Abstract :

گلایل یکی از گل‌های محبوب در دنیاست که عدم تعادل تغذیه، تولید آن را کاهش داده و همچنین تلفیق غیر اصولی کودها نیز مشکل‌ساز شده است. مطالعه‌ی اخیر برای تعیین اثرات مصرف توأم N، P و K روی رشد، نمو گل و جذب N، P و K در گلایل انجام شده است. N، P و K به‌صورت NPK (10:20:10 گرم در مترمربع)، N (20 گرم در متر مربع)، P (10 گرم در متر مربع)، K (10 گرم در متر مربع)، N+P (10:20 گرم در متر مربع)، N+K (10:20 گرم در متر مربع) و P+K(10:10 گرم در مترمربع) استفاده شدند. در بین تیمارها، رشد بهتر از نظر درصد جوانه‌زنی بیشتر، ارتفاع گیاه و سطح برگ در تیمار NPK حاصل شد. حال آن‌که طول ساقه و طول گل‌آذین در تیمار P+K به‌صورت معنی‌داری بیشتر بود. همچنین مشاهده شد که NPK باعث وزن تر و خشک گلچه‌ی بالاتر شد، در حالی‌که P در افزایش وزن پداژه اهمیت بیشتری دارد. کلروفیل برگ بالاتر و جذب N بیشتر در تیمار NPK صورت گرفت. در تیمار P حداکثر جذب P به چشم خورد و در تیمار P+K بالاترین جذب Kمشاهده شد. نتایج ما نشان داد که تغذیه متعادل (NPK) برای تولید پایدار گلایل بهتر است.
