Walking into the tasting center of Danhe facility vegetable standardized production demonstration park in Shouguang City, Shandong Province, the display area is full of various "strange vegetables and fruits". Tomatoes alone have more than 10 colors, including red, orange, yellow, green, green, white and purple, with different shapes. "The group has cultivated more than 70 vegetable varieties with independent intellectual property rights. Among them, the market recognition of characteristic tomatoes is high. Some varieties outperform foreign seeds, but the price can be about 1 / 3 lower." Said Liu Xinqing, chairman of Shandong Shouguang vegetable seed industry group. Shouguang, known as the "hometown of Chinese vegetables", has long relied on imports of vegetable seeds. "Ten years ago, vegetable farmers needed about 600 million yuan to buy seeds and seedlings every year, of which nearly 400 million yuan was paid to foreign companies. For example, imported tomato seeds cost an average of 800 to 1000 yuan per mu, which is 3 to 5 times that of domestic seeds." Introduction by Liu Xinqing. In order to solve the "bottleneck" problem of seeds, since 2012, Shouguang City has issued a series of support policies for the development of vegetable seed industry, cultivating a number of seed industry enterprises with independent R & D capabilities, including 7 provincial seed industry technology R & D centers and 4 germplasm resource banks. The germplasm resource bank built by Shandong Shouguang vegetable seed industry group can save more than 200000 germplasm resources, and currently 21000 breeding materials are stored. It is the largest vegetable germplasm resource protection center in Shandong Province. "Taking the construction of Weifang national comprehensive experimental zone for agricultural opening and development as an opportunity, we have built and put into operation the R & D center of the national modern vegetable seed industry innovation and entrepreneurship base. We have established in-depth cooperative relations with more than 10 scientific research institutions such as the Chinese Academy of Agricultural Sciences and the China Agricultural University to jointly cultivate improved vegetable varieties." Wang Lixin, director of Shouguang agricultural and rural Bureau, introduced that at present, there are 167 new vegetable varieties independently developed by Shouguang City, and the domestic seed market share has increased from 54% in 2010 to more than 70%. A good seed must be matched with a good law. Zheng Jingqu, 36, took over the "baton" of greenhouse vegetable production from his father. In the Ruihang family farm in sunjiaji sub district, all the vegetable greenhouses are equipped with intelligent electrification equipment. The vegetable farmers are busy raking the soil, making ridges and planting seedlings. Zheng Jingqu took out his mobile phone and tapped it with his fingertip. The water and fertilizer integrated machine "boomed" and the vent on the roof of the shed slowly opened. "In the past, we relied on experience, but now we rely on standards. We set the data of fertilizer application, water supply, temperature and so on in advance. The Internet of things equipment can monitor the growth of crops in all aspects. In case of problems, the system will automatically alarm, and the mobile phone will replace the mobile hoe." Zheng Jingqu said that according to the standard, the output has doubled, and the annual income of a shed is more than 400000 yuan. In recent years, Shouguang City has built modern parks such as Danhe facility vegetable standardized production demonstration park and modern agricultural high-tech test demonstration base, taking the lead in promoting the "six unifications" standardized management of agricultural materials, technology, management, testing, brand and sales, integrating the application of Internet of things, big data, electrification, cloud computing, etc., and promoting automatic temperature control, automatic spraying and drip irrigation, automatic ventilation, automatic fertilization Automatic roller shutter "five automation" technology. "At present, the modern park has radiated more than 80% of the farmers into the era of standardized production, attracting a number of young people like Zheng Jingqu to return to their hometown to start businesses."
