Professor Cao Qingqin, College of Plant Science and Technology、Associate Professor Zhang Qing、Associate Professor Zhang Defeng has led members of the practice group to Guajiayu Village and Suziyu Village, Dahuashan Town, Pinggu District for many times，Yuzhen、Village leaders and technicians discuss the technical difficulties encountered in bagging-free management of Pinggu peach and candied dates planting in Suziyu，And propose solutions based on actual conditions。
As understood，Traditional Pinggu peach bagging technology has significant effects on reducing pests and diseases and increasing the commerciality of peach，has become a conventional technology for peach production。But this technology is labor-intensive and time-consuming、Abandoned fruit bags pollute the environment and other issues，In addition, in recent years, the number of people engaged in fruit tree management in rural areas has been decreasing，Resulting in "labor shortage" during bagging time。Cao Qingqin and Zhang Qing’s team focused on the pain points and difficulties of Pinggu’s peach industry，Develop, demonstrate and promote the labor-saving bagging-free technology system for Pinggu peach through the Science and Technology Institute and Doctoral Farm，Promote high-quality development of Pinggu peach industry。
Teachers and students of the practice group learned more about the cultivation and management of peach and the occurrence of major diseases and insect pests at the Tao Bagging-free Dr. Farm in Guajiayu Science and Technology Xiaoyuan，Explaining the bagging-free technology for large peaches to local technicians、Applications and advantages of microbial fertilizer，Conducted in-depth exchanges with local technical staff on the bet365 online sports bettingprevention and control of bacterial black spot and pear heartworm，In accordance with "combination of prevention and treatment、Principle of "precaution first"，Developed a green comprehensive prevention and control technology system for major pests and diseases。“Thanks to the experts from Beijing Agricultural College for providing us with professional technical guidance，brings us effective green prevention and control methods of pests and diseases。”Local fruit farmers express their sincere gratitude to the teachers and students of the school。
Suziyu candied dates were a "tribute" as early as the Ming and Qing Dynasties，is an excellent representative of “Beijing flavor” fruit，Loved by Beijing citizens。But due to the influence of cultivation management and pests and diseases，This breed has been on the verge of extinction in recent years、A jujube is hard to find。Local people urgently hope that school experts can help restore the breed。The teams of Cao Qingqin and Zhang Qing have helped Suziyu Village establish the Suziyu Jujube Germplasm Resource Garden and High-Yield Demonstration Garden in recent years，Protect and bet365 online sports betting mobilerestore Suziyu candied date resources，Help local fruit farmers increase their income and become rich。
With the strong support of the school’s Science and Technology Hospital and Doctoral Farm，Suziyu Village has established a high-quality production base of more than 50 acres of Suziyu candied dates，Laid the foundation for the restoration of high-quality development of Suziyu candied date industry。The practice group came to Suziyu Jujube Planting Base again during the summer，Investigating the cultivation and management of candied dates in Suziyu。“Due to less rain in the first half of the year and poor management，The survival rate of candied jujube seedlings resulting in colonization is not high。”The practice group put forward rational suggestions on improving the survival rate of candied dates and strengthening the cultivation and management of candied dates。“The teachers have repeatedly told the jujube base planting staff to strengthen orchard management，Irrigate during the critical water demand period for jujube tree growth，Increase survival rate。" A classmate from the practice group said with deep feeling，“Watching teachers provide technical guidance to fruit farmers，I just know why the local government and fruit farmers are so enthusiastic about us，I will learn more about professional knowledge in the future，Use new agricultural technology to contribute youthful energy to help the capital comprehensively promote rural revitalization。”
Provide step-by-step technical guidance to promote the development of understory edible fungi
Early August，The "Green Shade Bacteria" practice group of the College of Plant Science and Technology is led by Professor Zhang Guoqing、Led by teacher Zhang Weiwei, they arrived at Guajiayu Village Science and Technology Yard in Pinggu District to carry out summer social practice activities to help rural revitalization。
The practice group investigated the folk tourism in Guajiayu Village in recent years、Economic development under the forest。“During the survey, we discovered that the development of edible fungi under the local forest is weak、Lack of special souvenirs and other issues，We recommend taking advantage of local tourism resources，Carry out the cultivation of red matsutake under the forest，Create ‘flower viewing and mushroom picking’、Parent-child picking and edible mushroom souvenirs，Thus promoting the development of local cultural tourism and increasing farmers’ income。" Zhang Guoqing said。
