In view of the present situation of unclear fertilizer application and the changed fertilizationaffect of Nenjiang County, through methods of fertilization investigation and statistical dataanalyses, study the situation and main problems of fertilizer application in Nenjiang County, andputs forward measures of fertilizer application:The main problems of fertilizer using in Nenjiang County: first, the blind fertilization. Aregional imbalance of fertilization and fertilizer ratio; secondly, formula fertilization by soiltesting technology is not in place, the nitrogen and phosphorus rate is very low. Lack of fundsand laboratory equipments could not be promoted timely, which affected the normal work, it wasdifficult to understand the change of soil nutrient accurately and to makescientific formulate fertilization scheme; third, lack of macroeconomic regulation and controlcountermeasures of fertilizers application; fourth, it did not adjust the amount of fertilizers due todifferent kinds of crops and their fertilizer characteristics; fifth, it did not pay attention to the traceelements and organic fertilizer. Large amounts of trace elements were removed from soil togetherwith food crops, if not be supplied timely, trace elements in cropland soils will be lacking andbecome a limiting factor for crop yield; sixth, lack of knowledge of scientific fertilization.Nowadays, farmers have already known the importance of scientific fertilization; let morepeople learn the basic principle of plant nutrition and fertilizer, to avoid many misunderstandings.Measures of reasonable fertilizer application of Nenjiang County: first, to develop andpopularize soil testing and formulated fertilization and balanced fertilization; second, to strengthenthe monitoring and survey of soil and fertilizer, to fertilize scientifically. To strengthen soilmonitoring, investigation and evaluation of the quality of cultivated land and to carry outthe investigation and rectification of fertilizer market; third, to adjust the structure and method offertilization, and increasing the comprehensive utilization rate of fertilizer; fourth, strengtheningmacro-control; fifth, to improve the fertilization technology and increasing the utilization rate offertilizer. |
