How to manage sugarcane during the jointing stage? Keep these key points in mind
Sugarcane is a rather unique fruit crop with very large demand in our country, and it is grown on a large area across the country. It contains very abundant sucrose. Growing sugarcane is neither difficult nor simple, and each growth stage of sugarcane has different management methods. For example, the jointing stage of sugarcane is the most important period of sugarcane growth, so how should it be managed during the jointing stage? Let's take a look together below!
1. Prevent lodging
The jointing stage of sugarcane is the stage of rapid growth and an important period in the sugarcane growing process. At this time we should fertilize appropriately and combine this with earthing up. This can not only improve soil fertility, but also promote root growth and development, and prevent lodging when the sugarcane grows too tall. For earthing up, the high earthing method should be chosen, surrounding the sugarcane stalk segment by segment with soil, but note that it should be covered segment by segment so that each segment of the sugarcane can absorb enough nutrients and promote its growth. When earthing up, apply an appropriate amount of topdressing, pay attention to the harm caused by poultry, and strengthen field management.
2. Irrigate to prevent drought
The jointing stage is generally around August each year. The temperature at this time is relatively high, so attention should be paid to irrigation to provide enough water for sugarcane. Only then can the elongation and development of sugarcane be improved. If continuous drought occurs, replenish water in time to keep the soil moist. Do a good job of water conservation in the field, take measures for shading and sun protection, prevent the temperature in the orchard from dropping, and reduce the rate of water evaporation in the orchard. Growers with the conditions can lay irrigation systems in the orchard and carry out pumped irrigation. In short, ensure the growth of sugarcane and increase the yield.
3. Fertilization management
The jointing stage of sugarcane is the most important time in the entire growth stage, because at this time the leaves and stems of sugarcane grow rapidly and this is when fertilizer is needed most. The fertilizer requirement at this stage accounts for half of the total fertilizer amount, so at this stage we should focus on fertilization, mainly nitrogen fertilizer, to promote the growth and development of the stems, increase the sugar content in the plant, and raise the yield. However, it must not be applied alone in excessive amounts; phosphorus and potassium fertilizer should also be supplemented appropriately, and topdressing should be applied properly according to soil fertility and sugarcane growth. If excessive, it will cause excessive vegetative growth of sugarcane, and applying a single fertilizer will make the nutrition of sugarcane unbalanced and affect quality.
4. Enhance ventilation
Strong permeability is one of the important factors for ensuring good growth and development of sugarcane. The growth rate of sugarcane in the later stage is extremely fast, basically producing a new leaf every week. Therefore, in order to enhance the permeability in the orchard, some leaves should be removed appropriately, and old leaves and leaves that have already turned yellow and withered should be picked off. This is also beneficial to the photosynthesis of sugarcane, making the sugarcane stalks more robust, further enhancing lodging resistance, and the accumulation of sugar will also gradually increase. Therefore, when planting, everyone should appropriately prune excess sugarcane leaves, which can also reduce the probability of disease occurrence.
The above are the key management points for sugarcane during the jointing stage. Sugarcane is favored by many people. However, growing it is not easy. Sugarcane cultivation requires growers to have a certain level of skill, after all, management methods change with growth. Everyone should also pay more attention to the occurrence of pests and diseases, and only by observing more can problems be discovered and response measures taken in time.
