The invention belongs to the technical field of plant breeding, and specifically discloses a method for raising seedlings of strawberry hydroponic cuttings under an artificial light environment. Strawberry cutting seedlings were rooted in an artificial light environment with a nutrient solution for rooting culture, and the light intensity was 25 μmol / m 2 / s~145μmol / m 2 / s; After the cutting seedlings grow 5-7 adventitious roots of 1.5-2.5 cm, use the nutrient solution for seedling cultivation to carry out seedling cultivation under artificial light environment, and the light intensity is 90 μmol / m 2 / s~270μmol / m 2 / s. The invention utilizes the LED light source to provide suitable light intensity for the strawberry cutting seedlings, promotes the accumulation of photosynthetic products of the cutting seedlings, accelerates the rooting of the cutting seedlings, does not need additional plant growth regulators, and the cutting survival rate can reach 100%.

The invention discloses an illumination device capable of effectively promoting nutritious growing of arabidopsis thaliana, and relates to a plant culturing illumination device. A plant culturing frame, neutral light fluorescent light tubes, neutral light fluorescent light frames, UV-B light tubes, UV-B light frames, a planting box, a timer and a thermometer. Four layers of the planting culturingframe is arranged, the size of the planting culturing frame is adjusted according to the floor occupation area of a cultured plant; the neutral light fluorescent light tubes are arranged on the neutral light fluorescent light frames, the UV-B light tubes are arranged on the UV-B light frames, the neutral light fluorescent light frames are arranged on the tops of each layer of the plant culture frame, the UV-B light frames are arranged at the bottoms of the neutral light fluorescent light frames, and the neutral light fluorescent light tubes and the UV-B light tubes are independently controlledby the timer to provide different light sources for the growing of the arabidopsis thaliana; the thermometer is arranged on the side face of the plant culturing frame, the plant culturing box is arranged on the plant culturing frame and used for planting the arabidopsis thaliana, and therefore the arabidopsis thaliana is allowed to be in a certain nutritious environment.

The invention discloses a light intensity adjustment method, device and system for a front windshield, the front windshield and an automobile. The front windshield is divided into a plurality of regions, the light transmittance of each region is adjusted according to the intensity of light entering the human eyes through the region and a preset light intensity acceptance range, and therefore it can be ensured that the intensity of the light entering the human eyes through each region is a suitable light intensity so that a driver can drive under the comfortable light intensity, the dazzling strong light is avoided, and the partial darkness caused by strong light shielding is also avoided.

The invention provides a method for planting spinach in summer and a special light-dispersing cooling and thermal radiation protective screen for the method. The method for planting spinach in summer includes the steps of greenhouse building, protective screen covering and continuous cropping obstacle prevention. According to the method, a greenhouse arch frame is covered with the protective screen, light intensity in a spinach planting greenhouse is 48 klux, and the shading rate is 50-60%. Greenhouse building includes the steps that the greenhouse is built, a longitudinal ventilation port is formed in the top of the greenhouse, and a plastic film at the front end of the greenhouse is uplifted by 1 m. Continuous cropping obstacle prevention includes the steps that soil is turned up and irrigated with ozone water with the mass concentration being 70%, the soil is sealed for one week, and air exhaust is conducted. By means of the method, the quality of summer spinach is obviously improved, the yield of the summer spinach is obviously increased, the disease and insect pest occurrence rate of the summer spinach is lowered, and the low-temperature environment and proper light can be provided for growth of the summer spinach.

The invention discloses a symbiotic cultivation method of ganoderma lucidum and mountain rice. This method realizes the symbiotic cultivation of Ganoderma lucidum and mountain rice by interplanting Ganoderma lucidum in mountain rice, and obtains high-quality Ganoderma lucidum and mountain rice, which provides a new way for field cultivation of Ganoderma lucidum and improves the land utilization rate of mountain rice planting . Mountain rice plants are generally more than 1 meter long, with upright stems and loosely distributed leaves upward. With a reasonable plant-to-row spacing, the environment under the mountain rice plants can form a microclimate suitable for the growth of Ganoderma lucidum, providing suitable growth temperature, humidity and light intensity for Ganoderma lucidum There is no need to build arch sheds or sunshades, etc. The soil in the upland rice planting area is also more suitable for the growth of Ganoderma lucidum under the influence of upland rice microclimate; co-cultivation of ganoderma in the upland rice, the upland rice and the ganoderma have a synergistic growth effect, and the quality of the ganoderma is excellent and The shape is relatively regular, and more than 90% of the caps are kidney-shaped, semi-circular or nearly circular, and the yield of mountain rice can be increased by more than 15% per mu.
