Influence of seeding rates seeds at exit standard seedlings pine in indoor growing

Investigations to determine the output of standard pine seedlings at different seeding rate of pine seeds in the greenhouse conditions. For the cultivation of seedlings it was used as a substrate of peat bogs transition milling work piece with a dose of application of mineral fertilizers, N70P150K 90. Pine seeds were sown in Egedal a scatter planter beds with a width of one meter seeding rates of 6.8; 11.0; 14.0 g/m 2. To estimate the output of seedlings that meet regulatory requirements, use trial-analysis based on a normal distribution. With the increase of pine seed sowing rate was observed decrease in the yield percent of standard seedlings and increase custom. It is not noted a significant change in percent yield seedlings height of 7 cm. With seeding rate is 6.8 g/m 2 output of standard seedlings was 94.5%, while and 14.0 g/m 2 – 88.4%. Significant changes were observed in the output of larger seedlings 12 cm. When seeding rate of 6.8 g/m 2 yield was 57.9%, with 11.0 g/m 2 – 46.0%, and at 14.0 g/m 2 – 27.2%. Therefore, the indoor planting pine material should be grown in a medium-density plantings with a seeding rate of 11–12 g per 1 m 2, which will be combined with economical consumption of seeds with an optimal output of standard planting material
