Formula Screening of Bioactive Fertilizer and Effects of Fertilizer on Physical and Chemical Properties of Soil and Economic Benefits of Maize
The formula of bioactive fertilizer and its effects on the physical and chemical properties of soil and economic benefits of maize was studied using field test in the Hexi Corridor light irrigation desert soil of Gansu Province. The results showed that the optimum proportion of biological active fertilizer was as follows:functional improving soil agent was 0.12 tons
bacterial manure was 0.09 tons
and biological active fertilizer was 1.20 tons. There was a positive correlation between fertilization quantity and soil porosity
aggregate structure
water contents
saturated water content
botanical traits
the economic characters and yields of maize. In addition
There was a negative correlatation between fertilization quantity and bulk density
pH value. According to regression analysis
the optimal economical application rate was 1.8 t/hm2
