A few days ago, the national labor union won the “national labor pioneer” medal and the “national labor pioneer” medal in 2022. Li Baoguo, a researcher of the College of forestry of Hebei Agricultural University and the innovation team of mountain development and forest and fruit industry (hereinafter referred to as the innovation team), was awarded the “National worker pioneer”.

“This is both an honor and a responsibility. We will continue to do a good job in Li Baoguo’s unfinished business and let farmers take on the ‘golden shoulder’ of science and technology.” Guo Suping, head of the innovation team, said.

“Mr. Guo Suping is a practitioner of inheriting and carrying forward the ‘Li Baoguo spirit’. For six years, our team has been committed to the comprehensive development and management of mountainous areas and the development of characteristic economic forest industry.” Zhang Xuemei, associate professor of Forestry College of Hebei Agricultural University, said that the team has undertaken 34 projects above the provincial level, promoted 36 practical technologies, selected and approved 9 varieties… These achievements have enabled people in Taihang mountain area to do ecological work and eat ecological food.

Breaking the bottleneck of rural industrial development with scientific and technological innovation

After Li Baoguo’s death, Guo Suping took over her husband’s lifelong career and continued to run in the front line of agricultural technology promotion. On April 29, Guo Suping came to Lvling walnut Town, Lincheng county. “At present, walnuts are in the period of fruit expansion. I can’t rest assured. I have to come and have a look.” Guo Suping walked to a walnut tree bearing fruit and said that the soil during the expansion period should not be short of water. It has to rain these two days. After a sunny day, it should be sprayed with polyantimycin or chunleimycin to prevent bacterial black spot… Under the guidance of Guo Suping, the walnut garden has become a science and technology classroom. The farmers who got the technical guidance burst into a smile. They knew that these walnut trees could be fruitful again this year.

In the vast Taihang Mountains, there is a village surrounded by fruit trees, which is Qiannanyu village, Xindu District, Xingtai City, where Professor Li Baoguo has fought for more than 30 years. Li Baoguo and his innovative team have created an ecological economy with the characteristics of Taihang Mountain here, and created a three-dimensional new model of wearing hats in the birth forest, wrapping the waist in the dry fruit forest and high-efficiency fruit living in the field.

Barren hills become rich hills, and barren mountains become green mountains. “In the past, the mountain was full of bare gneiss, and nothing was long. Professor Li Baoguo tried to plant fruit trees here and solved many mountain governance problems by using scientific and technological means, so that we can have today’s economic forest industry development.” Guo Tianlin, former party secretary of Nanyu village, said with emotion that through the adoption of modern agricultural planting technology, our pulp apples bid farewell to the confusion of bad growth and unsalable.

In view of the “drought, thin, erosion, poverty and low” situation in Taihang mountain area, Li Baoguo led the team to creatively develop key technologies such as blasting and land preparation, construction of slope separated and gully terraces, water storage and water conservation, flood control and disaster reduction, and soil fertility. He integrated and assembled the standardized technology of basic engineering for the comprehensive development and treatment of gneiss mountains in Taihang mountain area, and built high-standard slope separated and gully terraces.

Today, “Li Baoguo spirit” continues to be inherited in Taihang mountain area. Guo Suping introduced and developed more than 100 mu of soft jujube kiwi fruit for Qiannanyu village, with an average annual income of more than 70000 yuan per mu.

Guo Tianlin said that at present, more than 27000 mu of apples and nearly 60000 mu of chestnuts are planted in Jiangshui Town, and the annual output value of forest and fruit alone reaches more than 200 million yuan. Driven by the Qiannanyu economic forest model, the mountains in Taihang mountain area are green, the village is beautiful and the people are rich.

Building the development model of rural characteristic industries according to local conditions

In order to revitalize the countryside, industry must go first. How to make scientific and technological innovation support the development of rural industries? Li Baoguo and his innovation team have made various scientific and technological innovations to support the development of industries with local characteristics according to local conditions.

The technology of continuous planting of large apple seedlings has “flew” from Taihang mountain area to Yanshan mountain area. Luanzhou Jiguanshan ecological agricultural industrial park is the last base for Li Baoguo’s assistance. Through assistance, the barren mountains and bald mountains with vertical and horizontal gullies and overgrown weeds have now become a comprehensive development zone for industrial integration and development integrating organic planting, characteristic breeding, sightseeing tourism and agricultural product processing.

“Guo Suping always has fruit farmers in her heart. She often brings agricultural experts to spread new ideas and technologies.” Wu tieyou, chairman of Jiguanshan ecological agriculture industrial park, said that the intelligent management of light, temperature and water in the solar greenhouse in the park has been realized, and scientific and technological elements have been injected into all links of planting management.

According to the unique collective economic model, Qiannanyu village has developed tourism picking and fruit processing industries of characteristic economic forests such as cherry, soft jujube and kiwi fruit. Relying on the unique resources such as Li Baoguo cadre college to develop red tourism and ecotourism, a three industry integrated development model of “collective + farmers” is formed.

Lincheng Lvling walnut town integrates the research and development, breeding and planting of high-quality thin skinned walnut varieties, the development and sales of deep-processing products, and eco-tourism. It has innovated the three industry integrated development model of “large park + small owner” with walnut as the main line.
