Study on cultivation technique of hybrid rice plate breeding and throwing seedling

杂交水稻盘育抛秧栽培方式可以提高秧苗素质.大田抛秧在600盘/hm2密度下有较好的生物学性状和最高产量.与传统育秧移栽方式比,产量提高11.35%.“汕优63”的6年平均产量达7 499.25 kg/hm2.

The technique of plate breeding and throwing seedlings for hybrid rice is researched. Our experiment shows that hybrid rice plate breeding and throwing seedlings cultivation can enhance the quality of seedlings. It shows also that biological character is better and the yield is the highest when the density of throwing seedlings is 600 plate/hm^2. Comparing with traditional breeding seedlings, the yield can increase by 11.35% over the traditional one. The average yield of six years of ＂Shanyou 63＂ reached to 7 499.25 kg/hm^2.
