He realized his dream of becoming rich in the mountain village with walnuts.

It is not easy for such a small mountain village to develop.

Gaojiazhuang, Puji Town, Jiaozhou City, Qingdao City, Shandong Province is a migrant village in the reservoir area. Most of the land in the village is mountainous and hilly, with thin soil layer and sand and gravel soil. In order to change the poverty and backwardness of the village, Song Jianchun has worked hard to find a way to develop the economy since he became secretary of the party branch of Gaojiazhuang village in 2008. To this end, he visited and studied many times, hired relevant experts to demonstrate, and finally chose to plant thin-skinned walnuts in Gaojiazhuang and set up a walnut professional cooperative in Gaojiazhuang.

Under his leadership, the members of the cooperative built roads and bridges, prepared the land and improved the soil, and with a great effort, they planted 1200 mu of walnut ecological forest on layer by layer of terraces. In order to better grasp the growth habits of walnut, Song Jianchun organized members to visit and study in Jinan, Linyi and other places to participate in all kinds of forestry technical training, and invited experts from Qingdao Agricultural University and Hebei Green Ridge Company to provide on-site technical guidance for members. In order to broaden the channels to increase income, Song Jianchun combined with the actual situation of the cooperative and developed the breeding industry in the forest according to local conditions, raising 1000 chickens and ducks per mu of walnut forest.

Walnut planting is inseparable from scientific management.

To this end, Gaojiazhuang Walnut Orchard has built a water storage flat pond with a storage capacity of 32000 cubic meters, and all adopted water-saving irrigation technology, with a water-saving irrigation network reaching 1600 meters; a walnut storage and processing comprehensive building of 1200 square meters has been built; and all walnut orchards have hardened roads, with a hardened area of 13000 square meters.

In 2013, the "Gaojiazhuang brand" thin-skinned walnut trademark approved and registered by the State Administration for Industry and Commerce became a well-known characteristic brand. The cooperative also docked with several supermarkets and wholesale markets in Qingdao, and Gaojiazhuang walnut became a hot product.

After nearly six years of continuous efforts, Gaojiazhuang walnut professional cooperative has 154 members, walnut planting base has an annual output of 90,000 kg, annual sales of more than 3 million yuan. Every year, in addition to 20, 000 to 30, 000 yuan of income from walnut production, farmers can also receive dividends from the cooperative's land shares, with an annual income of 1600 yuan per share. In 2015, the villagers in the village planted walnuts alone, and the per capita annual income reached 4100 yuan, and the per capita economic income under the forest reached 1100 yuan.

At present, Gaojiazhuang Walnut Orchard has become "Qingdao training Base for Modern Agricultural Science and Technology talents in Western Development" and "off-campus Scientific Research Base of Qingdao Agricultural University". It is also the only high-quality thin-shell walnut planting demonstration base in Shandong Province. Gaojiazhuang Walnut Professional Cooperative has successively won the titles of "leading Forestry Cooperative of Shandong Province", "one Village and one Product demonstration Village in Qingdao", "Ten leading Forestry Enterprises in Qingdao" and "safe Agricultural products production Base in Jiaozhou City". In 2015, Qingdao Gaojiazhuang walnut professional cooperative was named as the national forestry professional cooperative demonstration society.
