摘要
经过大田与盆栽试验,研究了ABT生根粉对玉米产量及抗旱性的影响。结果表明:ABT生根粉在旱作及结构粘重的灌溉玉米田上使用有显著的增产效果。其增产原因主要是促进了根系的生长,使玉米吸收水肥的能力增强,提高了抗旱性,而在土壤结构良好,供水充足的灌溉玉米田增产作用则较小。
he effects of root-stimulating agent ABT on maize yields and
droughtresistance was studied through field and pot experiments.The results indicated
thatroot-stimulating agent ABT can increase maize yield significantly in rainfed field or
ir-rigated field with heaily-textured soil.The main reason for yield increase is due to
theimprovement of high drought resistance caused by ABT’s stimulating development ofroot
system so as to strengthen maize ability to absorb water and fertilizer.But thisyield increase is
little in irrigated field with plenty of water supplles or in the farmlandwith good-textured soil.
