摘要:
2011~2012年,以当地主推的中粒型品种海门大青皮、小粒型品种启豆2号和自主育成具有知识产权的鲜食蚕豆品种通鲜1号、通鲜2号、通鲜3号、通蚕鲜6号4个大粒型蚕豆品种为供试材料,进行品种和打顶处理的裂区试验,研究打顶对其产量及构成因素的影响。结果表明不同品种的株高不存在显著差异,鲜荚产量、生物产量、收获指数等产量相关性状有差异,通鲜1号、通鲜2号、通鲜3号以及通蚕鲜6号这4个育成品种的产量表现明显高于海门大青皮和启豆2号,在单荚鲜重方面也具有明显的优势。打顶处理有效地降低了蚕豆株高和生物产量,提高了鲜荚产量以及收获指数,表明打顶可以使设施蚕豆获得更好的生态效益以及经济效益。

Abstract:
With a split-plot design,in 2011-2012,various factors were selected for the control plot,as well as the subplots,to study their effects relating to the yield of 6 broad bean varieties(i.e.,the medium grain Haimendaqingpi,the small grain Qidou 2 and the big grain Tongxian 1,2 and 3,and Tongcanxian 6).The preliminary results showed no significant differences on plant height among different varieties.However,the yield,biomass and harvest index were significantly different.The yield and weight per pod of the varieties bred by the Institute,such as Tongxian 1,2,3 and Tongcanxian 6,were significantly higher than local varieties.The topping on the winterizing facility decreased the plant height and biomass,while increased the yield and harvest index.It suggested that the broad bean cultivation benefited ecologically as well as economically by adding a topping to the winterizing shed
