What are the latest management key points during the sugarcane jointing stage?
Sugarcane is a rather unique fruit crop, with very high demand in our country, and it is grown over large areas all across the country. It contains very abundant sucrose, and growing sugarcane is neither easy nor simple, as each growth stage of sugarcane has different management methods. For example, the sugarcane jointing stage 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. Preventing 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 the fertility of the soil, but also promote the growth and development of the roots, preventing lodging when the sugarcane grows too tall. For earthing up, the high earthing method should be chosen, surrounding the sugarcane joint by joint with soil, though be careful to cover it joint by joint so that every joint of the sugarcane can absorb enough nutrients and promote its growth. When earthing up, apply additional fertilizer in the right amount, pay attention to the harm caused by poultry, and strengthen field management.
2. Irrigation and drought prevention
The jointing stage is generally around August each year, and the temperature at this time is relatively high, so attention must be paid to irrigation to provide sugarcane with enough water. 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 shading and sun-blocking measures, prevent the temperature between the rows from dropping, and reduce the rate of water evaporation in the field. Growers with the means can install an irrigation system in the field and carry out pumped irrigation; in short, ensure the growth of sugarcane and increase the yield.
3. Fertilization management
The sugarcane jointing stage is the most important time of the entire growth stage, because at this time the leaves and stems of the sugarcane grow rapidly, and it 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 fertilizing, mainly with 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 or in excess; phosphorus and potassium fertilizer should also be supplemented appropriately, and additional fertilizer should be applied according to soil fertility and the growth of the sugarcane. Excess will cause excessive vegetative growth of sugarcane, and applying a single fertilizer will make the nutrition of sugarcane uneven and affect quality.
4. Enhancing ventilation
Strong permeability is one of the important factors ensuring good growth and development of sugarcane. In the later stage, sugarcane grows extremely fast, basically producing a new leaf every week. So in order to enhance the permeability in the field, some leaves should be removed appropriately, taking off old leaves and leaves that have already turned yellow and withered. This is also beneficial to the photosynthesis of sugarcane, making the sugarcane stalks more robust, further strengthening lodging resistance, and the accumulation of sugar will also gradually increase. So when planting, everyone should properly prune the excess leaves of sugarcane, which can also reduce the chance of disease occurrence.
The above are the management key points during the sugarcane jointing stage. Sugarcane is favored by many people. But growing it is not easy, and 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 observe more to detect them and respond in time. That is all for today's introduction, please keep following us.
