一,引言关于甘兰(Brasica oleracea L.Var.capitataL.)未熟抽苔植株所获得的种子,一般蔬菜科学工作者和菜农都認为没有采种价值。因此,发現这样的植株,全部弃而不用。經过我們三年的試种观察,認为把未熟抽苔的种子,作为春季的生产种子,不但与一般采种方法能获得坚实的叶球和正常的生产外,而且还有提早成熟增加产量的趋势。現将其初步結果报导出来,以供生产者的参考。并希讀者批評指正。在农业生产实踐中尤以早熟甘兰,常常于叶球未形成之前,竟至抽苔开花,一般只 I. INTRODUCTION Seeds obtained from the unripe bolting plants of Brasica oleracea L. Var.capitata L., considered by most vegetable scientists and vegetable growers, to be of no seed value. Therefore, found that such plants, all abandoned without. After three years of trial observation, we believe that the immature bolting of seeds, as the seeds of the spring production, not only can get solid leaf balls and normal production with the general method of harvesting, but also increase the yield early trend. Now its initial results reported for producer’s reference. And hope readers correct criticism. In the practice of agricultural production, especially in the early stage of sweet orchid, often in the leaves before the formation of the ball, actually to the moss flowering, generally only
