为探讨不同栽培条件对设施蚕豆冻害以及产量的影响，该研究以鲜食蚕豆品种通鲜2号为材料，进行了不同架膜时间、播期和种植密度三因素随机区组试验。结果表明：①随着架膜时间的推迟，轻度冻害以及无头苗的数量相应增加，即冻害逐渐加重，但产量增加；随着播期的推迟，单株分枝数、有效分枝减少，轻度冻害以及无头苗冻害现象减轻，即冻害逐渐减轻，产量以9月30日的播期最高；密度对冻害无影响，产量随着密度的增加而增加。②同一架膜时间，随着播期的推迟，冻害逐渐减轻，产量以9月30日的播期较高，密度对冻害无影响，产量随密度增加而增加；同一播期，随着架膜时间的推迟，冻害逐渐加重，产量增加，密度对冻害无影响，产量随着密度的增加而增加；同一密度，随着架膜时间的推迟，冻害逐渐加重，但产量增加，随着播期的推迟，冻害逐渐减轻，产量以9月30日的播期较高。③在相同架膜时间、相同播期下随着密度的增加总枝数和有效分枝相对减少，产量增加；在相同架膜时间、相同密度下随着播期的推迟冻害逐渐减轻，而产量以9月30日播期的较高；在相同播期、相同密度下随着架膜时间的推迟冻害逐渐加重，产量增加。

Using Tongxian No.2 as material, the effects of different film-covering time, different sowing time and different planting density on the occurrence of freeze injury and yield of fresh broad beans were investigated. The randomized block de-sign was adopted. The results showed that with the delayed film covering, the inci-dence of mild freeze injury and number of headless seedlings were increased cor-respondingly, but the yield was increased; with the delayed sowing, the branch number per plant, effective branch number per plant, incidence of mild freeze injury and number of headless seedlings were al reduced, and the broad beans, sowed on September 30th, obtained the highest yield; planting density showed on effect on the occurrence of freeze injury, and the yield was increased with the increase of planting density. Under the same film-covering time, the incidence of freeze injury was reduced with the delayed sowing time and it showed no changes when plant-ing density was changed, but the yield was increased with the increase of planting density and it was highest when broad bean seeds were sowed on September 30th;under the same sowing time, the incidence of freeze injury was increased with the delayed film-covering time and it showed no changes when planting density was changed, and the yield was increased with the delayed film-covering time and in-creased planting density; under the same planting density, the incidence of freeze injury was increased with the delayed film-covering time but was reduced with the delayed sowing time, and the yield was increased with the delayed film-covering time and it was highest when the broad bean seeds were sowed on September 30th. Under same film-covering time and sowing time, the total branch number per plant and effective branch number per plant were reduced, but the yield was in-creased with the increase of planting density; under same film-covering time and planting density, the incidence of freeze injury was reduced with the delayed sowing time, and the yield was highest when broad bean seeds were sowed on September 30th; under same sowing time and planting density, the incidence of freeze injury and the yield were al increased with the delayed film-covering time.
