灌区农业中土壤碱化是一个持续性问题,土壤中如Cl~-浓度相当高,可能出现植物毒害现象。能与Cl~-产生颉抗作用,或能对植株体内能量的变化产生有利影响的肥料离子,将是有用的,它可降低Cl~-的毒性。磷、氯都是植物的必需元素,但与磷相比,低量的Cl~-就可出现毒害作用。在碱性土中,过量地施用磷,也会引起磷中毒,Abrol指出,磷抑制植株对Cl~-的吸收比Cl~-抑制植株对磷的吸收更加明显。根据这一观点,本试验研究了
Soil alkalization in irrigated area agriculture is a persistent problem. The concentration of Cl ~ - in soils is quite high, and plant poisoning may occur. It would be useful to be able to antagonize Cl ~ - or fertilizer ions that have a beneficial effect on changes in plant body energy, which would reduce Cl ~ - toxicity. Phosphorus, chlorine are essential elements of plants, but compared with phosphorus, low levels of Cl ~ - toxic effects can occur. Excessive application of phosphorus in alkaline soils can also cause phosphorus poisoning, and Abrol states that phosphorus uptake of Cl by plants is more pronounced than that of Cl ~ - inhibition by plants. According to this view, the experimental study
