茜草科的猪殃殃(Galium aparine L.Var。tenerum(Gren.et Godr.)Rebb.),紫草科的麦家公(Lithospermum arvense L.),豆科的大巢菜(Vieia sativa L.)和禾本科的野燕麦(Avena fatua L.)是苏北垦区麦田四大恶性杂草,也广泛分布于国内外广大小麦产区。
During 1971-19839 through the observation of weeds in the garden and the field,the biology and ecology of the malign weeds Catchweed bedstrau(Galium aparine L.var.tenerum(Greu.et Godr.)Rebb.),coru gromwell(Lithos-permum arvense L.),common vetch(Uicia sativa L.)and wild oat(Avena fatua L.)in the wheat fields of North Jiangsu Province were studied.At the same time the law of their occurrence and distribution,their adaptive ability to the conditions of climate and soil,the development of their emergence and death in the field,the distribution and growth of weed’s seeds in different plough horizons and their damages to the yields of wheat were also studied.From these studies we have obtained the best prescription and spraying period for controlling weeds with Beadazon,Propanil,Avadex and Phenoxy—acid herbicides,and achieved good increase in the output of wheat.
