| چکیده | ||
| توسعه برداشت مکانیزه بعنوان یکی از راهکارهای اصلی برای کاهش 30 درصدی هزینه‌ها می تواند قدرت رقابت محصول پنبه را بالا برده و سبب حفظ این محصول در کشور گردد. برای برداشت ماشینی پنبه لازم است که قبل از برداشت از محلول‌های برگ ریز استفاده گردد تا محصول برداشت شده تمیز و با کیفیت باشد. به منظور بررسی اثر زمان پاشش برگ‌ریز و سرعت پیشروی ماشین برداشت وش‌چین پنبه بر کارکرد ماشین ، آزمایشی در سال زراعی 1393 در ایستگاه تحقیقاتی هاشم‌آباد گرگان به مورد اجرا گذاشته شد. فاکتور‌های مورد مطالعه در این تحقیق شامل دو زمان پاشش برگ‌ریز (70 و 90 درصد باز شدن غوزه‌ها)، دو رقم پنبه (گلستان و سپید) مناسب برداشت ماشینی و سه سرعت پیشروی (4/1، 2/5 و 2/7 کیلومتر بر ساعت) بودند. طرح آزمایشی مورد استفاده در این تحقیق، اسپلیت اسپلیت پلات در قالب بلوک‌های کاملا تصادفی، با سه فاکتور در سه تکرار می‌باشد. نتایج تحقیق حاضر نشان داد که زمان برداشت و سرعت بر کیفیت الیاف بی‌تاثیر بود. اثر رقم بر کیفیت الیاف معنی‌دار گردید، که این اهمیت انتخاب رقم مناسب برای برداشت مکانیزه را می‌رساند. رقم سپید از لحاظ شاخص کیفی الیاف نسبت به رقم گلستان برتری داشته و مناسب‌تر برای برداشت ماشینی است. | ||

| چکیده [English] | ||
| The development of mechanized harvesting as a way to reduce 30% the cost of production could raise the competitiveness of cotton production and maintain in the country. Using defoliator before machine harvesting is necessary to cleaning harvesting and high quality. To evaluate the effect of spraying time of defoliator and speed of cotton harvesting machine on machine performance and quality of cotton fiber, an experiment was carried out in Cotton Research Station of Hashemabad, Gorgan in 2014. The studied factors in this research were included two levels of spraying time of defoliator, two levels of cotton varieties suitable for mechanical harvesting and three levels of forward speed. The experimental design was split split plot in randomized complete block design with three replications and three factors. Results showed that harvesting time and speed did not affect the quality of the fiber. The effect of variety was significant on fiber quality, the importance of choosing the most suitable for mechanized harvesting of leads. Sepid variety in terms of quality index fibers had priority compared to the Golestan, and was suitable for machine harvesting. | ||
