Abstract:

Since the 1990s, the application of chemical fertilizers in China (excluding Hong Kong, Macao, Taiwan, the same as below) has shown a trend of continuous growth. In 2016, there was a negative growth for the first time, but the application intensity of chemical fertilizers did not substantially decrease. Currently, the application intensity of chemical fertilizers in China is still higher than the international safety standard. Based on the analysis of the current status of chemical fertilizer application in China, a factor decomposition model was introduced to scientifically analyze the relationship within structure share, efficiency share and changes in chemical fertilizer application intensity from two aspects of high-fertilizer crops and high-intensity areas. The results showed that the application amount and intensity of chemical fertilizer in China were on the rise as a whole in 1990-2018. The difference in planting structure within regions was one of the important reasons for the regional differences in chemical fertilizer application intensity. At the aspects of high-fertilizer crops, the biased planting structure toward fruits and vegetables was the leading factor for the increase of chemical fertilizer application intensity, and the structure drive rate reached 66.74%. At the aspect of high-intensity areas, the structure share and efficiency share both contributed to the increase of chemical fertilizer application intensity. However, the efficiency drive effect has increased since 2017. Factors, such as the level of economic development, agricultural labor transfer, and the urbanization development level had significant (P<0.1) impact on the chemical fertilizer application intensity. Therefore, more efforts should be devoted to the adjustment and optimization of planting structure by reducing the sowing area of high-fertilizer crops, as well as the improvement in the utilization efficiency of chemical fertilizers via promotion of fertilizer-saving technologies, to reduce chemical fertilizer application intensity in the future.

Key words: fertilizer application intensity, factor decomposition, structure drive rate, efficiency drive rate, control path
