What fertilizer is better for wheat water?

Generally, 5 kg of urea is applied per mu. Wet tillage and wet planting of yellow seedling wheat field, 8- 10 kg diammonium phosphate per mu is enough. The application amount of turning green manure should not be too large to avoid lodging; Generally, green manure is not applied to wheat fields with suitable population and normal leaf color. Nitrogen fertilizer is the main topdressing of wheat. When applying 40-5ojin of compound fertilizer per mu of wheat, we should observe the seedling situation around March in the solar calendar, and generally topdressing urea1ojin, and topdressing is less for over-prosperous wheat seedlings.

As we all know, the turning green period of wheat is the first key growth period in spring after a winter. The reason for this turning green period is that wheat stopped growing all winter, and the leaves of wheat gradually turned green, and began to grow again from the turning green period. Phosphorus is most needed at booting stage, and potassium fertilizer is most needed at flowering and filling stage. Therefore, nitrogen topdressing can meet the needs of rapid tillering and ear formation of wheat, and also provide reserve nutrients for the rapid increase of nitrogen demand after jointing.

Light topdressing, less green manure. When applying green manure, it should be combined with the growth of seedlings, and the soil fertility should be flexibly balanced. Only by quantitative topdressing according to the growth of seedlings can the expected effect be achieved, otherwise, there will be phenomena of virtual growth, lodging and late maturity. An acre of land is about 20-30 kg (it can be increased or decreased according to the specific situation). Urea is a high concentration nitrogen fertilizer, which can effectively promote the growth of wheat. In addition, from the cost point of view, it is relatively cheap and suitable for the normal growth of wheat. About twenty or thirty kilograms per mu is enough. Urea has fast fertilizer efficiency and can be used as topdressing. However, in a very contradictory place, farmers often start watering green water while applying anti-green manure. Urea is very soluble in water, which is washed away by irrigation water and needs more fertilization. The time to turn green varies from region to region. The turning green period of wheat is the main period of rooting, growing leaves and tillering. We must do a good job in wheat management during this period to ensure the smooth turning green and the safe growth of the turned green wheat.
