چکیده

به منظور بررسی اثر شوری آب آبیاری با سیستم آبیاری قطره­ای نواری بر خصوصیات شیمیایی خاک آزمایشی با چهار تیمار شوری آب آبیاری 2، 6، 9 و 12 دسی­زیمنس برمتر در قالب طرح بلوک­ کامل تصادفی با سه تکرار برای هر تیمار در یک مزرعه ذرت انجام شد. آزمایش در یک منطقه خشک با بافت لومی و شوری خاک بالا انجام شد. نتایج حاصل از تجزیه شیمیایی برای عمق­های 30- 0، 60- 30 و 90- 60 سانتی­متری خاک نشان داد که در هر لایه از خاک با افزایش شوری آب آبیاری شوری عصاره اشباع خاک افزایش می­یابد و میزان شوری عصاره اشباع خاک در لایه­های زیرین نسبت به لایه­های بالایی بیشتر است. در طول فصل رشد گیاه در هر سه لایه پروفیل خاک با اعمال آبیاری یکنواخت با شوری 1 دسی­زیمنس برمتر شوری عصاره اشباع خاک، نسبت جذبی سدیم، بیکربنات، کلر و درصد سدیم قابل تبادل خاک کاهش یافت و با اعمال تیمارهای شوری آب آبیاری بعد از مرحله چهار برگی گیاه ذرت مقدار این پارامترها در طول فصل رشد گیاه افزایش یافت. در مناطق با کمبود آب شیرین، آبیاری با آب شور تحت سیستم آبیاری قطره­ای موجب یکنواختی توزیع آب در خاک و همچنین توزیع مناسب شوری خاک می­شود.

چکیده [English]

To study the effect of irrigation water salinity on soil chemical characteristics, a randomized complete block design experiment was conducted with four treatments of irrigation water salinities of 2, 6, 9 and 12 dS/m with three replications for each treatment in a corn field under drip irrigation system (T-Tape). The study was carried out in an arid region with high initial soil salinity and soil texture of loam. Results of soil chemical analysis from different soil depths of 0-30, 30-60 and 60-90 cm showed that in each layer of soil with increase in irrigation water salinity the salinity of soil saturated extract increases and the salinity of soil saturated extract in deeper layers was higher than upper layers. During the growing season, for each of three soil layer profiles, with uniform irrigation with water salinity of 1dS/m the value of the ECe, SAR, HCO3, Cl and ESP were decreased. However, irrigating with different irrigation water salinities caused that the above values increase after the crop stage of four leaf corn and the maximum increase occurred at the end of growing season. In regions with lack of fresh water, irrigating with saline water under drip irrigation will result in uniform distribution of water and soil salinity in soil profile
