The shadowless light bulb use one main bulb + three spare bulb, divided into multiple independent illuminant group; every OT lamp use double CPU control, every group of LED illuminant controlled by special circuit chip, any group failure will not affect the normal use of shadowless light.
Use international advanced warm white LED as shadowless illuminant, environmental, lower energy consumption LED bulb, bulb life: ≥60000 hours
The handle on the central of operation lamp can be detachable, can take high temperature (134°C) sterilization treatment, easily adjust, flexible fixed; there is control panel located in the big and small C arm joint, with brightness tips.

Problems to pay attention to when applying fertilization outside roots
1. The time for moistening the leaves should be as long as possible. After the roots are sprayed, the longer the leaves are moistened, the more nutrients the plants can absorb. Generally, after 4 o'clock in the afternoon, or before 9 o'clock in the morning, spraying is better. The strong sun and strong wind and rain at noon are not suitable. 2, the solution should be fully adhered to the leaves generally use the better performance of the sprayer, can also be mixed with a small amount of wetting agent or detergent to promote nutrient penetration into the leaves. 3, the concentration should be appropriate to a variety of crops can tolerate the concentration is different, the general cereal crops can be thicker, beans, fruit trees, etc. can be more thin. The solution concentration of a large number of nutrient elements is generally about 0.2% -2%, and the solution of trace elements is approximately 0.01% - 0.1%. 4. The pH of the nutrient solution to be applied to the roots of moderate and moderate pH is generally close to neutral, and overacidity is not conducive to crop absorption of nutrients. 5, the solution to be sprayed on the back of the leaves on the back of the crop more stomata, looser tissue, nutrients easily infiltrated, and the back of the solution dry slow, such as cereal crops can also be sprayed on both sides, because there are a lot of leaf stomata. If boron, calcium, iron, manganese, molybdenum, and zinc are sprayed, they are generally sprayed on new shoots. 6, can not replace soil Fertilizer crops outside the root absorption of nutrients is very small, can not fully use root fertilization in place of soil rhizosphere fertilization, especially a large number of nutrients, should be the main soil fertilization, root fertilization as a combination of auxiliary methods .
