Wheat is now entering the nodulation period need to how to manage

Management of wheat nodulation period:

Normal growth of wheat, when the spring temperature rises above 10 ℃, the base of the wheat internodes began to elongate, internodes exposed to the ground 1.5-2.0cm is called nodulation.

Pulling fertilizer: The strong seedling field can be in the group leaf color fading, tiller number decline, the first internode close to the fixed length, according to the wheat seedling situation appropriate amount of pulling fertilizer. Generally in the main stem inverted 3-leaf period, the plant base of the second internode significant elongation, per mu of urea 6 ~ 8 kg, the application amount of total nitrogen application of 20% or less. Want seedling field wheat nodulation period leaf color does not fade, leaf blade drape, may not be applied or less nodulation fertilizer. Indeed need to apply the pulling fertilizer, should be delayed until the main stem inverted 2 leaves when the application, the amount should be less, 4 ~ 5 kg per mu of urea.

Watering water: after the pulling to the period of pregnancy, to keep the field moisture appropriate.

Remedy after freezing: recovery fertilizer should be applied after freezing, mainly fast-acting nitrogen fertilizer, the amount of fertilizer depends on the size of the group and the degree of frost damage.

Prevention of diseases and insects: pay attention to the prevention and control of blight, powdery mildew and wheat aphids, red spiders and other pests and diseases.
