Trees of Ageratum thrive under the illumination of LED plant lights. In an interview with a herbal tea company in Sankeng Town, Qingyuan District, Qingyuan, the reporter recently discovered that the planting base used LED "light formula" to grow medicinal materials, and successfully cultivated seedlings of Noctuid, Dendrobium and Ageratum.
Walking into the greenhouse of the planting base of Qingxin Qiangli Herbal Tea Co., Ltd. in Bengkeng Village, Sankeng Town, rows of LED tubes were installed on the iron frame. The red and blue LED lights exude a soft light, and the Chinese herbal medicine seedlings underneath are growing well. "The growth of plants requires photosynthesis. In a relatively confined space, plants can grow vigorously, which is closely related to these red and blue LED lights." The company's general manager introduced that blue light promotes the synthesis of chlorophyll. The effect is more obvious, the red light promotes flowering and maturity, including the synthesis and conversion of sugar.
It is understood that the wavelength of light required for plant photosynthesis is 400 to 700 nanometers, and the wavelength range is red light and blue light. In May of this year, the base and Fujian Agricultural University conducted school-enterprise cooperation "spectral planting". The LED plant light to promote plant production has invested more than 200,000 yuan to build a greenhouse for cultivating medicinal seedlings. Spectral planting’ can promote the growth rate of seedlings, inhibit some harmful bacteria and pests, and avoid pesticides. For example, it takes four months for Huoxiang seedlings to be cultivated in the field, and it only takes 20 days to cultivate the seedlings through spectrum planting. "According to Pan Yueming, due to the shortened planting cycle of seedlings, pests and diseases can be isolated, the survival rate of seedlings is higher, and the benefits are higher. Take the golden thread lotus as an example, if planted in the field, the lodging rate can reach 30%-40%. With spectral planting, the lodging rate is only about 10%. At present, the base has successfully cultivated seedlings of Anoectochilus, Dendrobium, and Ageratum through spectral planting, and applied them to field planting.
