Влияние частоты полива на рост и урожайность Taraxacum kok-saghyz Rodin

Taraxacum kok-saghyz – одно из самых перспективных каучуконосных растений . Недостаточно изучено влияние полива на урожайность и биохимический состав кок-сагыза. В исследовании изучалось влияние частоты полива на рост и урожайность Taraxacum kok-saghyz. Согласно полученным результатам было установлено, что увеличение частоты полива (увеличение интервала полива) постепенно снижало содержание каучука и общий выход сахара у кок-сагыза. С увеличением содержания воды в почве с 22,8 до 38,9% выход каучука и сахара существенно менялся в соответствии с кубической зависимостью (уравнением кубического полинома). Регулярный полив один раз в 6 дней поддерживает влажность почвы на уровне 28%, что позволяет увеличить урожайность кок-сагыза при одновременном повышении эффективности водопользования в условиях северо-восточного Китая (Харбин).
