根际細菌的数量组成及其与植物营养关系的研究,目前已为国际农业和土壤微生物学者所重視。由于植物根表和根附近的土壤中所存在的这些大量的、并有一定特殊性的微生物,不仅可以引起土壤中有机和无机化合物的轉化,分泌生长刺激物貭或抑制物貭以影响植物的营养和生长发育,并由根际微生物与作物的特殊关系,在制定轮作、土壤保健、施
The quantity and composition of rhizobacteria and their relationship with plant nutrition have been paid great attention to by international agricultural and soil microbiologists. Due to the large amount of certain and particular microorganisms present in the plant root and soil near the roots, not only can the transformation of organic and inorganic compounds in the soil be induced, the growth stimulants or inhibitors of growth can be secreted to affect plant Nutrition and growth and development, and by the rhizosphere of microorganisms and crop the special relationship between the development of crop rotation, soil health, Shi
