高海拔地区杂交稻茂优601栽培试验

A Cultivation Experiment for Maoyou 601, a Hybrid Rice Variety, in the Areas with Higher Elevation

2004年在海拔1 380m的安顺市西秀区对早熟杂交稻茂优601进行了栽培试验,试验选择密度和N、P、K施用量4个因素,每因素设3个水平,采用正交L9(34)设计。试验结果表明,杂交稻茂优601以每667m2密度1．85万窝,施碳酸铵 30kg、尿素7.5kg、磷肥50kg和氯化钾20 kg的处理为最优组合,产量可达604．5kg／667m2。

The cultivation experiment for Maoyou 601, an early hybrid rice variety, was conducted by using the L9 （34） orthogonal design at Xixiu district with an elevation of 1380 m in 2004. The results show that 604.5 kg/667m^2 of yield can be gained under the condition of 18. 5 thousand holes/667m^2 of density, 30 kg/667m^2 of NH4 CO2, 7.5 kg/667m^2 of urea, 50 kg/667m^2 of P2O5 and 20 kg/667m^2 of KCI.
