水稻两段育苗移栽法是通过采取提早育苗、两次移栽的非常规育苗技术,从而充分利用当地的有效积温,延长作物生长日期,扩大优质晚熟品种的种植范围,发挥晚熟品种的丰产特性。为验证该项技术的科学性与可行性及为今后的生产应用提供理论依据,我们对两段育苗移栽技术进行了试验研究 The two-stage rice seedling transplanting method adopts the unconventional seedling raising techniques of early seedling raising and twice transplanting so as to make full use of the effective local accumulated temperature, extend the crop growth date, expand the planting range of high-quality late-maturing varieties and give play to the yield characteristics of late maturing varieties . In order to verify the scientific and feasibility of the technology and provide a theoretical basis for the future production and application, we conducted two experiments on transplanting seedlings
