Variety screening test of machine-harvesting ratooning rice

开展机收再生稻品种筛选试验,结果表明:甬优2640生育期适中,再生力强,抗倒性强,抗寒力强,产量稳定,米质好,再生季能安全齐穗,可在浦城县机收再生稻区作留低桩主推品种;隆两优华占再生力强,产量稳定,但生育期偏长,适合在浦城县南片低海拔地区作再生稻留高桩品种推广。

A screening test on machine-harvesting rationing rice varieties was carried out,the results showed that,‘Yongyou2640’had the characters of moderate growth period,strong regeneration ability,strong resistance to lodging,strong cold resistance,stable yield,good quality and safety heading in ratooning season,and so on,and it could be as main popularized variety with low stubble height in the area of machine-harvesting ratooning rice cultivation in Pucheng County.‘Longliangyouhuazhan’had strong ratooning ability and stable yield but too long reproductive period,and was suitable for remaining high stubble height of ratooning rice in low-elevation area of south part in Pucheng County.
