Four Attentions for Corn Selection
The first selection criterion is to be suitable for the corn planted in the local accumulated temperature, and many farmers buy seeds that cross the accumulated temperature for high yield.
Second, we need to see whether the seeds are full and the color is normal. Farmers know that the seeds are gray or gray or have worm-eaten or aged seeds. We generally do not choose such seeds because the germination rate is not good To guarantee.
Third, we must choose corn seeds with even grains, because the size of corn seeds is directly related to the time of corn emergence. Large corn seeds will emerge more slowly because larger seeds need to absorb more water to germinate. Small seeds need less water and germinate faster. At the same time, it should be noted that small seeds should be properly sown and large seeds should be sown deeply. Therefore, in order to make the emergence time as neat as possible, the size of the seeds should be strictly controlled.
Fourth, we have to see whether the seeds have mildew and high damage rate. If there are seeds with high mildew and damage rate, we will not preferentially choose them in principle.
