分析干旱和复水环境中植物水势特征,对探讨植物水分状况对土壤水分环境的响应机制具有重要意义.为探索侧柏水势对干旱与复水环境的响应特征,通过温室盆栽试验,研究干旱胁迫与复水环境对侧柏苗木不同生长阶段水势的影响.结果表明,土壤含水量、干旱持续时间、苗木生长时期以及各因素之间的相互作用对侧柏苗木水势均产生了极显著的影响(P<0.01).随着干旱程度加剧,侧柏苗木水势呈下降趋势,水分胁迫指数呈上升趋势.40.00％SWC处理的苗木水势下降幅度达到最大,其中干旱15 d的生长初期、生长中期和生长后期的苗木水势分别比对照下降了1.46、1.10、1.84 MPa.复水后,侧柏苗木3个生长时期水势逐渐恢复,恢复速率与干旱程度、干旱持续时间和生长时期相关.随着供水时间的延长,复水激发了侧柏苗木水势的补偿作用,苗木生长中期阶段水势恢复快于生长初期和生长后期阶段,在复水72 h后逐渐接近对照水平.

[Objective] To increase the high-quality forage supply for livestock in Anshun region,and solve the shortage of forage grass.[Method] Introduction trial of two annual Triticale variety of forages was carried out in the Baiyan area of Anshun in 2015,indexes of tiller number,ear length and yield and so on were determined.[Result] forage-height of Xiaoheimai 635 and Zhongsi 1 triticale was 175.33 cm and 175.22 cm,tiller number of two forage grasses was 11 and 12,and hay yield of them was 10 388.03 kg/hm2 and 11 863.02 kg/hm2,respectively.[Conclusion]Xiaoheimai 635 and Zhongsi 1 Triticale can adapt to the local climate and soil in Baiyan area.
