摘    要:通过田间试验, 以大豆单作为对照,设置登海605/贡选1号(RI1)、川单418/贡选1号(RI2)、雅玉13/贡选1号(RI3)3种玉米 大豆带状套作种植模式,研究了玉米株型对大豆干物质积累和产量的影响.结果表明: RI2和RI3处理大豆的积累速率低于RI1处理,且RI1处理大豆叶片、茎秆和荚果的干物质积累量分别比RI2和RI3处理高17.6%、16.5%、13.7%和34.6%、33.1%、28.4%.带状套作大豆叶片、茎秆的分配比例均以RI1处理最高、RI2处理其次、RI3处理最低,而荚果分配比例的变化趋势与其相反.与RI2和RI3处理相比,RI1处理显著提高了大豆营养器官(叶+茎)干物质向荚果的转运量、转移率及其对荚果的贡献率,RI1处理大豆的单株荚数、单株粒数、每荚粒数、单株粒质量和产量分别比RI2和RI3处理提高了6.8%、11.5%、4.4%、15.9%、15.6%和14.3%、22.2%、6.7%、33.4%、36.8%.带状套作大豆营养器官干物质的积累速率、转运量、转移率和贡献率与产量及产量的构成呈显著正相关,且均以RI1处理最高,实现了紧凑型玉米对带状套作大豆干物质积累、转运和分配的有效调控,促进了产量的提高.

Abstract:In order to explore the effects of maize plant types on dry matter accumulation and yield of soybean, a field experiment was conducted in 2013, including three maize soybean relay strip intercropping systems. The relay strip intercropping systems were designed as soybean (Gongxuan 1) intercropped with Denghai 605 (RI1), Chuandan 418 (RI2) or Yayu 13 (RI3), and the mono cultured soybean was used as control. The results demonstrated that the dry matter accumulation rates of intercropped soybean in RI2 and RI3 treatments were lower than in RI1 treatment, and the leaf, stem and pod dry matter accumulation of intercropped soybean in RI1 treatment was 17.6%, 16.5% and 13.7% higher than that in RI2 treatment, and 34.6%, 33.1% and 28.4% higher than that in RI3 treatment, respectively. The distribution proportion of leaf and stem of intercropped soybean was in the order of RI1 > RI2 > RI3. However, the trend of the distribution proportion of pod was opposite. Compared with RI2 and RI3, the dry matter translocation amount, translocation proportion, contribution proportion of soybean vegetative organs to pod of soybean were improved in RI1 treatment, and the pod per plant, seeds per plant, seeds per pod, yield per plant and yield of soybean in RI1 were higher than RI2 and RI3 by 6.8%, 11.5%, 4.4%, 15.9%, 15.6% and 14.3%, 22.2%, 6.7%, 33.4%, 36.8%, respectively. The results showed that the yield was positively rela ted with the accumulation rate of dry matter, dry matter translocation, dry matter translocation ratio and the contribution of dry matter accumulation, and these indices were highest in RI1 treatment. The results indicated that the compact maize relay intercropped with soybean could effectively regulate the dry matter accumulation, translocation and distribution, and improve the yield of soybean.
Keywords:maize plant type   soybean   dry matter accumulation   yield.
