Description

Verwendung von Schwermetallkomplexsalzen als Mikronährstoffe Zur Aufrechterhaltung eines normalen, gesunden Wachstums benötigt die Pflanze neben den hauptsächlichen Nährstoffen eine Reihe von sogenannten Spurenelementen oder Mikronährstbffen, die jeweils nur in sehr geringen Mengen vorhanden zu sein brauchen. Diesen einzelnen Spurenelementen kommt eine maßgebliche katalytische Funktion bei den Wachstumsprozessen zu. Ihr Fehlen im Boden hat Mangelerscheinungen an den Pflanzen und Ertragsminderungen zur Folge.Use of heavy metal complex salts as micronutrients for maintenance normal, healthy growth is what the plant needs in addition to the main ones Nutrients a number of so-called trace elements or micronutrients that only need to be present in very small quantities. This individual Trace elements play a crucial catalytic role in the growth processes to. Their absence in the soil results in deficiency symptoms in the plants and reduced yields result.

Solche Mangelerscheinungen an Pflanzen, die jeweils charakteristisch für das Fehlen eines bestimmten Elements sind, lassen sich in bekannter Weise durch Einbringen entsprechender Salze in den Boden oder auch durch Behandlung der Blätter mit ihnen beheben, wobei dieser letzteren Form der Spurenelementzufuhr der Vorzug gegeben wird, da hierbei wesentlich geringere Mengen an den entsprechenden Salzen aufzuwenden sind.Such deficiency symptoms in plants, each characteristic for the absence of a certain element can be passed through in a known manner Introducing appropriate salts into the soil or by treating the leaves fix with them, the latter being the form of trace element intake the Preference is given, since in this case significantly smaller amounts of the corresponding Salts are to be used.

Es ist bekannt, daß man zur Beseitigung von Nikronährstoffmangelerscheinungen an Pflanzen anorganische Metallsalze verwenden kann, daß aber auch organische Verbindungen, die das Metall, z. B. zweiwertiges Eisen, Mangan oder Kupfer, in komplexgebundener Form enthalten, geeignet sind.It is known that one can help eliminate nicronutrient deficiencies can use inorganic metal salts on plants, but also organic compounds, which the metal, e.g. B. divalent iron, manganese or copper, in complex-bound Form included, are suitable.

Es wurde gefunden, daß zur Behebung der genannten Mangelerscheinungen die jeweiligen Schwermetalle vorteilhaft in Form von Komplexsalzen angewendet werden, deren Molekül i, 2-Diaminocyclohexan zugrunde liegt. Infolge des mehr lipophilen Charakters der Blattoberfläche erlaubt diese ein sehr viel leichteres Eindringen dieser Komplexsalze als dies bei Anwendung der entsprechenden anorganischen Salze der Fall ist.It has been found that to remedy the deficiency symptoms mentioned the respective heavy metals are advantageously used in the form of complex salts, whose molecule is based on i, 2-diaminocyclohexane. As a result of the more lipophilic The nature of the leaf surface allows it to penetrate much more easily these complex salts than when using the corresponding inorganic salts the case is.

So erweisen sich beispielsweise Lösungen des Kupferdinatriumsalzes der i, 2-Diaminocyclohexantetraessigsäure oder des Mangandinatriumsalzes der i, 2-Diarninocyclohexantetraessigsäure den die gleichen Mengen von Kupfer oder Mangan enthaltenden Lösungen von Kupfersulfat oder Mangansulfat als eindeutig überlegen. Die entsprechenden Komplexverbindungen des zweiwertigen Eisens lassen sich in gleicher Weise über das Blatt zwecks Behebung chlorotischer Mangelerscheinungen zuführen.For example, solutions of the copper disodium salt are found in this way the i, 2-diaminocyclohexanetetraacetic acid or the manganese sodium salt of the i, 2-Diarninocyclohexanetetraacetic acid denies the same amounts of copper or manganese containing solutions of copper sulfate or manganese sulfate as clearly superior. The corresponding complex compounds of divalent iron can be used in the same way Apply via the leaf to eliminate chlorotic deficiency symptoms.

In der- Tabelle sind die Ergebnisse von in Gefäßen durchgeführten Vegetationsversuchen zusammengestellt. Diese Versuche betreffen die Zuführung des Kupferdinatriumsalzes bzw. des Mangandinatriumsalzen der i, 2-Diaminocyclohexantetraessigsäure durch Besprühen der Blätter und im Vergleich hierzu die Zuführung von Kupfersulfat bzw. Mangansulfat einerseits durch Besprühung der Blätter und andererseits durch Einführen in den Boden. Das Kupferkomplexsalz wurde als 0,36- bzw. o,45°/oige wäßrige Lösung, das Mangankomplexsalz als I,3o°/oige wäßrige Lösung angewandt, während CuS04 - 5 H20räls 6,2-bzw. 0,25°%igewäßrige Lösung und Mn SO, - Hz O als 0,5 °/oige wäßrige Lösung zur Anwendung kam.The results of vegetation tests carried out in pots are compiled in the table. These attempts concern the supply of the copper disodium salt or the manganese sodium salt of i, 2-diaminocyclohexanetetraacetic acid by spraying the leaves and, in comparison, the supply of copper sulfate or manganese sulfate on the one hand by spraying the leaves and on the other hand by introducing it into the soil. The copper complex salt was used as a 0.36 or 0.45% aqueous solution, the manganese complex salt as a 1.3o% aqueous solution, while CuSO4-5 H20 was 6.2 or. 0.25% aqueous solution and Mn SO, - Hz O as 0.5 % aqueous solution was used.
