Description

TECHNICAL FIELD

[0001] The utility model relates to field plant cultivation device technical field especially relates to a laser light supplementing device for field crop growth regulation. BACKGROUND

[0002] Improving the yield of staple crops is an important task to ensure national food security and sustainable agricultural development. Modern agricultural technology mainly uses comprehensive methods such as breeding good varieties, establishing precise water and fertilizer utilization models, using intelligent agricultural machinery, and preventing and treating pests and diseases to achieve the yield increase of staple crops. Artificial light source as a light environment regulation light source in facility agriculture can effectively improve the yield of facility fruits and vegetables. Therefore, it is feasible and effective to use artificial light to improve the yield of staple crops in the field. However, due to the short irradiation distance and high energy consumption of traditional artificial light sources, they cannot be widely applied in the field.

[0003] Semiconductor lasers have the advantages of direct electrical pumping, high electrical-optical conversion efficiency, high output power, wide spectral range, low power consumption, and small size. Laser has a wide application prospect in the fields of breeding and seedling raising, crop light supplementing, insect killing and weed control. Among them, field crop light supplementing is a physical light environment regulation method that uses high-power semiconductor lasers as light sources. It is necessary to irradiate laser with appropriate power density to the growth points and leaves of staple crops. The use of the coherence characteristics of laser can improve the light energy utilization efficiency of crops, thereby increasing the accumulation of dry matter of crops and enhancing the stress resistance of crops. This method has the advantages of low power consumption, good yield increase effect, and green environmental protection.

[0004] At present, the existing agricultural light regulation equipment is mainly used for facility agriculture, including mechanical rotating light supplementing lamps, intelligent light supplementing devices based on Internet of Things, and laser light supplementing devices based on light combining elements. The above devices require agricultural Internet of Things, basic power and other supporting conditions, and are more suitable for greenhouse and plant factory application scenarios. Considering that staple crops are mainly planted in open fields, in order to improve the yield and quality of staple crops, a low-cost, easy-to-install and maintain laser light supplementing device is needed to take advantage of the long irradiation distance of laser to realize low-cost light energy supplement and regulation of field staple crops.

[0005] Although the existing agricultural light supplementing lamp has made great progress in improving the light intensity and automation, there are still various problems.

[0006] In the patent application with publication number CN110388596A and the invention name "mechanical rotating light supplementing lamp", a rotating mechanical device is used to drive LED lamps or laser light sources to supplement light energy to the environment. However, the rotating parts have the problems of wear and poor stability, and the high energy consumption of LED lamps also affects the large-scale application of the light supplementing lamp.

[0007] In a patent application with the publication number CN112586241A and the invention name of "Intelligent light supplementing device based on Internet of Things", a communication module is used to associate a light supplementing lamp with an agricultural Internet of Things gateway, so that real-time control of the light supplementing lamp is realized. However, this scheme has high energy consumption and needs support of power cables, resulting in high laying cost and being unable to meet the demand of farmland for low-cost light sources.

[0008] A conventional light supplementing device generally uses a complex mechanical structure or an LED light source, and has problems of high energy consumption, poor stability and high cost, which seriously affect the application prospect of the light supplementing device in large-scale farmland production.

The free-form surface lens array transmits and shapes the laser beam emitted by the laser emitter and emits a rectangular laser beam from the light-transmitting panel. The laser lighting module is fixed at the top of the support column below.

[0013] The solar panel, the energy storage unit and the laser emitter are electrically connected with the control circuit module. The control circuit module is used to control the output power of the laser emitter and the input and output of the solar panel and the energy storage unit.

[0014] Preferably, the light power of the laser lighting module in a single direction is less than 10 watts. The laser emitter is a semiconductor laser, and the emission wavelength range of the semiconductor laser is 400-1000 nm.

[0017] Preferably, the solar panel is provided with at least one, and the power generation capacity is greater than 50 watts.
