中文摘要	为了解豫西半干旱区不同水、肥条件对小麦淀粉品质的调控效应,于20092010年度和20102011年度在河南省洛阳市农业科学研究院以"洛旱2号"小麦为材料,采用防雨棚池栽种植方式,研究了不同灌水量、施氮量和施磷量及其互作对小麦淀粉糊化特性的影响。结果表明:施氮量和施磷量对小麦淀粉糊化特性均有显著影响(P≤0.05或P≤0.01);随施氮量的增加,淀粉各黏度参数呈增大趋势,施氮量为105 kg·hm~(-2)时达最大值,之后增加施氮量各黏度参数又有所下降;黏度参数在施磷量为168 kg·hm~(-2)时达最大值。在豫西半干旱生态条件下,灌水量对淀粉黏度参数影响不显著,但存在灌水量*施氮量的显著互作效应(P≤0.05或P≤0.01)。从不同水肥处理组合看,淀粉糊化特性以处理组合N_(105)P_(168)W_(217.5)[施氮量105 kg(N)·hm~(-2)、施磷量168kg(P_2O_5)·hm~(-2)和全生育期灌水量217.5 mm]最优。相关分析表明,淀粉黏度参数与籽粒产量在20092010年度呈显著正相关,而在20102011年度相关不显著,说明产量与淀粉品质间存在着协同提高的可能性。
英文摘要	A field experiment was conducted under rain-shelter conditions in Luoyang(Henan Province) during the 2009-2010 and 2010-2011 cropping seasons by using "Luohan 2" winter wheat cultivar.The objective of the experiment was to evaluate the effects of irrigation and nitrogen/phosphorus fertilization on grain quality of winter wheat in the semiarid region of West Henan Province.The experiment was a factorial combination of 5 irrigation,nitrogen and phosphorus application rates,each in 3 replicas.The effects of water,nitrogen and phosphorus application rates and interactions on starch paste parameters of winter wheat were determined.The results showed that the application of nitrogen and phosphorus fertilizers had significant effects on starch paste properties of winter wheat(P≤0.05 or P≤0.01).Main starch viscosity parameters(peak viscosity,initial viscosity and final viscosity) increased sig-nificantly as nitrogen application increased from 0 kg·hm~(-2) to 105 kg·hm~(-2),and after peaking at 105 kg·hm~(-2) decreased with nitrogen application rate.Starch viscosity parameters reached the highest values at phosphorus application rate of 168 kg·hm~(-2).Irrigation had no significant effect on starch paste properties.However,irrigation and nitrogen interactions significantly influenced some starch paste properties.Overall,combined treatments of nitrogen,phosphorus and water at N_(105)P_(168)W_(217.5)-i.e.,105 kg(N)·hm~(-2),168 kg(P_2O_5)·hm~(-2) and 217.5 mm irrigation-produced the best starch quality.Statistical analysis indicated a significant positive correlation between starch paste properties and grain yield in the 2009-2010 cropping season and not in the 2010-2011 crop season.This suggested that there existed the possibility for improvement of both grain yield and starch paste quality in the region.
