有机水稻生产中施肥效应试验研究

Study on the Fertilization Effect Test in Organic Rice Production

在网室内用盆栽试验多因素随机设计的方法研究了有机水稻生产中不同施肥品种及施肥水平对水稻生长的影响。结果表明,施用饼肥、堆肥和生物肥处理的植株与常规化肥相比,平均有效穗数低3.63%,每穗实粒数多11.01%;千粒重高1.84%,单株理论产量高9.44%。理论产量不存在显著差异。得出结论,按有机方式种植施用饼肥、堆肥和生物肥料的水稻与常规水稻不存在显著差异。

The effects of different fertilization varieties and different fertilization levels on the growth of organic rice were studied by multi-factor randomized design in petted-plant experiment in isolation chamber. Compared with plants treated by general chemical fertilizer, the characters of rice plants treated by cake fertilizer, compost and bio-fertilizer were obviously improved, exhibiting that the average effective spike lowered by 3.63%, grain number per spike increased by 11.01%, thousand grain weight increased by 1.84%, single plant yield on theory increased by 9.44% and there was no significant difference in theoretical yield. It was concluded that there was no significant difference between organic rice treated by cake fertilizer, compost and bio-fertilizer and general rice.
