ABSTRACT

When reforestation is cut down for various needs of our country coniferous forests significantly reduced their quality, mainly due to the fact that they are poorly renewed. One of the reasons for this is the low quality of seed material, harvested usually not from the testes and plus trees, but from trees with low genetic characteristics of trees. In the resulting seed mix to contain different fractions of seeds differing in seed quality. When sowing such heterogeneous seeds in a forest nursery at the end of the growing season, a significant part of the grown seedlings (up to 30 %) goes to marriage, because they do not meet the requirements of the standard. This is because, contained in the total mass of small seeds do not have the growth potential that large, and when they grow together, seedlings grown from small seeds do not meet the requirements of the standard, because in the process of growth and development are oppressed by larger seedlings. The new technology for sizing pine seeds allows you to completely separate the fractions of small seeds. Sowing small seeds separately from large ones at the optimal depth of planting, you can create conditions for their effective growth and development, as well as provide additional planting material that meets the requirements of the standard.

ВВЕДЕНИЕ

Огромную роль в деле лесовоспроизводства в нашей стране и во всем мире играет качество семенного материала. Для получения высококлассных семян необходимо иметь эффективные средства механизации по обескрыливанию, очистке, сортированию и калиброванию лесосеменного сырья. Пневмоочистка и последующее калибрование лесосеменного сырья являются одними из важнейших и завершающих операций при получении качественного семенного материала.

Применяемые в нашей стране и за рубежом различные способы и технические средства для сортирования и калибрования лесных семян недостаточно совершенны и не отвечают в полной мере основным требованиям, предъявляемым к качеству обработки [12].

Привлечение и использование сельскохозяйственной техники для этой цели не практикуется, а в отдельных случаях не дает желаемого результата. Это связано с тем, что лесные семена резко отличаются от семян сельскохозяйственных культур по физико-механическим и по технологическим характеристикам. Специальных исследований по этому важному вопросу не проведено, хотя процессу разделения семян уделяется большое внимание [11].
