增施钾肥,香蕉植株对钾、磷的吸收增加,而对氮、钙、镁、铜的吸收减少。施用镁肥除对铜外,对其它元素的吸收无多大影响。增施钾时,香蕉根部减少;根对钾、镁、锰、铜的吸收率与外部介质的浓度成比例,其它元素的吸收则更多地受植株本身需要量的影响。大量施锰导致钙、镁、锌的吸收量减少,但对其它元素的影响甚微。香蕉根对
Increased potash, banana plant potassium, phosphorus absorption increased, while the reduction of nitrogen, calcium, magnesium, copper absorption. In addition to the use of magnesium fertilizer on the copper, the absorption of other elements have little effect. When applying potassium, the root of banana decreased. The absorption rate of potassium, magnesium, manganese and copper was proportional to the concentration of external medium. The absorption of other elements was more affected by the requirement of plant itself. A large number of manganese causes calcium, magnesium, zinc absorption decreased, but little effect on other elements. Banana root right
