| 摘 要： | 为明确当前耕作制度方式下小麦主要病虫草害发生危害对小麦产量的影响,河北省安新县2014—2016连续3年进行了小麦病虫草害危害自然损失率试验。通过田间试验,基本明确了在当年小麦病虫草害自然发生状态下,小麦主要病虫草害杂草、蚜虫等的综合危害损失率为70%~87%,明确了科学植物保护措施在小麦生产防灾减灾中的贡献程度,为科学评估小麦病虫草害危害损失提供了参考依据。

Wheat Yield Loss Caused by Major Diseases, Pest-insects and Weeds: Experiment on Natural Loss Rate |
| |
| Abstract: | The paper aims to figure out the effects of major diseases, insect pests and weeds of wheat on yield under current farming system. Anxin Plant Protection Station carried out an experiment on the natural loss rate caused by wheat diseases, insect pests and weeds from 2014 to 2016. Through the field experiment, we basically figured out that the loss rate of wheat yield was from 70% to 87% in the case of the natural occurrence of wheat diseases, insect pests (such as aphid) and weeds, and defined the contribution of scientific plant protection measures in wheat production. The experiment provides a reference for evaluating the damage and loss caused by wheat diseases, insect pests and weeds. |
