In order to reduce the decline of soil fertility caused by excessive application of chemical fertilizer and agricultural non-point source pollution, the Ministry of agriculture has determined the goal of zero growth in fertilizer use from 2016 to 2020. A year ago, to promote the situation from the reality in some places, although also formulated the "action plan for fertilizer zero growth, but due to the lack of effective and strong measures, the actual agricultural production decrease fertilizer effect is not obvious. Therefore, the author believes that the government in promoting "fertilizer zero growth" should be closely combined with practical work, the local agricultural production, implement Duocuobingju, make "fertilizer zero growth" to achieve real results.
First, it is necessary to guide farmers scientific fertilization. From the current situation of agricultural production in some areas, due to publicity is not in place, fertilizer zero growth has not yet formed an atmosphere, but not the hearts of the people. Farmers farming fertilizer is still based on experience, go with the flow, the amount of chemical fertilizer is not reduced, but there are some varieties of fertilizer consumption has increased. In this regard, the agricultural technology extension departments should be based on the actual agricultural production around, vigorously promote the zero growth of fertilizer, the purpose of the same time, to strengthen technical services. Through technical means fertilization, scientifically determine the reasonable amount of fertilizer for main crop production, so as to provide important reference data to reduce the amount of chemical fertilizer for farmers, to guide farmers to purchase fertilizer, scientific fertilization, fertilization and scientific diet".
Two is to do a good job of experimental demonstration. According to the local main crops production to reduce the amount of fertilizer experiment demonstration, through the "slimming" plots compared with conventional fertilizer plots, let the farmers experience "lose weight" experiment field, the demonstration field results in the harvest, to truly feel the ground to reduce fertilizer and reduce crop yield, which can reduce cost and to increase efficiency, but also improve the quality of crops. With the results of experimental demonstration to promote zero growth of fertilizer, so that the majority of farmers are able to consciously respond to and participate in the zero growth of fertilizer national action.
Three is to focus on policy guidance. The government should encourage the introduction of a "zero growth in the process of chemical fertilizer in action" support policies to encourage and support farmers, farmer cooperatives and family farms timely application of organic fertilizer and biological fertilizer, organic manure and fertilizer such as subsidies, to fully mobilize the enthusiasm of farmers to participate in the "fertilizer zero growth" the real action, let "lose weight" become the conscious action of the farmers. Agricultural Technology Extension departments should be combined with the actual agricultural production, focusing on the promotion of local crops recommended for the growth of organic fertilizers, new fertilizers and bio fertilizer, in order to boost the zero growth of fertilizer action.
