LED lamp "light formula" medicinal materials bring more benefits

Patchouli grows vigorously under the irradiation of LED plant growth lamp. In a recent interview with a herbal tea enterprise in the three pit town of Qingxin District, the reporter found that the planting base used LED "light formula" medicinal materials, and successfully cultivated the seedlings of Lindera, Dendrobium and agropyum. Walk into the greenhouse of the fresh and strong Herbal Tea Co., Ltd. located in the collapse pit of the three pit town, and install a row of LED lights on the iron frame. The red and blue LED lamps emit soft light, and the seedlings of Chinese herbs grow well below. "The growth of plants requires photosynthesis. In relatively confined spaces, plants grow vigorously, and are closely related to these red and blue LED lights." Pan Yueming, general manager of the company, said that the effect of blue light on chlorophyll synthesis is obvious. Red light promotes flowering and maturation, including the conversion of sugar. It is understood that photosynthesis of plants needs wavelength of 400 to 700 nm, in this wavelength is red and blue light. In May of this year, the base and the Kasetsart University in Fujian carried out "spectrum planting" in school enterprise cooperation, studied LED lamps that could promote plant production, invested about 200000 yuan, and built greenhouse for cultivation. Medicinal herbs and seedlings. "Spectral planting" can promote the growth rate of seedlings, inhibit some bacteria and pests that are harmful to seedlings, and avoid pesticides. It takes four months for the seedlings to grow in the field, and only twenty days to grow seedlings by spectral planting. According to Pan Yueming, because of the shortening of the planting cycle and the isolation of pests and diseases, the survival rate of seedlings is higher and the yield is higher. For example, the lodging rate is 30% - 40%, and the lodging rate is only about 10% through spectral planting. At present, the base has successfully cultivated the seedlings of Lindera, Dendrobium and Agrobacterium by spectral planting, and has been planted in the field.
