摘要: 以黄瓜(Cucumis sativus L.),萝卜(Raphanus sativus L.)和白菜(Brassica chinensis L.)3种蔬菜作物为受体,通过种子萌发试验及幼苗生长试验,对分葱(Allium fistulosum L.var.caespitosum Makino)根系及其地上部水浸液的化感作用进行了初步研究。结果表明:分葱根系和地上部水浸液对黄瓜、萝卜和白菜具有一定的化感作用。对黄瓜和萝卜的萌发有一定的抑制作用,而对其幼苗生长有一定的促进作用;对白菜的萌发表现为低浓度促进高浓度抑制,而对其幼苗生长有一定的抑制作用。因此,在蔬菜栽培制度中,分葱可与黄瓜和萝卜进行合理的轮作与间套作;但可能不适宜与白菜进行轮作或间套作。

Abstract: A preliminary study was made on the allelopathy of Allium fistulosum L.var.caespitosum Makino on Cucumis sativus L., Raphanus sativus L.and Brassica chinensis L.. The results showed that the root and the aqueous extract from aerial part of Allium fistulosum L.var.caespitosum Makino had some inhibit effects on the germination of seed of Cucumis sativus L.and Raphanus sativus L., while had some stimulat effects on their growth of seedling.And they showed different allelopathy on the germination of seed of Brassica chinensis L.,while had some inhibit effects on its growth of seedling. It was suggested that Allium fistulosum L .var. caespitosum Makino should be intercropped with Cucumis sativus L. and Raphanus sativus L., while should be avoided to intercrop with Brassica chinensis L..
