中文摘要	以美国油料向日葵G101为材料,研究在干旱区不同水盐处理对作物(油葵)的生理性状及产量形成的影响.结果表明:作物群体叶面积、叶片水势和产量随土壤含盐量的增加而呈下降趋势.在不同水盐处理下,轻度盐土结合(55%～65%)thetafc的水分处理是适宜的.含水率在(65%～75%)thetafc,含盐量在0.3%～0.5%时对油葵的生长及最终产量的形成影响不大,其叶面积指数、叶水势和产量与轻度盐土的分别相差5.90%、0.27 MPa和5.92%.而含盐量超过0.5%时,高水分处理也对油葵的生长及最终产量的形成产生严重抑制,其产量是轻盐土的57.39%,低水分处理减产率达62.32%.
英文摘要	The American sunflower G101 was planted in field, effect of difference water-salt treatment on crop physiological process and yields formation were studied in the arid areas. The main findings are as follows-Index of leaves, leaf potential and yield decreased while soil salinity increasing. In the different water-salt treatment, it is feasible while soil salinity is 0. 2%~0. 3% and soil moisture is (55%~65%)theta_(fc). It did certain harm to crop growth under soil moisture is(65%- 75%)theta_(fc) and soil salinity is 0. 3%~0. 5%, but the harm was little. Index of leaves, leaf potential and yield was 5. 90%, 0. 27 MPa, and 5. 92% of the light salt stress respectively. But when soil salinity >0. 5%, although high water treatment (soil moisture is 65%~75%theta_(fc)) had serious harm to plant growth and final output. Output was 57. 39% of light salt soil’, the ratio of decreased output was 62. 32% under low water treatment (soil moisture is 55%~65%theta_(fc)).
