New Technology for Presowing Treatment and Seeding of Common Pine Seeds in the Nursery

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.
