Development and Characterization of A Granular Compound Biofertilizer
摘要
Abstract
In order to reduce the application rate of chemical fertilizer, and to effectively use low-grade phosphate ore, we a?dopted microbes and urea to develop a granular compound biofertilizer ( GCB) . This GCB consists of 20% 80-mesh ground phos?phate rock containing 20% phosphorus, 50% urea, 10% calcium carbonate, 10% sodium carboxymethyl starch, 5% Bacillus amyloliquefaciens B9601-Y2, 5% Paenibacillus mucilaginosus K3, and 5% water; the effective bacterial quantity of this GCB reaches 5×106 CFU/g, and its particle diameter is about 0.3 cm. The results of pot experiment showed that: in comparison with the blank control without fertilization, applying this GCB could increase the root length, type height, and fresh weight of maize seedlings by 35.90%, 36.82% and 63.93%, respectively; as compared with using the granular compound fertilizer without mi?crobes and with 5% more urea, using this GCB also could increase the root length, type height, and fresh weight of maize seed?lings by 14.20%, 10.10% and 14.28%, separately. The GCB disintegrated easily in the soil with 10% more water content, and its two microbial strains were stable and could well colonize in red loam.关键词
