Watch spring plowing with good scenery all year round。Before Qingming Festival，Professor Zhao Wenchao from the “National College Huang Danian Teacher Team” of modern horticulture in our school、Professor Zhang Guoqing、Associate Professor Zhang Qing、Associate Professor Zhao Bo、Associate Professor Sun Lulu、Associate Professor Huang Huang led graduate party members to several “doctoral farms” in Pinggu to guide spring plowing and management。
“A large area of new leaves has wilted on fruit tomatoes grown in solar greenhouses，Teachers please give me some advice。”At Dr. Tomato and Cucumber Farm in Ji Taiwu Village, Xiagezhuang Town，The person in charge of the base asked anxiously，The teachers actively helped analyze the causes of the disease and explained in detail the precautions for spring tomato management。The person in charge of the base recorded it carefully，Brows gradually relax。
At Dr. Green Onion Farm in Donggaocun Town，We conducted an on-site investigation on the cultivation of green onions and the production of early spring vegetables at the base。Teachers’ comments on early spring green onion seedlings and cauliflower currently grown at the base、Cale、Proposed management measures for the management of fruits, onions and other previous crops。We also had an in-depth discussion on the four-season supply strategy for green onions。bet365 online sports betting liveZhang Guowei, president of the Beijing Weijie Yuhan Vegetable Professional Planting Cooperative in the village, also presented a banner to Sun Lulu，“Thank you, Mr. Sun, for your help and support in all aspects of the cooperative in the past two years，Let us taste the sweetness of promoting agriculture through science and technology。”
Teachers from the modern horticulture teacher team expressed their opinions，Will continue to vigorously promote Professor Huang Danian's "Heart has a big self"、The spirit of serving the country with sincerity，Closely combine teaching and educating people with serving rural revitalization，Continuously raising sweet potato seedlings、Tomato planting、Jujube tree pruning、Orchard Planning、Carry out social service work in the fields of edible fungi cultivation，Making positive contributions to the construction of Zhongguancun in agriculture and the capital of seed industry。
"The sweetness of Buddha's delight in pears is due to the contributions of Beinong teachers and students"
“Now the population density of pear psylla is larger in middle orchards，Need to be dealt with quickly，To prevent greater impact on the growth of pear trees。”April 7，The person in charge of Fojian Xili Science and Technology Courtyard in Houcun, Maoshan、Associate Professor Ren Zhengguang of the School of Biology and Resources and Environment of our school led graduate students to Maoshanhou Village, Jinhaihu Town, Pinggu District to conduct research on the growth of Fojianxi pear，And guide fruit farmers in the prevention and control of pear tree diseases and insect pests in spring。
Before and after Qingming，Sudden rise in temperature，It is the time when the overwintering adults of pear psylla emerge from hibernation，The Science and Technology Courtyard team separately visited the old orchard in Houcun, Maoshan、The occurrence of pear psyllid in middle orchards and young orchards was investigated，It was found that the population density of pear psyllids increased rapidly in Zhonglao orchards，It is recommended that fruit farmers spray lime sulfur mixture before germination to prevent and control overwintering pests and pathogens，Then control pear psylla by hanging yellow armyworm boards。
Pear trees cannot thrive without fertilization，Local soil and correct fertilization methods can give the Fojianxi pear in Maoshan Hou Village a unique flavor。Ren Zhengguang guides fruit farmers to apply microbial fertilizer in spring，Not only improves soil fertility，Increased the number and activity of beneficial microorganisms bet365 online sports betting mobilein the soil，Improved plant disease resistance，Reduced use of chemical fertilizers，Reduced the occurrence of pests and diseases in pear orchards，Thus improving the yield and quality of pear fruits。The fruit farmers said happily: "I look forward to another bumper harvest this year，Buddha sees the sweetness of pear，Thanks to the contributions of Beinong teachers and students。”
“An expert ‘takes the pulse and prescribes’ for the orchard，We feel much more at ease”
Recently，Professor Cao Qingqin of the School of Plant Science and Technology led a team to guide local fruit farmers in the Guajiayu Science and Technology Yard and Doctoral Farm in Dahuashan Town, Pinggu District to carry out orchard spring management and pruning，Hingyu Pinggu District Fruit Industry Service Center、Village and town leaders and technical backbones discuss and exchange。
