Zhu Lizhi was invited to give a report at the academic conference on the quality and safety of agricultural products in the Asia-Pacific region.

On November 29, 2014, at the "Asia-Pacific Agricultural Product Quality and Safety Collaboration Network and Agricultural Product Quality Improvement Symposium" hosted by the International Cooperation Department of the Ministry of Agriculture and the International Cooperation Bureau of the Chinese Academy of Agricultural Sciences, the Institute of Agricultural Economics and Development of the Chinese Academy of Agricultural Sciences Researcher Zhu Lizhi, director of the Resources and Environmental Economics Research Office, was invited to give an academic report.

Researcher Zhu Lizhi's report is entitled "Theoretical Analysis of the Quality Improvement of Agricultural Producing Areas". The report believes that the continuous increase in the output of grain and other agricultural products for many years should indeed be a joy for a country with a large population like ours. However, we must also see how much we have paid for the quality of arable land behind the "continuous increase in agricultural products. In order to make every effort to increase production, China applies a large number of chemical fertilizers and pesticides every year, which makes the scarce cultivated land resources subject to predatory management for a long time: the production promoted by chemical fertilizers has drained the organic matter of the land; The production guaranteed by pesticides has injected more and more toxins into the land. A large number of chemical fertilizers and pesticides have caused serious damage to the soil microbial community, resulting in poor soil nutrient circulation and deterioration of physical and chemical and chemical properties.

Zhu Lizhi stressed that as early as three hundred years ago, the British economist William. Pi said that "land is the mother of wealth, and labor is the father of wealth". This sentence, especially for Chinese people who have a small per capita arable land area, should always be kept in mind. It is hard to imagine how far our "continuous increase of agricultural products" can go on the road of predatory land management.

Zhu Lizhi comprehensively stated in the report that to solve the problem of sustainable agricultural development, the focus should be on the land: the problem of low soil organic matter must be solved, the soil microbial community must be restored, and toxic components in the soil must be reduced....... If the soil problem is solved, it is not terrible that the growth rate of agricultural products is small, because "the strength is hidden in the ground, and the heart is confident." We can not only get agricultural products from high-quality cultivated land, but also ensure the quality and safety of agricultural products.
