利用中杂汕优63培育再生稻,是中稻地区发挥杂交稻优势,挖掘汕优63增产潜力,增加粮食产量的一条有效途径。通过试验示范和大面积的生产实践,汕优63具有再生能力强,腋芽发生快,后发苗多,苗齐苗壮等优势,一般在中等肥力的条件下每蔸有再生芽10～12个,水肥条件好的可达15.7个。利用汕优63培育再生稻应抓好以下8项技术措施:1.早播早插适当早播早插不仅能提高汕优63头季的产量,而且有利于再生稻赶上季节,避开秋寒危
The use of Zhongzaosangying 63 to cultivate ratooning rice is an effective way to utilize the advantages of hybrid rice in middle rice region, tap the yield potential of Shanyou 63 and increase grain yield. Through experimental demonstration and large-scale production practice, Shanyou 63 possesses the advantages of strong regeneration ability, rapid axillary bud emergence, more seedling emergence after emergence, and seedling emergence and so on. Generally, there are 10-12 regenerated buds per gall under medium fertility conditions , Water and fertilizer conditions up to 15.7. The use of Shanyou 63 to cultivate ratooning rice should do the following eight technical measures: 1. Early sowing early planting appropriate early sowing early plug can not only improve the yield of Shanyou 63 first season, but also conducive to catch up with the season of regenerative rice, to avoid the autumn Cold danger
