At present, according to China's existing multiple corn harvesters, the following points should be noted in the selection:

First, first consider the applicability of the region. Due to the different planting time of corn in different places, the harvesting time is also different. There are flat broadcast, ridge broadcast, furrow sowing, and sowing, seeding and other forms. So when choosing a model, consider the applicable type in your area.

Second, we must consider the issue of investment income. The current corn harvester is mainly self-propelled, traction and backpack. The self-propelled model is large, the price is relatively expensive, and the investment recovery period is longer; the towing model is longer and does not adapt to small plots. The piggyback can use existing tractors. The investment is relatively small at one time, the benefits are also good, and the mobility and operability of the operation are good. Therefore, the existing users generally use the backpack type.

Third, we must consider the power of supporting. At present, tractors equipped with corn harvesters are all over 50 horsepower. Farmers must match their existing tractor power when selecting corn harvesters. They should avoid “small horse-drawn carts” and “big horse-drawn carts”. The phenomenon.

Fourth, we must consider the way of straw treatment. The treatment of corn stalks mainly includes smashing and returning to the field, burying the whole stalk, recycling the whole stalk, and crushing and recycling it as silage or green manure. The existing corn combine harvesters are equipped with straw smashing and returning machines. With the continuous development of animal husbandry, the demand for corn straw as a feed is also increasing.
