Plants fill light varieties and price
Light is the use of artificial light to create a good environment for the light plant, at present at home and abroad more artificial light source is a high pressure sodium lamp, it has the advantages of high intensity, broad chromatogram, but there is also a large power consumption, light conversion efficiency. Special lights have to use less energy in the current energy shortage is more and more times, at home has been promoting the use of plant growth is more light, it is light, a fluorescent light is energy saving, emission spectrum and according to the required plant scientific collocation. At present, there are mainly two kinds of widely used, is blue and red light for plant growth, photosynthesis, photosynthesis of red and blue light is two visible light efficiency is the highest, with the two light source, the power consumption in the same circumstances, can achieve better effect, that is to say the light conversion efficiency the earth is increasing. But there are also inconvenient installation, lamp holder and hydroscopic short circuit fault, in this kind of situation at home and abroad and the emergence of a most advanced and new lights is a semiconductor diode is also called LED, the first light it is cold light exothermic, it also can send out the required special spectrum the more valuable is that it is a DC power supply, convenient installation, is not afraid of wet environment, and its power consumption is ordinary lights 1/8, is the most energy saving and efficiency of light is the highest, the foreign technology in plant factory has been a large area to use, and the application in China is just start.
At present, agricultural production, especially in the protected cultivation, cultivation of light has been more and more attention, through the implementation of the anti Ji Zaipei light, improving the yield and quality of the light, the light through the light to break dormancy and to foster a special effect. In the process of micropropagation of plants, the use of light is more efficient, because it is produced in a highly intensive environment, better than the light efficiency of cultivation, even a larger increase in the cost, but still very cost-effective, so the light has become an agricultural technology rapid propagation in factory will be less the.
In the selection of light source, you can install operations before installation must be shed for each installation quantity and power and strength to understand, generally used for fast breeding seedling light intensity above 1000LX, the spectrum to 5:1~10:1 with blue and red light is good. According to a 40 Watt lamp for plant growth, generally every 3 square meters to install a lamp, a standard greenhouse seedbed available area of about 180 square meters, according to this calculation, a fast propagation base 8 meters by 30 meters standard in the installation of 40 Watt plant growth light 60 the total power of 2400 watts. And if the light diode technology can achieve more energy saving, may choose a try. In general a standard greenhouse lighting to achieve this effect, only 3000 super strength of the light emitting diode can, with each 0.1 watts of calculation, the total power of 300 watts, the power consumption of only a plant growth lamp1/8, and the DC power supply, but also more installation. Now many places have begun to use light diode light source to replace the traditional. After calculating and planning the installation quantity of each greenhouse, the uniform layout construction can be carried out.
