潮汐苗床给水和排水的方式

1、边灌边排式

后来在我们的试验温室搭建潮汐式灌溉给苗床的时候，发现如果每个下水口都设置一个排水电磁阀，相对代价还是较高的，我们又设计了一种边灌边排的营养液灌入和排出的方式，只是前提条件是进水的流速FI要大于水池底部有排水口的排水流速是FO，这样经过一段时间，苗床内的水位也能达到设定的水位，又节省了建造潮汐式苗床的成本。

潮汐式苗床的种植盘有三层100%新的、抗紫外老化（UV稳定）和抗化学性的高抗冲击性聚苯材料共挤而成，种植盘具有独特的排水槽设计，盘四周边缘的部位略低于中心部位，有2mm的高差，从而是水分更易蒸发的边缘部位水位高于中央，使种植效果均衡。

2、先灌后排式

我们设计了一种潮汐式灌溉自动给水和营养液回收的苗床系统（已获得发明专利授权证书），通过电磁阀控制营养液的供应，同时，所有的下水口也设置了电磁阀开关，向苗床灌入营养液的时候，所有下水口的电磁阀关闭，等到苗床中的营养液水位达到设置的水位时，营养液灌入的电磁阀停止工作，根据控制系统中设定的营养液的滞留时间，等滞留时间达到设定值时，开启下水口的电磁阀，排出潮汐式苗床滞留的营养液。

Methods of water supply and drainage in tidal nursery beds

1. Filling and lining

Later in our experimental greenhouse structures, the tidal irrigation to seedbed, found that if each drains set drainage solenoid valve, a relative price is high, we have designed an irrigation while row of nutrient solution and the pumping discharge way, but only if the water is much bigger than the velocity of FI have a drain at the bottom of the pool of drainage velocity is FO, so after a period of time, the water level can reach the level set inside the seedbed, and saves the cost of building the tidal seedbed.

The tidal seedbed of planting plate has three layers of 100% new, ultraviolet (UV) aging resistance and chemical resistance of high impact polystyrene material co-extrusion, planting plate has a unique design, sink plate around the edge of the area is slightly lower than near the center, there are 2 mm height difference, which is moisture to evaporate more edge part of the water level is higher than the central, where equilibrium effect.

2. First fill the back row

We have designed a kind of the tidal irrigation automatic feed water and nutrient recycling seedbed system (has obtained a patent for invention authorization certificate), through the electromagnetic valve control the supply of nutrient solution, at the same time, all drains also set the solenoid valve switch, the seedbed with nutrient solution, all drains electromagnetic valve closed, wait until the seedbed of nutrient solution to set the water level, water nutrient solution into the solenoid valve to stop working, and according to the specified in the control system of nutrient retention time, such as residence time to set value when open the electromagnetic valve of the drains, the tidal discharge from seedbed stranded nutrient solution.
