چکیده
Соя (Glycine max (L.) Merr.) является ведущей культурой среди бобовых и ее востребованность в мире ежегодно растает. Для Казахстана соя стратегической культурой, так как позволяет снизить дефицит белка питании людей животных. Однако урожайность сои Республике по сравнению с другими странами низкая. Из-за низкой урожайности производство становится нерентабельным. повышения продуктивности применяют минеральные азотные удобрения, что создает опасность для окружающей среды. Решением проблемы применение биоудобрений на основе клубеньковых бактерий, которые фиксируют азот атмосферы снабжают им растения. Целью данного исследования было выделение нового штамма бактерий высокой азотфиксирующей активностью, способного увеличивать всхожесть семян, эффективно образовывать клубеньки корнях сои, стимулировать рост повышать урожайностьсои. Из клубеньков растений собранных полях Алматинской области Казахстана, выделен высокоэффективный штамм Bradyrhizobium japonicum Н7, способный большое количество клубеньков, активно фиксировать молекулярный атмосферы, улучшать азотное питание сои. В полевых условиях установлено, инокуляция штаммом Н7 увеличивает семян до 90%, повышает густоту посевов 26–30%, высоту - 25%, а 9-11 ц/га. Таким образом, можно использовать создания бактериального удобрения культуры Soybean is the leading crop among legumes and its demand in world will melt away every year. For Kazakhstan, soybean a strategic crop, as it allows to reduce protein deficiency nutrition of people animals. However, productivity Kazakhstan low compared other countries. Due yields, production becomes unprofitable. To increase soybeans, mineral nitrogen fertilizers are used, which pose threat environment. The solution problem improving soybeans use biofertilizers based on rhizobia, fix atmospheric supply plants. goal this study was isolate novel strain rhizobia with high nitrogen-fixing activity, effectively forming nodules roots, increasing seed germination, promoting growth productivity. From roots plants collected fields Almaty region highly effective H7 isolated. forms large number nodules, actively fixes molecular nitrogen, improves increases yield. Under field conditions, found that inoculation germination seeds up seeding density by 26-30%, plant length c/ha. Thus, can be used create bacterial fertilizer for culture.

MATERIALS AND METHODS Sulfate translocation in soybean (Glycine max L. Merr) was investigated. More than 90% of the sulfate entering the shoot system was recoverable in one or two developing trifoliate leaves. In young plants, the first trifoliate leaf contained between 10 to 20 times as much sulfate as the primary leaves, even though both types of leaf had similar rates of transpiration and ph...
