The latest reasons affecting Maize yield

The planting area of corn in China is still relatively broad, and the emergence of hybrid corn has raised the yield of corn to another level, and the annual yield of corn is getting better and better, which is related to many reasons. Well, what we need to understand today is the reasons that affect corn yield, but there are many reasons that affect corn yield, so here are some more important reasons. Let's take a look.

1. Variety selection

At present, there are a variety of maize varieties, and the resistance of each variety is also different, such as strong drought resistance, disease resistance, cold resistance, flood resistance and so on. Among them, whether the variety selection is correct or not is the most basic reason that affects the maize yield, in order to improve the maize yield, so that the maize yield is not affected by variety factors, then we need to choose varieties according to the various factors of the location of corn planting.

2. Planting conditions

The effect of planting conditions on maize yield is mainly shown in the three aspects of temperature, soil and light, because if the planting conditions are not conducive to the growth of corn, then no matter how good the variety is, it will not make up for it. Therefore, planting conditions are also an important factor affecting maize yield, but also the basic conditions for corn growth, so we need to choose a suitable planting land for planting.

3. Density management

If there are no problems in the above two basic conditions, then the planting density will also affect the yield of corn, because the growth of corn needs a certain amount of light, so if the planting density is too large, then the field will appear more gloomy, thus affecting the growth of corn, and finally affecting the yield of corn. There is also the reason that too much density affects pollination, which eventually leads to a reduction in corn production. If planted at a normal density, the corn cob will be much larger and the yield of corn will be increased.

4. Water and fertilizer management

Water and fertilizer is a key reason that affects corn yield. We usually increase corn yield by strengthening the management of water and fertilizer. If there is too much water in the field, corn seedlings will rot and other diseases will occur. This will reduce corn production. Secondly, if there is too little water, the corn seedlings will dry out, which will also lead to yield reduction, and then if excessive fertilization or improper use of fertilizer. Will lead to a reduction in corn production, and less fertilization will lead to corn malnutrition, resulting in a reduction in yield.

5. Weeding management

Weeding is an important step in maize planting. We all know that weeding can promote the growth of maize roots and seedlings. At the same time, it can also promote the growth of corn cobs and, to a certain extent, enhance the resistance of corn. Thus, the yield of corn can be increased, but if weeding is not carried out reasonably in the process of corn planting, it will first lead to nutrient loss, and secondly, it will lead to a lot of insect pests. Then the growth rate of corn slows down, missing the best fruit period and ripening period, resulting in a reduction in corn production.

6. Disease management

In fact, there are many diseases and insect pests in the whole growing period of corn, once the vigilance is relaxed and the prevention and control is not in place, then the damage to corn is very great, because it is not only the impact on a single corn, but also on the whole piece of corn. So disease management is also an important reason that affects corn yield.
