Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
The present invention is achieved by the following technical solutions, comprising: layer stereo growing frame, water storage tray, cave dish, back pool, inlet pipeline, water return pipeline and control hardware and software.Below be described respectively:
(1) layer stereo growing frame
Primary study of the present invention growing frame parameter, enables lower floor's illumination reasonable layout; Individual layer, can according to the plant height of different vegetable and the reasonable disposition of the demand of illumination being carried out to multilayer apart from adjustable.
According to the demand of plant growth to illumination, growing frame width can not be too wide, too wide upper strata crop will block the illumination of lower floor crop, show that the optimization overall dimensions of layer stereo growing frame is by setting up three-dimensional crop illumination mathematical model: length × wide × height=2 × 0.6 × 1.35m, be divided into upper, middle and lower three layers, every interlamellar spacing 0.5 meter, often arrange the spacing 1.1 meters of growing frame, experiment in cultivation through multiple batches of green vegetable is verified this parameter, the reasonable layout of growing frame lower floor illumination can be realized, meet different habit of growth crop to the demand of illumination.
The number of plies of this growing frame can increase according to production requirement, is not limited only to 3 layers described in this example.
Meanwhile, growing frame different aspects determine being configured to of vegetables, and top layer selects happiness light vegetables: Chinese little greens, romaine lettuce and water spinach, and the second layer can select more resistance to cloudy kind: Lettuce, intensive shadow on lung, celery and spinach; Third layer selects resistance to cloudy kind: curled mallow, crowndaisy chrysanthemum, rice amaranth, harmony dish.Every layer can regulate according to the plant height of vegetable species.
For the greenhouse of 32 meters long, put 4 rows, row and row 1 meter, interval, often arrange 12 growing frames; Layout is as Fig. 5.Therefore growing frame number is: 12 × 4=48.
