Effect of Slow-release Fertilizer Side Bar Fertilization Technology on Rice Yield and Nitrogen Use Efficiency
摘要
Abstract
A field plots experiment was conducted to study the effects of side bar fertilization technology on rice yield and nitrogen use effi-ciency. The results showed that side bar fertilization technology based on high quantity of slow-release fertilizer treatment (HF)reduced the amount of nitrogen applied by approximately 40%compared to conventional fertilizer treatments (FP)but had no remarkable effects on rice yields while the number of ear of rice increased 8.36%. Side bar fertilization technology significantly increased rice nitrogen uptake and par-tial factor productivity from nitrogen applied (PFPN), reducing the apparent loss of nitrogen. Side bar fertilization technology treatment PFPN was between 39.1 and 67.8, significantly higher than the 23.7 of FP treatment. Apparent N losse of FP treatment was 174.2 kg·hm-2 and each side bar fertilization technology treatment was between 23.2 kg·hm-2 and 61.9 kg·hm-2. Considering the rice yield and environmental factors, side bar fertilization technology based on slow-release fertilizer was one of environment-friendly technology that can be applied.关键词
