DD247142A1 - METHOD FOR INCREASING BIOLOGICAL TISSFIT FIXATION OF ROTKLEE BY MEANS OF RHIZOBIUM BACTERIA - Google Patents

Abstract

The process according to the invention relates to the use of the rhizobium bacterial strain ZIMET 11163 to red clover, with the aid of which atmospheric nitrogen is fixed. It is demonstrated without additional Stickstoffduengung Mehrertraege of dry matter and crude protein in Gefaess- and field trials.

Claims (2)

Invention claim: T. A method for increasing the biological air nitrogen fixation in red clover using Rhizobium bacteria, characterized in that the red clover seed is treated before sowing with the rhizobium bacterial strain ZIMET 11163. 2. The method according to item 1, characterized in that preferably a peat preparation is used as a carrier substance. Field of application of the invention The invention can be used in plant production. Characteristic of the known technical solutions There are known methods in which by means of Rhizobium bacteria and other microorganisms on the fixation of the atmospheric nitrogen dry matter and / or crude protein yield of various crops, especially legumes, without additional use of nitrogen fertilizers can be increased (eg SU-UHS 698968,874724 et al ). However, the specific performance of the microorganisms with respect to increasing the dry matter and / or crude protein yield in individual crops and the resistance to soil antagonistic microorganisms is still insufficient. Object of the invention The aim of the invention is to increase the dry matter and / or crude protein yield of red clover without the additional use of nitrogen fertilizers. Explanation of the essence of the invention The object of the invention is to increase the dry matter and / or crude protein yield of red clover without additional nitrogenous fertilizers by the use of Rhizobium bacteria, which are competitive against wild population and soil antagonistic microorganisms, compared to known strains. The object is achieved in that the red clover seed is treated before sowing with the rhizobium bacteria of the strain ZIMET 11163. This strain of Rhizobium bacteria is able to fix more nitrogen in the air and provide it to the plants than known strains. The cultivation of the rhizobium bacterial strain ZIMET11163 is preferably carried out on a peat carrier. The seedbed can also be vaccinated with the Rhizobium bacterial strain. By atmospheric nitrogen fixation using the rhizobium bacteria, the dry matter and crude protein yield is increased over known strains both in vascular as well as in field and large-scale experiments. The application of the method has the advantage that nitrogen fertilizers can be saved or higher yields can be achieved with the same amount of nitrogen. embodiment The invention will be explained in more detail by way of example. The following results were obtained by treating the red clover seed with the rhizobium bacterial strain ZIMET11163 on a peat carrier layer: Table 1: Dry matter and crude protein yield of red clover after application of the rhizobium bacterium strain ZIMET 11163 in a pot experiment
