Problems solved by technology

However, the current production is mainly cultivated in spring and autumn. The fresh corn cultivated in autumn generally ends in the market in mid-October. When it is mature, the fresh-keeping period is short. If it is not harvested in time, the quality will deteriorate and lose its edible value, which will affect farmers' income.
The fresh corn on the market after mid-October is produced in the south and transported to the local market after long distances. The quality has declined significantly and the edible value is not high, so it is not popular with the public.
