植物耐低磷胁迫研究进展

Overview on Research Progress of Plants in Low Phosphorus Stress

磷素利用率低已成为现代农林业产量的限制因子,传统农业都是通过多施磷肥来解决植物对磷素的需求,但累积在土壤中的磷不仅造成了土壤中磷素富集,还增加了对水体污染的风险,筛选耐低磷基因型品种成为替代传统方法提高磷素利用率,防治环境污染的首选方法。本文综述了植物低磷胁迫下的生理生态学变化,并对当前的研究成果提出了需要进一步深入研究的方向。

The low utilization rate of phosphorus has become a critical restriction factor on improving yield at farming and forests. The usual response of applying increased amount of phosphorus fertilizer led to excessive accumulation of phosphorus in soil and increased the risk of water pollution. A worthy alternative way to address this problem is to select genetically adapted crop varieties which can use phosphorus effectively. This approach also makes environmental sense. This paper introduced the physiological and ecological change of plants in low phosphorus stress and suggested future research direction in this field.
