为提高宁波市水稻种植生产机械化水平,实现节本增效,选用常规稻宁84,在余姚阳明街道丰乐村开展分精量穴直播1、分精量穴直播2、人工撒播、机械插秧四种种植方式试验对比.通过播种效率,成本,水稻长势与产量的比较,结果表明,穴直播方式优势明显,播种成本相比人工撒播低3倍左右,相比机插秧低7倍左右;作业效率相比人工撒播作业效率提高20倍以上,比机插秧提高1.5倍左右;相比人工撒播没有耗时的起沟环节,相比机插秧,没有育秧麻烦环节,省工省时;经济效益相比人工撒播收入增加25%以上;相比机插秧收入增加5%以上.依据试验,对穴直播中的品种选取、耕整地、播种量、播种期等方面应注意的问题做了总结.

为了解黑龙江省直播稻的发展状况,根据生产调研,论述了黑龙江省水稻直播栽培技术的应用现状和成因,总结了直播稻发展中存在的问题,提出了水稻直播栽培技术发展的建议和对策,即加强水稻直播高产配套技术研究及水稻直播技术的引进和示范.现阶段的水稻直播栽培技术是在目前特定生产条件下形成的新的种植方式,具有劳动工效高、生产成本低等优点,但也存在直播稻主导品种不明确、主推技术不配套、病虫草害防治技术不到位等问题。
为了探索鸭稻共作技术在东北冷凉地区的可行性,本文在新宾县永陵镇郝家村试验研究了该技术对水稻生长性状和经济效益的影响.研究结果表明,鸭稻共作能促进水稻植株生长,增加有效分蘖,进而增加水稻产量,提高经济效益.鸭稻共作与普通插秧相对比,分蘖末期水稻株高提高8.83%;孕穗期,地上生物量、地下生物量、有效分蘖率分别提高9.59%、17.74%、25.4%;水稻单位面积穗数提高3.96%,每穗粒数增加1.0
为了进一步探索水稻旱穴直播技术在东北冷凉山区的适应性、节省成本和春季水资源,在新宾满族自治县,以机械插秧为对照,采用2BD-H10型水稻精量旱穴直播机播种,试验研究了旱穴直播对水稻生长性状、产量和效益的影响.试验结果表明,与机械插秧相比较,旱穴直播水稻的生育期较短、出苗率较低,平均叶龄减少了0.8片叶,生育期缩短了3d,出苗率为66.04%;两种方法种植的水稻株高差异不显著,在前期,旱穴直播秧苗的
