摘要:

以籼粳杂交稻甬优1540为材料,研究了叠盘出苗稀播技术对单季晚稻产量的影响。结果表明,与农户传统不叠盘处理相比,应用叠盘出苗稀播技术的处理,秧苗素质提高,分蘖速度加快,有效穗数增加,可增产3.0%以上。

Abstract:

Effects of seedling raising technology with tray overlay in dark room and thin sowing on single cropping late rice were studied, using single cropping late rice Yongyou 1540 as material. The results showed that, the seedling raising technology with tray overlay in dark room and thin swoing could increase seedling quality, accelerate the speed of tiller, increase the number of productive panicles, and increase yield by 3.0% compared with traditional rice seedling raising technology.

Key words: rice, seedling raising technology with tray overlay in dark room , thin sowing, seedling quality, yield
