Abstract

This article is on the variety,distribution and regularity of weeds in flax fields.There are 101 weeds,belonging to 25 families.26 of them,belonging to 7 families,cause damage.Among them,77 are dicoty ledonous,22 are monocoty ledonous and 2 are fern,or 42 are annual,29 are biyearly and 30 are perennual. Weeds grow after sowing of flax and reach the highest density of 88-1230 weeds per square meters 90%of the weeds could be kiued by spraying diuron 50%and quizalop-P-ethy15%or diuron50%and MCPA-Na56%with water at the fer-needle stage (flax height5-8cm).
