蚕豆是一种用地养地的杂粮作物,在我县春粮生产中占有举足轻重的地位。但长期以来,亩产只有100～130％斤,其原因主要是大量落花落荚所致。为了探索防止蚕豆花荚脱落的有效途径,以提高其产量,笔者自1978年秋开始,选用当地农家品种慈溪“大白蚕”及引种的“启豆1号”等五个品种,连续10年进行了系统的调查观察和田间试验,现将结果总结如下。 Broad bean is a land-based coarse grains crops, spring grain production in our county occupies a pivotal position. However, for a long time, the yield per mu is only 100-130 kg, mainly due to the large number of fallen peas. In order to explore an effective way to prevent the fall of broad bean flower pods in order to increase their yield, the author selected five varieties of “Caili” and “Qidou No.1” from Cixi, a local farmhouse variety, for the first ten years in succession Systematic investigation and field trials, the results are summarized below.
