Effects of wheat special fertilizers combined with modifier on yield,quality,and fertilizer and water efficiency of wheat in dry land
The study focused on providing a basis for rational fertilization of the effects of special wheat fertilizer combined with improver on yield,root development,quality,nutrient,and fertilizer and water utilization of strong gluten wheat in dry land.In 2021-2023,the effects of no nitrogen application(CK),conventional nitrogen application rate(FP),wheat special fertilizer,and modified agent(T1,T2,T3)on wheat yield,root system,quality,nutrient,fertilizer and water efficiency of dryland wheat were studied.The results showed that compared with those of FP treatment,the grain yield and its component factors of special wheat fertilizer combined with modifier(T2 and T3)increased by 5.89%and 11.53%,aboveground biomass increased by 3.67%and 4.26%,protein content,wet gluten content,and grain nutrients were increased respectively.Compared with those of FP treatment,the agronomic efficiency of nitrogen fertilizer of T2 and T3 increased by 43.42%and 70.55%,fertilizer productivity increased by 5.93%and 7.77%,the nitrogen utilization rate increased by 10.78 and 27.73 percentage points,and economic benefits increased by 5.13%and 12.01%respectively.Under the T2 treatment mode,the flour's rheological properties were the best.N∶P2O5∶K2O ratio of 21∶18∶5 wheat fertilizer combined with straw maturing agent and water retaining agent could improve fertilizer utilization and wheat yield efficiency in dry land.
