摘　　要：采用机械精量穴直播、人工撒播和人工手插种植方式对比,研究了机械精量穴直播条件下水稻的生育特性和产量形成特性。结果表明:机械精量穴直播有利于加快水稻的生长发育进程,缩短水稻的生育期,提高其生物学产量和叶面积指数,降低主茎总叶龄;机械精量穴直播稻的分蘖势较强,分蘖叶位低,分蘖发生和分蘖高峰出现早,单位面积的分蘖总量较大;机械精量穴直播稻每平方米有效穗263.63,比人工手插和人工撒播分别提高了24.63%和15.25%,机播的实际产量最高,较人工撒播和手插处理分别增产14.92%和4.59%。Growth and development characteristics and yield formation of the rice of precision hilldrop drilling were studied comparing with manual spreading,manual transplanting. Results showed that precision hill-drop drilling shortened the total growing period of rice, improved individual and the biological production area index, and reduced the total leaf age of the main stem. The tiller of precision hill-drop drilling was strong and powerful, low-leaf tiller, tiller occurred early and the peak of tillering appeared early,and the total tiller per unit area increased as well. Effective rice panicle of precision hill-drop drilling was 263. 63 panicles per m^2, increased by 24. 63% and 15. 25% more than manual spreading and transplanting,and its actual yield was 14. 92% and 4. 59% higher than manual spreading and transplanting, respectively.
