چکیده

نیتروژن نقش مهمی در مدیریت تغذیه درخت در مرکبات ایفا می‌کند. آزمایشی به­منظور بررسی اثر سطوح مختلف اوره (صفر، 75/0%، 5/1%)، و زمان‌های مختلف محلول‌پاشی اوره (اول دی‌ماه، 15 دی‌ماه، 30 دی‌ماه)، به­صورت فاکتوریل در قالب طرح بلوک‌های کامل تصادفی با سه تکرار بر میزان نیتروژن، فسفر، پتاسیم، برگ و گره و خصوصیات گل و عملکرد گیاه نارنگی رقم کینو، صورت گرفت. در این آزمایش از برگ و گره در 1، 3 و 5 هفته بعد از محلول‌پاشی نمونه‌برداری انجام شد. نتایج این پژوهش نشان داد که سه هفته بعد از محلول‌پاشی 1 دی، بیشترین مقدار نیتروژن برگ (5/2%) مربوط به گیاهان محلول‌پاشی­شده با غلظت 5/1% اوره بود درحالی­که بیشترین مقدار نیتروژن گره (73/1%) در گیاهان تیمار­شده در 30 دی‌ماه با غلظت 5/1% اوره به­دست آمد. بیشترین مقدار پتاسیم و فسفر برگ گیاهان محلول­پاشی در 30 دی‌ماه با غلظت 5/1% اوره گزارش شد. همچنین غلظت‌های مختلف اوره موجب افزایش تعداد گل، تحریک رشد تخمدان و افزایش عملکرد شد و بیشترین تأثیر مربوط به بالاترین غلظت اوره (5/1%) گزارش شد.

چکیده [English]

Nitrogen plays an important role in managing the nutrition of the citrus. An experiment was set  as  factorial in a randomized complete block design with three replications to investigate the effect of different levels of urea (0, 0.75%, 1.5%), and different times of urea foliar application (Dec 22, Jan 5, Jan 20) on nitrogen, phosphorus, potassium contents to evaluate flower characteristics and yield in Kinnow mandarin plant. Samples were taken from leaves and nodes at 1, 3 and 5 wks after spraying. Results showed that, 3 wks after foliar application, the plants which receiving 1.5% urea had the high leaves nitrogen content (2.5%) on Dec 22., whereas the highest nitrogen content (1.73%) of the nodes was obtained in plants treated with 1.5% urea concentration on Dec 22. The highest amounts of potassium and phosphorus of leaves were reported under 1.5% urea concentration on the 30th of January. It also indicated that different concentrations of urea are capable of enhancing the number of flowers, promoting ovarian growth and boosting yield of the crop. The most effective promotion on plant characters had been appeared on the rate of 1.5% urea concentrations.
