Abstract
Изобретение относитс к лесному хоз йству. Применение известного эмульгатора, диспергатора и стабилизатора - твина-80 в концентрации 0,3 и 1% позвол ет защитить пни сосны на 96-99% от заражени спорами корневой губки через 2-3 года после обработки, в то врем как защита пней на 21% может быть достигнута при использовании 5% раствора буры. 1 табл.The invention relates to forestry. The use of a known emulsifier, dispersant and stabilizer - Tween-80 at a concentration of 0.3 and 1% protects pine stumps by 96-99% from infection by sponge root spores 2-3 years after treatment, while protection of stumps is 21 % can be achieved using a 5% borax solution. 1 tab.
Description
Изобретение относитс к лесному хоз йству , а именно к химическим средствам борьбы с грибными заболевани ми сосны.The invention relates to forestry, in particular to chemical means of controlling pine fungus diseases.
Цель изобретени - увеличение фунги- цидной активности средства.The purpose of the invention is to increase the fungicidal activity of the agent.
Обрабатывают свежие пни сосны в 12- летней восприимчивой культуре сосны после первой рубки ухода линейно-селекционным Способом. Определ ют балл смоловыделе- ни . Обработку провод т в период массового заражени пней спорами корневой губки - в теплую сырую погоду в окт бре мес це. Результаты защиты пней провер ют через 2 года. Процент предотвращени заражени пней определ ют по разнице между контролем (без обработки) и опытом. Результаты представлены в таблице.Fresh pine stumps are processed in a 12-year-old susceptible pine culture after the first thinning with linear selection method. The score of resin release is determined. The treatment is carried out during the period of mass infection of stumps with sponge root spores - in warm, wet weather in October. The stump protection results are checked after 2 years. The percentage of stump infection prevention is determined by the difference between control (without treatment) and experience. The results are presented in the table.
Пни, обработанные сверху мочевиной, были заселены кукушкиным льном и лишайниками . В поверхностном слое пн (1-3 см) развивались грибы деструкторы p.Stereum.The stumps, treated with urea, were populated with cuckoo flax and lichen. In the surface layer of mon (1-3 cm), the p.Stereum destructors developed.
Пни, обработанные бурой,сверху грибами не засел лись, по боковым корн м в пен снизу заходила пестра ситова гниль от корневой губки.The stumps treated by the brown were not settled on top of the mushrooms, along the lateral roots the variegated sieve rot from the root sponge entered the foams below.
Данные проверки через 3 года совпадают с данными проверки через 2 года.The verification data after 3 years coincides with the inspection data after 2 years.
Годичный патологический отпад от корневой губки на секции с обработкой пней 5%-ной мочевиной составил 25 деревьев и 1,5 , 5%-ной бурой - 26 деревьев и 1,4 м /га, оксалатом аммони 5 деревьев и 0.3 , твином - 80 в 3%-ной концентрации отсутствует.One-year pathological loss of root sponge on the section with stump treatment with 5% urea was 25 trees and 1.5, 5% brown - 26 trees and 1.4 m / ha, ammonium oxalate 5 trees and 0.3, tween - 80 in 3% concentration is absent.
