This year is too dry. Can corn seedlings control their growth?

It is an important means to dwarf the plant height, strengthen the stalk, promote the root development, enhance the weather resistance of corn, prevent lodging and ensure the yield and stability of corn in the later stage. The corn stalk without dawang element is thin and weak, and it is easy to cause lodging and yield reduction when encountering heavy rain in the middle and late stage. Last year, the weather was too dry, and some people said that there were few corn seedlings, so there was no need to control the prosperous factors. So, this year, the villagers had experience. Last year, we agreed to play again this year. Last year, they didn't play. Seeing that other people's homes are good, I have gained a lot, and I also said that I played this year. They really play with different roots.
