| 摘 要： | 通过盆栽实验对玉米幼苗生长及生理特性的监测,探讨了水分胁迫和正常供水条件下保水剂分别与泥炭、沸石和稀土复合应用的互作效应。结果表明,保水剂 泥炭在两种水分条件下均能复合应用,可有效促进玉米生长和提高水分利用效率;保水剂 沸石在正常供水条件下可进行复合应用,在水分胁迫时不适合复合应用;保水剂 稀土在两种水分条件下均不适合复合应用。

| Abstract: | The effects of aquasorb combined with peat,zeolite and rare earth elements respectively on physiological characteristics of maize seedlings under water stress and well-watered conditions were studied with a pot-grown experiment.The results show that the application of aquasorb and peat compound is favorable for maize growth under both water stress and well-watered conditions;the application of aquasorb and zeolite compound is practicable under well-watered conditions,but unsuitable under water stress;however,the application of aquasorb and rare earth elements compound is unfeasible under both water stress and well-watered conditions. |

| Keywords: | aquasorb peat zeolite rare earth elements water use efficiency maize |
