In the winter and early spring when the temperature is low, the following two points should be noted in the treatment of insects and fertilization in wheat fields:
Insect control of wheat aphids, red spiders and other pests, spraying omethoate is better than dimethoate. Because the poisoning effect of dimethoate on pests is significantly reduced with the decrease of temperature, the efficacy of omethoate is less affected by temperature, and it can exert normal insecticidal action at temperatures below 15 °C. Similar to omethoate, there is also pyrethroid, which is more toxic at 15 ° C than at 25 ° C.
Fertilization and topdressing application of ammonium bicarbonate is better than urea. Ammonium bicarbonate can be directly absorbed and utilized by wheat after being applied to the soil, and urea needs to be converted into ammonium carbonate by the action of urinary bacterial enzymes in the soil for root absorption. The rate of urea conversion depends mainly on the soil temperature at that time; under normal conditions, all of the urea applied to the soil is converted to ammonium carbonate, which takes 7 to 10 days at a ground temperature of 10 °C. It can be seen that wheat is topdressed in winter or early spring, and the application of ammonium hydrogencarbonate is faster than urea. If urea is applied, it tends to affect the growth of wheat seedlings because of the slow effect of fertilizer.
