Corn land tillers too much, that is, commonly known as the long "yazi", which means the competition for light, water, nutrient resources, then corn "yazi" should not be broken?
First, the corn "yakuza" should not be broken
In fact, in addition to the seeds and weather rain these factors, the biggest reason is because of too much nutrients, that is, nitrogen fertilizer (urea) is used more, now everyone likes to topdress, topdressing period can be applied urea, urea effect comes too fast, inevitably caused by excess nutrition.
What to do? Corn also has a trick, just divide the two out, that is, "Yazi", put the excess nutrients into the "Yazi" first, so that the excess nutrients are diverted.
Second, the benefits of "yazi"
1. Increase the overall leaf area of corn.
2. Added root coefficient. The determination of roots showed that the average number of tillers was 56, while the number of tillers was 29, an average increase of 27.6, that is, an increase of 95%.
3. Reduce the evaporation of soil moisture.
4. All the main stems of corn with more "yazi" are short and thick in form, and the more "yazi", the less likely the main stem is to grow. Short and thick plants are the signs of a good yield!
5. "Yazi" will gradually wither and die after the corn is extracted, and the water, photosynthetic products, and reproductive elements in it will flow back to the main stem, and finally provide nutrients for the maturity of corn, and the "Yazi" will naturally wither.
Third, in the end, do you need to break it?
Breaking the "yazi" is a kind of harm to the plant, in the process of self-repair of the plant, the probability of disease and insect invasion and fungal infection will increase.
Professor of Shenyang Agricultural University, Vice Chairman of Northeast Special Maize Research Association, Member of Liaoning Provincial Crop Variety Approval Committee. Shi Zhensheng, director of the Special Research Institute of Agricultural University, told everyone that the phenomenon of corn growing "yazi" is now relatively common, and the differences between corn varieties are relatively large, some varieties of "yazi" are more numerous and larger, and some varieties of "yazi" are small. The principle of whether the corn "yazi" is not broken off in the end is: observe whether the "yazi" affects the growth of the main stem, if the main stem of the "yazi" grows well, and the main stem of the long "yazi" is not good and is affected, then the "yazi" is recommended to break it. However, breaking the "yazi" does not have to be very clean and thorough, it is recommended to break off the first growing "yazi" or the two larger "yazi" on both sides of the base, and then grow out of the need to break off again, and the future will not affect the growth of the main stem.
So, does the corn "yazi" need to be broken?
The biggest role of the corn "Yazi" is to retain nutrients for the main stem, and when the main stem nutrients are not enough, the "Yazi" will return the nutrients to the main stem, and finally the "Yazi" will also wither, so you are not breaking the "Yazi", it is to throw away the nutrients. The corn "yakuza" has little effect on the main stem. So the corn grows "yakuza" without bothering to break it, just let it fend for itself!
