Study of Soil Nutrients and Wheat Yield and Quality Effected by Soil Testing Formula Fertlizer
To explore the effects of different fertilization methods on wheat yield and nutrient use in Yingshan County,Si-chuan,and to promote scientific fertilization;The experiment was conducted with five treatments:no fertilizer(T1),no nitrogen(T2),no phosphorus(T3),no potassium(T4)and no fertilizer(T5),the grain yield of T5 treatment was the highest,which was significantly higher than that of T1 and T2 treatment,the agronomic efficiency of chemical fertilizer,ni-trogen fertilizer,phosphorus fertilizer and potassium fertilizer were 23.78%,22.61%,11.10%and 2.44%,respective-ly,nitrogen,phosphorus and potassium fertilizers increased grain yield and nutrient uptake of wheat significantly,which was more suitable for wheat production in Yingshan County,Sichuan.
