水稻早糯新品系“2016”播插期栽培技术初探

Research on Sowing and Transplanting Date of Early Glutinous Rice Zaonuo 2016

为了更好地推广早糯新品系"2016",并为拟定一套适宜孝感糯稻生产栽培技术措施提供科学依据,特进行优质早糯新品系"2016"播种期和移栽期两因素栽培技术试验。结果表明,该品系播种期偏早的产量偏低、播种期偏迟的产量偏高、较迟播种、适期移栽的产量最高,太早播种和太迟移栽的秧龄最长,产量最低。其生育期受播种期影响较大,越迟播的生育期越短。在栽培方案选择上,其秧龄应宁短勿长。

In order to promote the extension of early glutinous rice Zaonuo ＂2016＂ and formulate a standard technology kit for the variety,an experiment of two factors with sowing and transplanting date was carried out.The results showed that the yields were significantly different among treatments.The highest yield was achieved with late sowing date and suitable transplanting date.The lowest yield came with very early sowing and very late transplanting when the seedling age was the oldest.The growth period of Zaonuo＂2016＂ was greatly influenced by sowing date.The later the sowing date,the shorter the growing period.This variety would prefer a shorter seedling age in production.
