The invention relates to a method for promoting growth, nodulation and nitrogen fixation of indigofera pseudotinctoria by utilizing rhizobium D303 and a bacterial solution thereof. The biological preservation number of the rhizobium sp. D303 is CCTCC (China Center for Type Culture Collection) NO: M20252803. Pot culture tie-back tests prove that the indigofera pseudotinctoria seedlings inoculated with the rhizobium are obviously superior to a control group in the aspects of plant height, root length, overground dry weight, underground dry weight, root nodule number, root nodule weight, root nodule diameter, nitrogenase activity, antioxidant enzyme activity and the like. The rhizobium strain provided by the invention has efficient nodulation and nitrogen fixation capability and excellent growth promoting characteristic, obviously improves the growth speed, nodulation capability and nitrogen fixation efficiency of the indigofera pseudotinctoria, reduces the dependence on chemical nitrogen fertilizer, and has a broad application prospect in development of special biological bacterial fertilizer for indigofera pseudotinctoria. The method has important ecological and economic benefits for promoting the application of the indigofera pseudotinctoria in ecological restoration and feed production, and is suitable for slope greening, water and soil conservation and barren mountain ecological restoration projects.

The utility model relates to the technical field of slope greening protection, and disclose a kind of slope greening protection structure, including slope, and protection assembly and irrigation subassembly are arranged on the slope upper side;Irrigation subassembly is located above protection assembly, and the protection assembly includes the first galvanized iron wire, second galvanized iron wire, third galvanized iron wire and fourth galvanized iron wire located above slope.The grid structure formed by the first galvanized iron wire, second galvanized iron wire, third galvanized iron wire and fourth galvanized iron wire reduces the slope maintenance requirement due to wind and rain erosion, and the fixing mode of pressing plate and ground nail, effectively enhances the stability of slope, prevents rock collapse and slope instability, and the use of planting bag makes vegetation recovery more direct and efficient, and the substrate ratio garden soil in planting bag provides a good soil environment for vegetation growth, so as to not only realize the stability of slope, but also improve the ecological and landscape value of slope through the planting of vegetation.

The invention is suitable for the technical field of agricultural automation equipment, and provides a ridge sealing crop field operation trolley based on a dual-camera recognition system, and the ridge sealing crop field operation trolley comprises a crawler-type chassis, and further comprises a multi-degree-of-freedom adjusting module, a dual-pesticide-chamber pesticide supply module, a dual-camera visual module and a control unit. According to the device, through cooperative perception of the global vision unit and the local vision unit and combination of flexible operation of multi-axis machinery and classified pesticide application, the problems that the field view of ridge sealing crops is limited, the operation precision is low, and the types of weeds cannot be accurately recognized are effectively solved; the device has the advantages of compact structure, high adaptability, high pesticide utilization rate, accurate and efficient operation and the like.
