大豆用バイオプレパレーション リゾフミン (泥炭)

Rhizohumin is a biofertilizer used for bacterization of soybean seeds to improve nitrogen nutrition of plants and increase crop productivity. The preparation includes specially prepared peat with bacterial cells of two strains of Bradyrhizobium japonicum propagated in it with different growth rates, physiologically active substances of biological origin (auxins, cytokinins, amino acids, humic acids), trace elements in chelated form and macroelement compounds in starting concentrations.
Biological action
The biological preparation has a multifunctional effect on the growth and development of plants. It provides an increase in field germination and seed germination energy, promotes the formation of a developed root system and active plant-bacterial nitrogen-fixing symbiosis, intensifies the process of photosynthesis in plants. Due to this, inoculated plants have an increased area of the assimilation surface of both roots and ground mass, which positively affects the absorption of nutrients. In addition, as a result of the active activity of the introduced bacteria, plants receive additional nitrogen and phosphorus nutrition. The preparation actively affects the formation of generative organs, contributes to a significant increase in the seed productivity of the crop. The use of two highly effective strains of Bradyrhizobium japonicum in the biological preparation contributes not only to an increase in crop yield, but also to the formation of a stable active population of rhizobia in the soil. This population can be considered as insurance, as it will ensure the formation of symbiosis in years unfavorable for the introduction and functioning of inoculant strains. The sum of these functions provides a guaranteed reliable increase in yield, and the resulting products have improved quality parameters. The complex effect of the drug on the soybean production process allows us to recommend its use not only in new soybean growing areas. A reliable inoculation effect is also provided when growing crops on soils with a high density of populations of aboriginal nodule bacteria.
Efficiency
Soybean grain yield when using Rhizohumin increases by 30-50% when growing the crop in new places and by 20-25% with a dense aboriginal population of nodule bacteria in the soil.
Method of administration and doses
To process 1 ton of soybean seeds, 2 kg of the drug is required.
For seed treatment, the drug is suspended in tap water that does not contain chlorine. The optimal amount of water should not exceed 0.8-1.0% of the seed weight. An increase in the proportion of water in the suspension is undesirable due to possible swelling and injury to the seeds. The drug is added to the calculated amount of water, mixed thoroughly and immediately bacterized on the day of sowing (or 1-2 days before) using machines such as PK-20 Super, PKS-20 Super, PK-20-02 Super, similar to the treatment according to the instructions for the machine. The machine must first be thoroughly cleaned of residues of treatment agents.
Rhizohumin is allowed to be used with fungicides Maxim XL 035 FS, Fundazol, Vitavax-200FF, which are applied 7-10 days before seed bacterization. In case of simultaneous use, the dose of the drug must be increased by 2 times. The use of herbicides leads to a phytotoxic effect on plants and a delay in the formation of legume-rhizobial symbiosis, so they must be introduced into the soil in advance.
Precautions
Do not allow direct sunlight to fall on the drug, prepared suspension and bacterized seeds.
Storage
Shelf life 6 months. Maximum storage temperature 10 degrees.
