Preliminary analysis of the review on registration of microbial fertilizer
Microbial fertilizer enterprises need to obtain the fertilizer registration certificate.Analyzing the registration status helps to understand the development situation of the industry.The research reviewed the registration data of microbial fertilizers up to June 2022,and analyzed the types of the registered products,the number of enterprises,the regional distribution of enterprises and the microbial count of the products.In total,9 980 valid registration certificates were obtained by 3 478 enterprises covering nationwide.There were 3 categories,10 products and 3 forms of microbial fertilizers,the more products were microbial inoculants(48.1%),microbial organic fertilizers(29.3%)and compound microbial fertilizers(17.5%).In 2018,with the relaxation of policy,the microbial fertilizer industry expanded rapidly,with 3 794 registrations.Since then,more than 1 000 registrations have been registered yearly,accounting for 86%of the total registrations in the past five years.The microbial fertilizer industry distributed widely in Henan,Shandong,Heilongjiang,Hebei,Shaanxi,Liaoning,Hubei,Guangdong,Inner Mongolia,Guangxi and Xinjiang,with the number of enterprise and product accounting for more than 70%of the country.Only 3.1%of enterprises have obtained 10 or more registration certificates,with 35 certificates at most,while 84.7%of enterprises have only obtained 1 to 4.Most of the microbial count were less than 1 billion,with<1 billion-0.02 billion CFU·g-1accounting for 92.39%,<10 billion-1 billion CFU·g-1 accounting for 6.17%,<100 billion-10 billion CFU·g-1 accounting for 0.98%,and≥100 billion CFU·g-1 accounting for 0.46%.Bacillus subtilis,Bacillus amylolyticus and Bacillus licheniformis could produce 100 billion CFU·g-1 or more,the highest was Bacillus amylolyticus≥600 billion CFU·g-1,followed by Bacillus subtilis≥500 billion CFU·g-1.Taken together,the microbial fertilizer industry has entered a period of rapid and stable development,but most of the products are low in microbial count,and most enterprises have a single product category.Developing high-quality products with high strain count and high stability maybe a major way to occupy the market share of microbial fertilizer in the future.
