摘要
将江西省农业科学院农业工程研究所研制的机插水稻育秧营养基质分别在江西省4个试验点进行了早稻和晚稻2种育秧方法的对比试验,比较分析其秧苗素质、茎蘖动态、产量和产量结构。试验结果表明:使用营养基质育秧的秧苗植株矮壮、叶绿素含量高、根数多、秧苗生长均匀整齐、茎蘖数多,早稻平均增产2441.45kg/hm2,平均增产率为6.3%,晚稻平均增产504.9kg/hm2,平均增产率为7.0%。
By using institute of trix for early rice and late rice made on the quality of seedling agricultural engineering, Jiangxi academy of agricultural sciences developed nutrition maseedling-raising in four experimental sites of Jiangxi province, compare analyses were , stem tillers, yield and yield structure. The results showed that the seedlings used nutrition matrix was stock, much chlorophyll, vigorous roots, uniformity of seedling growth and many tillers, early rice increased average 29.43 kg/666.7 m2, the average increase rate was 6.3% and late rice increased average 35.66 kg/ 666.7 m2, the average increase rate was 7.0%.
