Abstract:

To investigate scientific fertilization strategies for continuous cropping late rice under different soil conditions, a field experiment was conducted using Yongyou 1540 as the test material. Six fertilization treatments were established: no fertilization (CK), nitrogen-free (N0P1K1), phosphorus-free (N1P0K1), potassium-free (N1P1K0), formula fertilization (N1P1K1), and slow-release fertilizer (NHPHKH), in two typical soil experimental sites. The results showed that the yield of late rice was higher in the high-fertility soil than in the low-fertility soil. The slow-release fertilizer treatment (NHPHKH) increased both grain yield and fertilizer utilization efficiency in both high- and low-fertility soils. Notably, the effect was more pronounced in the low-fertility soil, where it further enhanced fertilizer efficiency and improved net income. This study provides a reference for optimizing fertilization strategies for continuous cropping late rice.

Key words: late rice, Yongyou 1540, slow-release fertilizer, fertilizer utilization efficiency, soil fertility
