Abstract
A plant phototropism guiding device relates to a teaching aid, and comprises an early-stage shading box, a later-stage shading box, an intermediate clapboard, a plant growth hole, an early-stage light guide hole, a later-stage light guide hole, a leguminous plant seedling, a flowerpot, the box body supports and a pedestal. The box body supports are arranged on the pedestal, the upper ends of the box body supports are equipped with a shading box, and the shading box is divided into the early-stage shading box and the later-stage shading box by the intermediate clapboard in an inner cavity of the shading box. The early-stage light guide hole is arranged in the center of the intermediate clapboard, and the later-stage light guide hole is arranged on the box body outside the later-stage shading box. The plant growth hole is arranged in the middle of a bottom plate of the early-stage shading box, the flowerpot is arranged below the plant growth hole, and the leguminous plant seedling planted in the flowerpot penetrates the plant growth hole to extend towards the inner cavity of the early-stage shading box. The plant phototropism guiding device enables the phototropic characteristic of the plant growth to be understood really via the real object demonstration. The students can see the characteristic of the plant phototropic growth obviously by using the device to cultivate the leguminous plant seedling.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a Plants to light directing arrangement.
Background technology
In Biology Teaching, the phototropism of plant is generally that teacher tells about to the principle of light with to the phenomenon of light.Be not easy to allow student see real to optical phenomenon.By this device, can allow student come to understand at once, because the ability of the searching light of plant is too magical.There is plant can greatly improve teaching efficiency to light directing arrangement, also greatly increased student's learning interest.
Summary of the invention
The purpose of this utility model is to provide a Plants to light directing arrangement, and this plant can see through visual illustration to light directing arrangement and get a real idea of the characteristic of plant growth to light.With this device, cultivate fabaceous seedling, can allow student see that obvious plant is to the long characteristic of photoproduction.
The purpose of this utility model is achieved through the following technical solutions:
One Plants is to light directing arrangement, and described device comprises shading in early stage case, later stage shading case, central dividing plate, plant growth hole, early stage light lead hole, later stage light lead hole, legume seedling, flowerpot, antinose-dive leg and base; On base, be equipped with antinose-dive leg, the upper end of antinose-dive leg is equipped with shading case, shading box cavity has a central dividing plate that shading case is divided into shading case and later stage shading case in earlier stage, central dividing plate middle position is established light lead hole in early stage, the outer side box body of later stage shading case is provided with later stage light lead hole, in the middle of the base plate of shading in early stage case, be provided with plant growth hole, put a flowerpot below plant growth hole, the legume seedling of planting on flowerpot sees through this plant growth hole and stretches to shading in early stage box cavity.
Advantage of the present utility model and effect are:
This plant can see through visual illustration to light directing arrangement and get a real idea of the characteristic of plant growth to light.With this device, cultivate fabaceous seedling, can allow student see that obvious plant is to the long characteristic of photoproduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that legume seedling is grown in shading case.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
In figure, parts are numbered: 1. early stage shading case; 2. later stage shading case; 3. central dividing plate; 4. plant growth hole; Early stage light lead hole; 6. later stage light lead hole; 7. legume seedling; 8. flowerpot; 9. antinose-dive leg; 10. base.
This plant comprises shading case 1 in early stage, later stage shading case case 2, central dividing plate 3, plant growth hole 4, early stage light lead hole 5, later stage light lead hole 6, legume seedling 7, flowerpot 8, antinose-dive leg 9 and base 10 to light directing arrangement.On base 10, be equipped with antinose-dive leg 9, the upper end of antinose-dive leg 9 is equipped with shading case, shading box cavity has a central dividing plate 3 that shading case is divided into shading case 1 and later stage shading case 2 in earlier stage, central dividing plate 3 middle positions establish one early stage light lead hole 5, the outer side box body of later stage shading case 2 is provided with later stage light lead hole 6, in the middle of the base plate of shading in early stage case 1, be provided with plant growth hole 4, below plant growth hole 4, put a flowerpot 8, on flowerpot 8, legume 7 seedlings of plantation stretch to shading in early stage case 1 inner chamber through this plant growth hole 4.Fig. 2 is the schematic diagram that legume seedling is grown in shading case, as seen from the figure, legume seedling 7 through early stage light lead hole 5 and later stage light lead hole 6 stretch to the outside of shading case, student, by demonstration of the present utility model, can understand plant growth visually to the characteristic of light.
During teaching demonstration, in shading case, made shading treatment, light can only see through later stage light lead hole and early stage light lead hole enter shading case, due to the characteristic of plant growth to light, we can see that the legume seedling of planting on flowerpot is inclined to the trend of light lead hole growth in shading case, and student sees through visual illustration and got a real idea of the characteristic of plant growth to light.
