Professor Gao Chengda from the School of Grammar and Urban-Rural Development led students to the Guotao Base in Liujiadian Town, Pinggu District，Measurement of negative oxygen ions and soil moisture content in Taoyuan，Understand the ecological environment factors of Taoyuan。"Negative oxygen ions，Also known as ‘air vitamin’，" Gao Chengda explained to the students，“The World Health Organization defines clean air as a concentration of negative oxygen ions reaching 1000-1500/cm³，Now the concentration of negative oxygen ions in Taoyuan has reached 6000/cm3，Indicates that Taoyuan’s ecological environment is very good。”Gao Chengda also led the students to Liu Wange, a farmer in Yindong Village, Liujiadian Town, Pinggu District、Hu Dianwen’s Peach Land，Conducting Taoyuan soil-atmospheric carbon dioxide flux observation。Students who participated in the practice said: "Follow the teacher and go deep into the fields，Passed Taoyuan on-site ecological environment index testing and measurement work，Learn the skills to use instruments and bet365 online sports bettingequipment，Improved hands-on practical ability，Feeling full of gains。”
The special soybean research team of the Northern Crop Science Discipline went to the National Modern Agriculture Industrial Park in Xuanhua District, Zhangjiakou City for spring plowing guidance，And promote Beijing Agricultural College soybean varieties and methods。Since spring plowing，Teams come to Changping one after another、Soybean farmers in Zhangjiakou and other places、Soybean production enterprise、Changping District Agricultural Service Center conducts spring plowing production technology training and guidance，Promote soybean varieties with specific uses。Introduction to Li Weiyu，The special soybean team is committed to cultivating new high-yield and high-quality special soybean varieties，4 new soybean varieties，2 new variety rights from the Ministry of Agriculture。The team invented the soybean seed germination nutrient solution、Field Seeder、Plant spacer、Pre-sowing germination rate detection device and other equipment，Promote the establishment of an efficient soybean breeding platform，further promotes the promotion of smart agricultural planting models with improved seeds and methods。
Associate Professor Zhang Qing from the School of Plant Science and Technology went to Taoyuan, Suziyu Village, Dahuashan Town, Pinggu District to conduct flower and fruit management technology training。Aiming at the problems of poor development of peach blossoms and low pollen quantity caused by the advance of the growth phenological period of large peach and the change of temperature，Zhang Qing guides Suziyu peach growers to carry out flower thinning and pollination work。Working through flower thinning and pollination，Will save the tree’s stored nutrients、Reduce deformed fruits、Improve fruit setting rate、Increase fruit weight。“Teacher Zhang Qing’s technical guidance is so timely！”Peach growers bet365 games best slotssaid，“Teacher Zhang’s guidance is practical and easy to learn，It allows us to save labor and effort，It can also increase the yield of large peaches，We are more confident about this year’s harvest。”
Professor Cao Qingqin from the College of Plant Science and Technology came to Guajiayu Village, Dahuashan Town, Pinggu，Guide peach farmers to configure pesticides to manage peach tree diseases and pests。“Peach trees need to be treated for aphids during the flowering period、Pear heartworm、Prevent thrips and other pests in advance，By spraying pesticides、Hanging directional silk and other wires to reduce the damage of pests to peach trees。"Cao Qingqin guided the fruit growers，While teaching students the meaning and method of thinning flowers。“Reasonable flower thinning can avoid ineffective consumption of nutrients，Reduce the proportion of self-thinning young fruits and ineffective flowers，Thus increasing the fruit setting rate，It has achieved stable production for consecutive years、Necessary measures to increase production。”
Associate Professor Wang Shunli of the School of Biology and Resources and Environment led students to Beijing Lupu Fangyuan Flower Technology Co., Ltd. to collect samples of flower waste straw compost。The team started composting experiments in March this year，Set different material ratios and inoculate lignocellulose-degrading microbial agents screened in the laboratory，Provide technical guidance for the resource utilization of large amounts of flower straw and surrounding woodland fallen leaves produced by agricultural-related enterprises every year。Sophomore Yang Zhenkun said: “What you see on paper will eventually make you feel shallow.”，Knowing that you must do this。Through on-site learning and operation，I understand the key points of composting technology、Microbial agent screening methods and application bet365 online sports betting appin compost, etc.，Learning while practicing on the front line，More impressive，More proficient in mastering knowledge and skills。”
Spring is the time for sowing green onions、Nurture、Critical period for breeding，The spring plowing work at Dr. Zhaojiajia Village, Donggaocun Town, Pinggu District, “Jingdong’s No. 1 Green Onion”, is proceeding in a busy and orderly manner。The person in charge of the doctor’s farm is Dr. Sun Lulu, a teacher at the School of Plant Science and Technology, Beijing Agricultural University，She and her colleagues completed the soil test on Zhao Jiajia’s green onions，Find the reason for continuous cropping problems in green onion soil，And put forward corresponding countermeasures，Established a green prevention and control technology system for Zhaojiajia green onion production，Guide and train cooperative villagers on organic cultivation techniques of green onions。The focus of this year’s work is the construction of a green onion standardization base。Since the beginning of spring，The expert team of Doctor Farm has started a new round of work，Combining national and local standards for green onion production，Guidance on spring sowing of green onions、Nurture、Multiple species，Laid a solid foundation for the high-quality and high-yield and high-standard base construction of Zhaojujia green onions in autumn。The eve of May Day，Zhao Jiajia’s green onion planting technology was selected into the “Sixth Batch of District-Level Intangible Cultural Heritage Representative Directory of Pinggu District”。
