Технологія вирощування стандартних сіянців сосни звичайної в умовах закритого ґрунту

Abstract

На підставі проведених досліджень доведено як густота вирощування сіянців в умовах закритого ґрунту впливала на лінійні показники посадкового матеріалу сосни звичайної. Проведено аналіз, як густота вирощування сіянців впливала на вагові показники. У результаті досліджень з вирощування однорічних сіянців сосни звичайної в плівковій теплиці розраховано оптимальну норму висіву для отримання максимального виходу стандартного садивного матеріалу

На основании проведенных исследований доказано как густота выращивания сеянцев в условиях закрытого грунта влияла на их линейные показатели. В результате исследований по выращиванию однолетних сеянцев в закрытом грунте рассчитано оптимальную норму высева для получения максимального выхода стандартного посадочного материала

It is known that practically 100 % of the greenhouse seedlings reaches to the end of the growing season in height standard size, which is not the diameter. Reducing the rate of planting has a positive effect, first and foremost, on indicators such as the mass of shoots and roots and growth of the root collar diameters. Also, greenhouse conditions can significantly improve the germination, resulting in application rate for the open ground is unacceptable and recommendations for specific greenhouse climate conditions are not designed forestry. The urgency of the issue increases due to the transition of forestry on the basis of breeding and using for the cultivation of planting material genetically improved seeds. For sowing the seeds of pinus silvestris took 1 class, penned in forestry. Seed tape before planting watered with a solution of liquid Bordeaux at the rate of 0.5 liters per 1 m. Sowing seeds carried out manually. The seeding rate on experimental plots was under the experimental scheme. On the remaining area the greenhouse seeding rate has been generally accepted – at the rate of 3.0 g (300 pcs.) At 1 m immediately after seeding paved the irrigation system and atomized spent watering.. Biometric indicators of Scots pine seedlings – seedling height, root collar diameter, length of the root system – affect the quality of planting material and its survival during landing in culture and must comply with the standard. According to the standard, the height of the seedlings first grade pine should be at least 15 cm, thickness of root collar at least 3 mm, length of the root system at least 20 cm height pine seedlings the second grade. Not less than 10 cm, thickness 2-3 mm root collar, the length of the root system of 15-20 cm. As a result of studies on the cultivation of annual seedlings of Scots pine in the film greenhouses are invited to sow the seeds of the norm of 250 and 200 pieces/м. Under these rules seed produced the highest yield of standard planting material with high linear weighted indicators and quality indicators. The primary benefit of the planting material obtained by a seeding rate, provide it greater vitality in the silvicultural area
