“低氮高磷高钾”抗寒育秧(简称“一低两高”育秧),是通过栽培技术,提高秧苗素质,增强抗寒能力,以达到防止烂秧,培育壮秧的目的。两年来的实践证明了这种育秧技术确有一定的现实意义。怎样实施“低氮、高磷、高钾”,在生产上如何使秧田做到“全耕作层低氮”呢?如按照通常的做法,浅施基肥,追施秧针肥、断乳肥是不能达到全层低氮的要求。应该主要注意三项技术要点: “Low-nitrogen, high-phosphorus and high-potassium” cold-raising seedlings (referred to as “a low two-high” seedling) is through cultivation techniques to improve the quality of seedlings and enhance cold tolerance in order to achieve the purpose of preventing rotting seedlings and cultivating strong seedlings. Practice over the past two years proved that this seedling technology does have some practical significance. How to implement “low nitrogen, high phosphorus, high potassium”, how to make the production of seedling “low tillage”? As usual, shallow base fertilizer, topdressing needle fertilizer, weaning fat is Can not reach the full low-nitrogen requirements. Should pay attention to three main technical points:
