Autumn and winter around the corner, to strengthen the guidance of scientific application of fertilizers in autumn and winter crops, to improve fertilizer use efficiency, promote crop production and farmers income and sustainable development of agriculture, Ministry of Agriculture recently issued the "main crop in autumn and winter 2011, fertilization of scientific guidance."
 Science and the Ministry of Agriculture guidance fertilization Fertilization technical experts in autumn and winter according to the characteristics of major crops need fertilizer to soil testing and fertilizer research, based primarily on results of the project developed. It is for winter wheat, winter oilseed rape, vegetables, tea and fruit trees in autumn and winter the main problem crop fertilization, considering the characteristics of different regions of the soil, planting patterns and target output, sub-regional, sub-species fertilization made ​​a corresponding principle of fertilization number and fertilization methods.
 The Group recommends that all localities should focus on "promoting production, to mention the efficiency, safety," the three goals, the spirit of "yield fertilization, fertilization of economic, environmental fertilization" the unity of the concept, according to local conditions to determine the different regions, different crops, fertilization of economic rationality, optimize resource allocation and nutrient ratio fertilizer, select the appropriate period of fertilizer, improved fertilization methods. Meanwhile, we must adhere to the scientific combination of fertilization and soil fertility, increasing organic fertilizer to promote straw, cultivation and use of green manure, soil and soil fertility, improve soil aggregate output capacity.
