毛叶苕子与不同作物混播、间作对种子生产的影响

Effects of mixed sowing and intercropping of Vicia villosa Roth with different crops on seeds

为了提高毛叶苕子的种子产量,本文通过毛叶苕子单播、燕麦和毛叶苕子混播、燕麦和毛叶苕子间作、小麦和毛叶苕子混播、小麦和毛叶苕子间作、油菜和毛叶苕子混播、油菜和毛叶苕子间作等7个种植模式,研究不同种植模式对毛叶苕子种子产量及土壤理化性质的影响。结果表明:小麦与毛叶苕子间作处理与毛叶苕子单播处理相比显著提高了毛叶苕子产量(54.44%);与毛叶苕子单播处理相比,油菜与毛叶苕子混播处理显著提高了土壤中有机质含量(15.50%)、速效钾含量(40.93%)。本研究结果可为青海地区毛叶苕子繁种提供理论依据。

In order to improve the seed yield of Vicia villosa Roth,the optimal combination of Vicia villosa Roth with different crops together with the effects of mixed sowing and intercropping on its seed yield and soil physicochemical properties is studied by adopting seven planting modes,namely single sowing of Vicia villosa Roth,mixed sowing of oat and Vicia villosa Roth,intercropping of oat and Vicia villosa Roth,mixed sowing of wheat and Vicia villosa Roth,intercropping of wheat and Vicia villosa Roth,mixed sowing of rape and Vicia villosa Roth,intercropping of rape and Vicia villosa Roth.The results show that compared with single sowing of Vicia villosa Roth,intercropping wheat with Vicia villosa Roth significantly increases the yield of Vicia villosa Roth(54.44%).Compared with single sowing of Vicia villosa Roth,mixed sowing of rape and Vicia villosa Roth significantly increases the content of organic matter(15.50%)and the content of available potassium in soil(40.93%).The results can provide a theoretical basis for the propagation of Vicia villosa Roth in Qinghai.
