Description

Water-cultivating irrigation device

The utility model relates to a kind of agriculture watering apparatus, particularly relates to a kind of vertical flow type water-cultivating irrigation device that is arranged on short the middle section water ploughing system in type greenhouse, room that is connected into by pipe support.

By water-cultivating technology in the past,, replace the cultivated Agricultural Development trend of tradition soil and become because of having precision agriculture, reduce residue of pesticide, reducing important breakthroughs such as insect pest and enhancement agricultural product edible safety.Plough cultivation of plants and observe water, so its emphasis mainly among the promptly general alleged nutrient solution or foster liquid of water-soluble very much liquid with nutrition, fully absorbs along with in good time, an amount of supply of each growth stage of plant gives plant.And nutrient solution is when pouring in cultivation bed, removes for the nutrient solution that pours into again and must in addition the fixing, also must be eliminated replacing earlier to the nutrient solution that was last time retained, otherwise will cause having following two shortcomings generation with water-level control apparatus:

1, last time retaining in the nutrient solution in the cultivation bed does not change if give all eliminating, to the nutrient solution that pour into again be mixed with the nutrient solution that is last time retained, and reduced the freshness that newly pours into nutrient solution relatively, and cause a Nei Ge district to form nutrient solution new, old mixing, the uneven phenomenon in each district takes place, it will cause the Nutrient Absorption inequality for plant, form the uneven phenomenon of progress degree, making the same district is that institute educates plant maturity and differs in the same cultivation bed, can't a harvest, cause agriculture operator's inconvenience.

2, last time retained in the interior nutrient solution of cultivation bed, if mix with the nutrient solution that pours into again, newly pour into the freshness of nutrient solution except that having reduced, mainly run off totally because of the old nutrient of supporting in the liquid of depositing, the nutrient density of mixotrophism liquid reduces relatively, feasible amount of nutrients of originally being scheduled to, and must doing more, the new nutrient solution of volume pours into, mix the loss part cause to supply, cause the increase of nutrient solution consumption and cause waste by the old nutrient solution of depositing; And,, promptly must be simultaneously old depositing be supported liquid and discharged because of when pouring into new nutrient solution; And under the situation that new, old nutrient solution mixes, the nutrient solution that will partly newly pour into has been discharged simultaneously in fact; Even partly bad cultivation bed, because of factor such as dead angle, backflow in the bed, on the contrary old nutrient solution is stayed, discharge and push new nutrient solution, more cause the cost that meaningless waste reaches has significantly increased water-cultivating, meet economic principle really anything but.

Irritate the shortcoming of arranging for aforementioned the 1st, the 2nd custom formula water-cultivating nutrient solution, in the cultivation bed structure that the cultivated industry of current water is adopted,, only lift following two examples as an illustration now still for common:

1, see also shown in Figure 1, this graph structure is the Taiwan notification number No. 79205740, the patent case cultivation bed structure that number No. 142485 the patent case is adopted, this simple type cultivation bed 2, be bed groove 21 stage casings of holding sealing therein, the terminal together dividing plate 22 that is provided with through port 23 of tabula, the new nutrient solution WN that its feed liquor portion 24 is imported, after through the turnover of through port 23 places, row discharges at discharge opeing portion 25 places of side in addition to being positioned at feed liquor portion 24; Its theory no doubt is to push old nutrient solution WO reach by new nutrient solution WN, and discharges in advance; But because of the water channel of its wide cut shape, the feasible new nutrient solution WN that is imported, absolutely not wide cut, the old nutrient solution WO reach of propelling in step; To be on the contrary let alone to overflow, sinuous flow.Thereby the inner side edge of the turning point, right angle, many places in cultivation bed groove 21, very easily generation makes old nutrient solution WO lodge in position, the dead angle H1 at this place; And the new nutrient solution WN that should flow only can be pushed and formed the backflow phenomenon H2 that the original place rotates by the side of this old nutrient solution WO; This kind situation all will cause mixing phenomena new as described above, old nutrient solution, or the shortcoming of the nutrient solution that will newly pour on the contrary discharge, so do not conform to practicality.
