| Abstract: | Investigation wheat field in six countys of Guanzhong west area in Shaanxi province was made.There are 22 species of weeds belonging to 22 genera of 10 families.Among them,10 species weeds caused serious damage.The whole Guanzhong west area may be divided into 6 kinds of weed-infested districts.There are more differences on weed species and major weed community forms and distribut ion of weeds in different districts.Excepting for geographic conditions,influenceing elements of weed distribution are transmitting of people''s action and cultivation and rain-fall and chemical control measures atc.Different weeding periods have a great influence upon wheat yield loss.Wheat yield loss rate was 0.16%~2.07% and 6.41%~16.19% the before and the after wheat jointing for weeding control.According to the area weeds damage,experiments of weed control effect for application herbicides in wheat field and mixed application technique of these herbicides have been studied. |
