In addition to the fundamental changes in corn varieties, supporting machinery, facilities and industrial development, business processes and industrial policies will also be adjusted accordingly.
In terms of grain harvesting machinery, Western developed countries have basically completed the upgrading of mechanized harvested seeds nearly half a century ago. The level of grain harvesting machinery in China requires not only the ability to directly harvest kernels, but also the rate of breakage, seed drop rate, Harvest speed, barrier-free working hours, logistics services and support systems have reached a high level of “post-development advantageâ€. At the same time as harvesting the grain, the machine should have the ability to handle the straw at the same time – or smash it directly into the field, or package it for use as a biofuel, or harvest it as a yellow stock, which will help the farmers to obtain multiple benefits and help solve the problem. Increasingly prominent environmental issues.
In the supporting industry, the most important thing for grain harvesting is the grain drying tower and the steel silo. About 25% of the kernels cannot be directly stored in the warehouse after harvesting, and must be subjected to a drying process. At present, China's drying tower technology and equipment are relatively mature, and the amount of each drying tower is also very limited. Therefore, from the perspective of industrial development, the storage and drying capacity should be increased to make it compatible with the corn producing areas. The layout matches the output.
In addition, the grain storage process also needs to be adjusted accordingly. At present, the annual storage of grain by the State Reserve is around the end of the year. In the past, most of them were artificially harvested corn cobs, then aired and threshed. The opening time had little effect on grain purchases. However, under the conditions of mechanized harvesting of grain and drying, the first batch of new grains could be marketed in early October. If you do not start collecting and storing, it will cause a large backlog of new grain, and the industry will come to a standstill. If you cause huge losses, it will also hurt the enthusiasm of the farmers. Therefore, in order to adapt to the rapid development of mechanized grain harvesting new trend, the opening time of the national grain storage should be greatly advanced.
In short, the grain harvest of corn is definitely not a simple adjustment of breeding characteristics, but a change in the direction of industrial development. This change requires all aspects of the entire industry chain, all aspects of supporting industries, and adjustment, change, cooperation and support of industrial policies.
