杂交稻特优233“种三产四”丰产工程百亩连片示范与“631”高产栽培技术

2009年早造在北流市民乐镇罗政村开展特优233＂种三产四＂百亩连片高产栽培示范。项目结合当地的土壤肥力,以纯N为计算单位,采用前期施纯N肥占60%、中期30%、后期10%的＂631＂高产栽培技术,特优233平均产量达10.32t/ha,比对照特优5058增产2.80t/ha,增产37.16%,达到了＂种三产四＂丰产工程项目目标产量,示范获得成功。

Demonstration of "Planting Three to Produce Four" high-yielding project on hybrid rice Teyou 233 and its high yield cultivation technology using "631" nitrogen application

A 100-mu area high-yield demonstration projects ＂planting three to produce four＂ for early rice variety,viz.,Teyou 233 was conducted in Luozheng Village of Minle Township,Beiliu City,Guangxi,in 2009.Based on the soil fertility test,the nitrogen fertilizer was applied @ 60%,30% and 10% at early,middle and late stage,respectively,in the demonstration process.Variety Teyou 233 recorded the average yield of 10.32t / ha with an increase of 37.16% over the control variety Teyou 5058.The results achieved the objective yield of ＂planting three to produce four＂ high-yield production.
