Description

Autocontrol plant soil-less culturing device

The utility model is a class cultivator that is used for plant soil-less culturing.

The plant soil-less culturing of monomer is formed by planting body, matrix, nutrient solution and cultivator.The growth of plant directly is subjected to the aqueous vapor balance in root district, the influence of the concentration of nutrient solution, pH value, the temperature difference and ambient humidity.

For creating the rhizosphere condition of suitable plant growing, the plant soil-less culturing technology of monomer is to take to regulate the porosity control WGR of matrix at present, offer the upper limit of spout hole restriction rhizosphere water level, inhale the control water yield that supplies water with the porous material hair, and often clean measure and methods such as matrix and molten device.What the nutrition confession basin on the market adopted is exactly above-mentioned basic skills.But these technology are too complicated to masses' technology, and lack of standardization, are difficult for during application grasping.

The purpose of this utility model is that a kind of superior performance, the simple autocontrol plant soil-less culturing device of use will be provided, it is constant that it can effectively control the rhizosphere water level automatically with self its specific structure, guarantee root district aqueous vapor balance, regulate ambient humidity, safeguard that the concentration of nutrient solution and pH value are stable.

The purpose of this utility model is achieved in that according to the purposes of water structurally divides upper, middle and lower-ranking, and the centre is provided with the alms bowl of planting of cultivated plant.It is evaporation layer at the middle and upper levels, and the middle level is the storage liquid layer, and lower floor is the feed flow layer, and the center is a venting cavity.The alms bowl of planting passes, in two-layerly place venting cavity to the lower floor bottom, in pretend to a spot of cultivation matrix transmission nutrient solution and fixing plant.

Adorn common water in the evaporation layer, be looped around plant around, open in the air, the evaporation of moisture content is relevant with ambient temperature and humidity, evaporation discharge is big under the environment of high-temperature drying, the steaming amount is little under the environment of low temperature and moisture.Therefore has the function of regulating ambient humidity.

Storage nutrient solution in the storage liquid layer, when the feed flow aspect of lower floor is lower than the water level control pipe mouth, end when nutrient solution wherein will flow out automatically and be supplemented to the feed flow face and seal the water level control pipe mouth, guarantee that feed flow layer liquid level fluctuates in very little scope, thereby realize the automatic control of the permanent water level of rhizosphere.

The bottom of the feed flow layer accommodating plant root system and the alms bowl of planting.Provide nutrition and moisture content to plant with constant water level, most important technical conditions when the constant control of rhizosphere water level is soilless culture, it can effectively prevent to suffocate because of the liquid level mashed and root of the root-rot that causes that fluctuates widely.

The alms bowl of planting is the mesh structural porous body of hollow round platform shape, and interior dress is the matrix of plant fixedly, inhales nutrient solution from feed flow layer hair and carry moisture content and nutrient in the alms bowl body.The plant seedling of newly planting is fully by this approach growth.The intrinsic physical property of matrix determines the size of its water-holding capacity, and the matrix of suitable soilless culture can both guarantee its inner suitable WGR automatically, need not artificial adjustment (for example rock wool).The root system of growth will pass mesh and enter in the venting cavity and breathe, and a part enters and absorbs moisture content and nutrient in the feed flow layer nutrient solution.

The above cavity of feed flow layer liquid level partly is a venting cavity, gas is wherein exchanged by ventilation hole, the size of pore and quantity determine the wherein content and the air humidity of oxygen, as long as it is reasonable in design in the manufacture process, its WGR will be controlled in the suitable scope, good environment has been brought up in the root system of plant breathing that exists for of venting cavity, and can promote being differentiated to form of function root.

The aqueous vapor environment brought up of intrinsic aqueous vapor environment of matrix and venting cavity is exactly the aqueous vapor environment in plant roots district, thereby realizes the automatic control of root district aqueous vapor balance in sum.

Store the water in liquid layer and the feed flow layer, be distributed in the inside configuration of cultivator, the evaporation discharge of nature is very little, and the overwhelming majority is absorbed by root system of plant.Water in the evaporation layer independently exists, and its evaporation does not influence the change of nutrient solution concentration.So the availability of nutrient solution is very high.

Because the minimizing of moisture content natural loss increases fluid infusion blanking time.Observe in the reality, in general one month summer, in two months winters, mend one time of nutrition liquid and get final product.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the half-sectional view according to the autocontrol plant soil-less culturing device that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete cultivator that the utility model proposes.

This cultivator comprises evaporation layer (9), storage liquid layer (1), and feed flow layer (4), the alms bowl of planting four parts such as (5) combine.

In evaporation layer (9), add common water.In storage liquid layer (1), add nutrient solution or water and corresponding granular fertilizer (among embodiment Fig. 1, the storage liquid layer can take off and add water).When the liquid level in the feed flow layer (4) is lower than water level control pipe mouth (3), under the effect of atmospheric pressure, air will enter in the storage liquid layer (1) automatically, and nutrient solution is flowed in the feed flow layer (4) automatically by supply opening (2), ends during to liquid level sealing water level control pipe mouth (3).The alms bowl (5) of planting passes evaporation layer (9) and storage liquid layer (1) places in the ventilation accumulation body (6), stand in the nutrient solution in the feed flow layer (4), in it root system of growth absorb nutrient solution make feed flow layer liquid level (4) drop to water level control pipe mouth (3) when just exposing former balance destroy, the nutrient solution of storage in the liquid layer flows in the feed flow layer once more, ends when sealing the water level control pipe mouth.This process constantly absorbs nutrient solution with plant and carries out automatically repeatedly.Storage liquid layer (1) is provided with ventilation hole (8) with the junction of feed flow layer (4), is provided with ventilation hole (7) between the upper edge of the alms bowl of planting and evaporation layer.Ventilation hole (8) is ventilated cavitys (6) with interior air with (7) exchange.The alms bowl (5) of planting can freely take out and put into, so that check the situation and the random kind of changing cultivated plant of plant root growth at any time.

Multiple automatic control of the present utility model all utilizes self structure characteristics and material behavior to realize, so principle and uncomplicated, manufacturing is easy to use easily.
