摘要: 为了探究带宽和大豆密度配置对大豆产量的影响,以玉米-大豆间作模式为研究对象,采用二因素裂区设计,主因素为3个带宽水平(BW1:2.0 m、BW2:2.2 m、BW3:2.4 m),副因素为4个大豆种植密度(D1:52 500株/hm2、D2:67 500株/hm2、D3:82 500株/hm2、D4:97 500株/hm2),调查不同田间配置下的大豆光合特性、干物质积累、器官分配比率、籽粒灌浆及产量。结果表明:带宽增加有利于大豆光合特性、群体干物质积累、籽粒灌浆、百粒质量、单株粒数和产量的增加,BW3的大豆产量较BW1和BW2显著提高了37.2%和19.6%。各密度水平下,大豆产量呈现出先增后减的趋势,D3的大豆产量较D1和D4显著提高了9.4%和6.0%。在BW3下不同密度处理间的大豆产量表现为:D2 > D3 > D4 > D1。在玉米-大豆间作中,带宽2.4 m,大豆种植密度在67 500~82 500株/hm2时,大豆光合特性改善,群体干物质积累量增加,大豆产量较高。

Abstract: In order to explore the effects of bandwidth and soybean planting density on soybean yield in maize-soybean intercropping system.The study used two factors split plot design,the main factors for three levels of bandwidth(BW1:2.0 m,BW2:2.2 m,BW3:2.4 m),deputy factors for four soybean density gradient(D1:52 500 plants/ha,D2:67 500 plants/ha,D3:82 500 plants/ha,D4:97 500 plants/ha),the photosynthesis and dry matter accumulation,organ allocation ratio,grain-filling and yield of soybean were surveyed.The results showed that the increase of bandwidth was conducive to the increase of soybean photosynthetic characteristics,dry matter accumulation of population,grain filling,100-grain weight and grain number per plant,thus increasing soybean yield. The soybean yield of BW3 was significantly increased by 37.2% and 19.6% compared with that of BW1 and BW2. At each density level,the soybean yield showed a trend of increasing first and then decreasing,and the soybean yield of D3 was significantly increased by 9.4% and 6.0% compared with that of D1 and D4. In the case of BW3,the treatment of different densities was as follows: D2 > D3 > D4 > D1. In maize and soybean intercropping,when the bandwidth was 2.4 m and the planting density was 67 500 plants/ha to 82 500 plants/ha,the photosynthetic characteristics of soybean improved and the dry matter accumulation of the population increased,thus increasing the yield.
