摘要
通过玉米盆栽试验,研究了在水分胁迫条件下,泥炭、沸石、稀土、保水剂等不同特性化学材料对玉米幼苗生长及生理的影响。结果表明,这些化学材料能够部分补偿水分胁迫给玉米带来的伤害,提高玉米幼苗的抗旱性能,并且各类化学材料的作用效果是不同的。
The effects of four chemical materials, including peat, zeolite, rare earth elements, and aquasorb, on physiological characteristics and growth of maize seedlings were studied with pot experiment under water stress. Based on the experimental results, it was indicated that the damage caused by water stress was partly compensated by using these materials, and the drought resistance of maize was increased. The effect of different chemical materials on maize seedlings was different.
