杂交晚稻旱育抛栽能改变“双夏”季节紧、任务重、劳动力紧张,及夏季高温、插秧后易败苗、影响返青、分蘖而导致产量不高等问题,因而它是一种省工、省力、增产、高效的新技术。一、塑盘旱育壮秧培育1.秧盘选用:根据杂交晚稻秧龄长特点,塑盘长×宽为60cm×33cm,塑盘孔穴数为308个,孔穴上口直径为2.6cm,穴底直径为1.2cm,孔穴深为2.4cm,穴底钻有0.3cm小孔,每个孔穴可培育一株秧苗,每亩用秧盘60只。
Hybrid late rice dry and throw throwing can change the “double summer” tight season, heavy tasks, labor stress, and the summer heat, seedlings after transplanting easy, affecting the green, tillering and yield is not high and so on, so it is a provincial workers, Effort, increase production and efficient new technologies. First, plastic plate nursery nursery seedling cultivation 1. Seedling Selection: According to the characteristics of hybrid late rice seedling age, plastic plate length × width of 60cm × 33cm, the number of plastic plate holes 308, the hole diameter of 2.6cm, the bottom hole Diameter of 1.2cm, the depth of the hole is 2.4cm, the hole drilled 0.3cm holes, each hole can cultivate a seedling, seedlings per mu with 60 plates.
