摘要： 近年来直播水稻在江苏等地区扩展迅速，但其栽培和育种的专项研究很少。本研究对江苏省苏中地区直播稻生产力水平进行了调查，在此基础上进一步实施水稻直播栽培模式下氮肥施用量和运筹比例试验，探讨直播水稻群体生长和产量形成对氮肥施用的反应特征。调查结果显示，苏中地区普通农户直播水稻的产量平均为7 710 kg hm-2，显著低于机插和人工移栽稻，直播稻氮肥施用量一般在270 kg N hm-2之上，氮肥不合理施用的现象普遍存在。小区试验表明，施氮量和氮肥运筹比例均对直播稻产量有显著影响，氮肥施用量主要通过有效穗数和每穗粒数对产量发挥作用，而氮肥运筹比例主要对每穗粒数产生影响。在本试验条件下，氮肥施用量270 kg N hm-2，基肥∶分蘖肥∶穗肥=4∶3∶3的产量最高。在上述施肥条件下，直播水稻群体结构较为合理，个体和群体的物质生产量均处于较高水平，结实期物质生产能力较强，经济系数表现合理的较高水平(0.53左右)，同时有相对较好的抗倒性能。对直播水稻的增产途径和高产群体特征进行了较深入的讨论。

Abstract: In recent years, cultivation area of direct-seeding rice in Jiangsu and nearby regions has been expanding rapidly, but the specific research on cultivation and breeding is very little. In this study, based on investigation of the productivity levels of direct-seeding rice in central Jiangsu province, we carried out a test of nitrogen application amount and nitrogen application ratios for direct-seeding rice, to explore the response of dry matter growth and yield to nitrogen fertilizer application. The result showed that, the average yield of direct-seeding rice in central Jiangsu province was 7 710 kg ha-1, which was significantly lower than that of mechanical and manual transplanted rice; the nitrogen fertilizer rate was generally more than 270 kg N ha-1, and the unreasonable application of nitrogen was widespread. Plot experiments showed that the application rate of nitrogen affected yield through panicles per unit area and spikelets per panicle, while the application ratio of nitrogen mainly had influence on spikelets per panicle. In the experimental condition, the highest yield was gained when the nitrogen rate was 270 kg N ha-1 and the ratio of basal : tillering : panicle was 4:3:3. When the fertilization is in the optimum conditions, the direct-seeding rice will have more reasonable population structure, higher dry matter production capacity both for individuals and population, more suitable harvest index (0.53 or so) and higher resistance to lodging. The pathway to increase yield and the characteristics for high-yielding direct seeding rice population were also discussed.
