1、 Actual date of visit

From August 12, 2019 to August 22nd, 2018.

2、 Basic information of visiting

With the approval of the people's Government of Henan Province (No. 0838 [2019] no.0838), a delegation of five persons is composed of tanjinfang (Professor of the Institute of resources and environment), guolingru (Professor of Plant Protection College), wumingyu (Lecturer of the Institute of resources and environment), liuxiaoguang (Lecturer of Plant Protection College) and zhaoman (Lecturer of Plant Protection College), From August 12, 2019 to August 22nd 2019, he visited Germany for 11 days of cooperation and exchange. The main task of this visit is to understand the development of agricultural machinery in Germany, the utilization of soil and water resources, and the application status and existing problems of chemical fertilizer and pesticide on important crops.

The first day, on August 12, 2019, at 12:35 noon, we set out from the capital airport and flew directly to Munich, Germany. We arrived at 18:20 p.m. on August 13, local time, and then transferred to Cologne. At 19:25 local time, we arrived at Cologne and took a bus to stay in the Hotel.

The second day, on August 13, 2019, I visited the University of Bonn, and visited the Institute of agriculture, chemistry and zoology of Bonn University. At the agricultural college, understand the Institute of crop science and resource conservation. Jens L, University of Bonn é Professor on introduced the development process and current situation of agricultural college, and introduced the construction of campus, classroom and related laboratory of Bonn University. He learned that the campus layout of German university is different from that of China, without obvious gate mark, no enclosure around the campus, and different departments and different places, rarely distributed in different campuses. Then Professor Tan JinFang, School of resources and environment of Henan Agricultural University, introduced the development process and current situation of the College of resources and environment of Henan Agricultural University and the College of plant protection. In the afternoon, I visited the University of Bonn University History Museum and Museum, and returned to the hotel at night.

On the third day, on August 14th, 2019, Professor Tan JinFang made a report on the efficient absorption and utilization of plant nutrients to the researcher of Agricultural College of Bonn University, and discussed with experts the geological types of Germany and the situation of the absorption and utilization of plant nutrition on different geological types of land. Professor guolingru of Henan Agricultural University discussed with experts the occurrence of arthropods. It was understood that Lepidoptera pests occurred in large corn fields and wheat fields in Germany, but the occurrence of spurring pests such as Planthopper and aphid was heavy, so it was necessary to control them by spraying insecticides several times, and Germany did not grow transgenic corn. Return to the hotel at night.

On the 4th day, August 15th, 2019, Professor guolingru discussed with experts and scholars of Bonn University the impact of global warming on plants, plant feeding insects and natural enemies, and made a report on green prevention and control of new invasive pest, Spodoptera, grass, and Spodoptera. Professor guolingru indicated that the grass moth had invaded many countries in China and Asia, The harm is very serious and the scope of the harm is gradually expanding, which has become an important pest in the world. Because of its strong migration and diffusion ability, it is also very possible to invade Europe in the future from the perspective of the migration route. It is suggested that relevant experts should do a good job in monitoring and early warning in time, and both sides can communicate with each other on the pest control work at any time. In the afternoon, I visited the Crop Science Laboratory of Bonn University, studied new technologies of high-quality crop variety cultivation and pest green prevention and control, and returned to the hotel at night.

On the 5th day, August 16th, 2019, teacher wumingyu discussed with the teachers of Bonn University new technologies and methods on improving soil fertility and crop nutrient absorption and utilization rate, and made a report on the research on wheat corn nutrition and fertilization. Jens L, University of Bonn é Professor on said that the German planting mode is one season a year, and the land will be abandoned in the second half of the year. In the afternoon, I visited the Agricultural Machinery Laboratory of Bonn University, exchanged and studied the production technology and usage methods of efficient and precise agricultural machinery, and returned to the hotel at night.

