| 摘要：为研究紫豇豆品种绵紫豇1号的配套栽培技术，为其栽培及推广提供科学依据，进行了6个播种期及3个种植密度的双因子试验，分析不同播种期与密度对绵紫豇1号的生育期、植物学性状和产量的影响。结果表明：对绵紫豇1号豇豆产量的影响顺序依次为播种期＞播种期与密度互作＞密度；产量随播种期的推迟呈下降的趋势，随密度的增大呈先升后降趋势。综合得出，绵紫豇1号在四川地区的适宜播种期为3月25日前后，播种期不宜太迟，太迟会影响产量；在土壤中上等肥力水平下的适宜种植密度为667 m2栽8 100株。 |

| Abstract: In order to study the supporting cultivation technology of purple cowpea cultivar 'Mianzijiang No.1' and provide scientific basis for its cultivation and promotion, double factors experiments of six sowing
dates and three planting densities were conducted to analyze the effect of different sowing dates and densities on the growth period, botanical characters and yield of 'Mianzijiang No.1'. The results showed that the effect order of yield of 'Mianzijiang No.1' was sowing date > sowing date and density interaction > density. The yield decreased with the delay of sowing date, and increased first and then decreased with the increase of density. It was concluded that the suitable sowing date of 'Mianzijiang No.1' in Sichuan was around 25 March, and the sowing date should not be too late, otherwise it would affect the yield. The optimum planting density was 8 100 plants per 667 m2 at the medium to high fertility level in the soil. |
