Field head “new agricultural tide” : cultivate soil first, agricultural production paste “ID card”

Taizhou April 6 (reporter Fan Yubin) “every day there are tons of water bamboo shoots sent to Jiangsu, Zhejiang and Shanghai, each box of water bamboo are affixed with the two-dimensional code, this is the ‘ID card’ of water bamboo shoots, but also the ‘pass’ to enter the market.” Jiang Liangzhen, a rice cane farmer who has been growing water bamboo for 13 years in Beiyang Town, Huangyan District, Taizhou City, Zhejiang Province, never imagined that his own water bamboo would one day benefit from the new technology.

At the beginning of the 14th Five-Year Plan, the clarion has been sounded to comprehensively promote rural revitalization. How China, a big agricultural country, steps toward becoming a strong agricultural country, and how to improve agricultural quality, efficiency and competitiveness is an important topic.

Now, in the digital economy big province, birthplace of the idea of “green water castle peak is the jinshan yinshan” – zhejiang fields, digital, ecology, agricultural technical area management model arises at the historic moment, local farmers are leading more wisdom, more healthy, more efficient agriculture “new trend”, thus boosting rural industries.

Witness “Technology Changes Agriculture” from “One Yard”

“We will record all aspects of sowing, fertilizing, harvesting, packaging and sales through the ‘Honest Farmer’ App on our phones, so that dealers and consumers can feel at ease with our fingers. We farmers will certainly be happy.” Jiang Liangzhen, head of Huangyan Guanao water bamboo cooperative, said that the traceability of the quality and safety of agricultural products not only did not increase the cost, but made Beiyang water water bamboo more salable.

Huangyan, where it is located, is one of the first units to build the quality and safety traceability system for agricultural products in Zhejiang Province. Agricultural product safety is the earliest field of local agriculture with the help of digital empowerment, and now it has realized the whole-yard supervision from “field head to tongue”.

In the 13 years since large-scale cultivation of water cane, Jiang Liangzhen has seen how technology has changed agriculture. She cites the process of growing water cane seedlings as an example. “Under the guidance of agricultural experts, we are trying to grow double crop water bamboo shoots with moss tube, which has greatly reduced the time and cost of growing seedlings.”

In practice, jiangliangzhen improved the yield and quality by purifying and strengthening introduced water bamboo varieties several times, solved the problem of winter heat preservation by using the film covering technology of the ring shed, and controlled the growth and maturity period of water slurry and fertilizer rationally. In addition, straw recycling, insecticide lamps, sex attractant and other green prevention and control equipment and technology, strengthen field production supervision and product quality monitoring.

It is not difficult to see from the change of water bamboo field, “technology changes agriculture” is not a slogan, Zhejiang agriculture is more affected. According to the measurement method released by the Chinese Academy of Agricultural Sciences, the contribution rate of agricultural science and technology progress in Zhejiang has reached 65.15%.

As farmers accelerate to embrace the benefits of technology, governments are pushing the handle.

Integrated innovation and iterative upgrading are the development direction of agricultural digitalization. For example, Jinhua has developed the intelligent service system of “one thing in the field”, which centers on the four links of “planting, management, harvesting and marketing” in the whole cycle of field planting to realize checklist-type management, one-stop management and integrated service, making modern agricultural service “accessible at one point” and becoming a good helper for farmers in field management. Huangyan, “the hometown of mandarin oranges in China”, has recently launched the information service platform of “A Map of Smart Orchard”, which has connected various agriculture-related management data platforms, providing symmetric information and digital support of “A Map” for citrus production…

Science and technology support the development of modern agriculture. Data show that during the “13th Five-Year Plan” period, Zhejiang has implemented 158 agricultural science and technology cooperation projects of “three parties, farmers and six parties”, 1084 projects of industrial technical team, and 20 major scientific and technological achievements of innovation, integration and demonstration…

Perspective on the way of agricultural ecologicalization from “healthy soil”

Spring ploughing and sowing season, into the Huangyan Zhongde farm, the reporter found that many fields did not rush to plant crops. From a distance, the fields covered with green manure such as vetch vetch and vetch vetch look like “wasteland”.

The farm’s founder, Li Jinbo, told reporters: “To plant good land, we must first raise good soil. Only healthy soil can grow healthy crops.”

Eliminate the use of chemical fertilizers and pesticides. This is Li Jinbo’s rule of thumb for organic farming. He started growing organic food and vegetables in Huangyan eight years ago, after being inspired by an organic farm in Germany.

Can yield be guaranteed without chemical fertilizer? Without pesticides, how to prevent and control pests and diseases? To this end, Li Jinbo began to practice after learning Demeter Dynamic Farming, which originated in Australia.

“Grass feeding cattle, green manure returning to the field, rice brewing, rice bran feeding poultry, manure composting… After 7 years of transformation, the farm has established an independent ecological circulation system.” Li Jinbo said that practice has found that healthy crops do not attract insects, and more than 35 species of birds have been attracted to more than 300 mu of land. Since 2015, Sino-German agricultural products have successively passed the China Organic Certification, the European Union Organic Certification and the Australian Active Farming Certification.

