At present, industrial development, environmental pollution, large-scale fog and haze weather around the country, coupled with rainy and snowy days, lack of sunshine, to the people planting greenhouse vegetables caused a tremendous impact. Vegetable farmers said that after using the plant growth lamp, the plants grew well and made up for the losses. Other plants that did not use the supplementary lamp basically died.

In Hebei, technicians and vegetable farmers told me that cucumbers could be planted in the past few years, but now there are more foggy days, only some plants with short sunshine and low temperature tolerance can be planted. When we went, they said that all the plants that had been planted in the previous batch had died in the long fog and haze. This batch was the second batch. Fortunately, the government bought Jiayue Brand plant growth lamps for them to use. Governments in Lexian, Weixian and Handan of Xiangxingtai City, Hebei Province, have purchased plant growth lamps to subsidize vegetable farmers. The effect is obvious and the loss of long fog and haze days is reduced.
I came to Shouguang and Zibo, Shandong's vegetable city in turn. The local people responded. Now looking up at the sky is hazy. The lack of sunshine has a great impact on plant photosynthesis.
Greenhouse vegetable production has declined significantly. In Yinan, Lanling, Laiwu, Shenxian and Dezhou of Tai'an City, Binzhou City, Shandong Province, the government pays attention to subsidizing vegetable farmers by purchasing Jiayue Brand growth lamps. It plays a certain role in haze days, increasing production and raising prices. Vegetable farmers call Jiayu Brand plant growth lamp "haze supplementary light lamp".
