Water-saving irrigation scheduling for transplanted cotton following wheat harvest
摘要
Abstract
To develop a suitable irrigation scheduling for transplanted cotton following wheat harvest, an experiment was conducted in non-weighting lysimeters to study effects of frequency of watering on plant growth,boll development,seed cotton yield,fiber quality and water use efficiency in 2011.The results showed that the watering at germination stage and early stage of leaf blade formation to promote seedling growth (scheduling CT1 )can enhance plant growth,but not significantly increase seed cotton yield and fiber quality,resulting in the lowest gin turnout and water use efficiency.If there are irriga-tions after cotton seedlings transplanted only,the forthcoming rainwater (scheduling CT4 )can not meet water requirement for plant growth,in consequence normal development of both bud and boll is restrained,causing a lower seed cotton yield and poor fiber quality.Compared with scheduling CT1 , the irrigation scheduling in which watering is taken place in squaring stage doesn't reduce seed cotton yield and fiber quality,but also leads to a 8.5% increased gin turnout and a 30.8% improved water use efficiency.Eventually,both water -saving and high yield can be achieved simultaneously for transplanted cotton following wheat harvest.关键词
