赖氨酸叶面肥施用对小麦产量和品质的影响
Effects of foliar fertilizer application of lysine on wheat yield and quality
摘要
Abstract
To explore the ways of agricultural resource utilization for large-scale fermentation industry by-products,this study developed a lysine foliar fertilizer using typical amino acid industrial by-products as raw materials.Through field experiments,the effects of different spraying concentrations on wheat yield,quality and physiological characteristics were examined.Using wheat variety Annuo 859 as the test material,five concentrations of lysine foliar treatments were set:CK(spraying the same amount of deionized water),A1(1.25 mL·L-1),A2(1.67 mL·L-1),A3(2.50 mL·L-1)and A4(5.00 mL·L-1).Foliar spraying was carried out during the green-up period and the booting period.At the harvest time,wheat yield and its yield components,quality,biomass and nutrient contents in different parts were measured,and growth indicators,photosynthetic parameters and leaf antioxidant enzyme activities during key growth periods were monitored.The results showed that as the concentration of lysine foliar fertilizer increased,wheat yield,biomass,physiological indicators and nutrient accumulation generally showed a trend of increasing first and then decreasing.Compared with CK,A3 significantly increased the leaf area index of wheat in the middle and late growth stages,and significantly increased the number of spikes per unit area and aboveground biomass by 12.78%and 22.28%,respectively.In terms of nutrients and quality,the A3 treatment promoted the absorption of macronutrients(N,P,K)by plants and the transfer of micronutrients(Zn,Mo,etc.)to reproductive organs,which significantly increased the soluble sugar content by 1.69 percentage points while maintaining the core protein content of grains stable.In terms of physiological regulation,the net photosynthetic rate(Pn),stomatal conductance(Gs),superoxide dismutase(SOD)and ascorbate peroxidase activity(APX)activities in the A3 treatment reached relatively high level,indicating that it could synergistically enhance photosynthetic capacity and antioxidant metabolism.In summary,on the basis of conventional base fertilizer application,spraying 2.50 mL·L-1 of this lysine foliar fertilizer once during the green-up period and the booting period of wheat achieved the best yield and quality improvement effect.Considering the complexity of the attributes of industrial by-products and the field environment,the concentration-effect results established in this study can provide a scientific reference for the promotion and application of similar fermentation by-products in different ecological areas.关键词
