In winter and early spring when the temperature is low, the wheat field pest management, fertilization should pay attention to the following two points: Insect pest control wheat aphids, red spiders and other pests, spraying omethoate better than dimethoate. Because the detoxification efficacy of dimethoate on insect pests decreases significantly with decreasing temperature, the efficacy of omethoate is less affected by temperature, and normal insecticidal effects can be exerted below 15°C. Similar to omethoate, cypermethrin is also more effective at 15°C than at 25°C. Fertilizer topdressing Ammonium bicarbonate is better than urea. Ammonium bicarbonate can be directly absorbed and utilized by wheat after it is applied to the soil, while urea needs to be converted into ammonium carbonate by urinary bacterial enzymes in the soil for root absorption. The rate of urea conversion mainly depends on the soil temperature at that time; under normal circumstances, all the urea applied to the soil is converted to ammonium carbonate, which takes 7 to 10 days at a ground temperature of 10°C. Visible, wheat in the winter or early spring top dressing, ammonium bicarbonate effect faster than urea. If urea is used, the growth of the wheat seedlings will be affected by the slowness of the fertilizer effect.
