What is The Role of Plant Lights in Affecting The Plant Growth Cycle?

图片
In traditional agricultural production, the use of ordinary electric light sources to supplement light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, to change the light environment to regulate the growth and development of plants in the facility cultivation environment. Led plant lights use different measures to avoid different degrees of problems, such as the lack of analysis of specific spectral components leading to impure light quality, inconsistent light intensity, close to or even below the plant's light compensation point, The illumination source has low energy efficiency. A large number of application studies of LEDs in plant facility cultivation environments have shown that LEDs can solve these problems and are particularly suitable for use in artificial light-controlled plant facility cultivation environments. Plants rely on the energy of ligh

How does LED Plant Light Planting Marijuana Fill Light?

Cannabis cultivation: How to grow cannabis with LED plant lights ? The growth and development of cannabis requires an effective accumulated temperature of 2400-3200 °C. Seedlings can withstand a frost of -5-3 ° C, and short-term low temperature will not affect. Marijuana seedlings grow. Cannabis is more than 5 cm below the surface of early spring, and soil temperature is above 8 degrees Celsius. Within 30 days after the emergence of the seedlings, no more irrigation, using LED plant growth lights to promote, can control the development of rooting. According to the difference in the morphology of the female and the male seedlings, the male seedlings can be selected at the time of fixing the seedlings, and the female seedlings can be removed to improve the fiber quality. Seeding the field will choose to leave the female seedlings. The suitable temperature for cannabis growth is 19-23 °C. Hemp plants grow 3-5 cm on average and reach a height of about 10 cm at the peak of growth. At t

LED Plant Light Lighting Features and Advantages

LED plant light features: 1. The effects of different wavelengths of light on plant photosynthesis are different. The light required for photosynthesis in plants has a wavelength of about 400-700 nm. Light from 400-500 nm (blue) and 610-720 nm (red) contribute the most to photosynthesis. 2, blue (470nm) and red (630nm) LEDs, just to provide the light required by the plant, so the ideal choice is to use these two color combinations. In terms of visual effects, the red and blue combination plant lights appear pink. 3, blue light helps plant photosynthesis can promote green leaf growth, protein synthesis, fruit formation; red light can promote plant roots growth, help flowering results and prolong flowering, play a role in increasing yield! 4, LED plant lights red and blue LED ratio is generally between 4:1 - 9:1 is appropriate, usually 6-9:1. 5. When the plant light is used to fill the plant, the height of the blade is generally about 0.5-1 meters, and the continuous irra

Noise Countermeasures for LED Bulbs Using Medium and High Voltage Ceramic Capacitors

图片
Recently, in addition to the requirements of small and thin, energy-saving, and low-noise, electronic equipment is expected to meet the ecological needs of the global warming. Under such market demand, the LED bulbs that have been popular since 2009 have become small and thin, and have achieved high eco-friendship due to their long service life. The electronic components mounted on them are also required to be small and thin. It has a long service life. LED bulbs are equipped with a small power supply with a power of about 10W, mainly using electrolytic capacitors and film capacitors to achieve a smooth function, but the use of small and longer-life ceramic capacitors is also increasing. Ceramic capacitors with higher electrostatic capacity than conventional ceramic materials, this paper will introduce its characteristics, and introduce the recommended circuit for power supply of other electronic devices based on LED bulbs. New material ceramic capacitor performance The proper

Urban Balcony Vegetable Planting Technology

图片
With the rapid development of urbanization in China,  balcony vegetable cultivation has been loved by more and more urban residents. The so-called urban balcony planting mainly refers to the behavior of urban residents using the roof, balcony, window sill, etc. for vegetable cultivation. It not only provides residents with a source of pollution-free vegetables, but also plays a certain role of beautification and greening. 1 Urban balcony vegetable planting Advantage urban balcony vegetable planting not only solves the problem of vegetable purchase of urban residents to a certain extent, but its pollution-free planting method also improves the quality, freshness and nutritional value of vegetables, and provides a guarantee for the safety of urban vegetables. At the same time, the urban balcony vegetable planting is more environmentally friendly, economical and low-carbon, which plays a role in beautifying the balcony and greening the environment, and to some extent, adds idyllic f

How to Plant Beans and Vegetables in Hydroponic System

图片
Beans and vegetables are annual or biennial herbaceous plants of the family Leguminosae , including kidney beans, cowpeas, peas, broad beans, lentils, beans, and ridge beans. Beans and vegetables have high nutritional value and are rich in protein, carbohydrates, fat, calcium, phosphorus, iron and multivitamins. The hydroponic plants cultivated by soilless culture vegetables using this soilless cultivation technique are favored by domestic and foreign flower consumers for their cleanliness, elegant style, strong ornamental, environmental protection and pollution-free. Hydroponic plants should be supplied with liquid during the cultivation process to ensure adequate nutrient supply. The liquid supply time is generally selected during the day and no liquid supply or less liquid supply at night. The number of liquid supply on sunny days is more, and there is less liquid supply in rainy days; when the temperature is high, the light is stronger, and vice versa. Usually, the liquid i
