| 摘 要： | 【目的】在＂稻鸭共育＂有机稻生产模式基础上,结合广西在优质稻生产优势,探索＂猪—鸭—蚯蚓—优质稻＂有机稻生产模式,并对该模式下的有机稻栽培技术进行研究,以丰富广西的有机稻生产模式,为广西有机稻生产提供理论依据。【方法】以＂桂育4号＂为参试品种,采用裂区设计,设3个施肥量（3750、4500、5250kg/ha）与3种种植密度（30.0、33.0、37.5万穴/ha）,测定株高、有效穗数、每穗粒数、结实率、千粒重和产量等。【结果】各处理产量都在5.25t/ha以上,最高产量达到6972.0kg/ha。施肥量从3750.0～5250.0kg/ha,种植密度从30.0万～37.5万穴/ha,产量均逐渐增加,早、晚季施肥量为5250.0kg/ha、种植密度为37.5万穴/ha的产量最高。【结论】＂猪—鸭—蚯蚓—优质稻＂有机栽培模式及有机稻栽培技术能获得较高产量,值得推广应用。

| Abstract: | Objective]In order to develop organic farming and to enhance organic rice production in Guangxi, a new high quality organic rice cultivation technique has been developed using organic manure made from pig excreta, duck droppings and earthworms. Method]A two factor (organic manure and planting density) experiment was conducted using rice variety Guiyu 4 to develop a new organic rice cultivation technique. Plant height, effective panicle number, grain number per spike, seed setting rate, 1000-grain weight a... |
