In terms of grain harvesting machinery, Western developed countries have basically completed the upgrading of mechanized grain harvesting in the past half century. The level of grain harvesting machinery in China not only requires the direct harvest of grain, but also the rate of damage, the rate of falling seeds, and Harvesting speed, barrier-free working hours, logistical services, and security systems have reached a high level of “advanced advantageâ€. At the same time as harvesting grain, the machinery should also have a variety of capabilities to handle the straw - either smashed directly to the field, or packaged for biofuels, or harvested as a yellow storage, etc., not only to help farmers obtain multiple benefits, but also help solve Increasingly prominent environmental issues.
In supporting industries, grain drying towers and steel silos are the most important for grain harvesting. About 25% of the grain can't be put into storage directly after harvest, and must go through a drying process. At present, China's drying tower technology and equipment are relatively mature, and the amount of money required for each set of drying towers is also very limited. Therefore, from the perspective of industrial development, the capacity of warehousing and drying should be increased to make it compatible with the production areas of corn. Layout and production match.
In addition, the grain collection and storage process also needs to be adjusted accordingly. At present, every year the State Reserve opens and closes food receipts before and after the end of the year. In the past, most of the harvested corn cobs were manually harvested, then air-dried and threshed. The time of opening the warehouses had little effect on the acquisition of grain. However, under the conditions of mechanized harvesting of grain and drying, the first batch of new grains could be listed in early October. If you do not start purchasing and storage, there will be a large backlog of new grain and the industry will come to a standstill. It does not say that it will cause huge losses, but it will also hurt farmers’ enthusiasm for production. Therefore, in order to adapt to the rapid development of mechanized grain harvesting new trends, the storage time of State Reserve Grain should be greatly advanced.
In short, corn grain harvesting is definitely not an adjustment of simple breeding characteristics, but a change in the direction of industrial development. This change requires adjustments, changes, cooperation, and support in all aspects of the entire industry chain, supporting industries, and industrial policies.
