“壮秧三分收,秧好半年稻”。能否育出壮秧,炼苗是关键的一环。为了适应当前水稻生产上铲秧移栽动手早,需苗集中的新特点,炼苗必须做到早炼苗,炼小苗。我们公社一般在3月下旬即开始塑料薄膜育苗,4月15日前后当秧苗长出二片叶时,就进入了炼苗阶段。早炼苗,炼小苗的好处是: 1.增强秧苗的适应能力。秧苗大小不同,耐低温能力也不一样,小苗耐低温能力强,早炼苗、炼小苗,延长炼苗时间,可增强秧苗的适应能
“Strong seedlings third harvest, good seedlings six months rice.” Breeding strong seedlings, refining is a key part. In order to adapt to the current rice production shovel transplant transplanting early, need to focus on the new characteristics of seedlings, hardening must be early hardening, refining seedlings. Our communes generally began in late March plastic film nursery, April 15 when the seedlings grow two leaves, they entered the refining stage. The advantages of early hardening seedlings, refining seedlings are: 1. To enhance the adaptability of seedlings. Seedlings of different sizes, low temperature tolerance is not the same, low temperature ability of seedlings strong, early hardening, refining seedlings, to extend the hardening time, can enhance the adaptability of seedlings
