潮汐式灌溉移動苗床係統特點

1.潮汐式灌溉移動苗床是一項成熟的農業灌溉技術,在發達國家得到了廣泛利用,很好的解決了灌溉與供養的矛盾,且灌溉基本不破壞基質的“三相”構成,是一項高效高能的農業技術,在我國也處於廣泛的利用發展階段。

2.節水高效,完全封閉的係統循環,可以達到90%的利用率。

3.植物生長的速度更快,每周苗齡可比傳統育苗方式提前1天,提高設施利用率。

4.避免植物葉麵產生水膜,使葉片接受更多的光照行光合作用,促使蒸騰拉力從根部吸收更多的營養元素。

5.穩定的根部介質水氣含量,避免毛細根因靠近容器邊部及底部幹旱而死。

6.相對的濕度容易控製,保持葉麵幹燥,減少化學藥物的使用量。

7.植床下無雜草生長,減少菌類滋生,因為植床下非常幹燥。

8.管理成本降低,無論是手動操作或輔助以微電腦控製器管理下,一個人在20-30min內可完成0.2~0.5ha.穴盤苗的灌溉。

9.可以隨時使用,不受品種,規格,時間限製。

10.一般的噴灌方法,令每棵植物吸收肥料及水分不平均,令成品率下降,而抄襲灌溉成品率市100%。而且生產達到標準化,每棵植物高度統一,質量有保證。

Features and advantages of ebb-and flood ben ches 

-adn flood roling benches is a kind of mature irrigation tecfnoloy and is widely used in developed  sovied the "solid phase,liquid phses and gaseous phase composition"of the -and-flood rolling benches is a is on hte stage of developing in our country.

saving,high efficiency and competely closed circulatory system make the utilization rate reaches90%.

plants grow faster,It is 1day ahead of traditional seeding method for age of seeding per week ,which can enhance the facility utilization rate.

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.

media moisture content to avoid the root capillary from iry death because of reaching the con tain er bottom or edge

to control the relative humidity to keep the fungus because it is dry under the using of chemicals.

s under the benches to reduce the fungus because it is dry under the benches

management  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

can be used any time and not limited by bariety,specification and time.

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 ">

潮汐式灌溉移動苗床栽培床是一種床麵為塑料結構的栽培床,其床麵采用塑料製作的潮汐式苗盤,它又稱底部灌溉式栽培床。這種潮汐式灌溉移動苗床采用基本與商品化金屬結構栽培床相同的立柱、支撐,床麵采用模壓成型的不透水塑料苗盤。灌溉時,苗盤內注滿清水或營養液,並使其滯留一定的時間,以使作物依靠毛細作用通過花盆底部的排水孔吸收水分。之後灌溉水排出栽培床,或收集再利用,或直接排到當地的下水管道。

潮汐式灌溉移動苗床是 一種針對盆栽植物營養液栽培或容器育苗和無土栽培所設計的底部給水的的灌溉方式。該方式利用落差原理,實現定時給水與施肥。國內外大量的試驗研究表 明,采用潮汐灌溉方式的作物,其生長量明顯優於人工澆灌方式,不但能降低壞疽葉和皺折葉的發生,還可減少用水量達33%,提高水分利用效率達40%。由於 潮汐灌溉沒有淋浴作用,還能減少氮素使用量達30%~35%,大大提高氮素的利用效率。
