为加强春季作物科学施肥指导,农业部测土配方施肥技术专家组结合主要农作物需肥特点,以测土配方施肥项目成果为主要依据,研究制定了《2011年春季水稻科学施肥指导意见》。总体原则是:各地要因地制宜确定不同区域、不同作物经济合理施肥量,优化施肥时期,采用科学施肥办法,提高肥料利用率;鼓励多施有机肥料,倡导秸秆还田,改良土壤,提高土壤综合产出能力;突出今年春季干旱少雨特点,有针对性合理调控水肥管理,以肥促水,提高作物抗旱能力。
In order to strengthen the guidance of scientific fertilization in spring crops, the expert team of the Ministry of Agriculture on soil testing and formulating and fertilization combined with the characteristics of main crops needing fertilizers and based on the results of the soil testing and fertilization project, formulated the Guidance on Rice Scientific Fertilization in the Spring of 2011. The overall principle is: to determine the appropriate measures to local conditions in different regions and different crops, the amount of fertilizers and economic optimization, the optimal fertilization period, the use of scientific methods of fertilizers to improve fertilizer utilization; encourage more organic fertilizer, and advocate the return of straw, soil and improve soil comprehensive yield Out of capacity; highlighting the characteristics of this spring drought drought, water and fertilizer management targeted and reasonable to fertilizer to promote water and improve drought tolerance.
