3月23日，The Bureau of Industrial Information Technology organized the provincial science and technology special commissioner of the College of Resources and Environment of Northeast Agricultural University, Mr. Zhang Di, Mr. Liu Huajing, Mr. Li Wei, and Mr. Zhao Wenzhong of the New Rural Development Institute to form a team of science and technology service experts，In order to improve the planting technology of villagers and make reasonable use of the space under the forest，Expand marketing channels for agricultural products，Consolidate the achievements in poverty alleviation，Boost rural revitalization，Science and technology special correspondent of Northeast Agricultural University carried out science and technology to prepare for spring ploughing service in 4 townships of Zhaodong City。

Technical exchanges were carried out around the utilization of orchard space in Julin village, Sizhan Town，On the basis of fully understanding the characteristics of orchard growth，Targeted for the villagers to explain fruit bacteria interplanting, fruit and vegetable interplanting model，This technology can make rational use of orchard space，It does not affect the normal growth and development of fruit trees，After the fruit trees were picked, edible mushroom cultivation was carried out in the shade under the forest，Increase farmers' income。In view of the short picking period after fruit fruit, not easy to store, the sales price is not high, it is recommended to rough processing fruit into dried fruit, canned fruit, etc., to increase income。This scientific and technological service helps villagers develop ideas, increase professional skills, and provide ideas and solutions for rural development of characteristic planting。

Under the leadership of Pan Junlin, deputy secretary of Jiangjia Town, Zhaodong City, the group came to the vegetable planting base of Shuangan Village, Zhaodong City, conducted field research and guided the comprehensive utilization of corn stalks and did technical training for the villagers。It is expected to use corn straw as seedling substrate and mushroom as starting point to extend agricultural industry chain, promote agricultural efficiency and increase farmers' income。A team of experts in Shuangan village vegetable planting base to guide farmers to use corn stalks to prepare vegetable seedling substrate，The seedling is raised according to 30% straw matrix，Turf soil 30%，蛭石20%，Perlite is added in 20% proportion，The seedling substrate prepared，It can reduce the consumption of grass charcoal，And the straw is converted into a substrate，Rich in nutrients，The seedling rearing effect is excellent。Zhang Di introduced in detail to Wang Xiaoru and others the precautions for the use of corn straw to prepare vegetable seedling substrate, and Liu Huajing introduced in detail the technology of using straw to grow edible fungi。

Then the participants carried out technical exchanges on comprehensive utilization of crop straw in the conference room of the village Committee，Wang Zhnian, Secretary of Jiangjia Town, introduced the implementation of straw green (yellow) storage, wrapped microstorage, compaction (particles), biomass power generation, straw molding fuel and other technologies in Jiangjia Town in detail，And highly praised the expert team to open up the comprehensive utilization of straw in Jiangjia town，Helped the local vegetable planting industry cluster to solve the key production problems。

In the afternoon, a group of experts came to the Zhaodong Song Station town where the teacher Wenzhong Zhao served, and deputy Mayor Zhang Xinmin, a temporary cadre, contacted several local farmers to come and talk。Song Station village Wu Zhendong growers, in recent years, the circulation of 3000 acres of land, this year plans to plant 500 acres of soybeans, soybean production in the past only maintained about 200 jin/mu, even with the planting of soybeans subsidies, income compared to planting corn is still very different。Experts carefully help from the soybean seed, soil physical and chemical properties determination, application of soil amendments, field management and marketing, so that the planting of soybeans and corn as much as possible income, so that farmers eat peace of mind, while responding to the provincial planting structure adjustment policy。

In order to improve the single planting mode of field corn, Dongnong experts brought fresh corn seeds with sweet and glutinous taste for many years to be tested by large corn growers, and detailed guidance was given to planting links such as fertilization and picking of cash crops。

This year, Dongnong Bean 252 was planted in Songzhan Town and used as raw material to process soybean milk, ice cream and other products，Sheds grow high-sugar 100 fresh tomatoes，Take these two agricultural products as the mainstay，Experts at the meeting gave advice on how to carry out Internet marketing and local anchor training，Set up tourist signboards by combining the name of the railway station with "the only word in China"，Promote the local Middle Eastern railway culture and excellent ecological environment。

Anmin Township of Zhaodong City mainly grows corn, with a planting area of 16.5万亩。Guo Shudong, chairman of the National People's Congress of Anmin Township, received the experts and their delegation。Mr. Li Wei discussed with large growers and the president of the Chamber of Commerce in Anmin Township how to increase production in local corn planting, mainly focusing on corn cultivation, straw returning to the field, corn fertilization ratio and organic alternative fertilization and other issues。Teacher Li Wei also went into the homes of farmers and answered the questions raised by the villagers in detail, guiding farmers how to carry out rapid aerobic composting of cow manure, which not only protects the environment but also increases the income of farmers, and helps villagers solve the problem of environmental pollution caused by cow manure accumulation for a long time。

At the matchmaking meeting, the expert group brought 500 popular science books and CDS, covering fruit tree cultivation, edible fungi cultivation, fresh corn planting, black land protection and agricultural products e-commerce, and established a wechat group with local growers to provide agricultural technology guidance and services at any time。
