Usmanova G. Agroecological bases of phosphorus-fixing bacteria's usage at oily cultures growing.

In this work there were shown the results of investigation as for albobacterin and polymyxobacterin usage at rape and sunflower growing technology. It was established that inoculation of these oily cultures' seeds with phosphorus mobilizing bacteria preparations ensures plants' growing and development, intensificates the processes connected with phosphorus and nitrogen feeding of plants as well as causes rise of rape's and sunflower's productivity and makes better their quality. Bioenergetics' and economic expediency of albobacterin and polymyxobacterin usage rape and sunflower sowing was analyzed. It was shown that introduction of Achromobacter album 1122 and Paenobacillus polymyxa KB into rape's and sunflower's rizosphere influences positively microbiothenos condition, increasing nitrogen-fixing activity of associative microflora about 1,7-6,9 times. It was established that when producing the preparations for increasing titre and the term of storage it expedient to use solid mineral helping ceolit (0.5%). New forms of preparations have the same influence on plants as their existing forms.
