摘要:
随着人民生活水平大幅提高，近几年市场对香米的需求量不断增加，香型水稻绥粳4号种植面积越来越大，很多农民在种植绥粳4号时，在肥料的使用上有很大的盲目性，尤其是氮肥。对此，该试验设计低﹑中﹑高3个氮肥量和氮肥基蘖肥与穗粒肥4个不同比例处理的研究。结果表明：绥粳4号在高肥，氮肥基蘖肥与穗粒肥的比例7∶3条件下分蘖较多，空瘪率较低，产量表现最好。
Abstract:
With the people’s living standards greatly improved in recent years,the market demand for rice was increased,planting area of fragrant japonica rice Suijing No.4 was increasing more and more,many farmers had blindness in fertilizer used,especially nitrogen.Therefore,three different nitrogen fertilizer account treatments and four different ratios of basic tillering fertilizer and grain fertilizer treatments were studied.The results showed that under the condition that nitrogen fertilizer was at high level,ratio of basic tillering fertilizer and grain ferterlizer was 7∶3,the tillers were more,the empty flat rate was lower and the yield expression was the best.
