潮汐式灌溉方式（歐美稱tidal或ebb and flood）是基于潮水漲落現(xiàn)象設(shè)計而命名的一種節(jié)水灌溉方式。該方式利用了育苗穴盤底部的排水孔，在灌溉時使水位沒過排水孔，水分自下面上地被基質(zhì)自然吸入，既保持了葉面干燥，又可防止淋洗式灌溉導(dǎo)致的肥水流失，適用于各類盆器及穴盤栽培植物的種植管理。微環(huán)境恒溫育苗床通過潮汐式底部補水方式，使根基環(huán)境自然達到相宜的含水量，地暖使用發(fā)熱均勻的電鍍膜取代傳統(tǒng)電熱線作為恒溫?zé)嵩?，電熱膜的熱點轉(zhuǎn)換率要點熱心，且為面狀加熱，膜上各點發(fā)熱量均相同。

穴盤育苗作為一種現(xiàn)代化的無土栽培方式育苗技術(shù)體系，具備一次性成苗，病蟲害發(fā)生率低，種苗品質(zhì)高度可控以及可大規(guī)模工業(yè)化生產(chǎn)等優(yōu)勢特點，該技術(shù)體系集成了育苗穴盤，玻璃溫室，鋼架育苗床，自動播種與特種灌溉設(shè)備等栽培設(shè)施，是目前世界上主流的植物種苗生產(chǎn)方式。然而多數(shù)生產(chǎn)者為了降低生產(chǎn)成本，在實際應(yīng)用種往往將育苗穴盤排放在大田中的簡易土床內(nèi)，使用傳統(tǒng)的人工噴淋法補水，冬季通過鋪設(shè)電加溫線及搭建小拱棚進行加溫保溫。穴盤育苗技術(shù)在此等“減配”條件下運動具有諸多弊端，1：在臺風(fēng)多雨季節(jié)，育苗場地極易受洪澇積水影響，2：土壤具有一定導(dǎo)熱性，冬季育苗時，熱量易通過底部土壤流失，使得加溫能耗較高，3：噴淋式的補水方式灌溉均勻度較差，肥水浪費大，4：由噴淋式灌溉造成的頁面表面濕度較高，極易滋生各種病害，是引發(fā)各種苗期病害的重要原因，此外，育苗過程中遇到較低氣溫時，需對幼苗生長環(huán)境驚醒加溫保溫。潮汐苗床是一種能源利用率高，病害發(fā)生率低的的催芽培育一體化微環(huán)境恒溫育苗床，通過搭建育苗床面保溫小拱棚，壓縮育苗棚內(nèi)保溫的三維空間，，使維持育苗環(huán)境溫度所消耗的能量低。河北省衡水市華耀農(nóng)業(yè)設(shè)施工程有限公司潮汐式灌溉移動苗床栽培床是一種床面為塑料結(jié)構(gòu)的栽培床，其床面采用塑料制作的潮汐式苗盤，它又稱底部灌溉式栽培床.
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 , the production reaching standard,every plants with same height and high quality.
