With sensors installed in farmland, relying on one platform and eight systems, staff can realize online, visual and intelligent management of farmland production scenes.

　　"To scale to benefit, to brand to development, to digital to breakthrough." Qiu Fei, deputy head of Binhai County, said that the current efforts are being made to do a good job of spring farming and prevention and control of the epidemic. The next stage will be to build a thousand mu digital farm, introduce "central kitchen +" to integrate agricultural industry chain, strengthen the introduction of rural e-commerce, and develop new forms of business such as order agriculture.

　　Insect lamp, soil moisture station, spore capture instrument, water and fertilizer integrated machine...... There are many equipment in the Blueberry and blackberry Industrial Demonstration park in Nanjing National Agricultural High Zone. When you open the digital farm platform on your mobile phone, you can see the planting tips. "This is peak blueberry season, so pest control and fertilizer treatment are needed. With the integrated drip irrigation system of water and fertilizer, 200 mu of water can be irrigated in one and a half hours." Technical personnel introduction.

　　The technical staff of provincial agricultural technology extension station suggested that the current crop in Jiangsu province is in the rapid growth stage of wheat jointing stage and rape flowering stage, which is the key period to strengthen fertilizer and water management and build a high yield shelf. All localities should promptly sow spring crops such as soybeans, peanuts and corn, and demonstrate in advance the application of strip planting of soybeans and corn. Turn over the rice seedling breeding pond in time, do a good job in fertilizing bed soil, disinfection and sterilization preparation work.

　　Complete the "hard task" and carry the "oil bottle"

　　This year, the Ministry of Agriculture and Rural Affairs implemented the expansion of soybean oil seed in the country, mainly promoted the strip compound planting technology of soybean and corn, and issued the promotion task of 3.092 million mu of soybean sown area and 600,000 mu of strip compound planting area of soybean and corn in Jiangsu Province. General Office of the provincial government recently issued special promotion work plan, provincial department of agriculture and rural areas issued technical guidance. Spring ploughing period, from the provincial level to all parts of the deployment and promotion.

　　Province agriculture and rural areas planting management office director Du Yonglin hall, soybean corn belt compound cultivation, is the use of the advantages of soybeans and corn in the same growing season, change the single planting corn or soybean to high stalk crops of corn and stem the compound planting crop soybeans, corn belt of the general planting 2 line to line 2-6 alternate planting soybean belt. Compare two separate planting, each mu can increase the soybean 100-150 kilograms.

　　Jiangsu province respects the wishes of farmers, and is studying and exploring suitable and practical planting patterns, focusing on the promotion and application in Huaibei, coastal areas and along the Yangtze River.
