Перспективность инкрустации семян органоминеральными композитами

Abstract

Увеличение площадей искусственного и естественного лесовосстановления и лесоразведения обусловливает необходимость в выращивании большого количества стандартного посадочного материала наиболее ценных древесных видов. Основной способ размножения хвойных видов – семенной. Однако нередко семена характеризуются низкой всхожестью, а также долгое время не выходят из состояния покоя, даже при создании оптимальных условий для прорастания, что увеличивает период выращивания сеянцев. Картина усугубляется периодичностью семенных лет, что создает опасность недостатка семян для выращивания посадочного материала и лесных культур посевом. В целях минимизации недостатка семян применяются способы стимулирования их прорастания, а также создания для каждого семени дополнительного запаса питательных веществ, что особенно важно при создании лесных культур. Нами предпринята попытка анализа влияния инкрустации (дражирования) семян рода ель (Picea Dietr.) на всхожесть и энергию их прорастания. Установлено, что проведение инкрустации семян органоминеральным композитом позволяет сократить расход семян на 6–12 % при выращивании одинакового количества посадочного материала. Кроме того, инкрустация обеспечивает сокращение периода прорастания семян на 2–3 недели, что особенно важно при выращивании нескольких ротаций сеянцев с закрытой корневой системой. The increase in the areas of artifi cial and natural reforestation and afforestation necessitates the cultivation of a large amount of standard planting material of the most valuable tree species. The main method of reproduction of coniferous species is seed. However, seeds are often characterized by low germination, and they do not leave the dormant state for a long time, even when optimal conditions for germination are created, which increases the period of growing seedlings. The situation is aggravated by the periodicity of seed years, which creates the risk of a shortage of seeds for growing planting material and forest crops by sowing. In order to minimize the shortage of seeds, methods are used to stimulate their germination, as well as to create an additional supply of nutrients for each seed, which is especially important when creating forest crops. We have attempted to analyze the effect of incrustation (coating) of seeds of the genus Spruce (Picea Dietr.) on their germination capacity and energy. It has been established that incrustation of seeds with an organomineral composite allows to reduce seed consumption by 6–12 % when growing the same amount of planting material. In addition, incrustation ensures a reduction in the seed germination period by 2–3 weeks, which is especially important when growing several rotations of seedlings with a closed root system.
