单间作种植模式对色素万寿菊农艺性状及产量的影响

Effects of Monocropping and Intercropping Patterns on Agronomic Traits and Yield of Pigment Marigold

以色素万寿菊为试材,研究单作模式以及与不同树龄巴旦木、核桃间作模式对其冠层微气候、农艺性状、产量的影响,评估不同种植模式的生产效益。结果表明:单作模式下色素万寿菊冠层光照强度最高,随间作树种树龄自9年生增至15年生,巴旦木间作模式下色素万寿菊冠层光照强度由9500.00~10830.00 lx降至1676.67~2140.00 lx,核桃间作模式下色素万寿菊冠层光照强度由8733.33~10336.67 lx降至773.33~1480.00 lx,温湿度则无规律性变化。各处理中单作模式色素万寿菊冠幅最小,茎粗最细,二级分枝数最多,叶黄素含量最高,但鲜花产量以15年生核桃间作色素万寿菊模式最高。7种种植模式中以15年生巴旦木间作色素万寿菊模式经济效益最高,生产中可进行推广应用。

Taking pigment marigold as the test material,the effects of monocropping and intercropping patterns with almond and walnut of different tree ages on canopy microclimate,agronomic traits and yield of pigment marigold were studied,and the economic benefits of different planting patterns were assessed.The results showed that in 7 planting patterns the highest light intensity of pigment marigold canopy was in monocropping pattern.With intercropping tree age increasing from 9 to 15 years,the light intensity of pigment marigold canopy decreased from 9500.00-10830.00 lx to 1676.67-2140.00 lx in almond intercropping pattern,and the light intensity of pigment marigold canopy decreased from 8733.33-10336.67 lx to 773.33-1480.00 lx in walnut intercropping pattern.There are no regular changes in temperature and humidity.Monoculture pigment marigold had the the smallest crown breadth,the slimmest stem,the largest number of secondary branches,and the highest lutein content in 7planting patterns,but the highest flower yield belonged to the 15-year-old walnut intercropping pigment marigold.The economic benefit of 15-year-old almond intercropping pigment marigold was the highest,and this planting pattern can be popularized in production.
