磷在自然状态下最常用于栽培烤烟的土壤中,有效磷是低的,因而可看到较高的施磷肥会促使植株早期的生长和增加最终的产量.由之在产烟区施用多量的磷肥已形成习惯.在长期栽烟的地区,重复施入超过植株能予吸收的大量磷肥,并且实际上未因淋溶而流失,
Phosphorus, which is most commonly used in flue-cured tobacco soils in the natural state, is low in available phosphorus so that higher phosphorus fertilizers are expected to promote early plant growth and increase final yield, Phosphate fertilizer has become a habit.In the long-term tobacco planting areas, repeated application of more than plants can absorb a large number of phosphate fertilizer, and in fact did not drain due to leaching,
