不同生育期连续调亏灌溉对花生生长及耗水过程的影响
Response of Growth and Water Consumption at Different Growth Stages of Peanut to Continuous Regulated Deficit Irrigation
摘要
Abstract
In order to alleviate the problem of water scarcity in northwest region of Liaoning Province and to solve the negative effect of water deficit on peanut production. Using split-plot design, the effects of three water deficit levels (55%, 65%, 70%) on growth traits, yield and water use efficiency (WUE)of peanut during flower-pegging stage and pod setting stage. The results showed that regulated deficit irrigation had compensation effect on the growth of aerial parts of peanut. Compared with the without losing water treatments (H3J3, water content of soil of water-holding capacity in the field of 70%, H that flower-pegging stage, J said pod setting stage), the water consumption of peanut in deficit treatment for single growth period (H1J3, H2J3) reduced by 297.52 m3?hm-2and 256.45 m3?hm-2, water use efficiency increased by 0.23 kg?m-3and 0.26 kg?m-3, yield increased by 148.35 kg?hm-2and 273.45 kg?hm-2. The water consumption of continuous moderate deficit treatment for different growth periods (H2J2) reduced by 497.42 m3?hm-2, water use efficiency increased by 0.48 kg?m-3and yield increased by 356.8 kg?hm-2. Although deficit treatment for single growth period (H1J3,H2J3) and continuous moderate deficit treatment for different growth periods (H2J2) significantly reduce the peanut water consumption and improve the water use efficiency and yield, but continuous moderate deficit treatment for different growth periods (H2J2) with the highest water use efficiency (1.44 kg?m-3). Therefore considering yield and water use efficiency, applying peanut using flower-pegging stage and pod setting stage continuous regulated deficit irrigation methods is more suitable for this situation of water saving in northwest region of Liaoning Province.关键词
