What should be noted when planting black-skinned sugarcane in continuous cropping?
What should be noted for continuous cropping of black-skinned sugarcane? Please give guidance. One of the main reasons for the low yield and poor quality of black-skinned fruit sugarcane under continuous cropping is that the soil lacks medium and trace elements such as magnesium, silicon, calcium, zinc, boron, iron, molybdenum and manganese, resulting in an insufficient supply of medium and trace elements, which causes poor growth of the fruit sugarcane, not only...
What should be noted for continuous cropping of black-skinned sugarcane? Please give guidanceOne of the main reasons for the low yield and poor quality of black-skinned fruit sugarcane under continuous cropping is that the soil lacks medium and trace elements such as magnesium, silicon, calcium, zinc, boron, iron, molybdenum and manganese, resulting in an insufficient supply of medium and trace elements, which causes poor growth of the fruit sugarcane, not only short plants and thin, weak internodes, but also low sugar content and bland, tasteless cane juice. Because fruit sugarcane has a strong ability to absorb medium and trace elements, in the first year of planting it has basically absorbed all the medium and trace elements in the soil, so continuous cropping will lead to a lack of medium and trace elements. Therefore, when continuously cropping fruit sugarcane, attention should be paid to applying additional medium and trace element fertilizers so that the fruit sugarcane can be high-yielding and high-quality. The specific methods are as follows:
At the seedling stage, the early stage of jointing and elongation, and the middle stage of black-skinned fruit sugarcane, apply a medium and trace element fertilizer once each time, such as the various macro-element water-soluble fertilizers currently on the market, applying 3~5 kg per mu each time, diluting with clean water at 150~200 times, and evenly pouring it onto the soil around the roots of the fruit sugarcane seedlings in the planting holes. At the same time, during the young fruit stage and the jointing and elongation period of the fruit sugarcane, spray a 1000-times water solution of medium and trace element water-soluble fertilizer on the leaves once every 10~15 days, spraying continuously 3~5 times, evenly wetting all the leaves, until water droplets begin to drip down.