Cao Qingqin came to the orchard，View the growth of fruit trees in detail，“We must promptly remove diseased and insect-infested branches in the peach orchard，Don’t let them affect the growth of fruit trees。”In view of the serious bacterial black spot disease of large peaches and uneven fruit coloring during the production process，She suggested that the color of the fruit could be improved by laying reflective mulch。“Now is a critical period for orchard management，An expert ‘checks the pulse and prescribes’ for the orchard，We feel more at ease。"The technical backbones expressed their opinions one after another。
“I feel extremely proud to use technology to help morels produce more”
Recently，Professor Chen Qingjun, School of Plant Science and Technology, Beijing Edible Fungi Industry System Expert、Professor Zhang Guoqing，Leading the graduate student team into Lianjiaying Village, Shenjiaying Town, Yanqing District，Sending high-quality morel strains to the village collective and demonstrating and promoting soil treatment、Environment Control、Full set of cultivation techniques including mushroom management，Promoting the development of morel industry、Promote farmers to increase production and income。
Morchella as a precious edible fungus，Always favored by the market。However，Suffering from lack of good strains、Restricted by many factors such as backward planting technology，The villagers of Lianjiaying Village have long faced many difficulties in growing morels。Since Chen Qingjun、Zhang Guoqing went to the village to provide technical guidance，The villagers gradually mastered the planting skills。
“The temperature has changed a lot recently，The ground temperature is relatively low at night，May affect the growth of small mushrooms。”Grower Master Zheng is worried about the impact of low bet365 online sports betting apptemperature on morels，Please ask Zhang Guoqing for guidance。“Morels are more delicate，Requires a relatively stable growth environment。Use plastic film to support the buffer zone at the shed entrance，Avoid cold wind blowing in and out of the greenhouse、Causing dead mushrooms。”Zhang Guoqing provided detailed technical guidance。“The top priority now is to increase the temperature in the shed，You can build a small arch in the shed to increase the soil temperature，Ensure the stability of mycelial growth environment，Soil temperature 8-15℃、The temperature of 18-20℃ promotes the differentiation of morels”。
Our school’s edible fungi team united with the village collective cooperative to sow a total of 58 sheds of morels in 2023 (28.5 acres)，Currently mushrooms are starting to appear，The expected yield per mu is 500 kilograms，Output value exceeds 1.5 million yuan。Chen Qingjun provides on-site guidance on planting and management during the fruiting period，"Management after pouring mushroom-stimulating water，Is the key to high yield of morels，Need to adjust the greenhouse insulation quilt，Fill light to increase mushroom temperature，We must insist on "two ups and two downs" every day。" Chen Qingjun introduced in detail，"The sun is weak in the morning，The temperature inside the shed is low，The insulation is all rolled up，The temperature rises around 10 a.m.，Just put down the thermal quilt；2pm，Diminished light，Roll up the insulation quilt again to add light，Put it down at 4 o'clock...suitable temperature and uniform light，Promote morel primordium differentiation。”
Since October last year，Qiao Ying, a graduate student at the School of Plant Science and Technology of our school、Jia Kai、Wei Zihan、Cao Boshuo and others live and eat together with the base growers，Participate in the whole process of morel cultivation in Lianjiaying。It’s great to see the morels growing，Qiao Ying was very excited: “The morels in shed 143 are 6 strains that I screened using cross-breeding methods，Currently, they have entered the mushrooming stage，A large number of small mushrooms have formed，I have already felt the joy of harvest in advance。" Wei Zihan said，As a graduate student in a special class in a small college of science and technology，Through more than half a year of field practice，Solved the local technical problem of morel cultivation，Help villagers increase their yields and increase their income，Feeling extremely proud and proud。“I will closely integrate classroom learning bet365 online sports betting appand rural practice，Contribute youth to the capital’s comprehensive promotion of rural revitalization。”
