根际微生物要对植物生长产生作用,首先应具有在根表定殖的能力。近年来的一些研究表明,在利用微生物防治植物病害时,最好筛选那些不仅对病原菌有颉颃作用,而且还能在植物体表或体内定殖的微生物。因此,弄清有关微生物在植物体表或体内的定殖能力和过程,具有重要的 Rhizosphere microorganisms have an effect on plant growth, first of all should have the ability to colonize the root table. In recent years, some studies have shown that in the use of microorganisms to control plant diseases, it is best to screen those that are not only antagonistic to pathogenic bacteria, but also in the plant surface or in vivo colonization of microorganisms. Therefore, it is important to understand the ability and process of colonization of microorganisms on the plant surface or in the body
