【摘要】 在甘肃省石羊河流域开展了制种玉米咸水灌溉田间试验,研究咸水灌溉对制种玉米生长和土壤盐分分布的影响。研究结果表明:咸水灌溉对制种玉米的生长有一定的抑制作用,并且灌溉水矿化度越高,这种现象表现得越明显;咸水灌溉会使盐分在土壤各层中累积,并且灌水矿化度越高,盐分累积量越大;高矿化度的咸水进行长时期灌溉,则会使土壤产生盐碱化,影响作物的生长,但3g/l的微咸水进行长时期灌溉,对土壤盐分分布和作物生长的影响,还需要进一步的研究。更多还原

【Abstract】 A field experiment was conducted to study the effects of saline water irrigation on seed growth and soil salt distribution in Shiyang River Basin of Gansu province. The research results showed that saline water irrigation has inhibition effect to seed growth. It is noticed that the greater salinity of irrigation water, the more obvious of this phenomenon; Saline water irrigation can make salt accumulated in soil and the greater salinity of irrigation water, the more salt accumulation amount. High salinity of saline water will make soil salinization for a long period irrigation and it affect the growth of crops. But the 3g/l of slight saline water was irrigated for long periods of time, it must further studies in effects on soil salt distribution and seed growth.更多还原
