چکیده

برای بررسی اثر پلیمر آبدوست ترآوت آ 200 و میزان رطوبت خاک بر برخی صفات خیار گلخانه‌ای رقم سلطان، آزمایشی به‌صورت فاکتوریل در قالب طرح کاملاً تصادفی انجام شد. پلیمر آبدوست در پنج سطح (صفر، 1/0، 2/0، 3/0 و 4/0 درصد بر اساس وزن خشک خاک به ترتیب معادل 0، 1، 2، 3 و 4 گرم در کیلوگرم خاک) و مقدار رطوبت خاک در سه سطح (100، 75 و 50 درصد ظرفیت زراعی) بررسی گردید. نتایج نشان داد که کاربرد پلیمر آبدوست در خاک بر ارتفاع گیاه و تعداد برگ در گیاه تاثیر مثبت و معناداری داشت. پلیمر آبدوست بر محصول نوبرانه و عملکرد کل خیار تأثیر معناداری نداشت. تیمار مقدار رطوبت خاک بر تمام صفات مورد مطالعه تأثیر معنا‌داری داشت. بیشترین ارتفاع گیاه، تعداد برگ در گیاه، وزن تر و خشک اندام هوایی گیاه، وزن تر و خشک ریشه، محصول نوبرانه و عملکرد کل در تیمار 100 درصد ظرفیت زراعی و کمترین آن در تیمار 50 درصد ظرفیت زراعی به‌دست آمد. تیمار 75 درصد ظرفیت زراعی نتایج حد واسطی داد. بنابراین کاربرد پلیمر آبدوست تراوت آ 200 به میزان 4 گرم در کیلوگرم خاک (4/0 درصد) همراه با رطوبت خاک تا 75 درصد ظرفیت زراعی برای رشد، محصول نوبرانه و عملکرد قابل قبول خیار گلخانه‌ای رقم سلطان توصیه می‌شود.

چکیده [English]

To investigate the effect of terath A 200 hydrophilic polymer and the amount of soil moisture on some traits of greenhouse cucumber of Sultan cultivar, a factorial experiment was conducted in a completely randomized design. Hydrophilic polymer in five levels (zero, 0.1, 0.2, 0.3 and 0.4% based on soil dry weight equal to 0, 1, 2, 3 and 4 g.kg soil, respectively) and the amount of soil moisture At three levels (100, 75 and 50% of field capacity) were studied. The results showed that the application of hydrophilic polymer in soil had a positive and significant effect on plant height and number of leaves per plant. Hydrophilic polymer had no significant effect on fresh product and total cucumber yield. Treatment of soil moisture had a significant effect on all studied traits. The highest plant height, number of leaves per plant, fresh and dry weight of plant shoots, fresh and dry weight of roots, new crop and total yield were obtained in 100% field capacity treatment and the lowest in 50% field capacity treatment. Treatment of 75% of field capacity gave intermediate results. Therefore, the use of Trout A200 hydrophilic polymer at the rate of 4 g / kg soil (0.4%) with soil moisture up to 75% of field capacity is recommended for growth, new crop and acceptable yield of greenhouse cucumbers of Sultan cultivar.
