Detailed Explanation of the Latest Sugarcane Harvesting Precautions
Sugarcane tastes sweet and is a fruit we love. In addition, it is rich in nutrients and has good planting prospects, making it a good project for making a fortune. During sugarcane harvest, only by adopting the correct methods can the sugarcane yield be increased and the ratoon sugarcane achieve high yield the following year, so there are three key points to note during harvesting. Let's take a look together below.
1. Harvest at the right time
The harvest of the previous sugarcane crop has an extremely large impact on ratoon sugarcane. If harvested too early, the period of low temperature and drought is too long, which is not conducive to the germination of sugarcane buds. They are easily affected by low temperature and thus lose vitality, and may also be affected by drought, leading to death, affecting the yield and quality of ratoon sugarcane. According to practical production experience, in southern regions, after Great Cold and during the Beginning of Spring is the most suitable period for retaining ratoons, so harvesting at this time is best. This is because the temperature has already begun to rise again at this time, and rainfall is also gradually increasing. Both temperature and moisture can meet the needs of sugarcane germination, promoting ratoon sugarcane to sprout stalks as soon as possible. In addition, harvesting must be carried out on sunny days. If harvesting is carried out in rainy weather, pathogens will invade through the wounds via rainwater, thereby damaging the ratoons and affecting stalk emergence.
2. Ensure sugarcane quality
At harvest, the quality of the planted sugarcane is an extremely important point during harvesting, because whether the sugarcane quality is good or bad also has an extremely large impact on ratoon growth. During harvesting, relatively sharp tools should be chosen, and when cutting, it must be done quickly so that the wound is smooth and will not crack. After cutting, use a small hoe to appropriately cut off some of the sugarcane stubble, keeping the length of the sugarcane stubble at 7-10cm. This is because if the retained sugarcane stubble is too long, it will affect the germination of young buds, causing the stalks to become thin and weak after sprouting. The cutting of sugarcane stubble is also not carried out immediately after harvest. Generally, harvest is done at the Beginning of Spring, and after the weather warms in spring, the stubble is cut away, so that ratoon sugarcane sprouts neatly.
3. Clean the field in time
After harvest, the field should be cleaned in time, and debris such as sugarcane leaves in the field should be removed completely. This is to avoid sugarcane leaves covering the sugarcane stubble, lest the stubble rot and turn sour, affecting sprouting. In addition, sugarcane leaves will also rot and decompose, breeding a large number of bacteria and microorganisms, harming the ratoons. Cleaning the field can either leave the sugarcane leaves in the field, pile them together to let them rot on their own, and then use them to make fertilizer returned to the field; collect and pile the sugarcane leaves in the furrow to be used directly as fertilizer; or dry and burn them, then use them as fertilizer. Sugarcane leaves can provide pollution-free organic fertilizer for the field, improve soil structure, and increase the yield of ratoon sugarcane.
