摘要:

为提前和延长蚕豆采摘期,增加鲜食蚕豆种植效益,开展蚕豆春化处理时间及种植密度试验。结果表明,蚕豆4 ℃下春化达20~30 d,可以显著提早蚕豆采摘期,拉长采摘周期,显著提高每株豆荚数和百荚重,从而提高鲜荚单位面积产量。春化处理30 d,可显著增加每荚粒数、荚长,降低始花节位。降低种植密度可以增加单株豆荚数、单株分枝数,未对单位面积产量造成显著影响。667 m2种植1 500株(株距35 cm)是最佳的选择,在不减产的情况下,可以节省用种量,降低生产成本和用工,同时又能提高鲜食蚕豆品质。本次试验可为温岭市蚕豆生产提供技术支撑。

Abstract:

In order to advance the picking period, extend the picking cycle of broad beans, and increase the planting efficiency of fresh broad beans, the vernalization treatment time and planting density experiments of broad beans were carried out. The results showed that vernalization of broad bean at 4 ℃ for 20-30 days could significantly advance the picking period of broad bean, extend the picking cycle, significantly increase the number of pods per plant and 100 pod weight, and thus increase the yield of fresh pods. Vernalization treatment for 30 days could significantly increase the number of grains per pod and pod length, and reduce the node position of the first flower. Reducing the planting density could increase the number of pods and branches per plant, but did not have a significant effect on yield. Planting 1 500 plants (plant spacing 35 cm) at 667 m2 is the best choice, which can save the amount of seeds, reduce production costs and labor without reducing yield, and improve the quality of fresh broad beans. This test can provide technical support for the production of broad beans in Wenling City.
