盐胁迫对甜瓜水分利用率的影响

- Effects of Salt Stress on Water Use Efficiency of Melon

- 摘要:
- 采用蒸进仪(Lysimeter)方法研究了不同盐分浓度和不同灌水量条件下,盐、水因素对甜瓜水分利用率的影响.结果表明,当灌溉水平较低时,甜瓜产量主要受灌溉水平影响.当灌水量达到一定水平后,盐分的危害将明显地表现出来.甜瓜水分利用率较高的处理出现在Ec为3或6mΩ/cm的Lysimeter中.过淡或过浓(如Ec为1.2或9mΩ/cm)的灌溉水,均不利于甜瓜水分利用率的提高.自然,合宜的灌溉水质与水量的选择,不仅仅取决于甜瓜的水分利用效率.还应考虑甜瓜的
- Abstract:
- Effects of salt and water on water use efficiency of melon under different salinity and different irrigation norms were studied using lysimeter.The results show that the yields of melon are mainly affected by irrigtion norm under the low irrigation norms condition.If we irrigated more water than a certain norm,the melon would suffer salt damage apparently.For those lysimeters receiving-treatments that Ec is 3 or 6mΩ/cm for irrigation water,the water use efficiencies of melon seem to be higher than those.of others.It is difficult to improve water use efficiency if the salt content in irrigation water is extremely low or extremely high(e.g.Ec is 1.2 or 9mΩ/cm).Certainly,rational water quality and amount of irrigation water are determined not only by water use efficiency of melon but also by other indexes such as yield and quality of melon.
