天优华占系中国水稻研究所用天丰A与华占配组育成的杂交稻组合。2008年通过国家农作物品种审定委员会审定(国审稻2008020)。2009年由松溪县种子管理站引进在松溪县作烟后稻试种,表现高产、稳产、分蘖力强、生育期适中、农艺性状好、米质优等特点。2010年、2011年该组合在我县较大面积示范推广种植,2012年开始进行机插栽培,比手工插植增产增效显著,一般增5%左右。现将其种植表现及机插栽培要点总结如下。
Tianyuhua occupies the China Rice Research Institute Tianfeng A and Hua Zhanpai bred hybrid rice combinations. In 2008 through the National Crop Variety Approval Committee (National review rice 2008020). In 2009, the Songxi County Seed Management Station was introduced as a model for post-harvest tobacco trial in Songxi County, showing high yield, stable yield, strong tillering ability, moderate growth period, good agronomic traits and excellent quality of rice. 2010, 2011, the combination of large areas in my county to promote the demonstration model planting in 2012, machine-inserted cultivation than hand planting a significant increase in productivity and efficiency, generally increased by about 5%. Now its planting performance and machine-inserted cultivation points are summarized below.
