杂交稻新组合花2优86的特征特性及其高产栽培技术

花2优86是福建农林大学作物科学学院育成的杂交稻新组合,具有高产、优质、适应性广等特点。该组合于2010年通过福建省农作物品种审定委员会审定。本文以花2优86为材料,Ⅱ优86为对照,研究了花2优86的分蘖动态、农艺性状及产量构成等生物学特性。结果表明:花2优86株高104.45 cm,全生育期129.4 d,实割产量7520.65 kg·hm-2,比对照Ⅱ优86增产6.09%,增产达显著水平。本文还总结了花2优86的高产栽培技术。

Characteristics of hybrid rice combination Hua 2 You 86 and its cultural techniques for high yield

Hua 2 You 86 was a high yield and high quality hybrid rice with wide adaptability developed by College of Crop Science of Fujian Agriculture and Forestry University. The combination was approved by the Fujian Crop Variety Examination Committee in 2010. In this paper, the developing of tiller, agronomic characteristics, yield traits of Hua 2 You 86 and Ⅱ You 86 （CK） were studied. The results showed that the plant height of Hua 2 You 86 was 104.45 cm, the growth duration of Hua 2 You 86 was 129.4 days. Compared with I/ You 86, Hua 2 You 86 had a slgnLqcant increase in the average yield （7520.65 kg · hm^-2 ）, 6.09% higher. Moreover, the high-yielding and high-resulting cultural technlaues were uromoted.
