When will the corn be planted? Explain the causes and solutions of the dead seedlings in detail!

Corn, also known as Baogu, is a common crop in our country, which is planted by almost every household. It is widely planted because of its wide application value, simple planting and low investment cost. When will corn be planted? What happened to the dead seedling?

1. Introduction to corn:

1. Is corn a hot or cool food?

Corn is a hot food with low energy, so it can effectively accelerate gastrointestinal peristalsis and promote weight loss. People who lose weight generally like to take it as their main meal. Of course, some people also specialize in growing and raising poultry.

2. Is corn coarse grain?

Corn is coarse grain, is also fine grain, because corn has many uses, in addition to grinding into flour, corn dregs, it can also be eaten directly, if it is directly eaten undamaged is coarse grain, if it is processed into corn meal, corn dregs and other products is fine grain, so it is difficult to say whether coarse grain is not easy to say, it depends on how you use it.

When will the corn be planted?

In general, corn is planted in spring and autumn, but the planting will be different due to local climate differences, the specific planting time is as follows:

1. Spring planting time: generally sowing from late April to early May and harvesting in late August. However, the northeast region is generally planted in mid-late April and can not be harvested until October.

2. The planting time in autumn is mid-July and harvested in mid-late October.

3. The rest of the planting time: planting from late March to early April, for example, planting in Shandong area in early April, waiting for harvest in late August or September, and planting in late March to early April in the south, and harvesting in early July.

Third, what is the matter with the dead corn seedlings?

First, excessive fertilization: corn has a high demand for fertilizer, but it does not mean that it needs a lot of fertilizer, and it generally requires a high amount of fertilizer during the growing period, so try to apply some nitrogen fertilizer during the growing period, but if it is directly sprinkled on the root or seedling, it will burn the root and cause the seedling to die.

Solution: if it is just emerging and died soon, pull up the seedling in time, replant some, but if it is dead during the growing period, plant some other crops. It is worth noting that in the later stage of fertilization, formula fertilizer must be used and sprinkled in a timely and appropriate amount away from the root, so that the seedlings will not die.

Second, too high temperature leads to water shortage: corn needs more water, especially at heading stage, so it should be watered more during this period. In addition, more water should be watered at high temperature in summer, otherwise drought and water shortage will lead to dead seedlings.

Solution: water more during heading and dry and hot seasons, so as not to cause dead seedlings due to lack of water. It is worth noting that watering in the morning and evening in summer high temperature weather can not only cool down, but also supply water in time.

Third, the impact of diseases and insect pests: during the growth of corn, there will be root rot, brown spot, seedling blight, aphids, ground tigers and other diseases and insect pests, these diseases and insect pests can lead to dead seedlings.

Solution: dead seedlings are few and light, and special agents can be selected for spraying and control. if the dead seedlings are serious and die soon after emergence, the seedlings can be pulled out in time and replanted, but if they are dead during the growing period, plant some other crops. In addition, when selecting seeds, try to select some seeds with strong disease resistance, high temperature resistance and drought resistance, and disinfect the seeds before planting, so that the occurrence of diseases and insect pests can be reduced, and the phenomenon of dead seedlings and yellowing leaves will not occur.

Fourth, too much spraying or improper use: during the growth of corn, some pesticides need to be sprayed to control a variety of diseases and insect pests, but if sprayed too much or improper use, there will be the phenomenon of dead seedlings.

Solution: if the seedlings died shortly after emergence, they can be pulled out in time and replanted, but if they died during the growing period, plant some other crops. In addition, when spraying pesticides in the later stage, try to operate according to the instructions, and the concentration should not be too high, so that the seedlings will not die, and the efficacy can be well played.

The above is a detailed introduction of the planting time of corn and the solution to the cause of seedling death. I hope it will be helpful to you.
