Abstract
Die Erfindung betrifft ein Mittel zur Minderung von Immissionsschaeden an Gehoelzen. Ziel der Erfindung ist es, Schaedigungen des Baumbestands durch Immissionen zu senken. Aufgabe der Erfindung ist es, ein weiteres chemisches Mittel anzugeben, bei dessen Verwendung die behandelten Pflanzen chronische Immissionen tolerieren und sich nach Beendigung der Immission schnell erholen. Es wurde ueberraschend gefunden, dass chemische Mittel, die Thiocyanate, vorzugsweise dissoziierende Thiocyanate, wie Natrium-, Kalium- und Ammoniumsalze, einzeln oder in Kombination enthalten, die gestellte Aufgabe loesen.The invention relates to a means for reducing Immissionsschaeden to Gehoelzen. The aim of the invention is to reduce damage to the tree population by immissions. The object of the invention is to provide a further chemical agent, in the use of which the treated plants tolerate chronic immissions and recover rapidly after termination of the immission. It has surprisingly been found that chemical agents containing thiocyanates, preferably dissociating thiocyanates, such as sodium, potassium and ammonium salts, individually or in combination, solve the stated object.
Description
Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betrifft ein Mittel zur Minderung von Immissionsschäden an Gehölzen.The invention relates to a means for reducing immissions damage to woody plants.
Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions
Anpassungsmaßnahmen der Forstwirtschaft gegen Immissionsschäden gründen sich in der Regel auf die allgemeine ungerichtete Steigerung der Vitalität der gefährdeten Baumarten durch den Schutz vor biotischen Schädlingen, Düngung, Vermeidung bzw. Minderung mikroklimatischer Extremwerte mit Hilfe eines entsprechenden Waldaufbaus. Der Verzicht auf immisionsgefährdete, wirtschaftlich meist kaum ersetzbare Baumart ist oft unvermeidlich. OBYDJONNY beschreibt Versuche zur Minderung von SO2-Schädigungen durch Applikation wasserlöslicher Schwermetallverbindungen. Obydjonny, P.T. (Schutz der Wälder vor Industrieabgasen. In Lesnoje Chosjaistwo, 1977,6, S.35 bis 38) Erprobt wurden V, Co, Cd, Hg, Cr, Th und Ag. Als Mindestgabe empfiehlt er 8g Schwermetall pro ha und Jahr mit Erhöhung um jeweils4g bei jeder Steigerung der Immissionskonzentration um 0,15mg SO2/m3 bis maximal 50g/ha.Adaptation measures of forestry against immission damage are generally based on the general undirected increase in the vitality of the endangered tree species by the protection against biotic pests, fertilization, avoidance or reduction of microclimatic extreme values with the help of a corresponding forest structure. The abandonment of immi- demally endangered, economically hardly replaceable tree species is often inevitable. OBYDJONNY describes attempts to reduce SO2 damage by applying water-soluble heavy metal compounds. Obydjonny, P.T. (Protection of Forests from Industrial Exhaust Gases., Lesnoje Chosjaistwo, 1977, 6, pp. 35-38) V, Co, Cd, Hg, Cr, Th and Ag were tested. As a minimum he recommends 8g heavy metal per ha and year with an increase of 4g each with an increase of the immission concentration by 0.15mg SO2 / m3 up to a maximum of 50g / ha.

Darlegung des Wesens der ErfindungExplanation of the essence of the invention
Aufgabe der Erfindung ist es, ein weiteres chemisches Mittel anzugeben, bei dessen Verwendung die behandelten Pflanzen . chronische Immissionen tolerieren und sich nach Beendigung der Immission schnell erholen.The object of the invention is to provide a further chemical agent, in its use, the treated plants. tolerate chronic immissions and recover quickly after the immission has ceased.
Es wurde überraschend gefunden, daß chemisch Mittel, die Thiocyanate, vorzugsweise dissoziierende Thiocyanate, wie Natrium-, Kalium- und Ammoniumsalze, einzeln oder in Kombination enthalten, die gestellte Aufgabe lösen.It has surprisingly been found that chemically agents containing thiocyanates, preferably dissociating thiocyanates, such as sodium, potassium and ammonium salts, individually or in combination, solve the stated object.
Je nach Immissionsbelastung empfiehlt sich ein Einsatz von 0,1 bis 50kg/ha.Depending on the pollution load, an application of 0.1 to 50 kg / ha is recommended.
Ausführungsbeispielembodiment
Vierjährige Fichtenjungpflanzen wurden durch Gießen mit 20mg Natriumthiocyanat pro kg Boden (ca. 30kg/ha) erfindungsgemäß behandelt und anschließend 5 Monate mit 0,8mg SO2 je m3 begast. Im Vergleich zu unbehandelten Kontrollpflanzen wiesen sie danach eine um 20% höhere Photosyntheserate und einen um 92% gesteigerten Prolingehalt aus. 9 Monate nach der Begasung hatten die begasten und erfindungsgemäß behandelten Pflanzen denselben Prolingehalt wie nicht begaste und unbehandelte Kontrollpflanzen. Die Pflanzen hatten sich also vollkommen erholt. Der Gehalt an Chlorophyll, als ein Ausdruck guter Vitalität, war um 65 bis 73% höher als bei den unbehandelten Pflanzen.Four-year old spruce plants were treated by casting with 20 mg sodium thiocyanate per kg soil (about 30 kg / ha) according to the invention and then fumigated for 5 months with 0.8 mg SO2 per m3. Compared to untreated control plants, they showed a 20% higher rate of photosynthesis and a 92% increase in proline content. 9 months after fumigation, the fumigated and treated according to the invention plants had the same proline content as non-fumigated and untreated control plants. The plants had completely recovered. The content of chlorophyll, as an expression of good vitality, was 65 to 73% higher than that of untreated plants.
