From jointing to heading, corn must not only grow vegetative organs, but also differentiate between male and female ear, vegetative growth and reproductive growth, and have the greatest demand for water nutrients. Especially in the big bell period reached its peak. At this time, fertilization and irrigation should be performed according to soil and weather conditions. Due to the low temperature in the early stage, slow growth of the spring corn, adequate basal fertilizer, slow absorption rate of fertilizer, fertilization should be postponed until the big bell-mouth period. This fertilizer should account for 60%-70% of all fertilization, and it can also concentrate all the topdressing once in the big bell mouth period. General application of urea 20-25 kg per mu. Back to the corn and interplanting corn, because of short growth period, has been in the post-emergence: high temperature season, the previous period (emergence to tasseling) has consumed more than half of all nutrients, to the big bell-mouth period, should be planned fertilizer Once applied, urea is generally 25-30 kg per mu. Irrigation should be performed at the same time according to factors such as soil moisture content, rainfall, corn plant morphology, and other factors. When the soil moisture content is less than 70%-80% of the maximum water holding capacity in the field, the lower leaves of the corn are wilted at noon, and in the early evening, they are suitable for watering.
