摘要:

以丰两优1号为材料,对比研究了规格化育秧和大田泥浆育秧两种育秧方式对水稻秧苗素质、栽插质量和产量的影响。结果表明,大田泥浆育秧的秧苗素质好于规格化育秧,但秧苗插前均匀度合格率低于规格化育秧;规格化育秧栽插质量高于大田泥浆育秧,表现为其伤秧率和漏秧率明显低于大田泥浆育秧,均匀度合格率和作业效率高于大田泥浆育秧;产量方面,规格化育秧的水稻理论产量和实际产量均高于大田泥浆育秧,差异显著,主要是因为规格化育秧的有效穗数明显高于大田泥浆育秧。

Abstract:

In order to provide a theoretical basis and technological support for choosing the suitable seedling raising method for rice, an experiment was conducted to study the effects of standardized seedling raising and field mud seedling raising on seedling quality, transplanting performance and yield of rice using Fengliangyou 1 as material. The results showed that the field mud seedling raising method resulted in better seedling quality but lower seedling evenness compared with the standardized seedling raising method. The standardized seedling raising method displayed better transplanting performance, such as lower rate of injury seedling and missing seedling, and higher evenness and efficiency. Due to higher effective panicles, the yield of standardized seedling raising method was significantly higher than that of the field mud seedling raising method.

Key words: rice, seedling raising method, seedling quality, transplanting performance, yield
