不同间作模式对燕麦产量及其构成因素的影响
Effects of different intercropping patterns on oat yield and its components
摘要
Abstract
[Objective]To clarify the effects of different intercropping patterns on oat yield and its components,with the goal of optimizing intercropping techniques to enhance land productivity and improve the regional ecological environment in the agro-pastoral ecotone of Yanmen Pass.[Methods]A field experiment was conducted in 2022 at the Youyu Base of the Institute of Ecological Agriculture and Animal Husbandry,Shanxi Agricultural University.Three intercropping patterns were established namely oat-soybean(O//S),oat-red kidney bean(O//R),and oat-potato(O//P),using monocropping of each crop as controls.Crop yield and yield components were measured under different planting patterns to identify the optimal intercropping configuration for oats.[Results]All three intercropping patterns exhibited significant intercropping advantages,with land equivalent ratio(LER)exceeding 1,reaching 1.13(O//S),1.16(O//R),and 1.33(O//P).The oat row yield in the border rows was significantly higher than that in the inner rows and monocropping across all three patterns,demonstrating a prominent border effect.Oats showed stronger resource competitive ability than companion crops across all three patterns,with the highest oat competitive index(1.64)observed in the O//P pattern.[Conclusion]The oat-potato intercropping pattern not only ensures stable oat yield but also achieves the highest land-use efficiency,suggesting high value for promotion and application in the agro-pastoral ecotone of Yanmen Pass.关键词
