Experiments of bioremediation and control were conducted with the alkali meadow grass planted in saline soil for 3 years. Contrasted with control group, topsoil desalination rate was up to 77.00%; pH value decreased 0.25 pH unit; soil bulk density decreased 0.14 g/m^3; total porosity increased by 5.29%; soil aggregate structure increased by 23.14%; soil water content increased 70.30 g/kg; average triennial alkali grass yield was 36000 kg/hm^2. In addition, planting forage in saline soil as a medium and establishing a compound agro-forestry-animal system promoted the sound combination of planting industry, forestry, and livestock husbandry. Because of the reasons, utilization ratio of land reached more than 184.00%; the income of land increased from 16300 to 35500 yuan/hm^2 average income per farmer in the controlling region increased by 66.00%, from 2160.70 to 1300.80 yuan.

生物修复与调控试验研究表明,草甸盐土经种植碱茅草3a,耕层土壤与对照相比脱盐率达77.00%,pH值下降了0.25个单位,容重降低0.14g/立方公尺,总孔隙度增加5.29%,团粒结构增加了23.14%,自然含水量增加70.30g/kg.3年生碱茅草平均产草量36000 kg/hm^2;盐化耕地采用以种植牧草为中介,将种植业与农区林业、畜牧业有机结合成互相依存,互相促进的农林牧复合生物系统治理后,土地利用率可达184.00%以上,可获得16300~35500元/hm^2的经济收入,治理区农户人均纯收入由1300.80元增加到2160.70元,增加了66.00%。

It consists of various halophytes (plants that can live in salty soils), with a predominance of mangroves.

它是由多种盐土植物组成(指:那些可以在含有盐分的土壤中生存的植物),主要是红树林。

Halophytes are adapted to obtain water from soil water with a higher osmotic pressure than normal soil water, so they need to be able to accumulate a high concentration of salts in their root cells.

盐土植物的渗透压高于土壤,这样就可以从土壤中吸收水分,所以它们的根细胞中积累了高浓度的盐分。
