摘要:
以食用毛豆为研究对象,研究环巢湖地区涝渍灾后补种的最迟安全播种时期和最佳补种品种,旨在为指导该地区农民开展灾后补种毛豆生产技术、减轻涝渍灾害对作物产量的影响提供依据。结果表明:(1)8月20日及以前播种毛豆能正常生长、收获。毛豆产量随着播期的推迟,逐渐减少。8月25日及以后播种的毛豆花芽分化期,开花期、结荚期都比前几期延长,株高降低,荚数减少,且不能充分鼓粒,无经济产量。因此,该地区补种毛豆的最迟安全播种期为8月20日。(2)在供试的毛豆品种中,科蔬一号、95-1和理想M-7 3个品种的生育时期短、产量较高、荚粒性状较优、口感评价较好,可作为环巢湖地区涝渍灾后补种毛豆新品种引进和推广。

Abstract:
In this research, the latest reseeding time and suitable varieties of green soy bean after a flood damage in Chaohu areas of Anhui Province were investigated to provide substantial guidelines for post-flood reseeding for farmers, which can alleviate the impacts of flood disaster and provide a guarantee for normal post-disaster operation of crop production in this area. The results showed that the green soy bean sowed on August 20th or before showed normal growth and can be harvested. The yield was decreasing when the sowing time was delaying. The green soy bean sowed on August 25th or after showed abnormal growth and development including a prolonged period of flower and bud differentiation, anthesis, and fruiting. The plant height decreased with fewer pods and poorly-developed seeds compared to the soy bean sowed before August 20th. The latest and safe sowing time for green soy bean in this area was August 20th. Keshu No.1, 95-1 and Lixiang No. M-7 are varieties that can be introduced and promoted for green soy-bean production in the waterlogged disaster region for reseeding due to their short growth period, higher yield, better pod grain traits, and good taste.
Key words:  reseeding after disaster  green soy bean  safe sowing time  varieties
