Description

Verfahren zum Frühtreiben von Pflanzen Es ist bekannt, das Frühtreiben von Pflanzen durch Einwirken gasförmiger Blausäure hervorzurufen, die nach dem Bottich-Verfahren oder auch aus zersetzlichen Cyaniden gewonnen sein kann.Method for early forcing of plants It is known that early forcing caused by plants by the action of gaseous hydrocyanic acid, which is produced by the vat method or can also be obtained from decomposable cyanides.

Es bat sich herausgestellt, daß die Wirkung der Blausäure erheblich gesteigert wird, wenn die Einwirkung gleichzeitig mit anderen Frühtreibmitteln geschieht. Diese gleichzeitige Einwirkung kann in einfachster Weise derart erzielt werden, daß Gemische oder Verbindungen zur Anwendung gelangen, die außer Blausäure noch ein oder mehrere frühtreibende Gase, wie Ammoniak, Acetylen u. ä., .entwickeln.It turned out that the effect of hydrogen cyanide was considerable is increased if the action occurs at the same time as other early propellants. This simultaneous action can be achieved in the simplest way in such a way that that mixtures or compounds are used which, in addition to hydrocyanic acid, are used develop one or more propellant gases such as ammonia, acetylene and the like.

Für die gleichzeitige Einwirkung von Blausäure und Acetylen läßt sich rohes Calciumcyanid verwenden, das aus über Carbid hergestelltem Kalkstickstoff eventuell unter weiterer Zugabe von Carbd beim Schmelzprozeß erzeugt wird. In diesem rohen Cyaniid .ist immer Carbid vorhanden. Unter der Einwirkung von feuchter Luft entwickelt das Produkt Blausäure und Acetylen, .so daß durch die Kombination der sich verschieden verhaltenden Treibmittel Blausäure und Acetylen eine besonders günstige Wirkung erzeugt wird.For the simultaneous action of hydrocyanic acid and acetylene can be Use raw calcium cyanide, which is made from calcium cyanamide produced via carbide possibly produced with further addition of carbide during the melting process. In this crude cyanide, carbide is always present. Under the action of moist air developed the product hydrocyanic acid and acetylene, so that by combining the Propellants, hydrocyanic acid and acetylene, which behave differently, are particularly one beneficial effect is generated.

Für die gleichzeitige Entwicklung von Blausäure und Ammoniak benutzt man z. B. aus ammoniakalischen Lösungen durch Verdampfen oder Kristal#l:isieren erhaltene Cyanide. Diese Cyanide enthalten immer gebundenes Ammoniak, ,das bei der Verwendung langsam mit (der Blauisäure abgegeben wird. Man erhält solche Cyani.de z. B. durch Reaktion der Komponenten oder durch doppelte Umsetzung der Salzlösungen mit Ammoncyanid in flüssigem Ammoniak. Besonders geeignet .sind die Salze der Zusammensetzung Ca (CN NH3), oder Mg (CN NHs)2, aber auch alle andern entsprechenden Salze der Erdalkalien. können verwendet werden, wobei es in keiner Weise auf die Einhaltung des stöchiometrischen Verhältnisses ankommt.Used for the simultaneous development of hydrogen cyanide and ammonia one z. B. from ammoniacal solutions by evaporation or crystal # l: ize obtained cyanides. These cyanides always contain bound ammonia, which in the Use slowly with (the blue acid is released. You get such Cyani.de z. B. by reaction of the components or by double conversion of the salt solutions with ammon cyanide in liquid ammonia. The salts of the composition are particularly suitable Ca (CN NH3), or Mg (CN NHs) 2, but also all other corresponding salts of the alkaline earths. can be used, whereby it in no way affects compliance with the stoichiometric Relationship matters.

Ein großer Vorteil .der Verwendung solcher zersetzlichen Cyanide"die Carbid, Ammoniak oder Ammoniak entwickelnde Stickstoffverbindungen enthalten, besteht darin, daß diese Verbindungen vielfach. bei der Herstellung als Rohprodukte anfallen und keiner weiteren Reinigung bedürfen, da sie gerade in der Form des unreinen Rohprodukts besonders günstige Wirkungen entfalten.A great advantage of "the use of such decomposable cyanides" Contain carbide, ammonia or ammonia-evolving nitrogen compounds in that these connections are multiple. arise as raw products during manufacture and do not require any further purification, as they are precisely in the form of the impure crude product develop particularly beneficial effects.
