Effect of farmland windbreak on preventing cotton lodging and its yield reduction under violent tropical storm

Abstract

Abstract: The studies show that within the scope of 27 H from sheltered side of farmland windbreak, forest net has the functions of reducing cotton lodging and its yield loss to a certain extent.The effective protection zone ranges from 0.42 to 23 H, and the maximum effective zone for unginned cotton yield and gin turnout percentage is from 10 H to 13 H. Compared with damaged zone, protection zone has an increase of 45.01% for unginned cotton yield and 52.69% for ginned one. Within the whole forest net, the unginned cotton yield is increased by 29.9%, and the gined one by 35.06%.

Key words: Farmland windbreak, Violent tropical storm, Cotton yield