The practice group also came to the collective forest farm of Longwantun Town, Shunyi District，Investigating the cultivation of bamboo fungus under the forest。Due to the large sowing area、Too much rain recently，There are some ridges with few mushrooms、Problems such as abnormal fruiting of bamboo fungus。"Teacher Zhang，There are no signs of mushrooms yet，Does it mean that the planting failed？”As soon as I saw the teachers and students of the practice group arriving，The technician came up and asked。Teacher Zhang Guoqing used his hands to remove the surface soil，Check the mycelium growth carefully，"No problem，Mushrooms come out sooner or later，This is normal，Mycelium is still growing，And in good condition，As long as it is managed properly，When the mycelium is full, mushrooms can be produced normally。”The technician heard the teacher’s answer，Said happily: "Then I'll be relieved，I have been worried about this for several days！”
In view of the problem of deformity during the opening process of bamboo fungus eggs，Teachers and students of the practice group recommend micro-spraying the cultivation bed machine for a short time before picking mushrooms in the morning，Increase air humidity，Help the bamboo fungus to open the umbrella smoothly。“The professionalism of bamboo fungus cultivation technology brought by bet365 online sports betting mobileBeinong teachers and students、Very targeted，I believe that under the guidance of experts，The bamboo fungus cultivation in the park will surely usher in a bumper harvest this year！" the base technician said happily。
Introduce disease and pest control classes to the orchard to make the "Buddha Sees Joy" pears even sweeter
This summer，The "Plant Hospital Workshop to Help Rural Revitalization" practice group of the School of Biology and Resources and Environment has visited Maoshanhou Village, Jinhaihu Town, Pinggu District for many times to conduct agricultural assistance classes，Carry out training on "Buddha Jianxi" pear pest control technology。
The unique geographical conditions of Maoshan Houcun provide a suitable growing environment for the "Buddha Jianxi" pear，Making "Buddha Jianxi" pear a pillar industry in Houcun, Maoshan。The practice group, led by teacher Ren Zhengguang, first came to the “Doctoral Farm” for green bet365 online sports bettingprevention and control of pear pests and diseases and professional management。Everyone carefully check the current growth status of pear trees，And diagnosed the pests and diseases found on site，Pear black spot discovered、Pear powdery mildew and numerous pear psyllid nymphs。“The damage caused by pear black spot is almost over，Powdery mildew will become the next major disease of pears，Watch powdery mildew when it first appears，Control it in time，In addition, the nymph stage of pear psylla is also a critical period for the prevention and control of this pest，Strengthening prevention and control at this time will achieve twice the result with half the effort。”Teacher Ren Zhengguang explained the key points of pest control to fruit farmers in detail。
The practice group came to Fojian Xili Science and Technology Yard in Houcun, Maoshan again，Carry out agricultural assistance classes focusing on green bet365 online sports bettingprevention and control of pear tree diseases and insect pests。Teacher Ren Zhengguang took the samples of pear tree diseases and insect pests collected on site as an example，Explained in detail the occurrence trend of pests and diseases during this period and the importance of controlling pests and diseases during the critical period。“The number of adult pear psyllids decreased in mid-July，Increased egg production，Is the critical period to control pear psyllid，Release the natural enemy ladybug card in the orchard，Hanging sweet and sour liquid on the pear tree、Trapping bags and insect sticky boards can effectively carry out physical trapping and killing。" Ren Zhengguang explained in detail。In addition, Ren Zhengguang also reminded the fruit farmers，The incidence of pear black spot is rising rapidly and requires urgent treatment，To prevent greater impact on the growth of pear trees。
“There are a lot of dead leaves in the orchard，Teacher Ren, please help me。”“The pear leaves in my orchard are turning yellow，The effect is not obvious after adding iron fertilizer，I don’t know what’s going on？”Ren Zhengguang answered one by one other questions raised by fruit farmers about pear orchard planting。“Dead leaves are caused by high temperature hazard，Called ‘Ye Shao’，It is recommended to pay attention to pruning，Increase air circulation。”“The soil pH in our area is relatively high，Not conducive to the absorption of iron in the soil，Therefore, if the leaves turn yellow, it is recommended to regularly spray ferrous sulfate on the leaves，The effect is better than iron fertilizer。”Ren Zhengguang gave detailed suggestions to fruit farmers，Students in the practice group also carefully recorded the key points of knowledge。
“Thank you very much, Teacher Ren，In one class, all the confusion we encountered during planting were answered。" The fruit farmer in Maoshan Hou Village said gratefully。
Next，The "Botanical Hospital Workshop Helps Rural Revitalization" bet365 online sports bettingpractice team will continue to carry out a variety of practical activities to support agriculture in Maoshan Hou Village，Improve the quality of "Buddhajianxi" pears、Fruit farmers increase their income and make greater contributions。
