试验结果表明,采用稀播培育壮秧,合理稀植,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。群体前期生长快而不过,叶面积指数中期接近最适程度(5.5),后期下降慢,这是取得高产的关键。辽宁省多数品种采用这种技术栽培,都可以获得增产增收的效果。 The results showed that planting thinning sowing seedlings, reasonable planting thin, smooth fertilization method Shennong 91 cultivation, early heading and maturity, access to higher yields and economic benefits. Shennong 91 high yield cultivation methods are both grains and ears. However, the leaf area index approached the optimum level in the medium term (5.5) and the decline rate was slow in the late stage, which is the key to high yield. Most varieties of Liaoning Province using this technology cultivation, can obtain the effect of increasing production and income.
