چکیده

روش تشخیص چندگانه عناصر غذایی (CND) از روش­های مهم برای تفسیر نتایج تجزیه شیمیایی برگ و تشخیص وضعیت تغذیه­ای گیاهان می­باشد. به ­منظور ارزیابی وضعیت تغذیه­ای کدو (Lagenaria Vulgaris) با استفاده از روش CND و تعیین نرم­های عناصر غذایی، نمونه­های برگ از 122 مزرعه کدو در شهرستان خوی جمع­آوری و غلظت­های عناصر غذاییB ،Cu ،Zn ،Mn ،Fe ،Mg ،Ca ،K ،P  ،N تعیین شدند. دو گروه عملکردی کم و زیاد به روش ریاضی و آماری و با کاربرد تابع تجمعی نسبت واریانس عناصر غذایی متمایز گردیدند. سپس نرم­ها و شاخص­های CND برای عناصر غذایی محاسبه گردید. نتایج نشان داد بین مزارع با عملکرد بالا و پایین از لحاظ غلظت عناصر غذایی تفاوت معنا­دار وجود دارد. براساس شاخص­های CND عناصر پتاسیم و روی منفی­ترین شاخص­ها را داشتند. شاخص­های تعادل تغذیه­ای CND در مزارع با عملکرد پایین بزرگتر از صفر به­دست آمد که نشان­دهنده عدم تعادل عناصر غذایی در این مزارع می‌باشد.

چکیده [English]

Compositional Nutrient Diagnosis (CND) methods are important to interpret the results of chemical analysis and diagnosis of nutritional status of plants. In order to evaluate the nutritional status of squash (Lagenaria Vulgaris) through CND and to determine nutrient norms for this crop, 122 leaf samples were collected from squash fields of Khoy region and N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B elements in the samples were analyzed. The squash fields were divided into two high and low yielding groups, based on mathematical and statistical methods and by additive function of variance ratio and then the CND indices and norms were calculated. Results of the research showed that there were significant differences between high and low yielding fields in terms of nutrients’ concentration. Based on CND indices, potassium and zinc nutrients had the most negative indices. CND nutritional balance index of low yielding fields were more than zero indicating nutritional imbalances in these fields.
