China Deploys Smart Tech and Post-Rain Field Management to Safeguard Autumn Harvest

Agricultural authorities across China are intensifying field management as autumn crops enter critical growth stages, according to state broadcaster CCTV. With autumn grain accounting for the bulk of national annual production, major farming regions are rolling out precision technologies, biological pest controls, and post-disaster remediation following recent heavy rains. Measures range from smartphone-controlled irrigation in Heilongjiang to the dispatch of over 10,000 technicians in Henan to guide crop recovery.

Autumn grain constitutes the majority of China's annual food supply, making crop performance in late summer critical to national food security targets. Effective pest control, efficient fertilization, and swift post-flood recovery in major agricultural hubs directly determine whether the country can maintain stable grain output despite extreme summer weather.

Agricultural regions across China are accelerating granular field management and post-disaster recovery efforts as autumn crops enter crucial stages of yield formation, according to state media reports. Autumn grain represents the largest portion of China's annual grain production. In northeastern Heilongjiang province, corn, soybeans, and rice have reached decisive growth phases. In Huanan County, local farms have introduced smart water gates linked to soil moisture sensors, enabling farmers to regulate field irrigation via smartphone applications. In northern Hebei province, where corn crops have entered the grain-filling stage—a period typically marked by peak pest and disease risks—local authorities in Handan's Yongnian District are pairing multi-benefit chemical spraying with biological controls, including the release of Trichogramma parasitic wasps to suppress crop pests. Technological adaptation is also under way in southwestern hilly terrain. In Liangping District of Chongqing, where standard machinery access is limited and fertilizer efficiency has historically been low, local partnerships with vocational colleges yielded integrated side-deep single-pass fertilization methods and nano-trace element fertilizers. The approach has cut fertilizer use by roughly 20 percent while boosting nutrient uptake. Following recent rounds of heavy rainfall that disrupted crop development in several central and southern provinces, local governments have mobilized targeted recovery interventions. In Henan province, 18 autumn grain expert advisory teams joined more than 10,000 agricultural technicians deployed to the field to guide farmers through crucial post-rain spraying operations. In Anhui province, authorities are carrying out drainage, top-dressing fertilization, and pest management. At Xiaogang Village in Fengyang County, an agricultural Internet of Things platform provides real-time data on soil moisture and pest dynamics to inform management decisions. Meanwhile, in Hengzhou, Guangxi, agricultural bureaus have deployed nearly 9,000 agricultural machines and implements to clear silted fields, unblock drainage ditches, and accelerate replanting. Local officials report that more than 56,000 mu (around 3,733 hectares) of farmland have been restored and over 37,000 mu (around 2,467 hectares) replanted.
