微咸水灌溉梭梭田间耗水量与生长关系试验研究

以微成水资源的合理开发利用和受损荒漠植被覆盖率的提高为目标,通过测坑试验,探讨了1、3、6 g/L3种矿化度处理下梭梭的田间耗水量和生长规律,结果表明,生长期内3种矿化度处理下梭梭土壤0～140 cm耗水量分别为419.83、404.59、378.66 mm,不同处理耗水量的大小随矿化度增加而减少;梭梭株高和枝长的生长...

Study on the Relation of Farm Water Consumption and Growth of Haloxylon Ammodendron under Saline Water Irrigation

In order to exploit and utilize saline water resource and improve the coverage of the suffered desert plants,by the test dig experiment,the paper studied on the farm water consumption and growth law of Haloxylon ammodendron in the treatments of the irrigation water 1,3,6 g/L.The results are as follows: in the period of plant growth,the water consumption of Haloxylon ammodendron in the 0~140 cm soil range is 419.83,404.59,378.66 mm,the water consumption order of different treatments is ET1 g/L>ET3 g/L>ET6 g/L;the height and branches growth rate of Haloxylon ammodendron appeared as single-peak curve,the canopies growth rate appeared as two-peak curve;increasing the water consumption,the growth and water consumption of Haloxylon ammodendron showed the trend of the quickness,slowness,less slowness(hardly stop growing),the amount of growth of the canopies and branches match the good logarithm number function relation.
