Organic fertilizer is a high-tech green fertilizer produced by biological fermentation and aging with livestock manure and straw powder as main materials.It has high content of organic matter and no heavy metals.It can effectively alleviate the hardening state of soil and improve the ability of soil to retain water and fertilizer.In order to promote the large-scale application of organic fertilizer instead of chemical fertilizer in field crops,the agriculture and rural Bureau of Lingbi county has established relatively fixed experimental demonstration bases in some towns and townships.Through the application of formula fertilizer,commercial organic fertilizer and other new fertilizers,the implementation of formula fertilizer and simultaneous sowing of seed fertilizer have been promoted,and gradually mastered the new technology of reducing and increasing efficiency of organic fertilizer instead of chemical fertilizer suitable for local soil moisture.At the same time,we will adopt the method of"two unification,two reduction and two improvement".The government will invite tenders for professional organic fertilizer production enterprises to uniformly directly supply organic fertilizer to the experimental demonstration field,and the socialized service organization will uniformly apply fertilizer to the experimental demonstration field,so as to more efficiently reduce the use of chemical fertilizer in the experimental demonstration plot,reduce the labor cost of applying organic fertilizer and enhance the farmers'awareness of increasing the application of organic fertilizer.
Since this year,Lingbi county has continued to promote the implementation of chemical fertilizer reduction and efficiency increase-experimental demonstration of organic fertilizer instead of chemical fertilizer,involving 16000 mu of farmland in 2 villages and 5 large grain growing households in the county.As this year's project demonstration area,the new fertilization standard is adopted for the autumn planting of 11000 mu of wheat crops in Hewang village.100kg commercial organic fertilizer is applied per mu,reducing the use of chemical fertilizer by more than 20%.
Up to now,Lingbi county has promoted the development of 30000 mu of organic fertilizer instead of chemical fertilizer demonstration area.Compared with conventional farmland,the demonstration area reduces the annual amount of chemical fertilizer by nearly 600000 kg on the basis of no increase in cost and no reduction in benefits.Driven by the demonstration area,the county will condense and form the technical standard for increasing the application of organic fertilizer in the field,which will be popularized and applied in the whole county to promote the development of green ecological agriculture.
