چکیده

استفاده بی­رویه از آفت کش­ها و کودهای شیمیایی باعث مشکلات زیست محیطی شده است. استفاده از کودهای آلی و زیستی در برنامه­های مدیریتی می­توانند موجب کاهش مصرف مواد شیمیایی شوند. پژوهش حاضر با هدف بررسی تأثیر سطوح مختلف ورمی­کمپوست (صفر، 5، 10، 15 و 20 گرم در دو کیلوگرم خاک)، نانوکود بیولوژیک (صفر، 1، 2 و 3 گرم در دو کیلوگرم خاک)، بیوچار (صفر، 25/1، 5/2، 5 و 10 گرم در دو کیلوگرم خاک) و همچنین ترکیب کودهای ورمی­کمپوست- نانوکودزیستی (10 گرم ورمی­کمپوست-2 گرم نانوکود زیستی در دو کیلوگرم خاک) و ورمی­کمپوست-بیوچار (10 گرم ورمی­کمپوست-5/2 گرم بیوچار و 10 گرم ورمی­کمپوست-5 گرم بیوچار در دو کیلوگرم خاک)، روی برخی ویژگی­های مورفولوژیکی و میزان ترکیبات فنلی عصاره گیاه دارویی سرخارگل (Echinacea purpurea L.) انجام گرفت. نتایج نشان داد که گیاهان کشت شده در تیمار ترکیبی ورمی‏کمپوست-بیوچار در مقایسه با سایر تیمارهای کودی، دارای بالاترین مقادیر طول ریشه (97/29 سانتی­متر)، وزن خشک شاخساره (54/10 گرم) و سطح برگ (40/147 میلی­متر مربع) بودند. همچنین کاربرد ترکیب ورمی­کمپوست- نانوکود زیستی نسبت به سایر تیمارها، وزن­تر ریشه (84/34 گرم) و وزن خشک ریشه (54/6 گرم) بیشتری را نشان داد. بیشترین میزان وزن­تر شاخساره در مقایسه با تیمارهای کودی دیگر در تیمار 5 گرم بیوچار به میزان 37/35 گرم به ازای هر گلدان مشاهده گردید. همچنین کشت گیاه دارویی سرخارگل تحت تیمار ترکیبی ورمی­کمپوست - بیوچار بر میزان ترکیبات فنلی عصاره گیاه مذکور تأثیر بهتری داشت که مقدار 123/0 میلی­گرم بر لیتر بود.

چکیده [English]

The excessive use of pesticides and chemical fertilizers causes environmental problems. Organic and biological fertilizers in management programs can be considered as a way to reduce utilization of chemical materials. The aim of this study was to investigate the effect of different levels of Vermi-Compost (0, 5, 10, 15 and 20 gr/pot), Nano biological Fertilizer (0, 1, 2, and 3 gr/pot), and Biochar (0, 1.25, 2.5, 5 and 10 gr/pot) as well as a combination of VermiCompost-Nano-compost (10 gr vermicompost-2 gr Nano-biologic fertilizer) and vermicompost-biochar (10 gr vermicompost-2.5 gr of Biochar and 10 gr vermiCompost and 5 gr of Biochar) was conducted on some morphological traits and the amount of phenolic compounds of Echinacea purpurea L. The results showed that plants grown in VermiCompost-Biochar combination treatment had the highest amount of root length factors (29.97 cm), dry shoot weight (10.54 gr/2 kg pot) and leaf area (14745.07 mm) compared to other fertilizer treatments. In addition, the use of vermicompost-compost-nano-bio fertilizer for other treatments caused the highest fresh root weight (34.84 gr) and root dry weight (6.54 gr). The highest fresh stem weight was observed in Biochar 5 gr treatment at 35.37 gr/2 kg pot compared to other fertilizer treatments. In addition, the cultivation of Echinacea under the combined treatment of Vermicompost and Biochar had the highest amount of phenolic compounds (0.123 mg /l).
