Опыт интенсивного выращивания однолетних сеянцев сосны обыкновенной в Павлодарской области Республики Казахстан

Abstract

The studies were conducted in State Forest Natural Reserve “Ertis Ormany” in Pavlodar region by the example of one-year-old seedlings of Pinus sylvestris L. The experiments were laid out by pre-sowing preparation of the seeds with the use of stimulants Baikal, Humate+7, Zircon and fungicide Trichocyne as well as by adding of the growth substances (Agroperlite, AridGrow, KZ Culture and KZ Soil, Humate Phosphate, Trichocin, Trichoderma, Nitrogen and Phosphorus) into soil before and after sowing of the seeds. The average value of laboratory viability in experiment on soaking of the seeds in stimulants exceeded control for 5 %, in experiment on combined use of stimulants and fungicide – for 3.5 %. From all the performed experiments, the biggest average height (8.1 cm) was at seedlings in experiment under watering of the soil by growth substances after sowing of the seeds and at the use of covering material “Agrotex”. What is more, some specimens on the first year of life reached the height of 13 cm that corresponds to the indices of standard planting material. All the variants of the experiment exceeded control on height in 2.0–2.4 times. Seedlings in the analogous experiment by watering of the soil by growth substances, but without covering of the crops considerably lagged in growth and the average height was 4.8 cm. Application of dry fertilizers before sowing of the seeds positively influenced the intensity of growth of one-year-old seedlings which reached the average height of 4.9 cm. By complex of studied qualitative indices of growth of one-year-old seedlings it was determined that the rational way of growing the planting material for conditions of Pavlodar region is watering of the soil by “AridGrow”, Trichoderma and Trichocyne with the subsequent covering of the crops by “Agrotex”. Application of biological fungicides positively influenced the intensity of growth of the plants. It should be marked that the seedlings which grew under the covering material had the largest indices of overground and underground parts of the plants in comparison with all the other experiments. Besides, the pre-sowing processing of the seeds of Pinus sylvestris L. by Zircon (6 hours) and Humatophosphate (12 hours) in combination with Trichocyne (2 hours) is recommended.For citation: Kabanova S.A, Danchenko M.A., Kochegarov I.S.,.
