China's current corn planting area is still relatively wide, so what do you want to do to grow corn and increase corn production? First of all, the growers need to manage the corn seedlings. Let's take a look at the management points of the corn seedlings.
1. Prepare for transplanting in advance
After the corn has emerged in succession, the growers' friends should check the emergence of the corn in time, and once it is found that the seedlings are broken, it is necessary to replenish the seedlings in time.
2. Master the seedlings and seedling time
The seedlings and seedlings are generally carried out when the corn grows to 3-4 leaves, and the weak, white, yellow, sick, inferior, and miscellaneous seedlings are removed. When the seedlings are set, the land can be kept a little closer to give full play to the marginal advantage. When the seedlings are fixed, the seedlings to be removed should be cleared out of the field in time. The time between seedlings and seedlings should be in the sunny afternoon. Those seedlings, insect bites and dysplastic seedlings are more likely to wilted in the afternoon, which is easy to identify and eliminate. Those silk seedlings with dense seedlings, dense, fine, curved, black-green leaves should be completely removed.
3. Master the time of seedlings to promote growth
Corn seedlings should follow the principle of "small black, not yellow, fat, not thin, damp and not dry". That is to say, the leaves are dark green, fertile, and strong. Otherwise, it will not be embarrassing. For the field where the growth of the seedlings is weak, not only the seedlings should be carried out, but also the fertilizer and water measures should be taken in time to promote the seedlings to grow stronger.
4. Pest control
There are many types of pests in corn seedlings, especially summer maize. At present, the main pests that harm corn at the seedling stage include earth tigers, aphids, thrips, cotton bollworms, and wheat straw flies.
The above is the management measures for the corn seedling period. Of course, in addition to these, there are weeding and fertilizing. As long as the growers have done a good job in the week, the growth of the corn will not be bad.
