| چکیده | ||
| در این تحقیق تأثیر زیرشکنی خاک و فواصل گوناگون از محور زهکشی روباز در قالب طرح آماری کرت‌های نواری و در سه تکرار بر جرم مخصوص ظاهری، شاخص مخروط خاک، سرعت نفوذ آب به خاک، شوری عصارۀاشباع خاک و عملکرد گندم بررسی شد. تیمار اصلی فاصله از محور زهکشی شامل سه فاصلۀ50-0، 100-50، و 150-100 متری و تیمار فرعی عملیات خاک‌ورزی شامل سه روش فقط استفاده از گاوآهن برگردان‌دار و بدون زیرشکنی خاک، زیرشکنی خاک به عمق 45-40 سانتیمتر، و زیرشکنی خاک به عمق 45-40 سانتیمتر+گاوآهن برگردان‌دار انتخاب شدند. نتایج نشان داد که زیرشکنی خاک باعث کاهش پارامترهایی مانند شاخص مخروط خاک به میزان 25درصد، جرم مخصوص ظاهری خاک به میزان 4درصد، شوری عصارۀاشباع خاک به میزان 25درصد، و افزایش پارامترهایی مانند سرعت نفوذ آب به خاک به میزان 133درصد، و عملکرد گندم به میزان 18درصد شد. | ||

| چکیده [English] | ||
| The split-block experimental design with three replications was used to study the effect of subsoiling in different distances from drain axison soil salinity,and wheat yield. The measurements included soil cone index, soil bulkdensity, infiltration rate and electrical conductivity of saturated extract. Each treatment was composed of two factors. The main factors consisted of 3 different distances from drain axis including 50, 100 and 150 meters from drain axis; and the sub factors consisted of 3 cultivation methods as conventional plowing, subsoiling at soil depth of 40-45cm, and subsoiling at the soil depth of 40-45 cm + plowing. The results included that subsoiling decreased the value of soil cone index (about 25%), soil bulk density (about 4%), EC- saturated extract (about 25%), and the magnitude of other parameters such as infiltration rate and wheat yield increased by 133% and 18%, respectively. | ||
