试验结果表明,采用稀播培育壮秧,平稳施肥的方法栽培沈农91,能提早抽穗和成熟,可获得较高的产量及经济效益,沈农91的高产栽培途径是穗粒兼顾。叶面积指数前期上升快而不过,中期稳定时间长,后期下降慢,这是取得高产的关键,沈农91最适叶面积指数为5.5～6.0。
The results showed that Shennong 91 could be cultivated by planting thin seedlings and cultivating strong seedling with stable fertilization. Earlier heading and maturity could be obtained earlier and higher yield and economic benefits could be obtained. The high yield cultivation method of Shennong 91 was both panicle and grain. However, the long-term stable period in the medium term and the slow decline in the late stage are the key to high yield. The optimum leaf area index of Shennong 91 is 5.5-6.0.
