鲜食蚕豆'陵西一寸'低温春化处理时长探索
Explore of Duration of Low Temperature Vernalization of Fresh Broad Bean'Lingxiyicun'
摘要
Abstract
[Objective]Effect of duration of low temperature vernalization on main characters and yield of fresh pod was explored to enhance stable development of characteristic industry of fresh broad bean in winter.[Method]Fresh broad bean'Lingxiyicun'was used as material and duration of low temperature vernalization for 0 d(control),5 d,10 d,15 d,20 d,25 d and 30 d were set on germinated broad bean at(4±1)℃.Effects of duration of low temperature vernalization of main characters and yield of fresh pod of fresh broad bean were compared.[Result]With increase of duration of low temperature vertalization,first flower and harvest time were in advance,first flower node was lowered,branching number per plant was decreased while pod number and fresh pod weight per plant and fresh pod weight per 667 m2 showed firstly upward and then downward trend.Vernalization for 25 d could result in the highest yield of fresh pod and for 20 d the second yield,which was very significantly higher than that for control by 23.7%and 18.9%,respectively.Fresh pod could be harvested earlier by 9-16 d.Through analysis of effectiveness function model,yield of fresh pod was the highest when vernalizated for 23.46 d.[Conclusion]Germinated broad bean'Lingxiyicun'was vernalized for 20-25 d at(4±1)℃and then were sowed,which could be harvested in advance to realize increased yield and income.关键词