On the 6th day, August 17th, 2019, I visited the laboratory of Remote Sensing Center of land surface of Bonn University in the morning to exchange and learn remote sensing control technology for efficient and precise agricultural operation. In the afternoon, I visited the food chain and Network Research Laboratory of Bonn University, exchanged the research experience of both sides in crop pest natural enemy food network. It was learned that most areas of Germany could reduce the occurrence and harm of pests and pests by planting plants with biological diversity around corn planting in most areas of Germany. Return to the hotel at night.

Day 7, August 18, 2019, take a bus to Frankfurt. In the afternoon, we held academic exchanges with the German economic and cultural cooperation association to exchange views on the development trend of modern soil management and fertilizer. Return to the hotel at night.

On the 8th day, August 19, 2019, we visited the biology department laboratory of Frankfurt University, and conducted a group discussion with relevant experts on new technologies of soil health and fertilizer cultivation, discussed the current research status of the global plant nutrition research institute, and learned about the physiological use and treatment measures of salt stress on plants, and the influence of salt damage on soil structure. In the afternoon, I went to the laboratory of Biology Department of Marburg University, and studied the management, sharing and maintenance methods of the laboratory. Return to the hotel at night.

On the 9th day, August 20th, 2019, in the morning, we exchanged new technologies and new methods to realize efficient management of plant nutrients and precision agriculture with foreign countries. In the afternoon, he went to the federal crop research center in Germany to learn the advanced technology and methods of using plant genetic information to screen out the nutrient efficient genes in plants, so as to cultivate high-quality crop varieties. Return to the hotel at night.

On the 10th day, August 21, 2019, in the morning, a group discussion was held with experts in soil science and plant protection research field of German Federal crop research center on new ways and management methods for reducing fertilizer and pesticide application in crop production. In the afternoon, they set out from the hotel to the airport and flew back to Beijing by plane at 20:15 p.m.

On the 11th day, I arrived in Beijing at 11:25 on August 22, 2019, and then returned to Zhengzhou from Beijing Capital Airport to finish the investigation trip.

3、 Main achievements and gains

Germany, with a land area of 350000 square kilometers, is less than twice the area of Henan Province, with a population of more than 80 million. However, the agricultural land area is about 19million hectares, accounting for more than general land area. It is a highly developed modern industry, but still attaches importance to agriculture. Animal husbandry is very developed, and its output value accounts for more than 60% of the total agricultural output value. In terms of agricultural irrigation infrastructure, there is no special irrigation and water conservancy facilities. Germany has abundant rain and less sunshine, and there are many mountains and swamps, which is not conducive to cultivation, but is suitable for the growth of forage and other feed crops. Therefore, it is the best choice to plant forage and other forage crops and develop animal husbandry. In addition, the production structure mainly based on animal husbandry can greatly improve the added value of agricultural products. There is also a benefit of growing forage or other forage crops: it is beneficial to the protection of the ecological environment. German crops are quite small, mainly relying on several. The main crops are wheat, corn, potatoes, barley, etc. Corn is the largest area, mainly for the large number of livestock feed, so this piece can also be put on the animal husbandry. Another feature is that the vast majority of farms are both livestock and planting. Farm farm breeding cattle and sheep, using feces to produce a large number of organic fertilizer, manure used for fertilizer, applied to corn, alfalfa and other feed crops; Corn, alfalfa and other crops are used to feed livestock. Form a good ecological industrial chain. In addition, because Germany is in the center of the EU and the transportation logistics is highly developed, the transport vehicles in EU countries can be unblocked, so a large number of cold and fresh vegetables are supplied from other countries in the EU.

4、 Inspiration and work suggestions

Germany is highly industrialized, but still attaches importance to agriculture, with high forest coverage. There is no significant difference between urban and rural areas in terms of forest coverage and environment, and ecological livable. More importantly, Germany attaches great importance to education and has deepened the people's hearts in Germany to improve the modernization of education. As an agricultural scientific researcher, he has learned new research methods from advanced scientific research abroad, broadened the research ideas and raised the innovation consciousness. Through exchange of visits and learning, the experience and technology at home and abroad, combined with their own scientific research actual situation, will be transformed into relevant research topics.
