Effects of Different Fertilization Measures on Wheat Growth and Nitrogen Use Efficiency in High Latitude Region
To reveal the effects of different fertilization measures on wheat growth and nitrogen utilization efficiency in high latitude areas.By combining field observation and indoor measurement to study the effects of two slow-release fertilizers and one nitrogen deficiency treatment on the growth and utilization-rate of nitrogen fertilizer in high latitude area.The results showed that the slow-release fertilizer containing humus had the greatest effect on aboveground biomass and yield,increased by 4.93%and 1.77%,respectively.The slow release fertilizer containing hu-mus increased the contribution rate of nitrogen fertilizer and the agronomic efficiency of nitrogen fertilizer,with the amount of 8.71%and 5.48 kg/kg,respectively.The nitrogen deficiency treatment had the largest side effect on the dry biomass of wheat,which was 4.9%lower than the conventional fertilization.The results showed that the slow release fertilizer containing humus could effectively promote the production of wheat and improve the utilization rate of nitrogen fertilizer in high latitude areas.
