The fast numerous sprayer unit of a kind of plant cuttage
Technical field
The invention belongs to agricultural engineering field, be specifically related to the fast numerous sprayer unit of a kind of plant cuttage.
Background technology
In plant propagation nursery, conventional field cuttage is often by the restriction of the factors such as season, environment and cuttage operating process, and the important indicator such as rooting rate, survival rate, root quantity, breeding cycle also improves a lot space.
The soil humidity that different phase is suitable for affects the decisive factor of taking root.Full exposure spraying cuttage technique is the more advanced nursery stock cuttage and quick-propagation technology of current techniques and equipment, its core technology is temp. and humidity induction system by microcomputerized control and intelligent sprayer unit, continuous adjustment and spray time and interval time, to control cuttage environment and matrix temp. and humidity.Complete equipment automatic controlling level is high, is very applicable to factorial praluction.But, also there is some deficiency in this technology in production, and as its scale of investment is comparatively large, only control system needs about 80,000 yuan; Temp. and humidity inductor belongs to high sensitive electronic equipment, and unit price is also more than ten thousand yuan, careless slightly, and very easily damage, service life is shorter, and market is difficult to buy supporting substitute products; Temp regulating function is difficult to realize, and needs to consume mass energy, even causes environmental pollution to a certain degree; Whole rooting process requires long-term spraying, large to water demand.Just because of this, this technology is difficult to meet market to cultivating seedlings low cost, the requirement that easy and simple to handle, reproduction speed is fast.Some seedling cycles short, simple to operate and practical rapid seedling cultivation device that application value is high is starved of in production reality.
Summary of the invention
The fast numerous sprayer unit of a kind of plant cuttage of the present invention, is made up of humidity controller, humidity sensor, contactor, timer, water pipe, water pump, shower nozzle, filter, switch, electric wire etc.Be achieved through the following technical solutions: (1) connecting power line, switch, humidity controller, contactor and humidity sensor, composition moisture control system.(2) connecting power line, switch, timer, contactor, forms manual moisture control system.(3) connecting power line, contactor, water pump, filter, water pipe and shower nozzle, composition spraying system.Each device power supply (DPS) voltage is 220V, and the scope of humidity controller is 50-100%, minimum resolution 1% or following and with supporting humidity sensor.Select humidity controller adjustable spraying system works, its work is according to the humidity being induction stromal surface automatically, more can accurate assurance cuttings ambient conditions, humidity required by cuttage rooting is provided, can effectively avoids excess moisture, humidity is excessive and the phenomenon of the cuttings perish caused and water resource waste.
In earlier stage, enable humidity controller adjustable spraying system works, when sensor sensing stromal surface humidity is lower than controller setting value, controller is energized cuttage and quick-propagation to contactor, also with regard to feed pump energising while contactor is closed, thus starts spraying increase humidity.When the peak that sensor sensing stromal surface humidity sets higher than controller, controller disconnects contactor power supply, and contactor also stopped water pump while disconnecting and powers, thus stops spraying.
After cuttage starts to take root, disconnect humid control appliance mains switch in time, start timer power supply, change timing controlled spraying into, the interval time arranging spraying is 8-12 hour, and each spray time is 2-10 minute, root growth can be promoted further, reduce unnecessary water resource waste.After reaching setting value interval time, timer is energized to contactor, also with regard to feed pump energising while contactor is closed, thus starts spraying increase humidity.After reaching setting value when sprayed, timer disconnects contactor power supply, and contactor also stopped water pump while disconnecting and powers, thus stops spraying.
Advantage of the present invention is:
1, equipment and materials is easy to get, and installation cost is cheap, does not need a large amount of input.Each control device and material all can be bought in specialty on the market, and price is also more cheap.Once drop into, can reuse for a long time.
2, humid control is respond well, obvious hestening rooting, shortens the seedling propagation cycle.
3, water-saving result is obvious, and the timing controlled particularly after cuttage root-taking, both facilitated plant root growth, again saved a large amount of water resources.
4, simple to operate, be easy to management.The construction of whole device belongs to basic hydropower installation, and process is simple, without special professional technique requirement, is very suitable for individual and enterprise carries out batch production botanical seedling culturing production development.

Specific embodiment:
The present invention is positioned at base, nursery, Bai Xiang town, Yueyang County, Hunan Province, carries out assembling implement in mid or late August, 2012.The present embodiment humidity controller, humidity sensor, contactor, timer, water pipe, water pump, shower nozzle, filter, switch, electric wire etc. used is all from local building materials and electronic market.Device assembles implementation step is as follows: 1, connect power switch (10), humidity controller (9), contactor (11) and humidity sensor (8), composition moisture control system.2, connect power switch (13), timer (1), contactor (11), form manual moisture control system.3, power supply (12), contactor (11), water pump (3), filter (4), water pipe (2,5) and shower nozzle (6) is connected, composition spraying system.
The present embodiment is used for spindle tree cuttage and quick-propagation.Cuttage in earlier stage, in fast numerous sprayer unit, humidity controller arranges humidity range 75-76%, humidity controller adjustable spraying system works is enabled on September 18th, 2012, when sensor sensing stromal surface humidity lower than 75% time, controller is energized to contactor, and the energising of contactor closed also feed pump, starts spraying.When sensor sensing stromal surface humidity is more than 76%, controller disconnects contactor power supply, and contactor also stops water pump powering while disconnecting, thus stops spraying.Disconnect humid control appliance mains switch on September 28th, 2012, start timer power supply, change timing controlled spraying into, the interval time arranging spraying is 8 hours, and each spray time is 2 minutes.Reach 8 constantly little when interval time, timer is energized to contactor, and contactor closes, water pump energising work, starts spray humidification.2 are reached when sprayed/, timer disconnects contactor power supply, and water pump quits work, and spraying stops.
