减施氮肥对豫南地区弱筋小麦产量与品质的影响
Effects of Reducing Nitrogen Fertilizer Application on Yield and Quality of Weak Gluten Wheat in Southern Henan Province
摘要
Abstract
The study took Yangmai 13 as the test material to explore the effects of nitrogen reduction on yield and quality of weak gluten wheat.A field experiment was set up with six treatments:no nitrogen application(CK1),conventional application of common urea(CK2),conventional application of controlled-release urea(T1),10%controlled-release urea reduction(T2),15%reduction(T3)and 20%reduction(T4).The differences in wheat yield,dry matter accumulation,grain quality and flour characteristics among all treatments were analyzed.The results showed that the grain yield of T1 was the highest,followed by T2,and was significantly higher than that of CK2.Plant height,spike length,grain number per spike and 1000-grain weight of nitrogen-applied treatments were significantly higher than those of CK1,with no significant differences among nitrogen treatments.The 1000-grain weight and spikes per unit area of T1 and T2 treatments were both higher than those in other treatments,while there was no significant difference between T2 and T1.Dry matter mainly accumulated in stems at heading stage and in spikes at maturity stage.In T2 treatment,grain protein content(11.54%),sedimentation value(29.59 mL)and test weight(807.40 g/L)were significantly higher than those of CK1,and showed no significant difference compared with CK2.The softening degree(91.00 BU)of T2 was significantly lower than that of CK1,while its extensibility(177.41 mm)and wet gluten content(21.70%)were significantly higher than those of CK1,with no significant difference from CK2.Dough development time(1.80 min)and stability time(2.22 min)of T2 were significantly lower than those of T1.In conclusion,reducing controlled-release urea application by 10%can stabilize yield and maintain grain quality of weak gluten wheat in southern Henan,which provides a feasible technical scheme for green and efficient wheat production.关键词
