Description

Förderung des Pflanzenwachstums Zum Zwecke der Stimulation des Pflanzenwachstums bediente man sich bisher außer der Jauche auch gewisser anorganischer und organischer Verbindungen, z. B. Lösungsgemische einer Chinaldinverbindung und Magnesiumchlorid und Magnesiumsulfat. Bei anorganischen Salzen ist die stimulierende Wirkung noch bei Verdünnung von i zu wenigen Millionen zu bemerken, bei organischen Verbindungen ist die Wirksamkeit noch geringer. Auch Hormone pflanzlicher oder tierischer Herkunft, wie Sexual-, Hypophysen-und Thyreoidalhormone, wurden bereits als Stimulantien vorgeschlagen.Promoting plant growth For the purpose of stimulating plant growth In addition to liquid manure, certain inorganic and organic types have been used up to now Connections, e.g. B. Mixed solution of a quinaldine compound and magnesium chloride and magnesium sulfate. In the case of inorganic salts, the stimulating effect is still there noticeable when diluting i to a few million, in the case of organic compounds the effectiveness is even lower. Also hormones of vegetable or animal origin, such as sex, pituitary, and thyroid hormones, have already been suggested as stimulants.

Es wurde gefunden, daß die 3-Indol-essigsäure oder ihre Salze für das Pflanzenwachstum wichtige Stoffe sind. Während stärkere Konzentrationen eine Schädigung des Pflanzenwuchses bedingen, bewirken geringste Verdünnungen, z. B. i : i o11, eine deutliche Beschleunigung des Wachstums und eine verbesserteWurzelbildung gegenüber Kontrollen Schon bei Konzentrationen von etwa, i o% 3-Ind-olessigsäure treten praktisch keine Schädigungen auf. Es empfiehlt sich, die 3-Indvlessigsäure in Konzentrationen von i : J04 bis i : i o12 anzuwenden.It has been found that 3-indoleacetic acid or its salts for plant growth are important substances. While stronger concentrations one Cause damage to the vegetation, cause the slightest dilution, z. B. i: i o11, a significant acceleration of growth and improved root formation compared to controls, even at concentrations of about. 10% 3-indole acetic acid practically no damage occurs. It is recommended to use 3-indvlacetic acid to be used in concentrations from i: J04 to i: i o12.

Die 3-Indolessigsäure bzw. ihre Salze können gelöst im Gießwasser ,oder gemischt mit bzw. ;adsiorbiert ;an an sich bekannte Pflanz@ennähr-, -reiz- oder -beizstoffe und/oder aniorganischie oder organische Trägersubstanzen Verwendung finden. Z. B. kann man die 3-Indolessigsäure oder ihre Salze in Mischung mit den üblichen Düngesalzen, im besonderen Stickstoffdüngemitteln, ferner gemischt mit Kalk, Torf, Braunkohle usw. zur Anwendung bringen.The 3-indole acetic acid or its salts can be dissolved in the irrigation water , or mixed with or; adsorbed; plant nutrition, stimulation, known per se or pickling agents and / or aniorganischie or organic carrier substances use Find. For example, 3-indole acetic acid or its salts can be mixed with the usual fertilizer salts, in particular nitrogen fertilizers, also mixed with Apply lime, peat, lignite, etc.

Die wachstumfördernde Wirkung der j3-Indolessigsäure läßt sich z. B. in folgender Weise nachweisen: Haferkörner läßt man ankeimen und befestigt sie nach Austritt des Würzelchens über einer Wanne die l'"lährlbsung enthält, so daß die Würzelchen ;eben in die Flüssigkeit eintauchen und die Längenzunahmen der Keimlinge bequem meßbar sind. In die eine Wanne kommt als Kontrolle die Knopsche Nährlösung, in die andere dieselbe mit einem Zusatz von i mg (3-Indolessigsäure Auf i o5 1 Lösung. Unter täglicher Erneuerung der Nährlösungen läßt man die Keimlinge 6 Tage wachsen. Schon nach dieser Zeit zeigt sich, da.ß die mit 3-Ind@olessigsä.ure behandelten Keimlinge erheblich stärker gewachsen sind als die Kontrollen.The growth-promoting effect of j3-indole acetic acid can be z. B. prove in the following way: Oat grains germinate and fasten them after the root has emerged over a tub it contains the nutrient solution, so that the roots; just dip into the liquid and the length of the seedlings increases are easily measurable. The Knop nutrient solution is put into one of the tubs as a control, in the other the same with an addition of i mg (3-indoleacetic acid on i o5 1 solution. The seedlings are allowed to grow for 6 days with daily renewal of the nutrient solutions. After this time it is already evident that those treated with 3-Ind@olessigsä.ure Seedlings grew considerably faster than the controls.

An Stelle der 3-Indolessigsäure kann man auch ihre Salze, z. B. das Natrium-, Kaliumloder Calciunsalz, verwenden, deren Wirksamkeit ihrem Gehalt an 3-Indolessigsätireentspricht.Instead of 3-indole acetic acid, you can also use its salts, e.g. B. that Use sodium, potassium or calcium salts, whose effectiveness depends on their content 3-indole acetic acid.

In der Jauche ist zwar 3-Indolessigsäure enthalten, und man hat daher von der stimulierenden Wirkung dieser Substanz bei der Jauchedüngung -unbewußt Gebrauch gemacht. Die Regel, 3-Indolessigsäure als pflanzen- wachstumstimulierendes Mittel zu =verwenden, war jedoch nicht .daraus zu entnehmen. Es war auch erst auf Grund der der vorliegen- den Erfindung zugrunde liegenden Erkenntnis' möglich, die ß-Indolessigsäure in ,die Klasse. der hormoxlakn Pflänzenwuchsstoffe einzu- reihen, so daß die Anregung, Sexual- und andere Hormone ,als Stimulantien des Pflan- zenwachstums zu verwenden, zu vorliegender Erfindung nichts beitragen konnte. The manure does contain 3-indole acetic acid, and therefore the stimulating effect of this substance has been used unconsciously in manure fertilization. The rule to use 3-indole acetic acid as a vegetable to = use growth stimulating agent, but was not to be inferred from it. It was also only due to the knowledge underlying the invention ' possible to put the ß-indole acetic acid in that class. the hormoxlakn plant growth substances ranks so that the stimulation, sexual and hormones other than plant stimulants to use zen growth, to the present Invention could not contribute anything.
