What techniques can increase sugar content in sugarcane planting?
What techniques can increase sugar content in sugarcane planting? Please give instructions to increase the sugar content of sugarcane can be increased by fertilization, the method can refer to the following techniques: pay attention to sugarcane production, mainly to improve the yield and quality of sugarcane. First of all, the important measure to improve the sugar content of sugarcane is to match nutrition reasonably, which is reflected by a number of practical data. The proportion of nitrogen, phosphorus and potassium needed for sugarcane is about 4:1:2. In order to ensure that sugarcane has enough nutrition in the whole growing period and can provide nutrients to the plant continuously, attention should be paid to the application of organic fertilizer in base fertilizer, which is about 2000 kg per mu. In order to reduce the effect of phosphate fertilizer easily fixed by soil, about 30 kg of calcium superphosphate should be mixed with organic fertilizer for ripening. Because potassium fertilizer is mostly absorbed by soil colloid and becomes substituted potassium, it has less mobility in the soil and is generally not easy to lose, so it should be applied near the rhizosphere. It is also because the law of potassium absorption by sugarcane is mainly concentrated in the early and middle stages, accounting for about 80% of the total potassium absorbed in the whole period. Moreover, the potassium absorbed in the early stage can be transferred to the later growth in the plant, so the potassium fertilizer should also be applied early, accounting for 50% of the total base fertilizer, and the remaining 50% should be applied at the peak tillering stage or early elongation stage. Generally, 13.5 kg of potassium chloride or 15 kg of potassium sulfate and about 35 kg of urea are applied throughout the growing period. In addition to applying basal fertilizer, the remaining fertilizer combined with manure and water should be topdressing at tillering stage (7m / m 8 leaves), elongation stage and peak elongation stage respectively. The proportion of fertilizer application in the peak elongation period is relatively large, accounting for about 50% of the remaining fertilizer. During the whole growing period, sugarcane should supplement trace elements through foliage many times. It is suggested that amino acids easily absorbed by plants and foliar fertilizers containing elements such as zinc, boron and magnesium should be sprayed, as well as potassium dihydrogen phosphate and Tianfengsu. If sugarcane is planted in winter or early spring, plastic film mulching can be used to increase the temperature inside the film and the surface, increase the biological activity of enzymes in the species, accelerate the germination of sugarcane buds, improve the survival rate and strengthen seedlings. It can make the plant grow early and quickly, prolong the effective growth period, increase the accumulation of light energy products, and increase sugar content and yield. In short, to improve the sugar content of sugarcane, it mainly needs a reasonable collocation of fertilizer elements in the rhizosphere; through the foliar supplement of trace elements for many times; and the adoption of advanced plastic film mulching cultivation techniques to prolong the effective growth period and increase sugar transformation.

How to apply fertilizer effectively in sugarcane planting
How to apply fertilizer effectively in sugarcane planting? Please introduce that due to the well-developed root system and long growth period of sugarcane, a large amount of nutrients should be taken away from the soil in each crop. Therefore, planting sugarcane and applying organic fertilizer can improve soil structure, and it is very effective to increase yield and improve soil. Base fertilizer: apply sufficient base fertilizer.

How to fertilize sugarcane for high yield? Please introduce the long growing period and high yield of sugarcane. Generally, it can produce 5000kg to 8000kg of sugarcane per mu. It absorbs a lot of nutrients during the whole growth period and is one of the crops that need a large amount of fertilizer. According to research, for every 1000 kg of sugarcane, it is necessary to absorb 1.5 kg of nitrogen and 1 kg of phosphorus from the soil.
