摘要
[目的]筛选适宜庐江县及相近区域的合适机插双季早籼稻品种。[方法]用井关播种流水线播种和井关PZ80D-25型插秧机进行25 cm行距和11 cm株距机插14个双季早籼稻新品种(系),重点研究同一机插条件下各品种在产量构成、生育期、茎蘖动态、抗纹枯病等差异。[结果]中早33、早籼402、嘉早15-128、浙辐203、嘉早15-143、中组143这6个品种较适宜在庐江县及相近区域作双季早籼稻机插种植。[结论]该研究为双季早籼稻毯状机插栽培技术推广应用提供科学依据。
[Objective] The research aimed to screen suitable for machine inserted double-season early indica rice varieties in Lujiang County and similar areas. [Method]A total of 14 double-season early indica rice varieties( lines) with 25 cm row spacing and 11 cm plant spacing were planted with well-planted sewer lines and Jing-zhuan PZ80 D-25 transplanter. The same machine inserted under the conditions of various varieties in the yield structure,growth period,stem tiller dynamics,resistance to banded sclerotial blight and other differences were focused on. [Result]Zhongzao 33,early indica rice 402,Jiazao 15-128,Zhefu 203,Jiazao 15-143 and Zhongzu 143 were more suitable for planting double-cropped early indica rice in Lujiang County and similar areas. [Conclusion]This study provides a scientific basis for popularization and application of double-season early indica rice blanket machine inserted cultivation.
