<\/figure>\n\n\n\n35 days to harvest a crop of lettuce<\/strong>50 times more productive than open air<\/strong><\/p>\n\n\n\n \u3000\u3000Into the lettuce planting area, six layers of cultivation racks neatly arranged, like a three-dimensional \"green workshop\".The roots of each lettuce plant are rooted in biodegradable sponges, drinking a precisely proportioned nutrient solution; overhead, special LED lights shine on demand, day and night.<\/em><\/p>\n\n\n\n \u3000\"When you grow lettuce in a big field, it usually takes 60 days to harvest it, and here we can market it in 35 days.\" Xu Guijun, head of agricultural technology at Shenneng Nanjing Energy Holding Co.By precisely regulating light, temperature and humidity, the lettuce growth cycle has been shortened by nearly 20 days.<\/em><\/p>\n\n\n\n The improvement in efficiency goes far beyond that. Xu Guijun said the plant factory's lettuce utilization rate exceeds 95%, compared to only 60%-70% for traditional fields;Three-dimensional planting allows the yield per unit area to be more than 50 times higher than that of a large field, with only one-fifth the amount of labor used.<\/em><\/p>\n\n\n\n Currently, this plant supplies about 100 kilograms of lettuce per day, up to 240 kilograms at full production.Lettuce picking directly after loading, to achieve \"half-day delivery\", mainly sold to Shanghai, Nanjing and other neighboring cities.<\/em><\/p>\n\n\n\n Hornwort that is afraid of high temperatures<\/strong>It blooms here in all seasons.<\/strong><\/p>\n\n\n\n \u3000\u3000Neighboring the lettuce is a patch of colorful hornbeams.<\/p>\n\n\n\n \"We now grow 12 varieties, all of which are customized.\" Xu Guijun said it takes about two months from seedling to flower, with a flowering period of up to four months, and a single plant can produce more than 200 flowers, with a daily output of more than 100,000 flowers.<\/p>\n\n\n\n Gladiolus is afraid of high temperature, the field can not be planted in the summer, but this is precisely the plant factory's \"high time\". \"Outside the summer planting can not come out, the hotel's dish decoration but can not do without them, so the summer is our distribution peak.\" Xu Guijun introduction, at presentThe average daily delivery of Jiaozuo is about 3,000 flowers, and 15,000 flowers are delivered in a day at the peak, mainly supplying hotels in Shanghai and surrounding cities.<\/em><\/p>\n\n\n\n On-board green power generation<\/strong>Growing greens under the board<\/strong><\/p>\n\n\n\n \u3000\u3000This plant factory, which covers an area of 1,100 square meters, is permeated with a sense of technology everywhere. Temperature, humidity, light and other parameters are precisely regulated, and different spectra are set for plants in different growth periods to realize uninterrupted production throughout the year. The biodegradable sponge substrate and medical-grade nutrient solution are tested by EU SGS.No pesticide residues and heavy metals, meets the standard of no-wash and can be eaten directly.<\/em><\/p>\n\n\n\n The biggest highlight is on the roof. Solar panels have been laid above the plant, creating an \"agro-photovoltaic complementary\" model - theGreen power generation on the boards and green planting under the boards.<\/em><\/p>\n\n\n\n \u3000\u3000\"Solar power for the plant plant energy supply, photovoltaic panels can generate more than 24 million degrees a year, while the plant plant annual electricity consumption of only three or four hundred thousand degrees.\" Xu Guijun said, the residual power on the Internet, both to provide clean energy, but also to realize the \"power generation on the board, under the board planting vegetables\" double income. With the support of science and technology, the annual output value of this plant can reach 1.5 million yuan. \"In the future, we want to continue to develop the market and make sustainable development go further.\"<\/p>\n\n\n\n <\/p>","protected":false},"excerpt":{"rendered":" Right now is the key time to prepare for spring plowing.
