During the epidemic in early 2020，Graduate students from the Edible and Medicinal Fungi Research Group of Beijing Agricultural College came to the "Beijing Science and Technology Yard No. 038, Tongnong No. 038" located in the Qianbaijia Edible Fungus Cultivation Cooperative in Dahuashan Village, Dahuashan Town, Pinggu District, Beijing.。In response to the party’s opinions on comprehensively promoting rural revitalization and accelerating the modernization of agriculture, science and rural areas，Let technology enter the fields，In the United Front Work Department of the Municipal Party Committee、With the cooperation of the district government, Beijing Agricultural College and other parties，Based on the local edible fungi cooperative’s own situation，Established "Tongnong No. 038 Beijing Science and Technology Institute"。The Science and Technology Institute guides and supports the majority of scientific and technological personnel to carry out resident research、Working Demonstration，Insist on "zero distance、Zero threshold、Zero time difference and zero fee” principle of serving farmers，Eat together with local farmers through scientific researchers、Living together、Form of "same labor"，Exhibiting "technological innovation and achievement promotion、Technical support and technology services、Talent training、Enrich rural life、Precision technology assistance” and other functions。The main job of "Tongnong No. 038" is to cooperate with Beijing's "Ecological Bridge" project，Help dispose of local waste、Recycle discarded peach branches from local farmers，via Crush、A series of operations such as composting，Make various mushroom sticks，Finally bring the produced mushrooms to the market，Realizing bet365 online sports betting mobilewaste matrix utilization。
“The three-month internship time that took root in the courtyard flew by in vain，Looking back now, I can still think of the scene of mixing things with the members at work，Aunt Liu prepares big peaches for us after work，How I make dumplings with my juniors and sisters during dinner。Three months not only taught us how to use peach branches to grow edible fungi at the base，It also teaches us how to get along with others in life。”September 2020，Guo Yuxin, a graduate student majoring in horticulture at Beijing Agricultural College、After Yang Qizhi and other students stayed in Beinong Xiaoyuan for 90 days，Departure back to school。
It is common to grow mushrooms with sawdust，But specific analysis of specific issues，When the students calculate the recipe and finish the ingredients，When I was preparing to pack the bags the next day, I discovered a serious problem。Because the crushed peach wood chips become vertical needles，It is easy to puncture the bag when filling it，How to solve it？Instructor Chen Qingjun、Zhang Guoqing collaborated with the president of the cooperative to discuss the plan with the graduate students，Reduce the proportion of peach wood chips in the formula，Increase composting time at the same time，The bagging phenomenon is much better，Solved practical problems in production。
"The main work tasks in the Science and Technology Courtyard are divided into three categories。The first task is to help the cooperative solve the problem of culture material supply in different villages。We need to collect agricultural waste from farmers、Smashed、Pre-moistened and composted to make culture material for edible fungi cultivation。The second task is the spring oyster mushroom production of the cooperative。During this period，I learned the entire production process of oyster mushrooms。This includes ingredients、Compost、Bagging、vaccination、Bacteria Checker Stick、Daily management and harvesting work。" Yang Qizhi, a second-year graduate student, introduced: "We collected samples during the planting process and took them to the Edible Fungi Laboratory of Beijing bet365 online sports betting liveAgricultural College for testing，Compare different production formulas，Screening the optimal formula and optimal process。From the initial composting to the subsequent land preparation and ridge making in the greenhouse、Paving materials、Sowing、Cover with soil, grass, etc.。Many tasks make everyone feel that the burden on them is getting heavier，But it did teach us a lot。”
6:00 every morning，The students have already gone downstairs to start their daily work，Work will continue until 6pm。At noon and evening，Guo Yuxin and Yang Qizhi will take turns cooking some homely meals，There are also some fresh mushrooms just picked in the greenhouse on the table。Everyone lives together like a family，It’s fun。“What impressed me most was making dumplings with my classmates。Let’s make noodles together、The scene of making dumplings is still vivid in my mind，This really makes me feel warm and happy，It feels like home。" said doctoral student Guo Yuxin。
In these more than 100 days，Guo Yuxin、Yang Qizhi also gained his own academic achievements。Master student Yang Qizhi and doctoral student Guo Yuxin respectively determined their own topics，That is, "Research on the high-yielding formula and technology of Sphaeroides macrocepha based on peach sawdust" and "Research on microbial dynamics and lignocellulose degradation rules during the fermentation of peach sawdust and cultivation of Oyster Mushrooms"。Yang Qizhi published an article in the Chinese Agricultural Science Bulletin titled "Analysis of Agronomic Characteristics of Spheropsis Cultivation with Different Formulas and Techniques in Solar Greenhouses"，Guo Yuxin’s first English article "Succession of the microbial communities and function prediction during short-term peach sawdust-based composting" published in the journal Bioresource Technology，The impact factor is as high as 7.539。
In these short few months，Everyone learned、I learned a lot。Yang Qizhi after returning to school，I often say this to my friends around me: "This trip to the courtyard has benefited me a lot。In scientific research，I learned about oyster mushrooms、The overall production process of bet365 online sports betting liveSphaeroides globus and other edible fungi；Understand how to control the moisture content of planting materials、pH value；How to control the weight of culture material in the bacteria rod；Learned many experimental skills such as open vaccination，This also made me understand that what you see on paper is ultimately shallow.，Knowing that you must do this。At the same time, I have screened out the best cultivar formulas and the best culture material formulas for growing Sphaerophora macrocephaly。At work，I also realized the importance of details，Any detail may lead to serious consequences。Life in a small courtyard makes me realize that we need to make reasonable use of our daily time，Whenever I see that my workload in one hour is not as good as half an hour of work by the members，I understand that you have to use your brain to do things，Time must also be allocated reasonably。In life，I understand the gap between school and society，Here，My daily interactions with farmers and cooperative members have trained my ability to communicate harmoniously with others，Daily cooking、Doing laundry and picking vegetables have exercised my most basic life skills。”The graduate students who have taken root in the small college finally understand that the ancients once said that every particle is hard work，I also understand what it means to suffer hardships，Fang Weiren, Master。Hardship，Yu Ru Yu Cheng。Life in the small college brings different experiences and learning to graduate students、Harvest in life，This kind of experience will always inspire everyone to move forward in the future。
