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。
In order to investigate the effects of different cultivation conditions on frostbite and yield of broad bean in the facility, the study was conducted in three groups of randomized block trials with different shelf-life, sowing date and planting density. The results showed as follows: 1 With the delay of filming time, slight frost damage and the number of headless seedlings increased correspondingly, that is, frost damage gradually increased but the yield increased; with the sowing date delayed, the number of branches per plant and effective branches decreased , Mild frostbite and frostbite without head seedling alleviated, that is, frost damage gradually reduced, and the sowing date was the highest on September 30; the density had no effect on frost damage, and the yield increased with the increasing of density. 2 The same film time, with the delay of sowing date, the frost damage gradually reduced, the sowing date to Sept. 30 was higher, the density had no effect on frost damage, and the yield increased with the increase of density; same sowing date, With the delay of time, frost damage gradually increased, yield increased, density had no effect on frost damage, and the yield increased with the increase of density. With the delaying of filming time, the frost damage gradually increased but the yield increased with the sowing time Postponed, frost damage gradually reduced, the production of sowing on Sept. 30 higher. 3 In the same filming time, the same sowing date with the increase of the density of the total number of branches and effective branches decreased relative to increase production; the same frame-film time, the same density with the sowing date delayed freezing injury gradually reduced, and yield Sept. 30 sowing date higher; in the same sowing date, the same density with the delay of filming time gradually increased the frost damage, increased production.
