摘要
研究了“沪玉糯3号”在不同播种期、不同密度、不同栽培方式和不同施肥水平条件下的农艺性状和产量表现。结果表明，要获得产量750kg／667m^2左右的优质鲜食果穗，在崇明露地栽培以4月6～16日播种为宜，采用覆膜栽培，可提早到3月15日左右播种；密度为3800株／667m^2左右时产量及果穗商品性较佳；肥料运筹中应施足基肥，早施苗肥，重施穗肥，满足整个生长过程对肥料的需要。
Field experiments with waxy corn cultivar ＂Huyunuo 3＂ were carried out in order to study the effects of seeding dates, planting densities, cultural methods and fertilizer rates on agronomic characters and yield of the cultivar. The results showed that in Chongming area of Shanghai the suitable seeding time was between April 6-16 to gain a high table ear yield of about 750 kg/667 m^2 ,and the seeding date could be on March 15 or so if mulching film was used. At the density of about 3 800 plants/667 m^2 , the ear yield and quality were comparatively good. In order to meet plant growth requirement for fertilizer, basal fertilizer should be adequate, and fertilizer should be applied early at seedling stage and heavily at heading stage.
