为解决生产实践中的连作障碍问题提供科学依据,以韭菜茎叶水提液分别浸泡油菜、白菜和萝卜的种子,在培养皿滤纸上使其发芽,测定韭菜水提液对油菜、白菜和萝卜幼苗的根长、苗高和鲜重的影响。结果表明,韭菜的地上部分的水提液对油菜、白菜和萝卜种子的萌发及其幼苗生长有明显的抑制作用,且不同浓度水提液对不同蔬菜的影响存在差异,在一定条件下浓度越高
In order to provide a scientific basis for solving the problem of continuous cropping obstacle in production practice, the seeds of rape, cabbage and radish were immersed in leek water extract to germinate on the filter paper of petri dish. The water extract of leek to rape, cabbage and radish Seedling root length, seedling height and fresh weight. The results showed that aqueous extract of the aerial parts of Chinese chives significantly inhibited the germination and seedling growth of rapeseed, cabbage and radish, and the effects of different concentrations of aqueous extracts on different vegetables were different. Under certain conditions, high
