[Effects of fertilization on cotton growth and nitrogen use efficiency under salinity stress].

Cotton (Gossypium hirsutum) was raised at different salinity levels (0, 0.15% and 0.30%) by irrigating with fresh- or sea-water.

[Regulation effects of various training modes on source-sink relation of cotton].

With the removal of vegetative branches plus the maintenance of early fruiting branches as the control, the effects of various training modes on the source-sink relation of field-grown cotton were examined in 2005 and 2006. The results showed that compared with the control, either the removal of vegetative branches plus the removal of early fruiting branches (I), the maintenance of vegetative branches plus the removal of early fruiting branches (II), or the maintenance of vegetative branches plus the maintenance of early fruiting branches (III) could increase the leaf area per plant significantly, with the average maximum LAI across the two years increased by 10.3%, 28.
