Multi-pronged approach is needed to achieve zero growth of chemical fertilizers

"To implement the'zero growth' goal of chemical fertilizers, we must first establish the concept of'increasing production, fertilization, economic fertilization, and environmentally friendly fertilization.
, High-quality environmental protection, sustainable development.
The key work is to promote soil testing and formula fertilization, promote the application of new fertilizers and new technologies, and steadily improve the quality of cultivated land.
" Such important information.
??? Xin Jingshu, director of the Soil and Fertilizer Division of the National Agricultural Technology Extension Service Center of the Ministry of Agriculture, said at the forum that the current application of chemical fertilizers in China is that the average rate of fertilizer application per mu is relatively high, the uneven fertilization phenomenon is prominent, and the utilization rate of organic fertilizer resources is low.
Fourth, the fertilization structure is not balanced.
Heavy chemical fertilizers, light organic fertilizers, heavy macro-element fertilizers, light medium and micro-element fertilizers, heavy nitrogen fertilizers, light phosphorus and potassium fertilizers have prominent problems of "three heavy and three light".
Xin Jingshu said that the key tasks for achieving "zero growth" of chemical fertilizers must first continue to deepen the soil testing and formula fertilization, and expand the scope of implementation of soil testing and formula fertilization; secondly, it is necessary to strengthen the connection between agricultural enterprises of soil testing and formula fertilization, and fully mobilize the enthusiasm of production and distribution enterprises; Third, we must innovate service mechanisms, extensively mobilize economic cooperation organizations, large farming households, family farms, and cooperatives to take the lead in promoting the transformation of fertilization methods.
The application of new fertilizer technologies such as humic acid fertilizers, slow and controlled release fertilizers, flushing fertilizers, and foliar fertilizers, integrates and promotes high-efficiency fertilization technology models; fourth, we must vigorously promote the use of organic fertilizer resources, and encourage farmers to use farm manure and commercial organic fertilizers.
Fertilizer, promote the return of straw nutrients to the field, and plant green manure according to local conditions.
??? Bai Youlu, a researcher at the Institute of Agricultural Resources and Regional Planning of the Chinese Academy of Agricultural Sciences, pointed out that to achieve scientific fertilization, we must first have high-efficiency and scientific fertilizer products.
High-efficiency fertilizers should include appropriate nutrient content, appropriate nutrient ratio, and appropriate nutrient content.
Nutrient forms, suitable fertilizer additives.
Take fertilizer additives as an example, which can not only improve and affect the conversion of fertilizer nutrients, but also improve plant growth.
