In Heilongjiang, China"s largest grain-producing province, autumn harvesting is underway. Its overall farm planting and harvesting mechanization rate has led the country for years, surpassing 99 percent. Widely seen as a cornerstone of national food security, the province is rolling out new technology to boost per-hectare yields and crop quality.

　　The province deployed over 25,000 precision seeders and 33,000 crop-protection drones this year to lift farm operation standards and efficiency, said Zhu Huasheng, deputy director of the provincial agriculture and rural affairs department.

　　Official figures also show Heilongjiang has dispatched more than 26,000 agricultural officials and experts to the fields so far this year, guiding farmers to adopt new technologies.

　　Cheng Guoqiang, dean of the National School of Food Security Strategy at Renmin University of China, said that in a year of tightening global grain supplies, China"s steady grain production has helped stabilize global market expectations.
