【摘要】 通过盆栽试验,研究泥炭、沸石、稀土及保水剂四种化学材料及其复合应用对玉米幼苗生长、生理特性的影响。研究表明,在水分胁迫下提高WUE宜采用保水剂+泥炭处理;在半干旱地区为提高WUE和获得较高生物量直采用沸石+稀土+保水剂;在阴湿地区为充分利用光能宜采用保水剂+沸石;在水分充足地区为促进光合、提高肥料利用率宜采用保水剂+沸石。更多还原

【Abstract】 By pot experiment method, it is studied the effects of aquasorb ,rare earth element ,zeolite and turf these four chemic materials, by using single and their complex, on physiological characteristics and growth of maize seeding. Based on the experimental results, it is indicated that in drought area of water stress, should adopt the disposal of aquasorb add turf to improve the water use efficiency(WUE); In semiarid area should adopt the disposal of aquasorb add rare earth element add zeolite to improve the WUE and high gain and bio-mass; In shortage of light and low temperature area, it adopt aquasorb add zeolite to promote the light use efficiency; In water enough area, it should adopt aquasorb add zeolite to promote photosynthesis and raise fertilizer use efficiency.更多还原
