摘　　要：以谷子品种长生07和大豆品种中黄30为材料,分析了不同谷子间作大豆模式对谷子、大豆植株不同叶层受光条件和植株生长的影响,并分析了间作模式对谷子和大豆光合产物积累、分配的影响。结果表明,不同间作模式促进了谷子干物质积累,提高了穗长和单穗重,有利于谷子形成大穗,由于谷子的遮蔽作用,降低了大豆干物质积累、单株有效荚数和百粒重。4种间作模式处理总产量均高于单作大豆处理,其中间作模式M_(3)S_(3)处理总产量与单作谷子产量差异较小,M_(3)S_(3)处理(谷子3行大豆3行,谷子行距25 cm,株距10 cm,大豆行距40 cm,株距14 cm)是较适宜的栽培方式。Using millet variety Changsheng 07 and soybean variety Zhonghuang 30 as materials,the effects of different millet inter⁃cropping soybean models on the light exposure in different leaf layers and platnt growth of millet and soybean under different intercrop⁃ping pattern were analyzed,and the effects of intercropping patterns on the accumulation and distribution of photosynthetic products in millet and soybean were analyzed.The results showed that different intercropping patterns promoted the dry matter accumulation of mil⁃let,increased spike length and single spike weight,and facilitated the formation of large spikes in millet.Due to the shading effect of millet,dry matter accumulation,effective pod number per plant and 100-seed weight of soybean were reduced.The total yield of the four intercropping modes was higher than that of the single cropping soybean,and the difference between the total yield of the inter⁃cropping mode M_(3)S_(3) and that of the single cropping millet was small.M_(3)S_(3) treatment(Planting 3 rows of millet and 3 rows of soybean,the row spacing of millet is 25 cm,the plant space of millet is 10 cm,the row space of soyben is 40 cm,the plant space of millet is 14 cm)is a suitable cultivation method.
