The activity of microorganisms in the soil can be adjusted through the application of stabilized fertilizer. Using biochemical means, the transformation of nitrogen in the soil is controlled, synchronizing the peak of nutrient released from soil and the peak of nutrient absorption by rice. With the application of stabilized fertilizer, the fertilizer utilization rate and the income of farmers can be improved and the environmental pollution can be cut down by reducing the amount of nitrogen fertilizer and decreasing the frequency of fertilization. This paper summarizes the application effects of stabilized fertilizer on different cultivars of rice in different regions for many years, and puts forward the issues to be concerned in the application of stabilized fertilizer with reduced amount and frequency and efficiency improvement techniques. |
