Prof. He Hongbo, researcher of IAE and core member of the "Dry Land Soil Conservation and Production Capacity Improvement" Project, delivered a working report on behalf of the project team. She said that the conservative tillage model established by the project team can make full use of soil moisture and fertility during the cropping season and promote production efficiency of the soil, thus can better use and protect black soil resources and increase grain yields. By setting up a Changtu Model to popularise this efficient and environmentally friendly way of farming for dry land soil conservation, the development of modern agriculture in Liaoning will be greatly enhanced. 

Zhang Jun, deputy director of the Modern Agriculture Service Center in Changtu County, Prof. Xie Hongtu of the project team, and associate Prof. Bao Xuelian showed soil profiles and crop fields to Zhang Jiabao and other visitors. The improvements in soil quality, soil function and corn yields made all visitors truly realise the importance of studying and popularising the tillage model for black soil conservation. 

Academician Zhang Jiabao fully affirmed the work done by researchers of IAE in Changtu demonstration area. He pointed out that the research team is supposed to develop multiple modern agricultural models for black soil conservation and utilisation in order to achieve large-scale, green and intelligent agriculture. He encouraged the researchers to strengthen exchanges and cooperation with the local government, and to provide strong support for China's agricultural modernisation and rural revitalisation in the new era.
