摘要
钾、镁水培试验结果表明,施用适量钾和镁均可显著增加甘蔗生物产量,但其增加量受到钾、镁供应水平的影响。其增产原因在于,施用适量钾、镁肥影响了蔗株体内养分平衡,提高了叶片中叶绿素含量,从而增加了株高和茎径,提高了生物产量。
The main results of water-culture experiment were shown that optimum potassium and magnesium supply increased the dry matter of sugarcane significantly,but it was controlled by potassium or magnesium supply.The reason is that optimum potassium and magnesium supply affected the nutrient balance in plants and increased the chlorophyll content in leaves.Therefore the plant height and stem diameter as well as the dry matter of sugarcane will be increased.
