compound fertilizer is applied. At the time of application, the spring planting cane first opens the planting ditch, then applies the organic fertilizer to the ditch, and then applies the compound fertilizer on both sides of the ditch. Winter planting can use organic fertilizer as cover fertilizer.
As early as the young seedlings of sugar-cane plantation, the amount of fertilizer required is small but the fertilizer is urgently needed. The early application of the young seedling fertilizer is beneficial to the length of the cane and the root, and can also promote the growth of the leaf and early growth of the childbirth. When the cane seedlings grow to 3-4 leaves, apply 8-10 kg of high-nitrogen compound fertilizer per acre, combined with direct acupoint application in cultivating soil (in case of drought, water should be applied to water points).
Stable application of fertilizers and fertilizers should be due to the use of seedlings, if the base fertilizer and the extraction of seedlings are sufficient, the seedlings are strong, and can be applied once in the flood season, and the amount of fertilizer should be less; if the base fertilizer is insufficient, the seedling fertilizer is not enough, the seedlings Weak growth, should increase the amount of fertilizer, and divided into two (once in the early stages of childbirth, to promote childbirth, known as attacking manure fertilizer. One application during the flooding period, to ensure strong growth, known as strong manure). The manure fertilizer is generally applied with high-nitrogen and high-potassium compound fertilizer, applying 8-15 kg per acre, and applying water points (in time after application).
Re-applying stem fertilizers to attack stem fertilizers is the key to sugar cane production. It is generally applied twice in the early stage of elongation and during the prolonged period of growth. Each stage uses 15-20 kg of high-nitrogen compound fertilizer per acre, combined with cultivator soil to promote Sugarcane roots grow, enhance absorption, and increase resistance to reversal. If the early phosphorus and potassium is insufficient, it should also make up the application of phosphorus and potassium fertilizer, so that it can not only achieve the maximum growth, but will not reduce the sugar content and yield due to excessive nitrogen fertilizer.
Supplementing the Shi Tsang Tail Fertilizer to promote and maintain the growth of the later period, conducive to raising the underground cane buds, to lay a good foundation for the following year, generally should be 2 months before maturing Tail fat. However, attention should be paid to the application time of the tailstock fertilizer should not be too late, the amount should not be too much, otherwise it will lead to delayed ripening, reduced sugar. In addition, if defertilization occurs 1 month before harvest, 1-2 times extra-root topdressing should be carried out. 0.2 kg of potassium dihydrogen phosphate per acre and 100 kg of urea 0.5 kg should be uniformly sprayed from top to bottom.
