Wholly mechanized integrated cultivation method for Chinese little greens

The invention relates to a wholly mechanized integrated cultivation method (shown in abstract figure) for Chinese little greens, and the wholly mechanized integrated cultivation method is organically combined with agricultural machinery measures and agronomic measures during production. The method mainly comprises the following steps: screening and classifying seeds, performing fine soil preparation and bedding, performing precision seeding and repressing, and mechanically harvesting; because the Chinese little greens are short in a growth period, soil physical and chemical properties are improved by deeply digging so that the proper growth environment can be created for the growth of the Chinese little greens; after the seeds of the Chinese little greens are screened by a gravity screening machine, the germination rate, germination potential and seedling rate of the seed can be obviously improved, thereby establishing the foundation for mechanization harvesting. The wholly mechanized integrated cultivation method is characterized in that corresponding agronomic measures are assorted when fine soil preparation and suitable sowing date are ensured, so that the soil environment can be effectively improved; the Chinese little greens are timely harvested in good time, and thus the labor cost is reduced and the labor efficiency is obviously increased.
