What should black sugarcane continuous cropping pay attention to?

What should be paid attention to in black sugarcane continuous cropping? One of the main reasons for the poor yield and poor quality of black sugarcane continuous cropping is the lack of medium trace elements such as magnesium, silicon, calcium, zinc, boron, iron, molybdenum and manganese in the soil, resulting in insufficient supply of medium trace elements, resulting in poor growth of sugarcane, not only short plants, thin internodes, but also low sugar content and tasteless sugarcane juice. Because of the strong ability of absorbing medium trace elements, sugarcane has basically absorbed all the medium trace elements in the soil in the first year of planting, and continuous cropping will lack medium trace elements. Therefore, continuous cropping of sugarcane should pay attention to the application of medium trace element fertilizer in order to achieve high yield and high quality. The specific methods are as follows: in the seedling stage, early and middle stages of jointing and elongation of black-skinned sugarcane, medium trace element fertilizers were applied once, for example, a large number of element water-soluble fertilizers were applied in the market, 3-5kg per mu and 150kg / mu mixed with clean water. evenly sprinkle it in the soil around the root of the sugarcane seedling in the planting hole. At the same time, during the young fruit stage and jointing and elongation period of sugarcane, 1000 times of medium amount of trace element water-soluble fertilizer solution was sprayed on the leaf every 10-15 days, and continuously sprayed for 3-5 times to wet all the leaves evenly.
