More than ten years as a day，He went deep into the fields of Beijing to promote agricultural technology，Footprints can be found in various towns and villages in the suburbs of Beijing，Write scientific papers on the land of the motherland，Realized Beijing sweet potato varieties，For rural revitalization、Contribution to increasing farmers’ income and developing sweet potato industry。He is Zhao Bo, associate professor at the School of Plant Science and Technology, Beijing Agricultural College, who was named "Advanced Individual in Rural Work in Beijing (2017-2021)"。
Promote new varieties and increase sweet potato yield to more than 3,000 kilograms per mu
More than ten years ago，Zhao Bo has done a survey on grower behavior analysis，It was found that more than 70% of farmers most want support from new varieties，The second is support for mechanized planting technology。Think what farmers think，The anxious farmers are anxious，Zhao Bo started to set his ambition from then on，Dedicated to promoting new varieties for many years、Simplifying cultivation technology work，Do everything possible to increase farmers’ income。"What do farmers need most，Let’s start from where to help them。”he said。
Since 2016，Zhao Bo set up a new variety test demonstration field in the sweet potato production field in the suburbs of Beijing，Introduced Tobacco Potato 25、New sweet potato varieties such as Pushu 32，Move the laboratory to the fields，Accelerate the promotion and application of new varieties。
After local production evaluation and market feedback，Shixia Sweet Potato Planting Cooperative, Gaoling Town, Miyun District, determines Pushu 32 as the main planting variety，Promote the update of sweet potato varieties in Miyun District。The yield of new sweet potato varieties in Fangshan District reaches more than 3,000 kilograms per mu，The formation is mainly new varieties、Sweet potato variety matching model featuring old varieties。bet365 online sports betting mobileIn Xiagezhuang Town, Pinggu District，The introduction of new varieties has increased the yield of sweet potato per mu from 700 kilograms to more than 3,000 kilograms，The average output value per mu reaches 9,000 yuan。
“Transformation of Agricultural Science and Technology Innovation Achievements，It must be reflected in the farmers’ bulging ‘money bags’。" Zhao Bo said，"Only this way，Farmers will be more motivated to produce，Only can we achieve the goal of promoting agriculture through science and technology。”
After 5 years of hard work from 2016 to 2020，The fifth generation of new sweet potato varieties in Beijing from point to surface、From village to town、Comprehensive update from the district to the city，The application area has grown from less than 5% in 2016 to more than 95% in 2020，Realized the replacement of new sweet potato varieties in Beijing，The output increased from 1500 kg/mu to more than 3000 kg/mu。
“New sweet potato varieties meet the market’s requirements for fresh food varieties in terms of taste and appearance quality，Sales price increased，Sweet potato farmers’ economic benefits have increased significantly。”Zhao Bo is very pleased with this result。
Promote planting technology and increase sweet potato yield per mu by more than 20%
Promotion and upgrading of new sweet potato varieties，It must be closely integrated with the promotion of planting technology to achieve higher efficiency。“There is currently a small number of young and middle-aged labor force in rural areas，Most of the people in the village are women and the elderly，This requires improving mechanization to liberate the labor force。”For this，Zhao Bo explored the technology of dense planting and shallow planting of sweet potatoes，Control the shape of sweet potatoes by adjusting planting density，Plant the potato seedlings shallowly into the soil to increase the potato setting points and thereby increase the yield。
But the promotion of new technologies is a slow process。At first he went to rural areas to give lectures and training，Older growers do not recognize this technology，It is often the expert who has just finished giving the lecture and left，They still grow sweet potatoes in their own way。
As time goes by，Zhao Bo realizes，The promotion of planting technology cannot only be through lectures，Still needs to pass test demonstration、On-site visit、On-site bet365 online sports betting appguidance and other means，In order to be more intuitive、More convincing，Farmers can better understand it if they understand it。So，He simply went to the fields to demonstrate new planting techniques，Wait until the sweet potatoes mature in autumn，Let me show you the results。Growers found that using the planting methods he taught can really produce more fruits，So I gradually changed my mind，Starting to accept new technologies。
