Does the corn girl break or not?

Some corn growers will choose to break off the corn girl, and a small number of corn growers will not break the girl. So whether the corn girl will break or not? Let's take a look.

First, whether the corn girl will break or not.

Corn can be broken or not, because the number of girls who can take the stick is relatively small, which will not have a great impact on the absorption of nutrients by corn. But the labor cost of breaking off the corn girl is relatively high, if you find that there is a corn girl, you can break it off; the girl has already exceeded the main stalk to break off; the girl on the edge of the ground is ready to break off to ensure the overall ventilation and light transmittance.

Second, what is the advantage of breaking up with the corn girl?

The main results are as follows: 1. The study on increasing the overall leaf area of maize shows that the leaf area of the experimental maize without tillering is 3561046510 square meters per hectare, while the leaf area of the untillering maize is only 24690 square meters per hectare. The former is much larger than the latter, which lays a good foundation for corn to produce more dry matter.

2. The determination of root system by root coefficient showed that the average number of roots per plant was 56, while that of decapitated plants was 29, with an average increase of 27.6, that is, an increase of 95%.

3. The evaporation of soil moisture is reduced and the soil water content is 14.49% higher than that at the surface of 10 cm. The formation of a larger leaf canopy reduces the evaporation of soil moisture and plays a role in maintaining soil moisture. It can be seen that in this case, leaf transpiration plays a more important role than surface evaporation, so it can maintain soil moisture and resist drought.

4. To cut off the top advantage, the main stem of corn with more girls is short and chubby in shape, and the more girls are, the less likely the main stem is to grow. The plant is short and fat is the sign of high yield!

5. The return of reproductive elements will gradually wither and die after maize heading, and the water, photosynthate and reproductive elements will flow back to the main stem, and finally provide nutrients for corn ripening.

Third, what's the harm in breaking up the corn girl?

1. If the corn girl is broken, it will form obvious trauma, which will not only cause the loss of water and nutrients, but also be easy to be infected with some diseases. And if the girl breaks up early, she will continue to grow in the later stage, in other words, more and more.

2. Maize is actually equivalent to the leaves of corn, so it can increase the overall leaf area of corn, improve photosynthesis, and is beneficial to the growth of corn.

3, the same corn girl has little effect on corn yield, but it takes a lot of manpower and material resources to break it off, so it is not cost-effective on the whole.

In fact, the corn girl can break it or not, if you see it, you can easily break it off. If you plant it in a large area, you can choose not to break it, which will have little impact on the corn.
