Characteristics, High Yield Cultivation and Mechanical Harvesting with Loss Reduction of a New Japonica Rice Variety Song-836

松836是常规粳稻新品种,以松98-131为母本、松804为父本杂交,经10代系统选育而成。该品种具有优质、高产、多抗等特点,生育日数146 d,需≥10℃活动积温2750℃左右,适于黑龙江省第一积温带插秧种植。从旱育壮秧、移栽、水肥管理、病虫草害防治等方面总结介绍了其高产栽培技术。松836机械收获时含水量15%~17%、收获机械保持标准速度(1.5~2.0 m/s),收获损失率较低。

Song-836 is a new variety of conventional japonica rice,which was bred systematically for 10 generations,with Song 98-131 as the female parent and Song-804 as the male parent.This variety has the characteristics of high quality,high yield,multi-resistance and so on,the number of growing days is 146 days,need≥10℃activity accumulation temperature about 2750℃,suitable for planting seedlings in the first accumulation temperate zone of Heilongjiang province.The high-yield cultivation techniques were summarized and introduced from the aspects of drought-raising,transplanting,water and fertilizer management,disease,insect and weed control,etc.The harvest water content of Song-836 machinery was 15%~17%,and the harvest machinery maintained the standard speed(1.5~2.0 m/s),and the harvest loss rate was low.
