Abstract:

In order to simplify wheat fertilization, slow-release fertilizers were selected to carry out field fertilizer efficiency experiments in line with wheat quota fertilization standards. The results showed that when the nitrogen was reduced by 20% and the total nutrient input was reduced by 10%-13%, the yield of wheat increased by 9.5%-17.0%, which was mainly achieved by increasing the number of grains per panicle by 1.0-1.7, or increasing the effective panicle number per unit area and 1 000-grain weight.

Key words: wheat, slow-release fertilizer, emergence rate, yield
