If the number of basic seedlings in the field is appropriate, the density of the wheat seedlings is caused by the excessive growth of the wheat seedlings and the excessive amount of tillers. Through suppression, the growth of shoots in the wheat seedlings can be effectively inhibited, and the occurrence of tillers can be suppressed and the population can be controlled. If the density of wheat seedlings is caused by too many basic seedlings, repression can control the population to grow too fast to a certain extent, but the control effect is relatively poor. The repression measures can usually be taken at any time before and during wintering of wheat. When soil moisture is too high in the field, it should be suppressed when soil moisture is suitable. Wheat seedlings cannot be suppressed when the soil is frozen.
