潮汐式灌溉移动苗床系统特点
1.潮汐式灌溉移动苗床是一项成熟的农业灌溉技术，在发达国家得到了广泛利用，很好的解决了灌溉与供养的矛盾，且灌溉基本不破坏基质的“三相”构成，是一项高效高能的农业技术，在我国也处于广泛的利用发展阶段。
2.节水高效，完全封闭的系统循环，可以达到90%的利用率。
3.植物生长的速度更快，每周苗龄可比传统育苗方式提前1天，提高设施利用率。
4.避免植物叶面产生水膜，使叶片接受更多的光照行光合作用，促使蒸腾拉力从根部吸收更多的营养元素。
5.稳定的根部介质水气含量，避免毛细根因靠近容器边部及底部干旱而死。
6.相对的湿度容易控制，保持叶面干燥，减少化学药物的使用量。
7.植床下无杂草生长，减少菌类滋生，因为植床下非常干燥。
8.管理成本降低，无论是手动操作或辅助以微电脑控制器管理下，一个人在20-30min内可完成0.2~0.5ha.穴盘苗的灌溉。
9.可以随时使用，不受品种，规格，时间限制。
10.一般的喷灌方法，令每棵植物吸收肥料及水分不平均，令成品率下降，而抄袭灌溉成品率市100%。而且生产达到标准化，每棵植物高度统一，质量有保证。


Features and advantages of ebb-and flood ben ches 
1.Ebb-adn flood roling benches is a kind of mature irrigation tecfnoloy and is widely used in developed countries.It sovied the "solid phase,liquid phses and gaseous phase composition"of the media.Ebb-and-flood rolling benches is a is on hte stage of developing in our country.
2.Water saving,high efficiency and competely closed circulatory system make the utilization rate reaches90%.
3.The plants grow faster,It is 1day ahead of traditional seeding method for age of seeding per week ,which can enhance the facility utilization rate.
4.It can protect the leaf from water film in surface,therefore the leaf can get more 
 light to have photosynthesis, which can promote the transpiration pull and the root
 can absorb more nutrients.
5.Stable media moisture content to avoid the root capillary from iry death because of reaching the con tain er bottom or edge
6.Easy to control the relative humidity to keep the fungus because it is dry under the using of chemicals.
7.Noweeds under the benches to reduce the fungus because it is dry under the benches
8.Low management cost.No matter hand orerating or with help of microcomputer contorol management,a person can finish the irrigation of 0.2 to 0.5 ha flat benches in 20 to 30 minutes
9.It can be used any time and not limited by bariety,specification and time.
10.The normal sprinkling irrigation can not distribute the fertilizer and water equally and lead to the yield declining .However,the ebb-and-flood irritation can make sure the yield 100%, the production reaching standard,every plants with same height and high quality.



潮汐式灌溉移动苗床栽培床是一种床面为塑料结构的栽培床，其床面采用塑料制作的潮汐式苗盘，它又称底部灌溉式栽培床。这种潮汐式灌溉移动苗床采用基本与商品化金属结构栽培床相同的立柱、支撑，床面采用模压成型的不透水塑料苗盘。灌溉时，苗盘内注满清水或营养液，并使其滞留一定的时间，以使作物依靠毛细作用通过花盆底部的排水孔吸收水分。之后灌溉水排出栽培床，或收集再利用，或直接排到当地的下水管道。



潮汐式灌溉移动苗床是 一种针对盆栽植物营养液栽培或容器育苗和无土栽培所设计的底部给水的先进的灌溉方式。该方式利用落差原理，实现定时给水与施肥。国内外大量的试验研究表 明，采用潮汐灌溉方式的作物，其生长量明显优于人工浇灌方式，不但能降低坏疽叶和皱折叶的发生，还可减少用水量达33%，提高水分利用效率达40%。由于 潮汐灌溉没有淋浴作用，还能减少氮素使用量达30%~35%，大大提高氮素的利用效率。
