种间互作的生态效应Ⅰ.间作对蚕豆结瘤的影响
Ecological effects of interspecific interaction I.Effects of intercropping on nodulation in faba beans
摘要
Abstract
[Objective]The present study was carried out to investigate the effects of intercropping on nodulation in faba bean in different soil types to screen suitable crop and model for intercropping with faba bean. [ Method ]Three kinds of crops, viz., wheat, rape and garlic were used to intercrop with faba beans and monocropping of faba beans was studied in clay and sandy loam soils, respectively. The nodules of faba bean in different intercrops were collected from root rhizosphere of faba bean during pod stage. [Result]The nodule weight of faba bean cultivated with different intercrops in sandy loam soil was higher than that in clay soil. In clay soil, the nodule weight of faba beans in middle line of monocropping, wheat/faba bean and rape/faba bean intercropping significantly increased by 24.54, 97.24 and 61.94% compared to that in edge line, while that in edge line in garlic/faba bean intercropping was 80.06% higher than in middle line. In sandy loam soil, the nodule weight of faba bean in edge line of monocropping, wheat/faba bean, rape/faba bean and garlic/faba bean increased by 8.14, 54.00, 20.45 and 45.33% compared to that of middle line. As compared to monocropping, the nodule weight of faba bean in middle line of rape/faba bean, wheat/faba bean and garlic/faba bean in clay soil significantly increased by 491.13, 75.86 and 70.44%, respectively, and that of edge line increased by 354.60, 11.04 and 282.21%, respectively. In sandy loam soil, except for wheat/faba bean mode, the nodule weight of faba bean in middle line of rape/ faba bean and garlic/faba bean modes increased by 30.69 and 76.41% as compared to monocropping, and that of edge line in wheat, rape and garlic intercropping modes increased by 37.64, 45.56 and 137.07%, respectively. In clay and sandy loam soils, faba bean intercropping with rape and garlic increased nodulation level with 61.94 and 80.05%, respectively. [Conclusion]It was indicated that not only crop species, but also soil condition and planting mode in intercropping influenced nodulation ability of faba bean.关键词
