水稻免耕抛栽是在没有经过翻耕犁耙的稻田上进行双季稻抛栽的保护性耕作方法。它综合了免耕和抛秧的优点,集免耕技术、抛秧技术、除草技术、节水技术、秸秆还田技术于一身,是双季稻轻简栽培的综合体现。它具有4大特点:①省工省力,提高劳动生产率;②节本增效;③稳产高产;④节能降耗,保护农田生产环境。但是,水稻免耕抛栽也存在一些不足,如抛秧后立蔸慢、分蘖迟、生育期延长等弊端。因此,水稻免耕抛秧要获得高产稳产,必须过好以下“5关”: Rice No-till throwing is a conservation tillage method for double-cropping rice in paddy fields that have not undergone tillage rakes. It combines the advantages of no-tillage and throwing seedlings, set no-tillage technology, throwing seedling technology, weeding technology, water-saving technology, straw in a field of technology, is a double-cropped rice cultivation reflects the light. It has four major characteristics: ① provincial labor-saving, improve labor productivity; ② section of the efficiency; ③ stable and high yield; ④ energy saving, protection of farmland production environment. However, no-tillage rice throwing throwing there are some shortcomings, such as throwing seedling stand slow, late tillering, growth period and other shortcomings. Therefore, no-tillage throwing rice to get high and stable yield must be better than the following “5 off ”:
