蜂蜜模拟麦蚜蜜露危害对小麦产量 和主要营养品质的影响

在孕穗、抽穗扬花、灌浆3个小麦生育期，分别用蜂蜜模拟麦蚜蜜露危害小麦，最后分小区收获、脱粒、室内考种并测定小麦产量和主要营养品质指标。结果表明，随着蜜露危害程度的加重，小麦千粒重、面粉淀粉含量、湿面筋含量、蛋白质含量在小麦3个生育阶段均呈下降趋势。3个生育期分别被害后，小麦籽粒千粒重、蛋白质含量受影响程度最明显，湿面筋含量次之，淀粉含量变化不大。蜜露危害对小麦产量与主要营养品质的影响，在小麦3个生育期之间存在一定差异。

Influence of Honeydew on the Wheat Yield and Nutritive Qualities

Artificial honeydew is used to imitate effect of aphid’s honeydew on the wheat yield and qualities in the three different wheat growth stages including booting stage, earring period and milking stage. The results show that agronomic characteristic, the content of the starch, wet gluten and protein are much lower than those no-damage wheat in the three stages of wheat according to the difference of concentrations of artificial honey-dew. In the booting stage, the maximal lost rate of agronomic characteristic, the content of starch, wet gluten and protein is 30.75%, 9.16%, 13.32% and 34.36%, respectively; In earring period, which is 41.79%, 8.26%, 14.83% and 39.26%. In milking stage, which is 47.21%, 9.26%, 24.01% and 44.63%. And the effects on agronomic characters and content of protein were most serious, on the content of wet gluten was less, while the content of starch was hardly affected. The effects of aphid harmfulness on yield and main nutritive qualities were different in the three different wheat stages.
