摘　　要：为给有机粳稻栽培中有机肥料施用技术的制定提供理论参考,开展农家肥(腐熟的人畜粪)施用技术研究。以高原粳稻楚粳28号为试验品种,采用盆钵种植,设置两个变量因子,即3种施肥量(100g/钵、200g/钵、300g/钵)和4种施肥方式,设施用复合肥料(颚中复合肥)和不施任何肥料两个对照,研究对高原粳稻的穗部性状、产量、收获指数和养分的利用率。结果表明:随农家肥施用量的增加,稻谷产量和收获指数也随着增加,当施肥量增加到4500kg/667m2时,其有效穗、实粒数、着粒密度、产量等方面都达到最优并且超过了施用复合肥料的穗部性状和产量,并能提高稻株对土壤中N的利用率;不同施肥方式间的产量差异不显著。在大田生产上建议农家肥的施用量为4500kg/667m2左右,施肥方式可根据农家肥积存的速度、劳动力的多少和田间具体情况而定。To provide theoretical reference for organic fertilizer application techniques to organic rice cultivation,farmyard manure（decomposition of human dung） fertilization technique is researched.The panicle traits of plateau japonica rice,yield,harvest index and the rate of nutrient were studied by plateau japonica rice chujing 28,using the pot planting,setting two variables,which were 3 kinds of fertilization（100g/ bowl,200g/ bowl,300g/ bowl）and 4 kinds of fertilization methods,using facilities for compound fertilizer（jaw in compound fertilizer） and without applying any fertilizer.The result showed that the grain yield and harvest index also increased with the increase of the amount of farmyard manure application.When the amount of fertilizer increased to 4500kg/667m2,the effective panicle,filled grain number,grain density,yield and other aspects achieved optimal and exceeded panicle traits and yield with compound fertilizer and improved utilization rate of the rice plants on soil N.The yield difference between different fertilization mode was not significant.The suggestion is that the amount of application of farmyard manure is about 4500kg/667m2 in the field of production,fertilization is according to how much manure accumulation rate and labor are,as well as the field specific conditions.
