摘要: 通过对小麦田主要杂草藜、野燕麦不同密度对小麦产量构成因素的影响,及防治中生态经济阈值模型的初步研究,建立了藜、野燕麦不同密度与小麦有效穗数、小穗数、穗粒数、千粒重和小麦产量损失率间的函数关系式,明确了藜、野燕麦不同密度对构成小麦产量各因素影响作用,制定出适合当地杂草藜和野燕麦的生态经济阈值,即田间藜密度达到1.45~1.83株/m2时,野燕麦密度达7.15~8.60株/m2时,分别使用72% 2,4-D丁酯乳油和10%骠马乳油进行化学防治。

Abstract: The function equations between the different density of Chenopodium album L. , Avena fatua L. and wheat spica, spikelet, spica gains, thousand kernel weight and yield reduction rate were established by studying the effect of Chenopodium album L. , Avena fatua L. density on wheat yield factors, and their eco-economic threshold model. The result showed Chenopodium album L. and Avena fatua L. should be controled using 72% 2, 4-D butylate and 10% Puma super when their density in field were up to 1.45-1.83 plants/m2, 7.15-8.60 plants/m2 respectively.

Key words: Wheat-field, Chenopodium album L., Avena fatua L., Eco-economic threshold, Control index
