中文摘要	基于黄土高原干旱地区生态环境特性,研究了4种糜子(P)-绿豆(M)间作模式下[2∶ 2(2P2M)、4∶ 2(4P2M)、4∶ 4(4P4M)、2∶ 4(2P4M)]农田小气候特征及产量效应.结果表明:糜子-绿豆间作模式显著增加了生育后期糜子的株高、叶面积指数(LAI)和叶绿素含量(SPAD),使其达到最佳的生长状态;由于高位糜子的遮阴,导致矮位绿豆阶段性徒长,株高显著增加,而LAI和SPAD均有所下降.糜子-绿豆间作模式降低了糜子籽粒灌浆过程中的群体上层光照度和空气温度,而相对湿度显著上升.地上部气候环境的变化调控了间作体系地下部的土壤温度,减少了群体的漏光损失,使其表现出冷湿的生态环境.而矮位绿豆较差的通风透光条件形成相对封闭的间作系统,抑制了绿豆植株的生长发育,使其处于间作劣势.与单作相比,2P2M、4P2M、4P4M和2P4M处理的糜子单株穗数、穗长、单株粒重和千粒重分别增加了7.5%~45.0%、2.2%~12.2%、35.4%~94.0%和2.3%~4.7%,产量比单作提高了5.6%~ 20.7%;间作处理下矮位绿豆的分枝数、单株荚数、单株粒重和百粒重均有不同程度的下降,2P4M间作模式下的绿豆受糜子影响最小,产量比单作降低了34.8%.糜子-绿豆间作存在明显的间作优势,各间作处理下的土地当量比(LER)均大于1,2P4M间作模式下的LER达到最大值(1.86).因此,黄土高原地区糜子-绿豆最佳的间作配比为2P4M.
英文摘要	Based on the ecological environment features of Loess Plateau,we examined field microclimate characteristics and yield of four different intercropping patterns for proso millet (P) and mung bean (M) including 2: 2,4: 2,4: 4,2: 4. The results showed that,compared with monoculture, intercropping increased plant height,leaf area index (LAI) and chlorophyll content (SPAD) of proso millet in its late growth stage,while LAI and SPAD of mung bean decreased due to the shade of the high proso millet. Mung bean appeared spindly growth for a while by increasing the plant height. Moreover,upper canopy illumination and air temperature during grain filling stage of proso millet decreased under intercropping conditions,but relative humidity substantially increased. These changes regulated soil temperature and light leakage,which decreased under intercropping systems,and thereby led to a cold and wet ecological environment. Poor atmospheric and light conditions formed a relative closure growth environment for mung bean,which suppressed its growth. The panicles,spike length,grain mass per plant and 1000-grain mass of proso millet under 2P2M, 4P2M,4P4M and 2P4M treatments was significantly increased by 7.5%-45.0%,2.2%-12.2%, 35.4%-94.0% and 2.3%-4.7%,respectively. This caused a 5.6%-20.7% increase of yield than the mono-culture. The branch number,pods per plant,grain mass per plant and 100-grain mass in mung bean were decreased under different intercropping treatments,and the yield was significantly reduced by 34.8%. Land equivalent ratios (LER) of each intercropping pattern were all greater than 1. Among them,LER of 2P4M was the maximum (1.86),and 2P4M treatment held relatively reasonable composite configuration. Our results suggested that 2: 4 ratio of proso millet /mung bean intercropping patterns performed better than other ratios on the Loess Plateau.