In order to improve the commodity rate and yield efficiency of sweet potatoes，The sweet potato planting season comes every year，Zhao Bo went deep into the fields，Explain and demonstrate to farmers the technology of dense planting and shallow planting of sweet potatoes。After years of hard work，The planting density of sweet potato production fields in Beijing has increased from 3,000 plants/mu 10 years ago to more than 4,000 plants/mu now，The application rate of dense planting and shallow flat planting technology has increased from 30% to the current 80%。Densely planted and shallowly planted technology significantly reduces the proportion of defective tubers，Sweet potato commodity rate increased from 70% to 85%，Profit per mu increased by more than 20%。
In addition to promoting sweet potato planting technology，Zhao Bo is also committed to promoting advanced cold bed seedling breeding technology，Improving the level of sweet potato seedling cultivation in Beijing。After efforts in recent years，Beijing successfully promoted new sweet potato cold bed seedling technology，Select by facility、Seedbed construction、Stacking seed potatoes、Covering soil thickness、Temperature control、Improvements in disease prevention and control，Increases the weight of 100 potato seedlings from 250 grams to more than 500 grams，The quality of seedlings is significantly improved，Energy consumption and pollution are significantly reduced。
Befriend farmers and spend more than 100 days on the front line every year
Since participating in the sweet potato technology promotion work in Beijing，Zhao Bo’s footprints can be found in various towns and villages in the suburbs of Beijing。In the past 10 years，He has been in the countryside for more than 1,500 days in total，Carry out 79 sweet potato production technology trainings，Trained 2,800 farmers，Surveyed 24 sweet potato production units，bet365 games best slotsVisited farmers more than 230 times；A total of 27,000 acres of sweet potato demonstration fields have been helped by production units and individuals，Guide the construction of cold bed sweet potato nursery 4.50,000 square meters，Guide the construction of 3 sweet potato storage warehouses，Promote 11 new varieties，Promote 3 new cultivation techniques。
Zhao Bo’s agricultural practice and scientific research complement each other，Over the years, he has hosted and participated in 12 scientific research projects on the genetics and breeding of edible beans，Won 1 Beijing Science and Technology Award；Presided over 1 scientific research project on sweet potato variety selection and promotion。Teaching courses such as "Agriculture", "Agricultural Extension", "Crop Cultivation"，Won 1 Beijing Education and Teaching Achievement Award。
What makes Zhao Bo insist on going deep into the front line of "agriculture, rural areas and farmers" to promote technology，In addition to his love for this cause，There is also farmers’ desire for new technologies and their high recognition of them，They recognize him from the bottom of their hearts、Respect him。
Once，Zhao Bo conducts training in a rural cooperative in Miyun。Talking and talking，He found that every time he said a word，The villagers next to you just make gestures，My hands are probably sore after one class。After class，He was curious and found out after asking，The person is interpreting in sign language to "listen" to the hearing-impaired companion。“The village party secretary told me，This hearing-impaired villager learned this technique，Earn eighty yuan a day，My life will be settled。”Hear this，His eyes suddenly became moist，A sense of accomplishment arises，I feel extremely satisfied inside。
Now，Zhao Bo goes to farmers’ fields every month、Take a look，Understand the current planting situation and needs of villagers。By promoting new varieties and new technologies，He helped many incompetent people、Villagers who have no conditions to go out for employment can create income at home。What makes him proud，Every time I come to the village，The villagers will talk to him about the planting situation，Sometimes they even have sex with each other，Even warmly invited him to have dinner at home。He knows that the villagers no longer regard bet365 online sports betting apphim as a great expert from the city，More like treating friends around you，This makes him feel very proud ，It also made him more determined to serve the "three rural issues"。
