How should fertilization be managed in spring after wheat suffers from snow and ice
The winter snowfall has advantages and disadvantages for wheat, and it should be categorized according to local conditions. For wheat fields that are still alive, they should apply urea 7.5 to 10 kilograms in the returning green period. The wheat fields that are deficient in phosphorus can also be treated with appropriate amounts of diammonium phosphate or superphosphate; wheat fields with better spring moisture can be used for fertilization. In the absence of water, fertilizer can be applied with water, and 10 kg of urea can be applied during the jointing period; for the less severe freezing damage, most of the wheat stems with the main stem and the big locust survive, the cultivator should be strengthened in the early spring, and the heat preservation should be carried out for normal management. The sowing date is shorter than that of the wheat field which is late in the year and the group is insufficient. Do not rush to water in the early spring. Raise the soil temperature and protect the soil by cultivating loose soil.
