Plant growth promoting rhizobacteria (PGPR) are a group of bacteria that can increase plant growth; but due to unfavorable environmental conditions, PGPR are biologically unstable and their survival rates in soil are limited. Therefore, the suitable application of PGPR as a plant growth stimulation is one of the significant challenges in agriculture. This study presents an intelligent formulation based on VRU1 encapsulation enriched with nanoparticles that was able to control on the bean. The spherical structure of the capsule was observed based on the Scanning Electron Microscope image. Results indicated that with increasing gelatin concentration, the swelling ratio and moisture content were increased; and since the highest encapsulation efficiency and bacterial release were observed at a gelatin concentration of 1.5%, this concentration was considered in mixture with alginate for encapsulation. The application of this formulation which is based on encapsulation and nanotechnology appears to be a promising technique to deliver PGPR in soil and is more effective for plants.
植物促生根际细菌（PGPR）是一类可以促进植物生长的细菌；但由于环境条件不利，PGPR 在生物上不稳定，其在土壤中的存活率有限。因此，将 PGPR 作为植物生长刺激物的适当应用是农业中的重大挑战之一。本研究提出了一种基于 VRU1 包封的智能制剂，该制剂富含纳米颗粒，能够控制豆类的生长。基于扫描电子显微镜图像观察到胶囊的球形结构。结果表明，随着明胶浓度的增加，溶胀率和水分含量增加；并且由于在明胶浓度为 1.5%时观察到最高的包封效率和细菌释放，因此在与藻酸盐混合进行包封时考虑了该浓度。这种基于包封和纳米技术的制剂的应用似乎是一种在土壤中输送 PGPR 的有前途的技术，对植物更有效。
