JUSTIFICATION OF PARAMETERS OF MACHINE TECHNOLOGY OF ORGANO-BAKTERIAL FERTILIZERS PREPARATION
Abstract
Questions connected with a solution of a problem of providing plants with nitrogen by means of nitrogen-fixing biological preparations application were considered. Requirements to quality of organo-bacterial fertilizers preparation on the basis of composts and the nitrogen-fixing biological preparations of Extrasol group were stated. Theoretical and experimental researches for justification of possibility of biological products application together with peat-manure composts were conducted. A project of technological process and experimental facilities for organo-bacterial mix preparation with a set quality level of biological product distribution in compost were developed. In the course of experiment the time length of mixing was modified from 1 to 12 min. There were set the values of rotation frequency of a rotor mixer: 40, 60, 80 and 100 rpm. Uniformity of biological product distribution in the mix was estimated by coefficient of a variation of a control element for which sugar beet seeds were used. It was revealed that quality of biopreparation distribution in the compost mass depends on the rotor mixer rotation frequency and time length of mixing. At the constant mixing time with increase in frequency of rotation quality of distribution in the mass of the control element estimated by variation coefficient at first decreases, and then at achievement of the frequency of 65-70 rpm it starts to increase. Quality of distribution is influenced positively also by time length of mixing. With the constant frequency of rotor mixer rotation uniformity of mixing was stabilized after 3-4 min. When facilities loading to 50 kg of mix (49 kg of compost +1 kg of a biological product) the coefficient of a control element variation characterizing distribution quality made 10-13 percent with a frequency of rotation of 65 rpm and time of mixing of 3 min.
