大豆——根瘤菌——菌根真菌联合共生对大豆生产具有重要意义,接种根瘤菌能扩大氮肥来源、接种菌根真菌有助于作物从土壤中吸取更多的磷素,应用这两项生物技术可改善大豆氮磷营养、提高土壤肥料利用率,是作物走向自身从空中取氮,向土壤索磷的新方向。 土壤中存在着大量的土著根瘤菌和菌根真菌,要选择高效根瘤菌和菌根菌与之共生,
Soybean - rhizobium - mycorrhizal fungi joint symbiosis is of great significance to soybean production, inoculation rhizobium can expand the source of nitrogen, inoculated mycorrhizal fungi help crops to draw more phosphorus from the soil, the application of these two organisms Technology can improve nitrogen and phosphorus soybean nutrition, improve soil fertilizer utilization, is the crop to its own from the air to nitrogen, to the soil for a new direction of phosphorus. Soil exists in a large number of indigenous rhizobium and mycorrhizal fungi, to choose efficient rhizobia and mycorrhizal symbiotic,
