Background Sustainable development of agricultural production increasingly depends on innovative application of biotechnology, wherein a symbiotic nitrogen fixation system of leguminous crops and rhizobia is a key natural mechanism for reducing chemical nitrogen fertilizer application and improving soil fertility. The efficient and reliable inoculation of rhizobia into legume seeds is the first step in initiating this reciprocal symbiotic relationship, and the quality of inoculation directly determines the early nodulation efficiency and final yield of crops. Therefore, the development of intelligent seeding equipment capable of realizing high activity maintenance and accurate and uniform package of the microbial inoculum has become an important front edge for the development of modern fine agricultural technology, and has huge economic benefit and ecological value. Currently, the prior art schemes for seed inoculation in the industry fall into two main categories. Firstly, the technology of pre-dressing seeds, namely, a plurality of hours or even days before sowing, the rhizobium inoculant of liquid or peat carriers and seeds are mixed in batches in a fixed container in advance, and the seeds are dried for standby. Secondly, the online spraying technology is adopted, the scheme is usually integrated on a seeder, and a simple seed metering device is combined with a spraying system, so that the microbial inoculum is continuously or regularly sprayed on the surface of seeds in the process of falling the seeds, and then directly enters the soil. However, the prior art has the defects that firstly, for the technology of pre-mixing seed, the microbial inoculum is exposed to multiple stresses such as drying, temperature fluctuation, ultraviolet irradiation and the like during the storage and waiting period from the mixing of the microbial inoculum and seeds to the sowing, the activity of the microbial inoculum is greatly attenuated, the field inoculation effect is seriously affected when the microbial inoculum is sown, secondly, the wrapping uniformity of the microbial inoculum on the surface of each seed cannot be ensured no matter the microbial inoculum is pre-mixed or simply sprayed on line, and particularly for the bean seeds with irregular shapes, the concave and side surfaces of the microbial inoculum are often not covered enough, and a remarkable shadow effect exists. In addition, the simple online spraying system lacks accurate trigger mechanism, easily causes the waste of bacterial agent and field cross contamination, and can't drive the seed to roll in the parcel intracavity initiatively, causes parcel homogeneity highly to rely on the random gesture when the seed whereabouts, and the reliability is not good, and these defects have restricted agronomic effect and economic benefits that prior art can reach jointly.
