【摘要】 用中晚熟早稻品种(组合)与郴晚3号等晚稻品种混合栽培,研究不同品种搭配及种子不同混合比例下的早晚稻产量.结果表明,混合比例以早七晚三较为理想,中晚熟早稻品种(组合)配郴晚3号混栽的产量最高,两季产量为11130~13560 kg/ha。这种混合栽培是一项稳产、增收、省力、低耗、高效的栽培方法.

【Abstract】 By means of the mixture practice of cultivation with early-rice(mid or latematurity varteties)and late-rice(Chengwan No.3 et al),the effects of different variety com-binations and their seed ratio on two seasons,yield were studied.The result showed that suit-able seed ratio of mixture was 7(early-rice)to 3(late-rice).The highest yield was obtainedin the combination of early-rice(mid or late maturity variety)and corresponding late-rice(Chengwan No.3),and two seasons,yield was as high as 11 130~13 560 kg/ha.The mix-tural cultivation was a possible path to economic and effective cultual practice with stableyield,increased income and less labour.