In the economically developed regions of eastern China, organic agricultural products are more recognized by the market. At the same time, Li Jinbo said: “The most gratifying thing for me is the impact and change the farm has brought to the surrounding villagers.”

Li Jinbo, in fact, the practice of digital agriculture is not at odds with zhejiang pushing, scenes of ecological circular agriculture in zhejiang earth already everywhere: from the “sang ii fishpond” in the north of the lake, to the mountains of southern of qingtian “symbiosis” rice fish, lotus “lotus symbiosis” duck, celebrating “mushroom produced Lin”, to the west zhejiang quzhou qu jiang of livestock and poultry waste recycling use… Only by ensuring that agriculture is the top priority can the people eat healthier and feel at ease.

“Plant factories” revolutionize traditional agriculture

The superposition effect of “digital + agriculture” is on the rise in Zhejiang. Throughout the practice of various places, the “plant factory” agricultural production mode has changed the “dirty, tired and bitter” of traditional agriculture, and attracted more people to join agriculture and enjoy it.

Walking into the Zhejiang Provincial Digital Agricultural Factory Pilot Demonstration and Zhejiang Provincial High-quality Green Science and Technology Demonstration Base — Taizhou Xihe Farm, the reporter found that the farm covers an area of more than 600 mu, only a few people are farming, most of the farm work is handed over to machinery and automation facilities. In the planting greenhouses, the monitoring system detects the production environment and crop growth conditions in real time, and automatically regulates through film rolling and sprinkler irrigation systems.

“The farm grows more than 100 kinds of vegetables throughout the year. We adopt crop rotation, intercropping and intercropping, which not only enrich agricultural products, but also improve land use efficiency and reduce the impact of pests and diseases.” Zhang Yongfeng, deputy general manager of Taizhou Xihe Ecological Agriculture Development Co., Ltd., said the farm also introduced rotary tillers, fertilizer spilling machines, ridging machines and ditching machines, which improved the efficiency of farmland by three or four times.

Green prevention and control of diseases and insect pests is also the feature of “Plant Factory”. Through solar insecticide lamps, yellow panels and sexual traps, the species and quantity of insects captured are recorded regularly to monitor the insect pests, carry out insect monitoring and early warning, and timely carry out pest control according to the monitoring results.

These days, growing pepper and tomato plants are showing up with aphids, and farm technicians are busy placing harlequin ladybird eggs on the plants. “The harlequin ladybird is a natural predator for aphids. The biological control of harlequin, which is a pest control, is effective quickly and reduces the use of chemical pesticides.” Huangyan agricultural rural bureau technical instructor Tao Yonggang said.

Not only is the agricultural planting field, the breeding field also accelerates the embrace digitalization.

In Huzhou Nanxun and Yangdong Village of Fuzhen Town, the 24-hour real-time monitoring platform of the Internet of Things enables farmers who used to rely on experience and even “patrol the ponds all night and stay up all night” to “raise fish while lying in bed” by remote control 24 hours a day.

In Ningbo Cixi National Modern Agricultural Industrial Park, Cixi Zhengda Egg Industry Co., Ltd. realized the intelligent scene of modern laying hens breeding “leaving the land and living in the factory”. Within the 400 mu breeding area, there are 3 small buildings with 250 thousand chickens and 9 chicken houses with a capacity of 750 thousand layers. The whole process of production and breeding of 1 million laying hens and the whole industrial chain are digitalized and controlled. Each breeding engineer can easily manage 86,000 chickens…

Digital transformation is not just about planting and breeding. Many agricultural bases live broadcast and broadcast field images online in real time, combine with innovative marketing methods, and use self-built online shopping malls to sell, reducing circulation links and realizing the transfer of agricultural products from “the field to the table”.

Taking digital agriculture as an example to guide production, supply and marketing, Hangzhou Yuhang Yongan Daoxiang Town realizes the digital adoption of rice fields, digital agricultural tracing, digital cultural tourism map guide, VLOG intelligent short video, visual sales, etc., making modern agriculture “beautiful and fun”.

It is not difficult to find that digital enabling agriculture has penetrated into each link of Zhejiang agriculture. Talk about future trends, agriculture and rural areas in zhejiang province party secretary, director wang tong Lin said that zhejiang will accelerate the new technology, new equipment, new achievements in the countryside, promote grain production function area, modern agricultural parks, characteristic agriculture strong town, raising base of digital transformation, scientific guidance to guide farmers farming, ecological farming, efficient farming, planting and raising brand, make green development in zhejiang province agriculture and rural areas of the new normal.

The transformation from the assembly line, high efficiency and ecological planting that used to be “mud on two feet” to “plant factory” has been accompanied by the iterative update of 5G, artificial intelligence, Internet of Things and other new technologies, making farming more and more easy for farmers and making the future path of rural revitalization more clear.
