Abstract:

The study on the effects of perishable waste organic fertilizer on rice yield, growth and soil physicochemical properties was beneficial to the fertilizer utilization of perishable waste. The field experiments showed that the yield of rice in T1 treatment was higher than that of CK1 and CK2. When the amount of perishable waste organic fertilizer used in 667 m2 reached 2 500 kg, the rice yield decreased significantly. With the increase of perishable waste organic fertilizer application amount, soil pH value and organic matter content showed an upward trend. Compared with CK1 and CK2, the contents of alkali-hydrolyzable nitrogen and available phosphorus in T1 treatment were slightly lower, but the available nutrient content in T2 treatment was significantly higher. There was no significant difference between the total soluble salt content of soil in T1 treatment and CK2, and with the further increase of perishable waste organic fertilizer application amount, the contents of total soluble salt, sodium ion and chloride ion showed an obvious upward trend. The application of perishable waste organic fertilizer caused a decrease on the oil content of the soil. Overall, 1 000 kg was the optimal amount for perishable waste organic fertilizer in 667 m2 paddy field. This study provides a scientific basis for the utilization of perishable waste as fertilizer.
