چکیده

با توسعه جوامع بشری، ایجاد امنیت غذایی در اولویت قرار گرفته است. هر چند جامعه بشری با پیشرفت تکنولوژی و معرفی کودهای شیمیایی و سموم دفع آفات نباتی توانسته باعث افزایش چشمگیر تولید غذا گردد ولی هنوز هم کیفیت غذا جزو مسائل پر اهمیت محسوب می‌شود. یک راهکار مناسب، کاربرد کودهای با منشأ آلی است. از سالیان طولانی، کشاورزان مناطق ساحلی، جلبک‌های دریایی را برای افزایش رشد گیاهان در مزارع خود استفاده می‌کردند. امروزه با پیشرفت تکنولوژی، برخی از گونه‌های جلبک‌های دریایی، تولید و فراوری شده‌اند و به‌صورت جداگانه یا مخلوط با سایر ترکیبات کودی، مورد استفاده تولیدکنندگان بخش کشاورزی قرار می‌گیرند. هرچند کود عصاره جلبک دریایی، عناصر غذایی ناچیزی دارد ولی به دلیل دارا بودن مقادیر بالایی از مواد تنظیم‌کننده رشد گیاهی به‌صورت طبیعی، به عنوان محرک رشد در بهبود و تسریع رشد و رفع عوارض حاصل از تنش‌های محیطی در گیاهان، کاربردهای فراوانی یافته است.

چکیده [English]

Due to the development of human societies, food security has become a priority. Technological advancements and introduction of chemical fertilizers and pesticides have provided sufficient quantities of food in recent decades, but food quality is questioned. Fertilizers from natural sources might be a practical solution. Coastal farmers in various countries have been applying seaweed for crop growth and development for many years. Nowadays, with technological development, some species of seaweed such as Ascophyllum nodosum are cultivated and processed as seaweed extract alone or mixed with other fertilizers to be used by farmers. Although seaweed extract contains small amounts of mineral nutrients, it has been applied widely as a growth stimulator for improving and accelerating crop growth and development and eliminating environmental stresses.
