“Soil is one of the most important natural resources on earth。It not only provides a basis for plant growth,It also has an important impact on environmental quality and human health。”

“Due to the influence of factors such as human activities and environmental changes,Soil environmental quality faces severe challenges。Carry out soil survey,Test soil quality,For protecting soil resources、It is important to maintain ecological balance and human health。”

……

Recently,dafabet mobile loginStudents from several primary and secondary schools in Xi’an experienced the entire soil survey process,"Physical examination" of soil,Many students also wrote down their understanding of soil and soil census in their notebooks。

This is a project sponsored by Shaanxi Land Engineering Construction Group、Soil census scientific inquiry activity jointly organized by Xinhua·Oriental Jiahe Labor Education Practice Base and Shaanxi Institute of Biological Agriculture,Divided into two stages: soil field sampling survey and soil sample testing and analysis。

May 9,137 students came to Fuping Pilot Base of Provincial Land Construction and Land Engineering Technology Research Institute,Participate in Soil Science Salon、Soil field sampling survey、Sample preparation and testing and other science popularization activities,Learn scientific knowledge related to soil census,And experience the scientific research process of soil testing under the guidance of experts。

In the first stage of inquiry activities,Provincial Institute of Biological Agriculture、Experts from the Provincial Land Construction and Land Engineering Technology Research Institute explained to the students the ins and outs of collecting soil survey profile samples,Analyzed soil profile structure and properties。Through these explanations,Students better understood the connotation of soil science,Recognize the great practical significance of carrying out soil census。

After,Expert、The teacher organized the students to go to Lubo Beach,Strictly follow the layout、Clear table、Dig a hole、sampling、Mixed sample、Diminished sample、Division of labor and cooperation in weighing and other aspects,Complete soil field sampling survey。After the soil field sampling survey is completed,They sent the collected soil samples to the preparation center for air drying,Complete the first stage of soil survey。

This period,The third national soil census is in full swing across the country。Soil census scientific inquiry activities can give primary dafabet mobile loginand secondary school students a more in-depth understanding of soil and soil census。

“Experience Soil Census,Carrying out soil survey scientific research activities with the theme of “Concerning Land Security”,The purpose is to promote soil census,Popular soil knowledge,Guide students to establish environmental protection concepts,Increase their awareness and understanding of soil ecosystems,Cultivate their practical ability and scientific literacy。" said Sun Xubo, director of the testing company of the Provincial Land Construction and Land Engineering Technology Research Institute,“This soil census scientific research activity,This is a rare social practice for the students,It is their first time to participate in soil census。I believe that through such activities,Children will have a new understanding of the scientific study of soil。”

May 14,Students follow different testing index requirements,Preparation of collected soil samples。After completing the basic experimental assessment,They took these soil samples to the laboratory for testing,And recorded the detection data one by one。

“Conversation with Scientists,Experience the whole process of the third national soil census,Systematic learning standard experimental operations,Participate in sample testing in the laboratory,Home、School、Base collaboration completed soil survey,is the highlight of this event。" Sun Xubo said,"At this event,Students showed interest in soil testing and enthusiasm for the field of environmental science。They asked many probing questions about the testing process and possible results,It also allows us to see the power of science popularization!”

"Organically integrate national basic science engineering and youth science education,is an innovation of this event。We hope that through such activities,Teaching scientific knowledge、Scientific method at the same time,Let students deeply understand the methods of agricultural scientific research,Inspire their interest in agricultural dafabet loginscientific research。" said Li Bo, deputy director of the Provincial Institute of Biological Agriculture。

After the end of the soil survey scientific research activity,Students participating in the activity presented wonderful scientific inquiry reports in groups,And received the honorary certificate of "Little Soil Census Investigator"。

"Through this event,We have personally practiced seeking truth and being pragmatic、Normal and rigorous scientific methods。From field sampling to soil available phosphorus、Quick-acting potassium、Organic matter detection,Social practice has brought me many new experiences、New Harvest。" said Li Yinuo, a student at Xi'an High-tech Zone Experimental Primary School。
