Abstract:

【Objective】 To clarify the effects of sowing dates and fertilizer types on the occurrence dynamics of Sitobion avenae in the field, so as to provide technical support for the rational use of pesticides and scientific control of wheat aphids.【Method】 Random block design and regular and fixed-point investigation were conducted to record the number of Sitobion avenae in the occurrence period of Sitobion avenae.【Result】 Different sowing dates and survey time had significant effects on the AP values.The AP values of the late sowing treatments from May 19 to June 8 were 3.40, 5.82, 5.44, 2.32 and 0.00, respectively, which were significantly lower than those of the regular sowing treatments.Different fertilizer application treatments and survey time both had significant effects on the AP values.The AP values of the treatment of organic fertilizer replacing nitrogen fertilizer by 60%, 40% and 20% in late sowing fields were 4.83, 4.70 and 4.11 respectively, which were significantly higher than those of the treatment of inorganic fertilizer treatment in late sowing fields.【Conclusion】 Compared with the regular sowing treatment, the late sowing treatment can significantly reduce the populations of S.avenae.Organic fertilizer replacing nitrogen fertilizer is benefit to feed S.avenae, and the higher the proportion of nitrogen fertilizer replaced, the bigger the population of the wheat aphid would be.

摘要:

【目的】研究晚播和有机肥替代氮肥对麦长管蚜种群动态的影响,为合理使用农药及科学防控麦长管蚜提供技术支持。【方法】采用随机区组设计和定期、定点调查的方法记录麦长管蚜发生期的虫口数量。【结果】不同播期和调查时间均对AP值有显著影响,5月19日至6月8日晚播处理麦长管蚜的AP值分别为3.40、5.82、5.44、2.32和0.00,均显著低于正常播期处理。不同肥料处理和调查时间对AP值有显著影响,晚播小麦有机肥替代氮肥60%、40%和20%处理麦长管蚜的AP值分别为4.83、4.70和4.11,均显著高于晚播无替代处理。【结论】与正常播期相比,小麦晚播可显著降低麦长管蚜的种群数量。有机肥替代氮肥有利于麦长管蚜取食为害,且有机肥替代氮肥比例越高,麦长管蚜发生越重。
