- W2353996841 abstract "In this paper, climatic resources utilization coefficiency of cereal crops in China has been calculated for the first time, and a conception of heat utilization efficiency is developed. The utilization efficiency of light is 0.14%, that of heat is 0.87kg/(℃·d·hm 2) and that of precipitation is 5.25kg/(mm·hm 2) in cereal crops in China. The climatic resources utilization coefficiency of cereal crops have a great difference among regions, which is higher in the north than in the south. The utilization coefficiency of light, heat, and water have different features. The utilization coefficiency is high in regions where the quantity and distribution of light, heat, water meet the needs of crops. The conditions of light, heat, water and utilization coefficiency have an inhibitory effect with each other. Mulliple cropping has improved annual climatic resources utilization coefficiency. The measures to increase climatic resources utilization coefficency of cereal crops are described." @default.
