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%。

关 键 词:水稻  精量穴直播  产量  生育特性

Abstract:Growth and development characteristics and yield formation of the rice of precision hill-drop 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 ea...
Keywords:rice  precise hill-drop drilling  yield  growth characteristics
