Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that although functional block divisions are provided in the system drawings and logical orders are shown in the flowcharts, in some cases, the steps shown and described may be performed in different orders than the block divisions in the systems or in the flowcharts. The terms first, second and the like in the description and in the claims, and the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In a first aspect, referring to fig. 1, fig. 1 is a flow chart of steps of an understreel lighting control method.
Provided is an under-tree lighting control method, including:
step 1, connecting a light supplementing lamp for supplementing light to plants under trees;
step 2, obtaining the real-time photosynthetic rate of the under-tree plant;
step 3, acquiring a photosynthetic rate threshold;
and 4, adjusting the luminous flux emitted by the light supplement lamp to enable the real-time photosynthetic rate of the plants under the tree to be adapted to the photosynthetic rate threshold value.
The term "under-tree plant" refers to a plant in the shade of a tree.
In step 1, the fill light fixture is set to emit light flux that can act on the plants under the tree. And to give light to the understory plants. The wavelength range of the light emitted by the supplementary lighting lamp is 400nm to 700 nm. In this wavelength range, the photosynthetic activity of the plant is highest. And for the connection of the light supplement lamp, the fingers are connected with the light supplement lamp in an electric connection mode. The connection of the light supplement lamp has the effect of controlling the light supplement lamp in real time, so that the luminous flux emitted by the light supplement lamp can be adjusted in real time.
The step 1 is used for establishing a connection with the light supplement lamp, so that the light supplement lamp can be controlled in real time to adjust luminous flux emitted by the light supplement lamp.
In step 2, the real-time photosynthetic rate of the plants under the tree is obtained. The real-time photosynthetic rate of the plants under the tree can be obtained through the photosynthetic rate obtaining instrument. The photosynthetic rate refers to the rate at which a plant undergoes photosynthesis. The real-time photosynthetic rate of the under-tree plant is mainly a rate of evaluation of photosynthesis of the under-tree plant.
The effect in step 3 is to obtain a photosynthetic rate threshold, wherein the photosynthetic rate threshold can be set in advance through testing. These set photosynthetic rate thresholds can be obtained by means of a look-up table.
And 4, adjusting the supplementary lighting lamp. The controller can be used for connecting the light supplement lamp, and then controlling the luminous flux emitted by the light supplement lamp. And determining the magnitude of luminous flux emitted by the light supplement lamp through the real-time photosynthetic rate of the plants under the tree. It is necessary to ensure that the real-time photosynthetic rate of the plants under the tree is adapted to the photosynthetic rate threshold. By adaptive is meant that the real-time photosynthetic rate is in a constant proportional relationship with the photosynthetic rate. In some embodiments, the fixed ratio between the real-time photosynthetic rate and the photosynthetic rate threshold is 1 to 1. That is, the real-time photosynthetic rate of the under-tree plant is equal to the photosynthetic rate threshold. The light flux emitted by the light supplement lamp is adjusted to ensure that the photosynthesis of the plants under the tree is the same as the expected photosynthesis. So that the under-tree plants are not influenced by tree shade and can still grow according to a determined rate.
In some preferred embodiments, the determination of the threshold photosynthetic rate is derived from an open-air plant. For horticulture, it is generally required that the under-tree plants and the open air plants maintain a certain growth rate. By open-air plants are meant plants which are open-air, i.e. plants which are not shaded, and for which no additional supplementary lighting is required. If simply carry out the light filling to under-tree plant, will cause under-tree plant growth rate too fast like this to lead to holistic horticulture molding to receive the influence. Therefore, there is a need to maintain the synchronized growth of the understreble plants and the open air plants. For this purpose, the real-time photosynthetic rate of the open-air plants is taken as the photosynthetic rate threshold.
The benefits of using the real-time photosynthetic rate of an open-air plant as the photosynthetic rate threshold are: the real-time photosynthetic rate of the plants under the tree is ensured to be adapted to the photosynthetic rate threshold value by adjusting the luminous flux emitted by the light supplementing lamp. Therefore, the real-time photosynthetic rate of the open-air plants is used as the photosynthetic rate threshold value, so that the growth rates of the under-tree plants and the open-air plants can be synchronized.
For the method for acquiring the real-time photosynthetic rate of the open-air plant, in some preferred embodiments, the method for acquiring the real-time photosynthetic rate of the open-air plant comprises the following steps: acquiring the carbon dioxide concentration of the environment where the open-air plant is located in real time, acquiring a first potential maximum photosynthetic rate according to the carbon dioxide concentration, and recording the first potential maximum photosynthetic rate as a first potential maximum photosynthetic rate;
acquiring photosynthetic photon flux density of the open-air plants in real time to obtain first photosynthetic photon flux density, and calculating the real-time photosynthetic rate of the open-air plants according to the first potential maximum photosynthetic rate and the first photosynthetic photon flux density;
