摘  要：
以黄瓜、萝卜和番茄种子为受体材料,采用室内培养皿生物测定方法研究葫芦瓜叶水浸液的化感作用影响,为解决生产实践中的连作障碍问题提供科学依据。结果表明:10 g/L、50 g/L、90 g/L葫芦瓜叶水浸液对黄瓜、萝卜种子萌发率均具有一定的抑制作用,受体材料发芽率均比对照低;对番茄种子萌发率表现为低浓度促进、高浓度抑制;对黄瓜幼苗株高和鲜重都表现抑制作用,对萝卜和番茄幼苗株高和鲜重则表现为,在浓度90 g/L时为抑制作用,在浓度为10 g/L、50 g/L时为促进作用;对黄瓜和萝卜幼苗的根长都表现抑制作用,对番茄幼苗的根长在浓度为10 g/L时表现促进作用,在浓度为50 g/L、90 g/L时表现抑制作用。因此,在蔬菜栽培制度中,葫芦瓜可与番茄和萝卜进行合理的轮作与间套作,但不适宜与黄瓜进行轮作或间套作。

摘  要：
The allelopathy of water extract from the leaves of Lagenaria siceraria var.hispida on the seed germination of cucumber,radish and tomato were investigated by adopting indoor petri dish bioassay in order to provide the scientific basis of continuous cropping barrier solution in production practice.It is found that the water extract at the concentrations of 10,50 and 90 g/L had significant inhibiting effects on the seed germination rates of cucumber and radish.The germination rates of cucumber and radish were lower in the treatments with 10,50 and 90 g water extract/L than in the control with distilled water.The seed germination rate of tomato was increased at lower concentrations,and decreased at higher concentration.The plant height and the fresh weight of cucumber were inhibited at all the concentrations.The plant height and the fresh weight of radish and tomato were inhibited at 90 g/L,and stimulated at 10 g/L and 50 g/L.The water extract had significant inhibiting effects at all the concentrations on the roots of cucumber and radish.The roots of tomato were stimulated at 10 g/L and inhibited at 50 and 90 g/L.It was suggested that Lagenaria siceraria var.hispida might be intercropped with tomato and radish,but should be avoided to intercrop with cucumber.
