Field fertilizer efficiency test of wheat quota application of slow-release fertilizer
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.
