1999年在临澧县开展了超级杂交稻培矮 6 4 S/ E32的两个百亩高产栽培技术示范与研究 ,尽管遇到不利的气候影响 ,仍获得了好的收成。湖堰示范点产量为 830 0 .5kg/ hm2 ,新河示范点为94 0 0 .5kg/ hm2 ,比大面积栽培增产 30 .4 %～ 39.6 %。产量结构分析表明 ,足穗、大穗、总库容量大是培矮 6 4 S/ E32高产的重要保障。对其生育期表现、叶面积生长特点、施肥水平进行了调查 ,并讨论了此类特迟熟杂交组合在湘北栽培的适应性。 In 1999, two high-yield cultivation techniques demonstrating and researching on two hundred mu of super hybrid rice Pei’ai 64 S / E32 were carried out in Linqu County, and good harvests were still achieved despite unfavorable climate impacts. Lake dam demonstration yield of 830 0 .5kg / hm2, Xinhe demonstration point of 94 0 0 .5kg / hm2 than the large-scale cultivation yield 30.4% ~ 39.6%. Yield structure analysis shows that the full-spike, big spike and large total storage capacity are the important guarantees for Pei’ai 64 S / E32 high yield. The characteristics of their growth period, leaf area growth and fertilization were investigated. The adaptability of this late-maturing hybrid combination in northern Hunan was also discussed.
