| 摘 要： | 为探明南方丘陵区粳稻种植中适宜的缓控释氮肥种类和合理的用量,本研究以普通尿素为对照,分析比较了2种包膜尿素(树脂包膜尿素和水溶性聚合物包膜尿素)不同用量下粳稻产量和肥料利用率的变化,并结合成本投入评估了不同处理的收益。结果表明,与普通尿素相比,施用缓控释肥显著提高了南方丘陵区粳稻产量、氮肥农学效率和收益,其中水溶性聚合物包膜尿素是较好的缓控释肥种类,适宜用量为195 kg/hm2(纯N)。

Effects of Different Type and Amount of Slow-release Nitrogen Fertilizer on Yield and Eco-nomic Benefit of Japonica Rice in South China |

| Abstract: | In order to define the reasonable type and amounts of slow-release nitrogen fertilizer on japonica rice in Southern hillside area, the authors analysised the yield and fertilizer use efficency of two kinds of slow-release nitrogen fertilizer with different coating materials(resin coated urea and water-soluble polymer coated urea), and assessed the inputs and benefits of different treatments, tak-ing common urea as control. The results showed that slow-release fertilizer significantly increased rice yield, agronomic efficiency and economic benefit, compared with common urea. The water soluble polymer coated urea is a better kind of slow-release fertilizer in Southern hillside area, and the best application amount was 195 kg/hm 2. |
