Synchronization technology for disaster prevention and yield enhancement of wheat in Yanhuai and Huaibei of Anhui
HU Chengli · Anhui Nongye Daxue xuebao · 2014
Poor seedling standing due to drought during the seeding time(around mid October), freezing and chilling injury in winter and spring, disease infection induced by spring rain, and lodging caused by tornados and other climatic hazards are main factors, largely limiting the yield increase of wheat in Yanhuai and Huaibei, the main wheat production region in Anhui. Management methods including optimizing the layout of varieties, using weak winter wheat varieties, early seeding in the moist soil and reducing seeding rate, using normotopia deep fertilization rather than surface application, aggravating jointing fertilizer, and straw returning in summer and autumn to improve the Shajiang black soil structure and fertility were presented in this paper. Some key innovations including the development of multifunctional agriculture machinery that can be used for straw returning, rotary tillage, normotopia deep fertilization, and sowing with compacting function have been applied in a large area of high yield wheat field in 8 counties(districts). The Synchronization Technology has led to the achievement on preventing natural disaster and increasing wheat yield and will have significant impact on increasing yield and economic benefits in the future.
