摘要：

为探究不同土壤条件下连作晚稻的科学施肥方案,以甬优1540为试验材料,设置6种处理:不施肥(CK)、无氮区(N0P1K1)、无磷区(N1P0K1)、无钾区(N1P1K0)、配方肥区(N1P1K1)和缓释肥区(NHPHKH),并在两种典型土壤试验地开展研究。结果表明,高肥力试验地中连作晚稻的产量高于低肥力试验地。缓释肥处理(NHPHKH)在高、低肥力试验地均能提高水稻产量和肥料利用率。其中,在低肥力试验地中该处理效果尤为显著,不仅进一步提高了肥料利用效率,还增加了净收入。研究为优化连作晚稻化肥施用方案提供了参考。

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
