Plant performance in soil as a heterogeneous system

在目前的研究中，植物在土壤中的表现作为一个非均质系统进行了研究，并考虑了它们在缓解土壤应力方面的应用。研究表明，土壤中固定不动的磷酸盐的局部供应比均匀供应更有利于植物的生长。当根系遇到空间上不均匀的土壤水分时，水分可能会从根部排入干燥的土壤。通过使用该工艺，一些根系具有降低咸水含盐量的潜力。结果表明，土壤压实可以缓解铝毒，铝毒害是酸性土壤胁迫的主要因素。

In the current studies, plant performances just occurring in soil as a heterogeneous system were investigated and considered their applications to alleviate soil stress. Localized supply rather than uniformly supply of phosphate, which is immobile in soil, was shown to be effective for plant growth. When a root system encounters spatially heterogeneous soil moisture, water efflux can occur from the root into dry soil. By using the process, some root system had a potential to reduce salinity level of saline water. It was found that Al toxicity, which is a major factor of acid soil stress, could be alleviated by soil compaction.
