利用早稻嘉育９４８和嘉育２９３，晚稻甬粳１８和丙９７－２０９，进行连作稻旱育抛栽的茬口搭配研究。结果表明，与旱育秧手插相比，旱育抛栽的水稻有效分蘖终止期提早２～５ｄ，最高苗增加７７．７万～１１４．２万／ｈｍ２，生育期延长１～２ｄ，有效穗增加１５．２万～６６．７万／ｈｍ２，每穗总粒增加１．６～６．０３粒；旱育抛栽连作水稻的品种搭配组合以嘉育９４８与丙９７－２０９产量最高。 Using early rice Jiayu 948 and Jiayu 293, late rice Ningbo Japonica 18 and C 97-209, continuous cropping paddy cultivation throwing stubble research. The results showed that compared with the dry-seedling planting, the termination of effective tillering and tillering in dry-spring planting and throwing-off rice was 2 to 5 days earlier, the highest seedling increased from 777,000 to 1,142,000 / hm2, the growth period was extended for 1 to 2 days, An increase of 152,000 ~ 667,000 / hm2, grain per panicle increased 1.6 ~ 6.03 grains; dry cultivation throwing planted with rice varieties with the combination of Jiayu 948 and C 97-209 highest yield.
